(From the Prcceedings of the Geological Society of London.) In 1843-44, Sir W. E. Logan ascertained, and published in his Report* for the latter year, the occurrence of a series of beds of Devonian age in the Peninsula of Gaspe, Lower Canada, contain- ing fossil plants, apparently of the land, and some of them evidently in situ. Nothing was done toward the precise determin- ation and description of these remains until 1856, when Sir William kindly permitted the writer of this paper to examine his collection, and to describe before the American Association for the Advancement of Science the most interesting specimen contained in it — a fossil trunk exhibiting a very remarkable and previously undescribed coniferous structuref . The other specimens in the collection were so fragmentary or obscure, that it was not deemed expedient to attempt their description before studying them (as all fossil plants should, when practicable, be studied) in the rocks in which they occur. With this view I visited Gaspe in the past * Report of Progress of Canadian Geological Survey, 1844, p. 36, and Appendix. t Proceedings of American Association, 1856, p. 1T4. Canadian Nat. 1 Vol. V. No* 2 Devonian Plants, summer, and examined the localities indicated on the plans and sections of the Geological Survey. The facts and specimens thus obtained will probably be fully described and illustrated in one of the forthcoming Decades of Canadian Fossils ; and in the mean- time I propose to notice some of the species observed, which appear to be of especial interest in the present state of our gen- eral knowled^'C of the Devonian flora. Before proceeding to these descriptions, it may be necessary to state that the deposit in "which the fossils occur consists of sand- stone and shale, of various colours and textures, with some con- glomerate and thin-bedded coarse limestone, and a seam of bitu- minous coal, one inch in thickness. The whole series is estimated by Sir W. E. Logan at VOOO feet of vertical thickness. It rests on Upper Silurian rocks, and underlies unconformably the con- glomerates which here form the base of the Carboniferous system. Some of the beds, especially in the lower part of the series, contain marine fossils of Lower Devonian forms, which are now in process of examination by Mr. Billings of the Geological Survey. The greater part of the beds are, however, destitute of marine fossils, and present appearances indicative of shallow water and even of land-surfaces. Some of the species of plants occur throughout the whole thickness; but the bed of coal and most of the plants in situ are found in the lower and middle portions of the series. Detailed sections and descriptions of the beds will be found in the Report above referred to. 1. PsiLOPHYTON, gen. nov. (Figs. 1 & 2.) Lycopodiaceous plants^ hrancTiing dicJiotomousli/, and covered with interrupted ridges or closely oppressed minute leaves ; the stems springing from a rhizoma having circular areoles^ sending forth cylindrical rootlets. Internal structure : an axis of scalari- form vessels, surrounded hy a cylinder of parenchymatous cells and hy an outer cortical cylinder of elongated wcody cells (pros- enchynui). Fructif cation probably in lateral masses, protect- ed by leafy bracts. The most remarkable and interesting plant of the formation is one which, I believe, has frequently been observed and described elsewhere from fragmentary specimens, but which occurs in the Devonian Plants, Fig. 1 a Fig. 1 / Fig. 1 d Fig. 1 c Fig. 1 6 Fig; 1 e Fig. l.^Psilophyton princeps. a, rhizome ; 6, stem ; c, termination of branches ; d, vernation e, fructification ; /J restoration. 4 Devonian Flants^ Gasp6 sections in a state of perfection unusual with palseozoie plants. It is characterized by slender, bifurcating, ridged sterns^ proceeding from a horizontal rhizoma, which sends forth numerous rootlets. The rhizomata, evidently in situ, clothe some beds of indurated clay with a mat of creeping and occasionally bifurcat- ino- cylindrical stems, filling the beds below with their vertical rootlets. They attain a diameter of an inch or more, though usually smaller, and a length of at least three feet. They are irre- gularly dotted with minute linear punctures, the marks probably of ramenta ; and at intervals there are circular areoles with central pits, like those of Stigmaria, but irregularly disposed, and giving origin to the roots, which, however, unlike those of Stigmaria, subdivide in descending into the soil. Apart from the stems, these rhizomata might be included in the genus Karstenia or Halonia, or even as abnormal species in Stigmaria (iig. 1 a,). The aerial stems vary from a fourth to a tenth of an inch in diameter at their origin, rise obliquely from the rhizoma, and bifurcate very regularly. The extreme points divide nearly at rit"^ht angles, and in some, probably young, branches the ultimate branchlets bend into a spiral curve with a somewhat unilateral arrangement of the leaflets. In the shale overlying the small coal-seam above-mentioned, there are immense numbers of these little branchlets, rolled so closely as to resemble spiral shells Thev probably indicate a circinate vernation like that of ferns. (See figs. 1 h, c, d) The surface of the stems is very smooth and glossy, quite destitute of scars, but marked with numerous inter- rupted ridges spirally arranged, and sometimes seen to project a little at the upper ends, as if rudimentary leaves. This leaf-like character is more distinct toward the extremities of the branches; but the leaves are not sufficiently well preserved to show anything more than that they are slender and acicular. The greater part of the specimens are flattened, with the epider- mis alone preserved in a coaly state ; but a few fragments were found with the internal structure remaining. It consists of a slender axis of scalariform vessels, surrounded by a space now occupied by calcspar, but showing in parts the remains of a loose cellular tissue. Externally to this is a cylinder of well-preservedy elongated, woody cells, without distinguishable pores, but with traces of very delicate spiral fibres. (Fig. 2 g, h^ i, k.) The structure and external appearance above described indicate affinities with the Lycopodiacem^ and especially with the genus Devonian Plants* Fsilotum*y witb which these plants very closely correspond in all except their rhizomes and the circinate terminations of the branchlets. The name proposed above is intended to express this relation, as well as the most apparent distinction between these plants and those of the genera Lyco2Jodites and Selaginites\. To the species above described I would give the name of Psilophy- ion princeps. I have attempted a restoration of its general ap- pearance in fig. 1 /. in Fig. 2 S Fig. 2 h Fig. 2 i Fig. 2 k Fig. 2 g", longitudinal section of stem, nat. size ; h, cortical cells (300 diams.) ; i, parenchyma (300 diams.) ; fc, scalariform tissue of axis (300 diams.) Some of my specimens appear to indicate a second species, characterized by more robust stems, more finely ridged, and having slender alternate branches, which bifurcate frequently and usually bend downward. The specimens are not well preserved, but are very distinct from P, princeps^ while probably generically related to it. I would name this species P. rohustius. * See Brongniart, V^g. Fos. vol. ii. pis. 6 & 11. I have been favour- ed by Prof. Gray, of Harvard College, with specimens of P. flavidum from Tahiti and P. triquetrum from Australia, which closely resemble the fossils in structure and surface-markings. t I should have preferred the term " Psilotites ; " but this has been preoccupied by a Jurassic plant, of which, however, I cannot find any detailed description. See linger, Gen. et Spec, &c. p. 279 ; Brongniart* Tableau des Genres, p. 41. 5 Devo7iian Plants. Neither of the species exhibit distinct fructification. Certain obscurely cuneate carbon aceous"spots attached to the sides of the branches of P. princeps are, perhaps, of this character ; and the object represented in fig. 1 e, which appears to be thus attach edr may be an example in better preservation than usual. It consists, of four thick lanceolate leaves or bracts with single midrib, arising from a flattened carbonaceous patch, which shows traces of similar leaves on its surface. These leaves or bracts have evidently enclosed the fructification of some lycopodiaceous plant ; and from their association with PsilopTiyton princepSj I regard it as highly probable, though by no means certain, that they belong to that species. The rhizomata of PsilopTiyton princeps occur in situ in a number of argillaceous beds, in a manner which shows that they crept in immense numbers over flats of sandy clay, on which their graceful stems must have formed a thick, but delicate, herbage, rising to the height of from two to four feet. The rhizomes and the bases of the stems may possibly have been submerged ; but I should infer, from the appearance and structure of the latter, that they were rigid, woody, and perhaps brittle. In many beds in which the rhizomes have not been distinctly preserved, the vertical rootlets remain, producing an appearance very similar to that of the Stigmarian under-clays of the coal-measures. Sir W, E. Logan has noted in his detailed sections numerous cases of this kind. When broken into fragments and imperfectly preserved, Psilo- pTiyton princeps presents a variety of deceptive appearances. When perfectly compressed in such a manner as to obliterate the mark- ings^ it might be regarded as a dichotoraous fucoid or a flattened root. When decorticated and exhibiting faint longitudinal striae^ it presents, especially when the more slender branchlets are broken off, the aspect of a frond of ScTiizopteris or TricTiomanites, When rendered hollow by decay, it forms bifurcating tubules, which might be regarded as twigs of some tree with the pith removed. Lastly, the young plants might be mistaken for ferns in a state of vernation. In all conditions of preservation, the stems, rhizomes, androotlets, if separated, might be referred to dis- tinct genera. I have little doubt therefore that many imperfectly preserved Devonian plants of this general form, noticed under various names by authors, may belong to this genus, and some of them to the species above described. In particular I may refer Devonian Plants, 7 to certain dichotomous fucoids in the genera Fucoides and Chon- drifes ; to a plant from the Hamilton Group of New York, figured by Vanuxem in his Report, p. 161 ; to the dichotomous roots from Orkney and Caithness described by Mr. Salter in the ' Proceedings' of this Society for last year; and to the bifurcating plants with curved tendril-like brancblets figured by Hugh Miller, ' Old Red Sandstone,' plate 7, and 'Testimony of the Rocks, p. 434. From the description in the former work, Chap. 5, it would appear that the author had observed not only the stems but the rhizomes with their Stigraaria-like areoles, though without suspecting them to belong to the same plant. I have little doubt therefore that materials exist in the Old Red Sandstone of Scotland for the reconstruction of at least one species of this genus. Various fragments which I have collected induce me to believe that it may be found also in the Lower Coal-measures. I have noticed above the resemblance of flattened specimens of Psilopliyton to ferns of the genus Trichomanites (Goeppert.) To this genus, indeed, I was disposed to refer the specimens, until I found that the internal structure was lycopodiaceous, and that the branching filaments are true branchlets covered with minute leaves, A comparison of the plants above described with Tricho- manites Beinertii of Goeppert, and SpJienopliyllum {T.) hijidum of Lindley and Hutton, will show at a glance the strong resem- blance that subsists ; and, since the specimens on which these spe- cies are founded do not appear to have exhibited internal structure or venation, I think it still admits of a doubt whether they are really ferns. By way of further caution on this point, I may remark that in flattened stems, either of Psilotum or of its ancient relative, the slender woody axis may leave a mark resembling the nervure of a leaf, and thus complete the resemblance to a frond of Trichomanes. Since writing the above. Professor G. S. Newberry has kindly pointed out to me the close resemblance between the first species above described and Haliserites Dechenianus of Goeppert ('Flora der Uebergangpgebirges,' p. 88). I can scarcely doubt that this so-called fucoid is in reality a plant of the genus above described, but in such a state of compression that the stem appears like a narrow frond, and the woody axis as a midrib. As this plant is said to occur very abundantly at certain levels in the Devonian Series of the Rhine, if my suspicions as to its nature are correct 8 Devonian Plants* further examination might disclose its rhizomes, leaves, or fruc- tification.* 2. LEPIDODENDROlir. (Fig. 3.) A single species of this genus is found rather plentifully in the beds containing the plants just described, and is distinct from any that I have observed in the Coal-formation. The specimens observed were all of small size and fragmentary, nor was their state of preservation very good, though most of them were Fig. 3 a Fig. 3 h Fig. 3 c Fig. 3. Lepidodendron Gaspianum. a, decorticated stem and leaves ; bj areoles ; c, small branch and leaves. accompanied by the leaves. In specimens about two inches in diameter, the areoles are two lines in length and one in breadth, and placed closely together. They are elliptical, acuminate, with central leaf scar, the form and markings of which could not be perceived. The leaves are thick at the base and short, slightly ascending, and then curving downward. The branches are slender, straight, and very uniform in thickness in the portions observed. This plant may be identical with the L. Chemungense of Hall, from the Devonian rocks of New York ; but I am not aware that any specimens of that species hitherto observed show the leaf-scars or leaves; and, when these are obtained, should the present species prove distinct, I would name it L. Gaspianurrv\, Its characters, as above stated, are represented in figs. 3 a-c, * It is possible that some of the fragments, from the Devonian of the Thiiringerwald, included by Prof. Unger in his order RhachiopteridecB may be allied to Psilopkyton. (See Denkschr. Kais. Akad. Wissen. Wien, vol. xi. p. 139.) f L. (Sagenaria) Veltheimianum, another ancient and widely distri- buted species, resembles the above in the form of the areoles and position of the scars ; but the leaves and young branches diflFer, and my speci- mens show no median furrow in the areoles. L. nothum (Unger) also seems closely allied. Devonian Plants. 9 3. Prototaxites, gen. nov. (Fig. 4.) Woody trunks with concentric rings of growth and medullary rays. Cells of pleurenchyma scarcely in regular series^ thich- walled, and cylindrical^ with a double series of spiral fibres. Disc-structure indistinct in the specimens observed. I propose the above generic appellation for a tree having the spirally marked cells characteristic of the genera Taxites and Spiropitys of Goeppert, but differing from any conifer known to me in the cylindrical form and loose aggregation of the wood- cells, as seen in the cross-section, in which particular it more Fig. 4 a C OJD OO^ gO0 O..Qytf [i:iii'^ri% Fig. 5 b Fig. 5 c Fig. 4.

A fine silicified trunk of this tree was brought from Gaspe by Sir W. E. Logan, and was shortly described in the ' Proceedings of the American Association ' for 1856. 10 Devonian Plants. The specimen is nine inches in diameter, and presents through- out a series of rings of growth, rather more than one-tenth of an inch in average thickness. Under the microscope, the cross- section exibits cells perfectly circular in outline, not crowded, but becoming much smaller at the margins of the rings of growth, where some large irregular openings perhaps represent resin- ducts. The medullary rays are marked by clear structureless spaces. In the longitudinal section, parallel to the medullary rays, the wood-cells are seen to be much elongated, and to terminate in conical points ; and their sides are covered with the remains of a double series of spiral fibres, among which are a few scattered roundish spots, which perhaps indicate a single row of discs*. The cells of the medullary rays have been entirely disorganized ; but the space which represents them in a tangential slice, shows that they must have consisted of several rows of cells. (Figs. 4 a—c.) In my late visit to Gaspe, I was so fortunate as to find a second tree of this species imbedded in the strata, though having its structure in a less perfect state of preservation than the specimen above described. It was in a prostrate position, the trunk lying S. W. and N. E., in a thinly bedded, crumbling, pyritous sand- stone. The trunk is silicified, one foot five inches in its greatest diameter, and eleven inches in its least, the difi'erence being due to compression ; a branch five inches in diameter sprang from its side. On the external surface was a thin layer of crumbling coal, probably representing the bark. No pith was perceptible ; but there was a channel or depression along the upper surface, as if a pith-cavity had existed and, when the wood became softened by decay, had given way to pressure. The age of this tree, as in- dicated by its rings of growth, would be about one hundred and fifty years ; so that, though the tissue appears lax, it was not of more rapid growth than in modern conifers. The growth-rings also in the specimen previously described, as well as in this, are well marked, indicating a decided difi'erence of temperature in the seasons of the Devonian year. I cannot propose for this monarch of the old Devonian forests of Gaspe a better or more appropriate name than that of its discoverer, and shall therefore name it Prototaxites Logani. * This disc-like structure was first pointed out to me by Mr. Poe, of Montreal, a very zealous and successful microscopist. Devonian Plants, 11 With respect to the affinities of the genus, I can only say that the markings on its wood-cells most nearly resemble those of the two genera of fossil Taxine trees above-mentioned, which are, however, found in much more modern geological formations. Among recent trees known to me by specimens or figures of their tissues, Taxus haccata and Torreya taxifolia most nearly resemble the Gaspe fossil. In the meantime, therefore, it may be included in the subfamily Taxinece. I could detect no leaves or fruit likely to belong to the species ; but this is not wonderful, since in the Coal-formation the wood of conifers is very abundant, while their foliage is extremely rare. Before leaving this ancient taxine conifer, it may be useful to notice the deceptive appearances which its wood presents when, imperfectly preserved. In some parts of my second specimen the woody tissue has been entirely obliterated, and is replaced by a kind of oolitic concretionary structure, apparently connected with the presence of iron-pyrites. In other portions the wood seems to have been resolved into a homogeneous paste before silicifica- tion ; and this, being moulded on minute granular crystals of quartz, assumes the aspect of a tissue of fine parenchymatous cells — a deceptive appearance very common in badly preserved fossils penetrated by calcareous or silicious matter. In other parts of the specimen the cell-walls remain, but in an opaque coaly condition, which conceals their spiral fibres and discs. I am not quite certain that this last form may not represent the natural state of the heart-wood of the tree. In the first specimen, ob- tained by Sir W. E. Logan, the whole trunk appears to be well preserved, with the exception of the medullary rays-, 4. PoACiTES, Knorria (fig. 5), Carbonized Wood (fig. 6), etc. In addition to the plants above described, the Gaspe sections contain, especially in the beds near the coal-seam, abundance of what seem to be long parallel-sided leaves, with delicate longitudinal striae, and varying from a Fig. 5 a fourth of an inch to an inch, in breadth. Thev may be placed provisionally in the genus Poocites, but are perhaps leaves of Nceggerathia or Cor- daites. There is also in the Collection of the Geological Fiff 5 6 Survey of Canada a remarkable fragment, covered Fig. 5. Knorria ? with sharp, flat, angular scales. Were it not for b, magnified. ^^^ carbonaceous character, I should be inclined 12 Devonian Plants, to regard it as of animal rather than vegetable origin. If a plant, it must, I presume, be referred to the genus Knorria (see fig. 5). In the same collection is a flattened and obscurely marked stem, from rocks of the same age at Kettle Point, Lake Huron. Its markings are scarcely sufficiently distinct for description, but can- not be distinguished from those of some of the varieties of Knorria imbricata. Another suite of specimens in the Museum of the Geological Survey indicates the existence of a large plant, the precise nature of which it is perhaps at present impossible to determine. One of the specimens from Gaspe has the aspect of a long flat- tened trunk, having in a few places the remains of a carbonaceous coating, presenting longitudinal ribs like those of Calamites, It is crossed at intervals by markings not quite at right angles to the sides of the stem, each of which consists of a sharp ridge with a furrow at either side. The specimen is four inches in breadth and about four feet in length. Other specimens from Kettle Point vary from five inches to one inch in breadth ; and some of them show traces of longitudinal ribs, but others are quite smooth, or marked only by the rhombic structure-lines of the coaly matter. All show transverse or diagonal ridges, though some of these seem to be merely cracks filled with mineral matter. Crushed Calamites, in a very bad state of preservation, might assume these ap- pearances; but, until better specimens occur, the true nature of these plants must remain doubtful. They are very possibly of the same nature with the Calamite-like stems described by Miller in his 'Testimony of the Rocks,' p. 439. In every part of the Gaspd sections, beds occur having their surfaces thickly covered with fragments of carbonized vegetable matter, evidently drifted by the currents which deposited the sand composing the beds. A large proportion of these comminuted plants belong to the genus Psiloijhyton ; but many are frag- ments of the wood of larger vegetables. Nearly all are in a very imperfect state of preservation ; and most of those that retain the'.r structure show a scalariform tissue similar to that represented in fio;. 6, and Pig- 6. '' . . probably belong to the a^lso^ Lepidoden- Fig. 6. Scalariform tissue dron. Others exhibit elongated woody (magnified 300 diams.) ^^^j^^ ^.^j^^^^ ^^^^^^ markings, perhaps Devonian Plants. 13 from the cortical portion of the same genns, or possibly conifer- ous*. Another form of carbonaceous matter, abundant in some of the sandstones, consists of scaly fragments resembhng the remains of decayed cones, probably Lepidvstrohi. The great abundance of vegetable fragments throughout an immense thickness of rock^ indicates the existence of extensive land surfaces clothed with vegetation, though this apparently con- sisted of but a few species. The small bed of coal occurring in the lower p;5rt of the section, is composed entirely of irregularly lamin- ated shining coaly matter without mineral charcoal. From its appearance and the vegetable remains in its underclay, I infer that it consists principally of the accumulated rhizomata of Psilophy- to7i, in situ. Its roof-shale is filled with the Poacites-like leaves before mentioned, and with stems of Psiloj^hyton ; and it is remar- kable that these last are in great part coiled up in the state of vernation, as if overwhelmed by a succession of spring floods. 5. Animal Remains, Rain-marks, etc. The animal remains found in the plant-beds were Entomostraca (Beyrichia), Spirorhh (resembling that of the coal-measures), Worm-tracks, and Ichthyodorulites [Onchus and Machceracan- thus\). In one of the beds above the coal Sir W. E. Logan found a few brachiopodous shells, apparently identical with those at the base of the series, and also some remarkable transversely marked furrows, which may have been produced by worms or by marine gasteropods. Near the upper part of the section, where the plants become more rare, and the rocks are more abundantly tinged with the red peroxide of iron, the beds are plentifully and often very grotes- quely marked with ripple-furrows, shrinkage-cracks, and current- lines. In one or two beds there are surfaces covered with round- ed projections resembling casts of rain-marks; and in proof that this is their true character, the surface being irregular, we have not only the rain-marks themselves, but the little rills formed by the gathering drops as they rolled along, in this one of the most ancient showers of which we have as yet any geological record. The general character of the conditions indicated by the Dev- onian rocks and flora of Gaspe does not differ materially from that * Aporoxylon (Unger). t Prof. Newberry regards one of these as identical with his MachcBra' eanthus sulcatus from the Devonian of Ohio. 14 Catalogue of Plants. of the Carboniferous period, though the vegetation would appear to have been poorer in species and more exclusively Lycopodia- ceous ; in which respects it more nearly resembles that of the Lower than of the Middle or Upper Coal-measures. The general history is that of a sea-bottom elevated or filled up in such a manner as to afford sandy or muddy flats, on poi tions of which plants grew, and on other portions vegetable fragments were drifted, or bare surfaces were exposed to the alternate influences of aqueous deposition and aerial desiccation, — these various con- ditions being more or less prevalent throughout a long period, during which the area may have been gradually sinking, to be again disturbed and elevated at the commencement of the Carbo- niferous period. In explanation of the siliceous and plant-bearing character of the Gaspe beds, as compared with their more calcareous and marine character in some other parts of America, I may point to their vicinity to the old Laurentian land on the north side of the Gulf of St. Lawrence, and to the possible existence of a nearer belt of Lower Silurian land, indicated by the unconformability, in this part of Canada, of the Lower and Upper Silurian rocks. In the collection of Sir W. E. Logan there are some vegetable remains from the limestones of Cape Gaspe and its vicinity, which perhaps indicate a still older terrestrial flora than that above de- scribed. They afford, I think, evidence of the existence of at least one species oi Psilophyton and one oi Nceggerathia or Poacites; but whether identical or not with those above described, I cannot determine from the specimens. The beds in which they occur certainly underlie the Gaspe sandstones, and are probably Upper Silurian. ARTICLE II. — List of Plants found growing as indigenous in the neighbourhood of Prescott, C.

This is the Spirorhis sinistrorsa. It is not noted by Fabricius as a Greenland shell, but is found on zoophytes at Gaspe, and abounds on sea weed in deep water off" the coast of Maine. This and the previous species are the only ones that an observer'who confines his attention to the sea weeds of the shore tj (At may chance to meet with; but dredging in deep water will procure the following species. Sp)irorhis nautiloides, the Serjnila spirorhis of Linnaeus, is of the same size with S. Spirillum, but is thicker, less smooth, trans- versely wrinkled, and more flattened at the base, so that when removed from its attachment it appears like a shell split into two equal halves. Its whorls also are more closely united and increase 26 Tuhicolous Marine Worms. in diameter more rapidly, so that there is a deep and narrow umbilical cavity in the centre. It is found both on stones and sea weeds in deep water. This is at least what I take to be the true Seiyula spirorUs of Linnae us and Fabricius, though more recently some confusion between this shell and S, spirillum seems to have arisen. It was found by Fabricius in Greenland. I have it in a collection made in Labrador by Mr. Carpenter, missionary of the Canada Foreign Missionary Society, and Dr. Gould has ob- tained it on the American coast. I have it also on stones from the Banks of Newfoundland. When old, this shell forms a few semi-erect turns, so as to cover up the previous whorls and the umbilicus, and terminates in a thick and slightly expanded mouth, sometimes as much as half a line in width. So completely does the shell in this condition differ from its immature state, that but for the appearances seen in sliced or broken specimens, I should have regarded it as a distinct species. A change of a somewhat similar character, though less marked, occurs in S. cancellata, and is represented in the figure of that species given below. Similar changes, though with diflferences in details, occur in S. vitrea and S, por recta. Spirorhis carinata (Mont.) is a deep water species, closely allied to >S^. nautiloides, if not a variety of it. It is distinguished by a keel or ridge running along the whorls, nearer the inner than the outer edge. In some old shells a second ridge appears, and then the shell very closely resembles S. quadrangularis of Stimp- son. Young shells, on the other hand, are not distinguishable from those of the S. nautiloides. This species is not noted by Fabricius as a Greenland shell. It abounds in the collections of Mr. Bell of the Geological Survey, and in my own from Gaspe, where it occurred in deep water, attached to dead shells and stones. It was found at Labrador by Mr. Carpenter. I also have it on a stone taken up from the Banks of Newfoundland by a fishei man's hook, and presented to me by A. Dickson, Esq. Sp>irorhis vitrea is like S. sinistrorsa^ a reversed species, but is thick, semi-transparent, and has the whorls closely crowded, and in adult shells turned up and somewhat narrowed and thickened at the mouth. A group of these shells looks like a number of small drops of glass that had fallen on a stone and cooled there. Fabricius discovered this species in Greenland. It occurs in Mr. Bell's Gaspd collection, on the Banks of Newfoundland, and fossil Tubicolom Marine Worms. 21 in the Pleistocene beds at Montreal and Beauport. It is noted bj Stimpson as found in the Bay of Fundy. a. G Fig. 1. — Spirorhis cancellata. a nat. size ; b magnified ; c older shell less magnified ; d, e side views. Spirorhis cancellata is in point of ornament the prince of our Spirorbes. It is thick, regularly spiral when young, but with the mouth tending upward when old. Above, it has two, or, in old shells, three strong ridges revolving with the whorls, and giving it an elegant fluted appearance, and the outer side presents a furrow crossed by strong transverse bars, or in other shells appears as a regular slope wilh a series of depressed spaces at regular intervals. The whole appearance of this shell in a perfect specimen is very elegant, and as I have not been able to find a good figure of it in any work that I have consulted, I have attempted to represent it in the figures on this page. It is a reversed species. S. cancellata abounds in Mr. Bell's Gasp^ collection. It is one of the species found by Fabricius in Greenland and named by him, but I am not aware that it has been met with since, until dredged by Mr. Bell in about 60 fathoms on the Gaspe coast, where it lives attached to the valves of dead shells. It is also in Mr. Carpen- ter's collection from Labrador. Sinrorhis granulata^ (Muller) resembles that last described, but wants the ornament around the margin, having only two furrow and three sharp elevated ridges on the upper side, and it is not reversed. Fabricius, who found it in Greenland, states that its animal is yellow, with a white stopper on a short stalk, and sis respiratory filaments. It occurs, though rarely, in Mr. Carpenter's 28 Tubicolous Marine Worms, collection from Labrador, on stones and bryozoa, and was found by Stimpson at Grand Manan. Spirorbis porrecta differs from the others in having only a few spiral turns and then boldly standing erect. It is thin, shining? and round in its tube, and from its habit of growth resembles a serpula ; but the animal is that of a spirorbis. Fabricius very clearly describes it as follows. It occupies when contracted only a third part of the length of the shell, is smooth, flattened on the abdomen and attenuated posteriorly. Its stopper is extended on a stem and at its base are six soft, short, white, conical respiratory processes. At the base of these the body is white, plicated, and armed with golden setae or bristles, extending forward. The rest of the body is blood red above, lighter on the sides and below, and its colour can be seen through the semi-transparent shell. This species occurs at Gaspe on Zoophytes, and is recorded by Stimp- son as found at Grand Manan. It thus appears that of these curious little spiral worm shells, the precise use of which in nature it would perhaps be difficult to point out, but which no doubt enjoy life after their fashion, and afford food to other animals, we have no less than seven or eight species in the gulf of St. Lawrence. Fig. 2. — Serpula (Vermilia) serrula? a nat. size; b anterior part magnified ; c aperture magnified. Genus Serpula. The true serpulse are neither abundant nor large in the Gulf of St. Lawrence, in so far as my observation extends. The most common species, found both in Labrador and Gasp^, is of small size, about ^%th of an inch in diameter, wrinkled transversely and with a distinct and strongly denticulate keel on the back. It is adherent in its whole length, sometimes much and irregularly Tuhicoloiis Marine Worms, 29 bent, sometimes nearly straight. It corresponds exactly with the description of >S^. (Vermilia') serrula of Stimpson, from the Bay of Fundy. It also corresponds with the S. triquetra of Linnaeus and Fabricius, except in its smaller size, and more delicate structure. In some specimens there is a structure which, so far as I am aware, has not been noticed in either of the above species. It consists of two lateral lobes, somewhat more than one-twentieth of an inch in length, attached to the sides of the anterior portion of the tube, and opening by narrow labiate mouths on each side of the princijDal orifice, so that there ap- pear to be three orifices close together, the central one round, the lateral ones narrow and lunate. If the animal inhabiting this shell has the structure of protula, one may suppose that these lobes accommodate the lateral disk or expansion of the thorax. As they appear only in certain specimens, they may perhaps be connected with the function of reproduction, and be of the nature of ovi-capsules, or they may serve to enable a certain amount of respiration to proceed when the gills are retracted. It would be interesting to study the living animal with reference to these curious additions to its tube. Serpula vermicularis is one of the shells which I have described in a former paper as found in the Pleistocene clay at Logan's Farm, but I have not seen it from the Gulf, nor is it noted by Fabricius. It is round, smooth, and tortuous. Genus Pectinaria. A shell, probably of this genus, made up of a single layer of grains of sand, is frequent on sandy shores. It is perhaps P. Groenlandica Grube, P. Belgica Lam., but I have not seen the animal. The Serpula seminulum of Fabricius is a foraminiferous shelly the 31iUolina seminulum described in my previous papers on the Pleistocene deposits. The S. stellaris of Fabricius is the Truncatulina lohaia, also a foraminiferous shell, parasitic on shells and zoophytes, found in the Gulf of St. Lawrence and in the Pleistocene beds. Serpula contortuplicata^ a common Atlantic species, is also noted by Fabricius, but has not been found in the Gulf. This industrious observer has also, under the genera Sahellaj Nereis^ and Tuhularia, several species of tube-dwelling worms^ which are perhaps identical with species of Sahella^ Amp)hitrite^ &c., described by the naturalists of the "^"^nited States, but which have not been observed in the Gulf of St. Lawrence. o List oj tJ.e St, Lawrence Algce. The investigations recorded in the foregoing pages originated partly in the researches necessary to the study of the Pleistocene fossils of the St. Lawrence valley, and partly in the interest of the collections placed in the hands of the author by Mr. Bell and Mr. Carpenter. The most useful guide to the study of these collec- tions has proved to be the old work of Otho Fabricius — the Fauna Groenlandica, a wonderful monument of painstaking and accurate research, to which I hope ere long to direct the attention of Canadian naturalists in a comparative sketch of the marine fauna of Greenland, as described by Fabricius and others, and that of the Gulf of St. Lawrence and the tertiary beds on its margin. For access to this and some other scarce books, and for aid in the comparison of some doubtful species, I have to thank Dr. Gould of Boston and Mr. Stimpson. ARTICLE lY. — A Classified List of 3Iarine AlgcE from the Lower St. Lawrence^ with an Litroduction for Amateur Collectors. By the Be v. Alex. F. Ke3ip. This large and beautiful collection of Algte, which we have here catalogued according to the most recent order of classi- fication, has been put into our hands, for the most part, by a dili- gent and skillful collector (whose name we are not permitted to give), for the purpose of illustrating an interesting department of our Canadian Botany. The Lower St. Lawrence is, we believe, a field for research which has not yet been sufficiently explored. It has all the characteristics to render it the favorite habitat of a very wide range of genera and species. In the colder waters of the north shore, we may expect to find plants peculiar to the Arctic and Sub-Arctic zones, together with those that belong to the temperate shores of the world. Again, the somewhat warmer waters of the southern coast, as far east as Gasp^, with their peculiar shores and bays, will undoubtedly aff'ord forms and species of marine plants, whose limits of geographical distribution reach far into the warmer regions of the south. Further, the junction of the fresh waters of the river with the salt waters of the gulf, will be found a favorite resort for some of the more beautiful and deli- cate species of Algae. We have as yet seen no specimens from this middle region of our waters ; but we have no doubt that somewhere about Grosse Isle, or on the shores of the counties L'Islet and Saguenay, a fine and as yet unexplored field lies open to some enthusiastic collector. List of the St. Lawrence AIg(B. 31. An idea is we fear somewliat prevalent that the collection and classification of sea-weeds is an employment only for children and idle people — that to give anything like earnest attention to this beautiful but comparatively useless class of plants, is to mis-spend one's valuable time. Now, we do not deny that this class of plantsj from their rare beauty of form and colour and from the facility with which they may be prepared as articles of ornament, has become of late years a favourite source of amusement to young persons, and especially to young ladies. It is, however, certain that while they find amusement in collecting and preparing speci- mens, they also bring their minds into contact, in a most instruc- tive way, with some of the most interesting and beautiful forms of Creative Wisdom. They, for example, become familiar with colours of gem-like lustre and with varieties of form and structure, which, for delicacy and beauty, far surpass the conceptions of human imagination or the skill of human hands. Especially this is the case if collectors examine and classify their specimens by the aid of a microscope, with powers ranging from 100 to 400 diame- ters. This will open up to them a world of wonders, and impart a deep and delicious pleasure to all their researches. Now that good microscopes are so cheap and so easily attainable, every collector of plants should have one, and should make it his constant com- panion. There is a large number of the Algae, and these too the most beautiful and interesting, which can only be determined by a, microscopic examination of their tissues and their modes of reproduction. Let not any one imagine that these plants are of no use. They may, it is true, be of little use to us ; but it is taking a low view of the utility of things to judge of it simply by our personal advantage. It is admitted that we can get very little to eat or to sell from the Algae. We would not advise any one to attempt to make a living by collecting and preparing specimens. They are, nevertheless, not without their use. We get iodine, one of the most valuable of medicines, from the Fucaceae ; and the vast quantities of sea-weeds which are cast upon our shores are used extensively as a most excellent manure for our fields. If we judge of the use of the Algae, not by the direct benefits which we receive from them, but from the place which they occupy? and the work wliich they perform in the grand system of the organic kingdom, we shall see that these humble plants are entitled to most honorable consideration. If antiquity is any honor in 32 List of the Si, Lawrence AlgcB, these days, the Algas may say to their more lordly brethren of the woods and gardens, " Our forefathers lived many ages before the first of your tribe was born. We inhabited the shallow waters and the shores of the most ancient Silurian seas, and, in every subse- quent age, for millions of years, we have borne silent testimony to the wisdom of the great Creator." Consider too, that if sea-weeds cannot to any great extent be eaten by us, that yet the tiny molluscs, the radiates and the smaller vertebrate fishes need food as well as we. These plants are the sources from which very many of them are sustained in life. Without them there would be famine in many families of the animal kingdom. The marine plants perform, besides, the same sanitary work in the sea which the land plants perform on the land. Both are most important agents in purifying the atmosphere and preserving it in a healthy state for animal use. These apparently insignifi- cant Alg^e are indeed most busy and benevolent creatures. They swallow up much that is poisonous in the water, and labour hard to keep it pure and sweet. It is well known that the carbon arising from decaying vegetable or animal substances in water or on land, by combining with oxygen, forms carbonic acid gas, which is both very disagreeable to the organs of smell and very injurious to health. Were it not then for the provision which the good Creator has made, by means of land and sea-plants, to counteract this noxious vapour, many parts of the sea and land would be entirely unfit for the residence of animals. These marine plants have the pe- culiar faculty of absorbing from the carbonic acid gas all the noxious carbon, and setting free the healthy oxygen. They thus decompose that injurious compound, and render the waters suita- ble for animal life. In proof of this, we would adduce the fact, which those who are familiar with the sea-shore may have observed, that the Algae are constantly covered with globules of air, which, like studs of brilliants, sparkle with great beauty, and sometimes shine like stars. These globules are the emancipated portions of oxygen, which, having been attracted into the bad society of carbon, are now set free by the benevolent action of the weeds ; the result is, that, grateful for their liberty, they shine with evident joy. We have said enough to show that the lowly Algge are not so useless a class of plants as some people suppose, but that they fill an important place in the grand circle of creation ; they, too, are evidences of that Divine wisdom which it is one of the employ- ments of intelligent and good people to enquire into and admire. To List of the St. Lawrence AlgcB, 33 know their character and habits is to know the wisdom and good- ness of our Father in Heaven. Many young collectors, and admirers of these plants more mature in y^ars, wish to obtain a more full acquaintance with them than that which their own unaided observations afford ; but they are often at a loss to find out how this may be accomplished. Very few people in this country know anything about the scientific structure and classification of the x^lgae. It is, therefore, a rare thing to find a personal instructor and guide. The next best thing is to pro- cure good books ; but then, where shall we find them ? and what do they cost ? are questions frequently put. For the benefit of those who desire to cultivate, in a scientific way, this interesting department of botany, we beg to say that the books which will be of most service to them are neither difficult to obtain nor yet very costly. The best book for this country is a work by Dr. Harvey, of Dublin, recently published by the Smithsonian Institution of Washington. It can be had through any bookseller from the Messrs. Appleton, of New York, at the cost of $6. It is a large quarto size. The plates are most beautiful, and the classification most recent and complete. For a book of its kind it is remarkably cheap. It is entitled ''^ Nereis Boreali-Ameri- cana," The next best book is Harvey's "Atlas of British Sea- Weeds,^' with the little book which accompanies it. This work contains figures of almost every species found in the British waters, and comprises a great part of our American plants. Its cost is three guineas sterling in England, and though somewhat expensive, is really a most delightful and valuable book. " Jlar- vefs Manual of British Marine AlgcB " is a less costly book and one better adapted for beginners, the last edition of which can be procured for about four dollars. A smaller and more ele- mentary work, entitled "Landshorough's Marine Algcje^'' very o-ood and useful for beginners, may be obtained by any bookseller in this country, from Routledge the publisher, at a cost of two dollars. There are other books of a more expensive kind, which mio-ht be named ; but these will enable any one to prosecute, with pleasure and profit, the study of the genera and species of the laro-e sub- kingdom of the Marine Algse. The writer of this article will gladly determine any specimens for young collectors that they may find difficult or obscure. He will also be glad to receive for publication, in the Naturalist any Can. Nat. 3 Vol. V.

ARTICLE V. — Unusual modes of Gestation in Batradiians and Fishes. [Prof. Wyman of Harvard has lately returned from an excur- sion across North America, in the course of which he has collected many curious facts in natural history ; among others, the follow- ing, which we extract from a communication to the Boston Society of Natural History.] " Among Batrachians the circumstances under which the young are developed, though less varied than in some of the other classes of vertebrates, still present a considerable range. By most species the eggs are deposited in the water either upon aquatic plants or on the bottoms ; by others, as in Salamandra eri/thronota, they are laid in damp places under logs or stones ; with some the evolution of the embryo commences a short time previous to the laying of the egg and is completed subsequently, while there are species which are wholly viviparous. "The most remarkable deviations from the ordinary modes are to be found in those instances in which the eggs, after being laid,, are ajrain brouo^ht into a more or less intimate relation with the parent, as in the "Swamp toads " (^Pipa Americana^ of Guiana, where each ovum is developed in a sac by itself on the back of the female, in Notoddphys of Venezuela, where all the eggs are lodged in one large sac, also on the back, and is analogous to the pouch of the Marsupials, and in Alytes, the " Obstetric toad " of Europe, where the eggs are wound in strings around the legs of the male, who takes care of them until they hatch. • " The species, the habits of which are noticed below, and which, in so far as I have been able to learn, have not attracted the attention of naturalists, adds another to the series just mentioned, Gestation in Batrachians and Fishes, 43 though the relation of the foetus to the parent becomes less inti- mate than in any of the preceding cases. ^'' Hylodes lineaius (Dum. and Bib.) is vejy common in Dutch Guiana, and its peculiar habits are well known to the colonists. The first specimen with young which came to my notice had been preserved in alcohol, and was presented to me by Mr. G. O. Wacker, residing at Osembo, on the Para Creek, Surinam, and had been captured at some distance from the water. The young, ten or twelve in number, though separated from the parent, he assured me, when found, were attached to the back. "In the month of May, 1857, during an excursion to the coun-^ try inhabited by the Bush negroes, above Sara Creek on the upper Surinam River, I had an opportunity for the first time of seeing these animals carrying their young. The grass and bushes were quite wet from a recent fall of rain, and this seemed the induce- ment that led them from their hiding places, for when the ground was dry none had been seen. They were very quick in their movements, and when alarmed went at once into the grass and thick bushes. One of my companions, Mr. John Green, and myself succeeded in capturing some specimens, which, as we were just leaving the village, were placed at once in alcohol. In one instance the larvae were retained permanently adherent to the back of the parent, in consequence of the coagulation of the mucus covering the surface of the body, and are still preserved in the Museum of Comparative Anatomy at Cambridge. The young, from twelve to twenty in number, were collected upon the back of the mother, their heads directed towards the middle line. They were about three-fourths of an inch in length. No limbs were developed, though in some of them the rudiments of a leg existed in the form of a small papilla on either side of the base of the tail. No especial organ was found to aid them in adhering to the back of the parent. The adhesion may have been effected by the mouth. This is rendered probable by the fact that all of them had the mouth in contact either with the skin of the parent or with that of another larva. A. viscid mucus covering the integuments un- doubtedly assisted in some measure to bring about the same re- sults. However this may be, they retained their places perfectly well, and were not displaced when their mother, closely pursued, carried them through the grass. " On dissection of the young nothing was found materially dif- ferent to conditions of the larvae of other Anoura. The external 44 Unusual Modes of gills had disappeared, but were replaced by internal ones, which were arranged as. usual on three hyoid arches. The development of the lungs had commenced, and these were represented by a slender conical mass of cells, but not permeable to air. The mouth was provided with finely denticulated horny jaws, and the intestinal canal was shorter and less spirally convoluted than in ordinary larvae of frogs and toads. The stomach was not so much developed as to be distinguished from the rest of the intestine ; but this last, after passing the liver, was somewhat dilated, and contained, as was shown by the microscope, large quantities of yolk cells which had not been absorbed and which were adherent to its walls. We have here then a larva, in all of the details of its structure, especially in the existence of gills and o f a flattened tail, adapted to aquatic locomotion and respiration, yet passing a portion of its time at least on the back of its parent and at a distance from the water. I was not able to ascertain whether the eggs were primarily de- posited in the water or not, but it is well known to some of the colonists that after the larvae have reached a certain degree of de- velopment they are carried about in the manner just described and they do not know them under any other circumstances. The existence of yolk cells in the intestine, shows that for a period at least they may have from these a supply of nutriment. Bat after this is exhausted, and it appeared to be nearly so in those which I have dissected, how do tbey obtain their food ? In the absence of limbs adapted to terrestrial locomotion can they leave the body of the parent ? and if they cannot, do they, as in the case of Pipa and probably in Notodelphys, depend upon a secretion from her ? Among Fishes, as far as at present known, the external condi- tions under which the eggs are developed are more varied than in any other class of Vertebrates. There are scarce any known conditions of the higher classes to which there are not analogies at least in the class of fishes. Besides the ordinary mode of de- positing eggs upon the bottoms, some of the Salmonidse, like the turtles, bury their eggs, the Lampreys (Petromxjzon)^ the Breams, (Fomotis), the Hassars (Callicthys), the Stickle-backs, [Gaster- ostei), &c., build more or less complete nests. Among some of the Pipe Fishes, (Syngnathidce), the eggs and subsequently the young, are carried in a pouch analogous to that of the opossums and other marsupial animals, and among some of the Sharks Gestation in Batrachians and Fishes, 45 there is a vitelline placenta analogous to the Allantoidian one of the Mammalia.* To those species enumerated above where the eggs become more or less intimately connected with the body of the parent after they are laid may be added the Aspredos and some species of Bagrus, from Guiana. Aspredo Icevis (Cuv. and Val.), the "Trompetti" of the colonists, is about fifteen inches in length, and belongs to a remarkable ge- nus of Siluroid fishes, which, in addition to several peculiarities of anatomical structure, are remarkable for carrying the eggs and young attached to the under surface of the body. These fishes are very abundant in the waters of the Surinam where they are taken in the nets with other kinds. They are not used as articles of food except by the negroes, who have a fancy for Siluroids generally, and in consequence these are known among the colo- nists as Ningrefisi or "nigger fish." A general account of the internal structure of Aspredo, is given in the Hist. Nat. des Pois- sons, by Cuvier and Valenciennes, t. xv, p. 35. In the month of June the eggs are found adhering to the un- derside of the body, to the ventral and pectoral fins, and extend as far forward as the under lip, and as far backwards as the mid- dle of the tail. In some however the distribution is much more limited. I was unable to learn anything with regard to the transfer of the ova from the genital orifice to the point of their attachment. The only organ which seems in any way adapted to such a purpose is the slender and flexible tail terminated by a delicate caudal fin. It is possible that the eggs may be deposited on the bottom of the river, and subsequently attached by pressing the underside of the body upon them. In those individuals where the ova were still in the ovary, but approaching maturity, the integuments of the underside of the * Prof. Owen (in Philos. Transactions, 1834,) has pointed out the vas- cular relations of the foetal Kangaroo to the parent. The chorion is not rascular, but the umbilical vesicle is largely provided with blood ves- sels, and, as far as his investigations go, affords the principal vascular surface by means of which an interchange takes place between the foetus and the parent. The vitelline circulation then, as in sharks, is the res- piratory circulation. The allantois of the Marsupials appears to remain in a rudimentary condition, and does not form a connection with the parent. Thus the vascular relation of the foetus of some of the sharks, as Carcharias, with the parent is identical with that of the Marsupials. 46 Unusual Modes of body gave no other indications of the changes about to take place than of being quite vascular ; the skin was perfectly smooth, no " pores " were visible, but a large vessel w^as seen emerging from the region of the liver, and descending along the median line gave oflf branches quite freely to the integuments. This may have some relation to the future development of the pedicles which support the eggs and perhaps to the nutrition ot the embryo as will be adverted to hereafter. In all the specimens which I have had an opportunity of exa- mining, the eggs were either somewhat advanced or quite mature ; so that no observations could be made on the earlier conditions of the Qgg and the formation of its pedicle. The pedicle is a flex- ible outgrowth from the common integuments, is about two lines in length, is attached to the skin by a slightly expanded base, and spreads out at its summit into a shallow cup or " cupule," for the support of the Qgg* It is composed almost entirely of fibrous tissue, invested with a layer of tesselated epithelium. In some instances when the eggs were but little advanced, numerous fusi- form cells were detected among the fibres. It is vascular, two or three vessels reaching to the cup, where they ramify and form a somewhat extended capillary plexus. The eggs vary according to the degree of development from the 0.09 to 0.15 of an inch in diameter, and are covered with an external homogeneous membrane, containing minute punctiform depressions — within this is a second, of a brownish color and com- posed of epithelium. The embryos which were the most advanced and just ready to hatch, had not as yet completely absorbed the yolk, and were coiled up within the membranes, which in conse- quence of the irregularities of the mass formed by the embryo, had no longer a spherical form. The eggs are retained in connection with the cup apparently by adhesion alone, for as soon as the foetus escapes, the Qgg mem- branes become very easily detached from the pedicle, and this last as shown by some of the specimens undergoes absorption. The relation of the embryo to the parent in this singular mode of gestation cannot be determined very accurately, but the vascu- lar plexus in the cup, seems to be more than is necessary for the mere nutrition of the part. The Qgg increases in size during incu- bation, those ova in which the development had but slightly ad- vanced measuring from 0.09 to 0.11 of an inch in diameter, while those nearly mature measured from 0.14 to 0.16 of an inch. Gestation in Batracaians and Fishes. 47 How this increase of size of the embryo over the original size of the egg is actually obtained I have no facts to show^, but either of two suppositions are probable ; it may be by absorption of mate- rials from the water which surrounds it, or from the capillary plexus of the pedicles, and in this case in a manner analogous to that of Pipa. Among the Siluroid fishes of Guiana there are several species, which at certain seasons of the year have their mouths and branch- ial cavities filled either with eggs or young, and as is believed for the purpose of incubation. My attention was first called to this singular habit by the late Dr. Francis W. Cragin, formerly U. S. Consul at Paramaribo, Surinam. In a letter dated August 1854, he says, " the eggs you will receive are from another fish. The different fishermen have repeatedly assured me, that these eggs in their nearly mature state are carried in the mouths of the pa- rent, till the young are relieved by the bursting of the sac. Do you either know or believe this to be so, and if possible, where are the eggs conceived and how do they get into the mouth ?" In the month of April, 185*7, on visiting the market of Para- maribo, I found that this statement, which at first seemed to be very improbable, was correct as to the existence of eggs in the mouths of several species of fish. In a tray of fish which a negro woman ofiered for sale, I found the mouths of several filled with either eggs or young, and subsequently an abundance of opportu- nities occurred for repeating the observation. The kinds most commonly known to the colonists, especially to the negroes, are Jara-hakJca^ Njinge-njinge^ Koepira^ Makrede and one or two others, all belonging either to the genus Bagrus or one nearly allied to it. The first two are quite common in the market and I have seen many specimens of them ; for the last two I have the authorithy of negro fishermen but have never seen them myself. The eggs in my collection are of three diff"erent sizes, indicating so many species ; one of the three having been brought to me without the fish from which they were taken. The eggs become quite large before they leave the ovaries, and -are arranged in three zones corresponding to three successive broods, and probably to be discharged in three successive years ; the mature eggs of a Jara-bakka eighteen inches long, measure three-fourths of an inch in diameter, those of the second zone one fourth ; and those of the third or very minute, about one sixteenth of an inch. 48 Unusual Modes of A careful examination of eiglit specimens of Njinge-njinge about nine inches long, gave the following results: The eo'ors in all instances were carried in the mouths of the males. This protection, or gestation of the eggs by the males, corresponds wnth what has been lona^ noticed with reo;ard to other fishes, as for example, Syngnathus where the marsupial pouch for the eggs or young is found in the males only, and Gasterosteus where the male constructs the nest and protects the eggs during incubation, from the voracity of the females. In some individuals the eggs had been recently laid, in others they were hatched, and the foetus had grown at the expense of some other food than that derived from the yolk, as this last was Dot proportionally diminished in size, and the foetus weighed more than the undeveloped egg. The number of eggs contained in the mouth was between twenty and thirty. The mouth and branchial cavities were very much distended, rounding out and distorting the whole hyoid and branchiostegal region. Some of the eggs even partially protruded from the mouth. The ova were not bruised or torn as if they had been bitten, or forcibly held by the teeth. In many instances the foetuses were still alive, though the parent had been dead for many hours. No young or eggs were found in the stomach, although the mouth was crammed to its fullest capacity. The above observations apply to Njinge-njinge. With regard to Jarra-bakka, I had but few opportunities for dissection, but in several instances the same conditions of the e^^s, were noticed as stated above ; and in one instance, besides some nearly mature foetuses contained in the mouth, two or three were squeezed ap- parently from the stomach; but not bearing any marks of violence or of the action of the gastric fluid. It is probable that these found their way into that last cavity after death, in consequence of the relaxation of the sphincter which separates the cavities of the mouth and the stomach. These facts lead to a conclusion that this is a mouth gestation, as the eggs are found there in all stages of development, and even for some time after they are hatched. The question will be very naturally asked, how under such cir- cumstances, these fishes are able to secure and swallow their food. I have made no observations bearing upon such a question. Unless the food consists of very minute particles, it would seem necessary that during the time of feeding the eggs should be dis- gorged. If this supposition be correct, it would give a very pro- Gestation in Batrachians and Fishes, 49 bable explanation of the only fact which might be considered at variance with the conclusion stated above, viz., that we have in these fishes a mouth gestation. In the ma?s of eggs with which the mouth is filled, I have occasionally found the eggs, rarely more than one or two, of another species. The only way in which their presence may be accounted for, it seems to me, is by the supposition that while feeding, the eggs are disgorged, and as these fishes are gregarious in their habits, when the ova are re- covered, the stray egg of another species may be introduced into the mouth among those which naturally belong there. ARTICLE VI. — Description of some new species of Fossils from the Lower and Middle Silurian Rocks of Canada. By E. Billino^s. (From the Report of the Geological Survey for 1860.) In the Silurian Rocks of Canada and the neighbouring coun- tries there are maiiy species or varieties of that group of the genus Strophomena of which S. alternata may be regarded as the typical form. These are all closely related and yet exhi- bit such differences that only those naturalists who entertain wide views upon the subject of the value and significance of specific distinctions, would feel inclined to unite them under one common name. The forms of this group most common in the Lower and Middle Silurian Rocks are S. alternata^ S, incrassata, S, deltoidea^ S. camerata, S. tenuistriata and some others to be described hereafter in this paper. The first of these ranges from the Chazy limestone upwards perhaps to the Niagara rocks but is most abundant in the Trenton limestone and Hudson River group. It is also very widely distributed, as it occurs in all parts of the Continent, where the last two formations have been recognized and is also found in the Lower Silurian in England and Ireland. S. incrassata has exactly the same form as some of the varieties of aS'. alternata but is never, as far as I have been able to ascertain, more than half the average size of this latter species. It seems to be confined to the Chazy and the Black River limestone or the lower part of the Trenton, and has therefore, a geological distribution diff'erent from that of S. alternata^ a fact which would appear to constitute an additional ground for classi- fying it as a distinct species. S. deltoidea is a Trenton lime- Canadian Nat. 4 Vol. V. No. y 50 Silurian Fossils of Canada, stone form abundant in certain localities, but not generally distributed. Thus in the State of New York, accordino- to Pro- fessor Hall "it abounds at Trenton Falls and at Suo-ar River in Lewis County," but "is scarcely known as occuring in the Chaniplaim valley."* In Canada it is found at Lachine and at several other places, but there are hundreds of good exposures of the rock in the Province that have been carefully examined, where not a single specimen has been seen, although in all the localities ;S^. alternata is more or less common. S. camerata occurs at one spot in the vicinity of Ottawa, but I have never met with it elsewhere. ^S'. ienuistriata may be collected in the hard black limestone around the base of the mountain of Montreal, particularly in the neighbourhood of the McTavish monument and also at Ottawa and two or three other places, but does not occur at all in the majority of the localities of the Trenton lime- stone. These three species, therefore, must have been capable of existing in certain places only, on the bottom of the ocean during the period of the accumulation of this rock, while >S'. alternata^ flourished everywhere. Whether or not, therefore, they are to be regarded as distinct species, this much at least seems prob- able, that they were by some peculiarity in their habits or in their organization, unfitted for so wide a range through the seas as that enjoyed by S. alternata. The question, whether or not these supposed species are really distinct, cannot be answered until naturalists shall have discovered some general law of life by an appeal to which they may in all cases determine what is a species as distinguished from a mere variety. It is scarcely necessary to state that such a law if it do exist at all may remain unknown to man for ages, and in the meantime nearly all determinations of species from varieties where the forms are very closely related may be regarded as not positively established. The physical geologist is more inter- ested in the results of investigations which show that certain forms are confined to particular geological horizons than in those, whose sole object is to determine the exact zoological rela- tions of such forms. If it be true, for instance, that that parti- cular form of the genus called Strophomena incrassata is con- fined to the limestones lying next under the Trenton in the fossil- iferous series, it makes no difference to the geologist, whether it * Palaeontology of New York, vol. 1, page 107. Silurian Fossils of Canada* 51 be in reality a distinct species of itself or only a variety of some other species. Its value to liim as a guide, while tracing out the geographical distribution of these Rocks, is not at all affected by the zoological question. In demonstrating the physical structure of the country, he can reason upon varieties with as much safety as upon true species, provided that such varieties are confined to and consequently characteristic of particular por- tions of the geological edifice. It is therefore, of great impor- tance, not only to ascertain to what particular level each variety is confined, but also to determine whether or not such species as range through several formations exhibit any and what change in form on passing from one group of rocks to another. Should it be hereafter, proved that the supposed species above quoted, constitute on purely zoological grounds, but one extensive and variable species still it would be convenient for geological pur- poses to have a separate name for each variety that can be shewn to be characteristic of a particular geological horizon. Before entering upon the description of the new species, I shall give a general account of such characters as are common to all the forms of the group typified by S. alternata, Strophomena alternata, (Conrad.) In all the forms of this important type, the convexity of the- ventral valve has a peculiar contour which may be seen not only in the Lower Silurian but also in the Upper Silurian and even in such Devonian species as S. Pattersoni, S. inequii-adiataj S. demissa, S. concava and others. That part of the valve which is usually called the visceral disc occupies all the central region of the shell and terminates in a point at the beak. Just in front of the beak it forms a more or less well defined low rounded umbo on each side of which there is a flattened or sub-concave depression extending obliquely outwards to the margin just in front of the cardinal angles. These latter are usually reflected or a little curved upwards from the plane of the lateral margins. The visceral disc is somewhat flattened, gently convex or only slightly elevated throughout the greater part of its extent. In tbe upper half of the shell it is bounded by the depressions that have been mentioned as existing between the umbo and cardinal angles, but in front and at the sides it terminates where the shell 52 Silurian Fossils of Canada* begins to be bent down to form the deflected margin which rims all round the edge and becomes obsolete on approaching the car- dinal angles. This margin varies in width from one-twelfth to two-thirds the whole length of the shell and therefore the disc in some of the varieties occupies nearly the whole superficies of the valve, but in others, less than half. In the very young shells in most of the specimens that I have seen, there is no deflected margin and occasionally adult individuals maybe found, which on a side view give the outline of an uniform flattened arch from beak to front. In by far the greater number of the specimens however the deflected margin is well defined. The contour of the front of the visceral disc varies according to the form of the deflected margin and is thus either broadly rounded or more or less pointed. In S. depressa, which also belongs to this group, the front of the disc, and its sides also, are often nearly straight. The dorsal valve is flat or only gently concave beneath the visceral disc of the ventral valve, but all round, its curvature con- forms to that of the deflected margin. In the t'^ue S. alternata the areas of the ventral and dorsal valves are inclined towards each o her at an angle varying from 75° to 80°, but this angle never amounts to 90°. It will be ob- served that in some of the new species hereinafter described it is greater than 90°. The surface in most of the species exhibits two sets of radiating strise, the larger of which are about one-twelfth of a line wide in large specimens, and the smaller half that size, from one to ten of the smaller between each two of the larger, the more common numbers being from three to five. Sometimes also the shell is marked with a series of concentric wrinkles. Of the above characters, those which are confined to the upper half of the shell such as the form of the beak, the umbo, the concave depressions or hollows on each side of the umbo, and the reflected cardinal extremities, are common to all the species and in order to avoid repetition will not be particularly dwelt upon in the following descriptions. The radiating striae are also very constant in the aspect they present. The only parts which appear to afford permanent variations of much value are the front of the visceral disc the deflected margin and the hinge line. The proportional length and breadth of the shell seems also to be of much importance especially if accompanied by a variation in two or three of the other characters. Silurian Fossils of Canada, 53 Strophomena nitens. N. s. Fig. 1. — Strophomena nitens. a is a section shewing the curvature and obtuse angles formed by the inclination of the areas. Description. — Transversely semi-oval, sides somewhat straight for one third or a little more of the length from the cardinal angles, and slightly converging towards each other; front angles broadly rounded; front margin gently convex or nearly straight for about one third the width in the middle portion. Wid h on hinge-line from nine to twelve lines. Length from six to eight lines. The beak, umbo, depressions on each side of the umbo and the cardinal angles of the ventral valve the same as in S. al- ternata. The deflected margin forms an angle of between 100^ and 110^ with the general plane of the visceral disc, and occu- pies on the median line (in all the specimens I have seen) from one third to nearly one half the whole length of the shell. The dorsal valve is quite flat, or even a little concave, just in front of the beak, but elsewhere curved to correspond with the ventral valve. The area of the ventral valve lies nearly in the plane of the lateral margin^, and the area of the dorsal valve forms with it an angle of about 95^. The height of the area of the ventral valve at the foramen is three fourths of a hne in a specimen nine lines wide, and of the dorsal valve about one third of a line. Foramen of ventral valve partly closed by a V-shaped deltidium, the lower open part of which is closed by the strongly projecting deltidium of the dorsal valve. The width of the foramen is about equal to its height. The surface is the same as in S. alternata, and, when a little worn, presents a smooth shining silken lustre. When compared with S. incrassata, S' alternata, S. deltoidea , S. camerata, or *S^. teniiistriata^ it will be seen that this species is shorter in proportion to the width than any of theni, and also that the inclination of the areas towards each other differs in forming an obtuse instead of an acute angle. 54 Silurian Fossils of Canada, Locality and Formation. — This species occurs at Charleton Point, Anticosti, in the upper part of the Hudson River group. Collector. — J. Richardson. Strophomena Ceres. N. s. Description. — Semi-oval, sides rather straight and a little con- verging for one third their length ; front angles and margins broadly rounded. Width on hinge-line twelve to fifteen lines ; length ten to twelve lines. The ventral valve varies greatly in the amount of its convex- ity. In some specimens it is depressed convex, and these have almost precisely the aspect of the more flattened forms of S. al- ternata. Others are strongly convex, nearly hemispherical, uni- formly arched from beak to front, no deflected margin distinct from the visceral disc, the latter occupying the whole of the shell except a small triangular space at the hinge-angles. Between these two extremes there are individuals which present all the intermediate degrees of convexity, and some in which the deflected margin can be detected with a width equal to half the whole length of the shell. The surface is the same as that of >S^. alternata. The area of the ventral valve is one line high in a specimen fourteen lines wide, and lies very nearly in the plane of the late- ral margin. The foramen is as wide as high, and closed by a strongly convex deltidium, the lower margin of which is concave to admit the equally convex deltidium of the dorsal valve, whose area is almost half a line wide and forms au obtuse angle of between 90^ and 100° with that of the ventral valve. The beak of the ventral valve exhibits in some specimens a small round perforation. This species difl"ers from S. nitens ia being in general a little longer proportionally, larger, and more uniformly convex, with scarcely a distinct deflected margin. In S. nitens the length is in general only two thirds of the width, but in this species it is .-always over five sixths. The angle formed by the inclination of the areas being obtuse instead of acute furnishes the only character as far as I can ascer- tain by which it can be separated from S. alternata.

Description, — Shell rather small and thin, semi-oval, the front and front angles regularly rounded, sometimes a little narrower at the base of the ears than at one third the length from the hinge line, the latter usually exceeding the greatest width of the shell, and forming projecting spiniform ears. Width excluding the ears, five to nine lines ; length five-sixths of the width ; ears one line and a half in length each, in a well preserved specimen five lines wide. The ventral valve is in the small specimens, depressed convex and nearly uniformly arched from beak to front ; the umbo well defined, but the concave depressions on each side rather obscure ; no deflected margin. The large specimens (nine lines wide) are sometimes strongly convex. Dorsal valve concave, its curvature corresponding to that of the ventral valve. Surface as in S. alter- nata. Area of ventral valve half a in line height in a specimen seven lines wide, lying nearly in the plane of the margin, apparently a little sloping outwards, forming an angle of about 100° with that of the dorsal valve, which latter is scarcely one-fourth of a line wide. Foramen not distinctly observed but apparently wider than high. The detached and empty ventral valves exhibit two rather large triangular hinge teeth, one on each side of the foramen, covered with stri£e on the outside in a manner similar to that of the area of those species to which Professor Hall has given the generic name of Strophodonta. The spiniform ears are often either broken or worn away. Varieties. — Several specimens nine lines wide without ears, and others of the same size strongly convex, and with an indis- 56 Silurian Fossils of Ca?iada, tinct deflected margin, occupying from one-third to one-half tlie length of the shell, appear to belong to this species. This species when the ears are broken away has exactly the appearance of S. alternata, only that it is never more than half the size. The characters of the hinge areas and teeth taken together with the small size, and hinge ears are abundantly suffi- cient to show that it is distinct from S. alternata. It is a longer shell than S. nitens^ and is in general destitute of a deflected mar- gin. It is smaller, thinner and less convex than S, Ceres, Locality and Formation. — Anticosti, in strata situated from 800 to 1000 feet above the base of the Middle Silurian, and 250 feet below the rocks containing Pentamerus oblongus.

Description. — Shell rather large ; hinge line exceeding the greatest width, forming short rounded ears ; sides gently convex, converging towards each othier; front margin and angles regu- larly rounded, sometimes with a projecting lobe in the middle. Width on hinge line from eighteen to twenty four lines. Length from two-thirds to four-fifths the width. In the ventral valve the umbo and depressions on each side are well defined and exactly like those of the convex form of S. al- ternaia. The visceral disc is moderately and broadly convex y the deflected margin from one-fourth to one-third the whole length of the shell, passing into the disc with a short rounded curve.

The foramen ap- pears to be almost completely closed, but this character has not been ascertained with certainty owing to the imperfection of the specimens examined. The hinge teeth are striated as in S.Leda, The area of the dorsal valve is almost linear, or at the most not half the width of that of the ventral valve. The surface does not difter from that of S. alternata, so far as I have been able to ascertain. Varieties. — One sj>ecimen has been found associated with the others of this species in which the length and breadth are almost equal. It has no ears, although it is longer in proportion to the ■width, and yet it does not appear to differ sufficiently to constitute a distinct species. Another specinaen has a rounded fold in the front margin which becomes obsolete at one third the length of the shell. This species by its projeciing ears, narrow areas and striated hinge teeth is most closely related to >S^. Leda^ from which it dif- fers in being four times the size. It has so much of the aspect of S. alternata, that at present we have no means of distinguishing it from that species wiihout an examination of the hinge area and teeth. Locality and formation. — Middle Silurian Anticosti, associated ■with Pentamerus ohlongiis. Collector. — J. Richardson. The above four species, S, nitens^ S. Ceres^ S.

The three following have the ventral valve concave, and belong to a very dilferent group, of which S.filitexta (Hall) may be regarded as a typical form. Strophomena fluctuosa. N. s. Description. — Triangular, or semi-oval, usually widest at the hinge-line, and more or less narrowly rounded, pointed, trilobed, or nasute in front. Dorsal valve convex, the visceral disc being in general equal to one third the superfices of the whole valve, nearly flat, the remainder abruptly curved down all round so that the lower half of the length of the shell is sometimes at right angles ■with the upper half. The cardinal angles more or less com- pressed and often a little reflected, usually forming angular or 58 Silurian Fossils of Canada, narrowly rounded ears. Ventral valve concave, the curvature corresponding to that of the dorsal valve. Area of dorsal valve lying in the plane of the lateral margin, about one third of a line high. Area of ventral valve forming a right angle with the marginal plane, in large specimens one line or a little more in height at the beak, and gradually decreasing towards the extremities of the hino-e-line. Foramen of ventral valve triangular ; the width at the base somewhat exceeding the height, completely closed by a convex deltidium, the basal margin of which is rendered a little concave by the convex margin of the similar deltidium which closes the foramen of the dorsal valve.

Surface with a set of fine rounded elevated radiating striae dis- tant from each other usually about half a line, sometimes a little less and occasionally one line. Between each two of these there are from two to ten much finer striae ; the whole crossed by fine crowded concentric lines. In most of the specimens the whole of the upper half of the shell is covered with short undulating wrinkles, which sometimes have a concentric arrangement and often form concentric rows converging from the hinge-line to- wards the centre of the shell, crossing each other. The speci- mens from the Trenton limestone are usually without these undu- lations, but in those from the Hudson River group this character is prominently exhibited. This shell is somewhat variable in its characters. The visceral disc of the dorsal valve is sometimes confined to a small area around and in front of the beak and along the hinge-hne, and in such cases the deflection takes place at one fifth or one fourth the length from the beak. Occasionally a broad rounded elevated Sihirian Fossils of Canada. 59 mesial fold extended into a linguiform projection of the middle of the front margin gives to the dorsal valve a trilobate character. The area of the ventral valve is in general at right angles to the plane of the lateral margins, but sometimes it slopes a little for- ward. In some the hinge-line is greatly extended, the cardinal extremities forming projecting triangular ears. Width on hinge-line from one inch to one inch and a half- Length variable, from two thirds of the width to four fifths or a little more. Stro'phomena deltoidea (Conrad) has the ventral valve convex and may be always distinguished from this even when the hinge" line cannot be seen by the small rounded umbo close to the beak. >S'. camerata and S. tenuistriata (Conrad) have also the ventral valve convex.

Strophomena Thalia. N. s. Description. — Semi-oval or sub- triangular, often narrowly rounded or somewhat pointed in front, hinge-line usually greatly exceeding the width of the shell, and forming with the sides an angle of from YO^ to 80°. Width at hinge-line from one to two inches, length about five eighths the width. Dorsal valve moderately convex, depressed towards the cardi- nal angles, which are a little recurved ; umbo flat. On a side- view the outline forms a gentle and nearly uniform curve from the front for about four fifths the length, when it descends with a flat slope to the beak, which it reaches at an angle of from 459 to 60O. Ventral valve concave, the greatest depth about the middle or a little nearer the beak. Area of ventral valve moderate, forming an angle of about 100^ with the plane of the margin, its height in a specimen two inches wide, one line ; foramen triangular, closed by a convex deltidium, its width at the base about one fifth greater than the height. The beak is not perforated in any specimen that I have seen. Area of dorsal valve nearly in the plane of the margin, its width about one third of that of the ventral valve.

This species is allied to S.fluctuosa, but diff'ers in having the areas of the ventral and dorsal valves inclined, at an angle which is rather less than a right angle. In its outline it forms nearly an uniform arch instead of being abruptly bent like S. fiactuom. The dorsal valve of S. recta (Conrad) is said to have a slight mesial depression, while the ventral valve is flat. >S^. piano-con* vexa (Hall) has also a slight mesial depression in the dorsal valve, and is flat or even a little convex in front of the beak of the ventral valve, where this species is concave. It has also a perforated beak, and an area more approximated to the plane of the lateral margins that it is in S. Thalia. The three species are, however, notwithstanding these difl'erences, closely related. Locality and Formation. — Trenton limestone, City of Ottawa. Collector. — E. Billings. Strophomena Hecuba. N. s.

Width on hinge-line about two inches ; length varying from a little less to a little more than the width. Dorsal valve very convex, nearly regularly arched from beak to front, only a small space at the hinge extremities compressed, the whole of the remainder of the shell exceedingly ventricose, usually a rounded fold in front which becomes obsolete at one fourth the length, area sublinear, scarcely half a line in width in the largest specimens. Silurian Fossils of Canada, 61 Ventral valve depressed convex near the beak, and concave all round near the maro^in, area about one line wide and forming an angle of about 115^ with the plane of the lateral margins. For- amen not observed. Suiface marked with fine radiating striae, ten or twelve in the width of one line, every third, fourth or fifth one of which is twice the size of the intermediate fine ones. The whole surface is besides (in most specimens) ornamented with indistinct con- centric wrinkles from one fourth of a line to two hues in width. There are probably fine concentratic striso, although I have not, (owing to the partially exfoliated state of the specimens examined) been able to detect them. This species varies considerably in the amount of the convexity of the dorsal valve and in the size of the mesial fold in front Some have a wide flat space in the umbonial region, and in such on a side-view, the outline of the shell rises from the beak at an angle of about 45^ onh', while in others, which are more ventri- cose this angle is full 60^ with the plane of the margin. Sometimes the sides are strongly compressed, so that the shell becomes subcylindrical and greatly produced in front, the length, exceeding the width. In some specimens the striae are nearly all of the same size, but in general they alternate as in the finest marked specimens of aS^. alternata. Resembles S.

Length of the two specimens examined Ij inches each, lengih of head 5 lines, of thorax about 8 lines, of pygidium 6^ lines. The head is broadly rounded in front and appears to terminate in short spines at the posterior angles. The glabella is broad in front, narrowed behind and covered with small but prominent rounded tubercles about \ or j\ of a line in diameter and of which there are from 10 to 15 in an area of one line square. The anterior lobe of the glabella is transversely sub-oval and its width about equal to the whole length of the head. It is separated from 62 Silurian Fossils of Canada^ the posterior portion of the glabella by strong deep furrows directed obliquely forward and outward. The distance between the inner extremities of these furrows is about 1^ lines in a speci- men 1 J inches in length. The second and third lobes are united into one large obliquely triangular lobe with a small transverse pit at the inner margin representing the second furrow. The fourth or posterior pair of lobes are obscurely preserved in the specimens, but they appear to be small. The neck furrow seems to be strongly marked quite across the base of the glabella and the neck segment rather prominent. The eyes as partly exhibited in one of the specimens are rather small, their diameter being one line or perhaps rather more. They appear to be distant a little more than their own length from the posterior margin of the head. Fig-. 8. — Dalmanites Behryx. The segments of the thorax are not well preserved in the spe- cimens, but there appear to be eleven. The axis when crushed flat four lines wide at the fifth segment and three lines at the last. The pygidium is triangular ; the middle lobe convex, elongate conical, and with from fifteen to twenty segments becoming gradually more numerous in a given space as they approach the posterior extremity. The side lobes have each about ten pleurss all of which are distinctly grooved along the middle. The pygi- dium appears to terminate in a rounded point a little turned upwards. I have not seen the margin of the pygidium and have not therefore ascertained its characters. From the appearance of the specimens I think it almost certain that the posterior angles of the head are produced into short spines.

Head, excluding the spines, very nearly a perfect semi- circle, ■with a shallow concave marginal groove all round the front and sides, and a strongly defined neck-furrow extending across at less than one line from the posterior margin ; glabella equal to the whole length of the head, moderately convex in front, the anterior lobe transversely oval, twice the width of the neck-segment, not defined at the sides in front, but confluent with the surface of the cheeks. The anterior furrows have their inner extremities separated by a space equal to their own length, extending obliquely out- wards to points situated a little forward of the inner front angles of the eyes. The middle furrows have their outer extremities opposite the mid-length of the eyes and extend inward in a direc- tion gently inclined forward until their inner extremities are a little within one third the width of the glabella at mid-length from each other. The third furrows are opposite the posterior angles of the eyes, parallel or nearly so with the middle pair and about the same length. The neck furrow is well defined quite 64 Silurian Fossils of Canada. across tbe glabella. The sides of the glabella are curved a little inward at the posterior lobes and then outwards to the outer extremities of the anterior furrows. The neck segment is large and has its posterior margin rather stronnjly elevated. The cheeks are moderately tumid. The eyes are semicircular, prominent, one fourth the whole length of the head, about their own length from the posterior and a little more than their length from the anterior margin ; the distance between their centres appears to be aoout one twelfth or one fifteenth greater than the length of the head. The surface of the glabella is ornamented with small rounded tubercles of various sizes, the largest being about one fifth of a line in diameter at the base and, in general, distant once or twice their own width from each other. Surface of cheeks not yet distinctly observed but appears to be smooth. In none of the specimens are the lenses of the eyes preserved. Thorax with eleven segments; axis well defined and appa- rently as wide as the side lobes, but this character cannot be suffi- ciently determined, as all the specimens are crushed. Length of the thorax once and a half the length of the head. The pygidium in the only specimen that I have seen in which any considerable portion of it remains attached to the body, has the posterior extremity broken away. Judging however from the curves of the posterior margin I think it probable that there is no terminal spine as there is in most of the species of this genus. There are about ten segments in the axis and apparently ten in the side lobes. If the pygidium have no terminal spine the proportional lengths of the specimen figured would be very nearly as follows : Head, ...... 5 lines. Thorax, .... TJ lines. Pygidium,. . . 5 lines.

Head somewhat semicircular or sub-crescentiform, the front con- vex and the posterior margin concave, the angles rather pointed but not produced into spines. Glabella moderately tumid, de- pressed convex on the top abruptly descending to the front margin, separated from the eyes by a narrow deep furrow, the anterior angles spreading out and becoming obsolete in front of the centres of the eves, an indistinct maro-jnal o-roove round the front which does not extend to the cheeks beyond the anterior angles of the glabella. The neck segment is strongly elevated, connected with the main body of the glabella by a narrow convex neck-like rido-e with a small rounded tubercle on each side. All of the glabellar furrows are but slightly impressed ; the two anterior are situated close to the inner front angles of the eyes, their direction forming with the longitudinal axis of the body an angle of 45° ; they slope forward and outward and are short, a little curved and so faintly impressed that they can be seen on very perfect speci- mens only. The middle furrows lie in a line drawn across the head cutting the eyes at points a little less than one fourth of their length from their front angles; in some specimens these two furrows appear to be straight but in others a little curved the Convex side towards the front. The posterior furrows lie a little behind a line drawn throuo-h the centres of the eves. The sides of the glabella are straight or nearly fo from the tv/o neck tubercles to the inner front angles of the eyes when they curve a little outwards and become obsolete on approaching the ill-defined anterior angles (of the glabella) which are situated midway be- tween the eyes and the anterior margin. The eyes are very large, sub-semicircular, the lens-bearing sur- face not vertical but above sloping a little inwards, more elevated at the anterior than at the posterior extremity ; lenses about seventy five arranged in vertical rows in general five in each row.

The fulcrum or bend of the pleurae is distant from the axis about one half the width of latter. The pygidium is broadly rounded behind with six or seven ribs on the prominent conical axis and four or five broad flat indistinct ones each divided a'ong tlie middle in the lateral lobes. The ribs on the axis become more and more indistinct back- wards and those on the sides extend scarcely two thirds from it thus leavinsf a broad smooth maroin all round. The posterior extremity of the axis is not well preseryed in any of the specimens that I have seen and I have not therefore ascer- tained whether or not it is well defined or confluent with the gene- ral surface. The surface appears to be smooth but as the best specimens seem to have been a little worn it may be that the glabella is tubercular.

In each groove there are two rows of small and apparently nearly square ambulacral plates, twelve or fourteen in each row, and they seem to be con- tinued round on the inner margin of the oral plates ; the mouth is about one line wide. This species differs from P. Niagarensis, (Hall), (Pal. N. Y., Vol. 2, page 24Y, pi. 51, figs. 21, 22, 23,) in being smaller, the rays not so slender, and more importantly in the junction of the adambulacral plates outside of the oral plates. In the 3rd Decade of the Geological Survey I have defined the genus Stenaster as difi'ering from Paheaster, by the possession of 70 Antiqidty of the Human Race, ten oral plates instead of five. The discovery of a second species with only five oral plates confirms the opinion there expressed that Palceasteris a genus quite distinct from Stenaster. For the privilege of describing this highly interesting fossil I am indebted to Dr. J. W. Dawson, LL.D., to whose cabinet it be- longs. It was found by the Rev. D. Honeyman, at Arisaig, in Nova Scotia.

President. — Sir Charles Lyell, L. L. D. ; D. C. L. ; F. R. S. The Prince Consort having entered the Section Room, Sir C. Lyell spoke as follows : — ANTIQUITY OF THE HUMAN RACE. No subject has lately exited more curiosity and general interest among geologists and the public than the question of the antiquity of the human race ; whether or no we have sufficient evidence to prove the former co-existence of Man with certain extinct mam- malia in caves or in the superficial deposits commonly called drift or " diluvium." For the last quarter of a century, the occasional occurence in various parts of Europe, of the bones of man or the works of his hands, in cave-breccias and stalactites associated with the remains of the extinct hygena, hear, elephant, or rhinoceros, have given rise to a suspicion that the date of man must be carried further back than we had heretofore imagined. On the other hand^ extreme reluctance was naturally felt on the part of scientific rea- soners, to admit the validity of such evidence, seeing that so many caves have been inhabited by a succession of tenants, and have been selected by man, as a place not only of domicile, but of sepulture, ^±ntiquity of the Human Race. 71 while some caves have also served as the channels through which the waters of flooded rivers have flowed, so that the remains of living beings which have peopled the district at more than one era may have subsequently been mingled in such caverns and confound- ed together in one and the same deposit. The facts, however recently brought to light during the systematic investigation, as reported on by Falconer, of the Brixham Cave, must, I think, have prepared you to admit that scepticism in regard to the cave, evidence in :^xvor of the antiquity of man had previously been pushed to an extreme. To escape from what I now consider was a legitimate deduction from the facts already accumulated, we were obliged to resort to hypotheses requiring great changes in the rela_ tive levels and drainage of valle3'S, and, in short, the whole physi_ cal geography of the respective regions where the caves are situated — changes that would alone imply a remote antiquity for the human fossil remains, and makes it probable that man was old enouo;h to have coexisted, at least, with the Siberian mammoth But, in the course of the last fifteen years, another class of proofg have been advanced, in France, in confirmation of man's antiquity into two of which I have personally examined in the course of the present summer, and to which I shall now briefly advert. First, so long ago as the year 1844, M. Aymard, an eminent palasontolo- gist and antiquary, published an account of the discovery in the volcanic district of Central France, of portions of two human skele- tons (the skulls, teeth, and bones), embedded in a volcanic breccia found in the mountain of Denise, in the environs of Le Puy en Velay, a breccia anterior in date to one at least, of the latest erup- tions of that volcanic mountain. On the opposite side of the same hill, the remains of a large number of mammalia, most of them of extinct species, have been detected in tufaceous strata believed, and, I think, correctly, to be of the same age. The authenticity of the human fossils was from the first disputed by several geologists, but admitted by the majority of those who visited Le Puy and saw, with their own eyes, the original specimen now in the museum of that town. Among others, M. Pictet, so well known to you by his excellent work on palaeontology, declared after his visit to the spot, his adhesion to the opinions previously expressed by Aymard, My friend, Mr. Scrope, in the second edition of his volcanoes of Central France, lately published, also adopted the same conclusion although after accompanying me this year to Le Puy, he has seen reason to modify his views. The result of our joint examination, 72 Antiquity of the Htiman Race* a result which, I believe essentially coincides with that arrived at by M. M. Hebert and Lartet, names well known to Science, who have also this year gone into this enquiry on the spot, may thus be stated. We are by no means prepared to maintain that the specimen in the museum at Le Puy, (which unfortunately was never seen in situ by any scientific observer), is a fabrication. On the contrary we incline to believe that the human fossils in this and some other specimens from the same hill, were really imbedded by natural causes in their present matrix. But the rock in which they are entombed consists of two parts, one of which is a compact^ and for the most part thinly laminated stone, into which none of the human bones penetrate ; the other containing bones, is a lighter, and much more porous stone, without lamination, to which we could find nothing similar in the Mountain of Benise, although both M. Hebert and I, made several excavations on the alleged site of the fossils. M. Hebert therefore su2ro;ested to me that this more porous stone which resembles in colour and mineral compo- sition, though not in structure, parts of the genuine old breccia of Denise, may be made up of the older rock broken up and after- wards re-deposited, or as the French say ' remane,' and therefore of much newer date. — An hypothesis which well deserves conside- ration but I feel that we are at present so ignorant of the precise circumstances and position under which these celebrated human fossils were found, that I ought not to waste time in speculating on their probable mode of interment, but simply declare that in my opinion they afibrd no demonstration of Man having witnessed the last volcanic eruptions of Central France. The skulls, accord- ing to the judgment of the most competent osteologists who have yet seen them, do not seem to depart in a marked manner from the modern European, or Caucasian type, and the human bones are in a fresher state than those of the Elepkas meridionalis and other quadrupeds found in any breccia of Denise which can be referred to the period even of the latest volcanic eruptions. But while I have thus failed to obtain satisfactory evidence in favour of the remote origin assigned to the human fossils of Le Puy, I am fully prepared to corroborate the conclusions which have been recently laid before the Royal Society by Mr Prestwich, in regard to the age of the flint implements associated in undisturbed gravel, in the north of France, with the bones of Elephants, at Abbeville, and Amiens. These were first noticed at Abbeville, and their true geological position assigned to them by M. Boucher Antiquity of the Human Race. 73 de Perthes, in 1849, in his ' Antiquities Celtiques,' while those of Amiens were afterwards described in 1855, by the late Dr. Rigol-. et. For a clear statement of the facts, I may refer you to the abstract of Mr. Prestwich's Memoir, in the Proceedings of the Royal Society for 1859, and have only to add that I have myself obtained abundance of Flint Implements (some of which are laid upon the table) during a short visit to Amiens and Abbeville. Two of the worked Flints of Amiens were discovered in the gravel-pits of St, Acheul — one at the deph of 10, and the other of 17 feet below the surface, at the time of my visit; and M. Georges Poucht, of Rouen, author of a work on the ' Races of Man,' who has since visited the spot, has extracted with his own hands one of these implements, as Messrs Prestwich and Flower had done before him. The stra- tified gravel resting immediately on the chalk in which these rudely fashioned instruments are buried, belongs to the post-pliocent period, all the fresh water and land shells which accompany them being of existing species. The great number of the fossil instru- ments which have been likened to hatchets, spearheads, and wedges, is truly wonderful. More than a thousand of them have already been met with in the last ten years, in the valley of the Somme, in an area 15 miles in length. I infer that a tribe of savages, to whom the use of iron was unknown, made a long sojourn in this region ; and I am reminded of a large Indian Mound, which I saw in St. Simond's Island, in G-eorgia — a mound 10 acres in area, and having an average height of five feet, cliiefly composed of cast- away oyster shells, throughout which arrow-heads, stone-axes, and Indian pottery are dispersed. If the neighbouring river, the Ala_ tamaha, or the sea which is at hand, should invade, sweep away, and stratify the contents of this mound, it might produce a very analogous accumulation of human implements, unmixed perhaps with human bones. Although the accompanying shells are of living species, I believe the antiquity of the Abbeville and Amiens flint instruments to be great indeed if compared to the times of history or tradition. I consider the gravel to be of fluviatile ori- gin, but I could detect nothing in the structure of its several parts indicating cataclysmal action, nothing that might not be due to such river-floods as we have witnessed in Scotland during the last half century. It must have required a long period for the wear- ing down of the chalk which supplied the broken flints for the formation of so much gravel at various heights, sometimes 100 feet above the present level of the Somme, for the deposition of fine /4 Antiqidty uf the Human Race. sediment including entire shells, both terrestrical and aquatic, and also for the denudation which the entire mass of stratified drift has undergone, portions having been swept away, so that what remains of it often terminates abruptly in old river cliffs, besides being covered by a newer unstratified drift. To explain these changes I should infer considerable oscillations of the land in that part of France — slow movements of upheaval and subsidence, deranging but not wholly displacing the course of the ancient rivers. Lastly, the disappearance of the Elephant, Khinoceros, and other genera of quadrupeds now foreign to Europe implies, in like manner, a vast lapse of ages, separating the era in which the fossil implements were frame i and that of the invasion of Gaul by the Romans. Among the problems of high theoretical interest which the recent prograss of Geology and Natural History has brought into notice, no one is more prominant, and, at the same time, more obscure, than that relating to the origin of species. On this difficult and mysterious subjects a work will ^-^ery shortly appear, by Mr. Charles Darwin, the result of twenty years of observation and experiment in Zoology, Botany and Geology, by which he has been led to the conclusion that those powers of nature which give rise to races and permanent varieties in animals and plants, are the same as those which in much longer periods, produce species, and. in a still longer series of ages, give rise to differences of generic rank. He appears to me to have succeeded, by his in^'^estigations and reasonings, to have thrown a flood light on many classes of phenomena, connected with the aifinitie?, geographical distribution, and geological suc- cession of organic beings, for which no other hypothesis has been able, or has even attempted, to account. Among the communications sent in to this Section, I have re- ceived from Dr. Dawson, of 3Iontreal, one confirming the discovery which he and I formsrly announced, of a land shell, or pupa, in the coal formation of Nova Scotia. When we contemplate the vast series of formations intervening between the Tertiary and Carbo- niferous Strata, all destitute of air-breathing mollusca, at least of the terrestrial class, such a discovery affords an important illus- tration of the extreme defectiveness of the o-eolosrical records. It has always appeared to me that the advocates of progressive deve- lopment have too much overlooked the imperfection of these records, and that, consequ3ntly a large part of the generalization in which they have indulged in regard to the first appearance of the different classes of animals, especially of air-breathers, will have to be modi- Professor George Wilson, 75 fied or abandoned. Nevertlieless, that the doctrine of progressive development may contain in it the germs of a true theory, I am far from denying. The consideration of this question will came before you when the age of the White Sandstone of Elgin is dis- cussed — a rock hitherto referred to the Old Red, or Devonian for- mation, but now ascertained to contain several reptilian forms, o^ so high an organisation as to raise a doubt in the minds of many geologists whether so old a place in the series can correctly be assigned to it. The Late Professor George WiIso7i of Edinhurgli. "We observe with deep regret the announcement of the decease of this excellent and able man. In the great work of wedding science to the useful arts, and in the power of making its hardest truths intelligible and acceptable to the common mind he has left few equals and no superior. We copy the following notice from the "Scottish Press": The death of Professor George Wilson is an event with cannot but be deeply and widely felt. By many amongst us it will be deplored as a grievous personal loss, to the interests of science generally, it is great indeed, but to the University of Edinburgh it may almost be said to be irreparable. We have no wish to magnify the acquirements of the dead at the expense of those of the living, nor would we wish it to be thought that we write under a sense of despondency occasioned by the removal of one who was ao wise and kind a counsellor; but Dr. George Wilson's connec- tion with the University and the department of science in which he laboured so ardently until the close of his life was in one sense so peculiar as to justify the remark we have made. The Chair of Technology which he was destined to fill for so short a time, was not so much created for him as by him. The foundation of his Professorship was, so to speak, only the recognition of his untiring efforts for the advancement of truth and the application of science to the industrial arts. It was felt not only that he was the best man who could be selected, but that he was the only man who fulfilled all the conditions necessary to render such a profes- sorship as that of Technology permanently efiective. The saying that thoroughly original men not only make their own instru- 76 Trofessor George Wilson* ments, but, humanly speaking, create occasion for the use of them, was never more clearly illustrated than in the case of Dr. George Wilson. And it is because we know that everything, or nearly everything, connected with the position from which death has just called him, owed its existence to his wisdom, his zeal, and his never flagging energy that we feel his death to be so great a public loss. It will never be possible to estimate with anything like correctness the amount of physical and mental labour which he endured in order to fulfil the objects contemplat- ed in the foundation of his Professorship, and to carry out the projected Industrial Museum of which he was appointed curator. His duties in the class-room, arduous as they were, did not represent a tithe of that labour. The clearness of his mind, the warmth of his heart, the graces of his style, and the natural buoyancy of his temperament, made his duties as a teacher seem as light as they were pleasant. No man better knew how to make the portals of the temple of knowledge inviting, and in a secular as well as a sacred sense, wisdom's ways were ways of pleasantness to him and all whom he sought to teach. Duty, " the stern lawgiver," ever were a smile for him, and his works abundantly prove that while he laboured as comparatively few are capable of labouring to extend the boundaries of knowledge, he never ceased to look forward, with the eye of steady faith, to that state of things in which we shall no longer see darkly as through a glass. It was his delight to think that those who reverently sought to know something of the Creator's work here, had begun studies that would never end, and he was wont to say that '' the shortest lesson in heaven will teach more than the longest upon earth. A brief notice like this affords us no opportunity of saying anything satisfactory as to the position to which Dr. George Wilson attained as a man of science and of letters. But it is scarcely necessary that anything should be said, for the sense of his loss attests the value of his scientific labours, and his books afford abundant evidence of the fine tone of his mind. His " Chemistry of the Electric Telegraph," and " Chemistry of the Stars" though scientific treatises in the best sense of the word? are felt by those who read them to be something more than this > they are the products of a highly poetical, as well as an accurate and well-balanced mind. His fertile imagination, and lively fancy, enabled him to impart not only lucidity, but attractiveness Reviews, Sfc, 77 to themes wliicli by others have been rendered obscure and uninviting. His delicate and often subtle humour, too, played around such themes relaxing their gravity and lighting them up. Above all these characteristics of his literary works, is the stead- fast faith and deep religious feeling which pervades them. In none is this so manifest, as in his Life of Dr. John Reid, one of the most delightful examples of biography within our knowledge. To Dr. George Wilson, religion was not only not a gloomy thing, but it was the brightness of existence. It not only cheered him in many days of prostration from severe bodily affliction, but it was an element in almost all his studies, and a thing of his daily laborious life. And we have reason to know, that during his last days on earth, he felt it to be indeed the peace of God, and the firm anchor of his soul. KEVIEWS AND NOTICES OF BOOKS. Handbook op Geological Terms and Geology, bj David Page, E.G.S., Author of the Advanced Text Book of Geologj. Edinburgh and London : "W. Blackwood & Sons. Montreal : B. Dawson & Son. pp. 416, $2. Such a Handbook as this is has long been a great desideratum to the reading public. The " hard words and forbidding techni- calities" of science which appear to beginners of so difficult ac- quirement, are here explained and made intelligible in brief and simple language. The ordinary reader will find the information he requires, generally in the first and second sentences of a defi- nition, while^what follows is more especially addressed to students and other professional enquirers. This book is just the thing for students, and for those who attend geological lectures, or read geological books. As the first book of the kind that has yet ap- peared, it is a most meritorious production. Although far from complete it yet contains nearly every term to be met with in ordinary books on geology. In no other single work can the same information be obtained. The defintions may be received with perfect confidence. The author is well known as a most painstaking and careful practical geologist. 78 Reviews f ^'c. Evenings at the Microscope ; or Researches among the Minuter Organs and Forms of Animal Life. By P. H. Gosse, F.R.S. Neio York : D. Appleton & Co. Montreal: B. Dawson & Son. pp. 480. Little need be said in commendation of this new work by Mr- Gosse. His popular writings in the department of Zoology are so well known and highly valued by Students of Natural History, that any thing on his favorite science, which he may now publish, is sure to meet with a favorable reception. To open the path to the myriad wonders of creation which, altogether unseen by the unassisted eye, are made cognisable to sight by the aid of the microscope is the aim and scope of this volume. The revelations of the microscope in the department of the organic world are of the most wonderful and interesting kind, and may well attract the attention of all intelligent and educated persons. The staple of this book consists of original observations by the author. He has set down simply what he himself has seen and what may be seen by any one with the aid of a microscope of ordinary power. He has relieved the dryness of technical description by a. colloqi- al and familiar style in a series of imaginary microscopical con- versaziones. The precision essential to science has, however, never been sacrificed. Throu2;hout the work considerable information is given on the selecting, securing and preparing objects for ex- amination under the microscope, which cannot fail to be highly useful to those who have not books at hand containing special directions on these points. In almost every instance the objects selected for illustration are common things, such as any one with. access to the sea-shore or country-side may easily obtain. The book contains one hundred and thirteen illustrations, all of which, with tbe exception of eighteen, are from the author s own pencil They are also, even in this American edition of the work, en- graved with much accuracy and beauty. To the young we can- not too highly commend this book. With the aid of a microscope its interest will be greatly increased, but with or without such a companion it cannot fail to prove highly instructive. Dura Den ; a Monograph of the Yellow Sandstone and its remarkable Fossil remains. By the Rev. John Anderson, D.D., F.G.S., &c. With illustrations. Edinburgh : Thos. Constable & Co. Montreal : B. Dawson & Son. — imp. 8 vo. pp. 96, $3-50. This is a truly sumptuous book which any geologist will regard as a real luxury. The illustrations are in the highest style of Reviews, ^'c« 79 lltliograpliic art and artistic beauty. The two finest and largest are drawn by the f\iir hand of Lady Kinnaird, and are of unquestionable excellence. The writer is well known as a distin- guished amateur geologist. His name is associated with some im- portant discoveries in this department of Science. Lately the remarkably well preserved fossils of a district in Fifeshire, Scot- land, called Dura Den, has attracted the attention of geologists and led to an interesting determination of the position of the rocks in which they are embedded. The fossils are now regarded, on almost unquestionable evidence, to belong to the Devonian or old red Sandstone formation. At first, from their contiguity to the coal fields of Fifeshire^ these rocks were supposed to have some relation to the lower members of the Carboniferous system, but the careful examination of their fossils and the relat- ed strata have led the chiefs of geological science to regard the Yellow Sandstone of Dura Den, as a curious and most interesting section of the great Devonian System. We cordially reconi. mend this book to those interested in the progress of Geological Science. Nuggets from the oldest Diggings or Researches in the Mosaic Crea- tion. By R. "W. Yandyk. Edinburgh: Thos. Constable & Co. Montreal : B. Dawson & Son. This is another book on the great question of the reconciliation of the Mosaic Narrative of Creation, with the facts of physical science. Notwithstanding the uncouth title, the book is written with much vigour and eloquence. There is no pretension to a critical examina- tion of the text with this branch of the subject our author does not intermeddle. Nor does he claim any higher acquaintance with science than that which may be obtained from a careful study of good books. The author persuades himself that he has made a grand discovery which removes all the difficulties which have hitherto perplexed the wisest of men, and sheds a perfect flood of light upon the scripture narrative. He is evidently in a very Lappy frame of mind, and writes in a style of delightful enthusiasm. " Happy is he who knoweth the causes of things." Our authors' idea is that, with the exception of the very first act, which was the creation of the substance of the universe, the whole events narrated in Genesis i. were truly effects of the laws given to the created mass, showing themselves gradually and in succession, and by a process 80 Reviews, Sfc. which, if witnessed, would have appeared to be exactly the same natural and unmiraeulous operation of cause and effect with which we are familiar. After the first creative act, what is described is the formation of earth and its tenants out of a disorderly mass of matter ; and this is represented as having been accomplished by movements within the mass itself, that is to say, by means of second causes," This is the theory which the book works out with some ability and ingenuity. If it is not altogether new, it is at least modern. We cannot say we are convinced of its truth. We have no faith in unscientific treatments of the physical phen- omena of the universe, or in unlearned criticisms of the sacred text. No man should attempt the discussions of the topics con- tained in this book who has not had practical acquaintance with the subjects which it involves. The idea of all pervading law in the production of physical phenomena is that which Baden Powell attempts to demonstrate with rare ability in his recent works. We do not recognise any special feature in the " Nuggets from the oldest Diggins" that entitles it to a very high rank in the litera- ture of the subject on which it treats. It may be read with in- terest by the curious, and be regarded as another addition to the unsuccessful attempts to settle the disputed interpretation of the Mosaic cosmogony. Ox THE Origin of Species by means op Natural Selections, or thk PRESERVATION OP FAVOURED RaCES IN THE STRUGGLE FOR LiFE. By Ch. Darwin, M.A., &c., «fec. New York: D. Appleton & Co. Mon^ treal : B. Dawson & Son. This is an abstract of a larger work in course of preparation. It is entitled to most careful perusal. The author is a well known and distinguished Naturalist. He has given much attention to and spent now twenty years of his life in the prosecution of the sub- ject of this book. The title is a good description of its contents. It deals with questions of Natural History in a way most masterly and profound. That its views will meet with much opposition is to be expected. Few will be disposed to go the sweeping length to which our author is disposed to go in the logical issue of his theory. We merely call attention to this able work in the mean time. It promises to create quite a furor in the minds of scien- tific enquirers. We hope to present our readers with a thorough review of the work either from the pen of one of the Editors, or from the pages of one of tlie earliest scientific magazines of Europe or America.

With the exception of the Rhopalocera (Butterflies), the greater portion of the Lepidoptera collected are stiU undetermined. Some of the Heterocera (Moths) enumerated below, were named for me, at the British Museum, by Mr. Francis Walker, to whom I am much indebted. I obtained a great number of beautiful larvae in October, but from the difficulty of transporting them from place to place, when travelling, I failed to rear any of them. From the end of May till August, Nbctuidce and Geometndce swarmed at dusk in the woods, the light of our camp-fire often attracting them in great numbers into our tents, and the numerous delicate Micro- lepidoptera would have delighted Mr. Stainton. Rhopalocera. 1. Papilio iumus, Linn., (Tiger Swallow-tail). Figured and described in the " Canadian Nat. and Geol.," Vol. 2, pi. 3, p. 223. Abundant throughout the whole of the district traversed. First observed 30th May, at Sixteen Island Lake, Montcalm, and became very numerous by the middle of June^ continuing so until the beginning of July, at which time most of them were much worn, and they disappeared altogether by the end of the month. The beautiful apple-green larvae were very abundant at the end of August and during the first week of September, at Hamilton's Farm on the Biver Valley of the River Rouge f ^'c, 87 Bouge. At that time we were camped on the grass of the clear- ino", under some scattered elm and ash trees, and the larvae, which were numerous in the tents, appeared to have been blown out of these trees by the high winds, and were rapidly crawling about in search of a suitable place to spin their suspending girths, and un- dergo their transformations. Just before assuming the pupa state, they became dark brown in colour, with some lilac stripes and spots. On the 31st August, I met with a larva on an alder bush, across a leaf of which it had spun a bed of silk, and was repos- ing upon it in its usual manner, with the anterior segments drawn in and swollen out, so as to render the ocellated spots on the third segment very conspicuous. When in this position, these larvae, if disturbed, rock themselves slowly from side to side, throwing out the forked orange tentacle, which is usually concealed from view in the segment behind the head, emitting at the same time a very acrid odour. The pupa is whitish-brown on the back and abdomen, with a darker line down the sides, and the wing-cases are dark brown, or black. This splendid butterfly frequently as- sembles in great numbers about wounds on the roots of trees from which sap exudes, and also about decaying fish and animal matter. On the shores of Sugar-bush Lake in the Township of Montcalm, on the 25th June, I counted fifty- six individuals crowded together in a space, not exceeding six square inches, where a dead cat-fish had lain for some time, and others were constantly ariving, flying straight to the spot against the wind, as though they had scented it from afar. On several occasions more than a dozen specimens -were captured at a single grasp of the hand, having become so gorged and drowsy with their disgusting repast, as to be unable to fly. 2. F. asterias^ Fab. (Black Swallow-tail.) — Figured and des- cribed in the "Canadian Nat. and Geol." vol. 2, pi. 3, p. 220. A large black butterfly seen by myself, as it sailed rapidly through the woods, on the borders of Chain Lake, Montcalm, 17th June, I supposed to be this species. It was not, however, again met with, which is not surprising, considering the scarcity of Umbelliferous plants in this district. 3. CoUas phUodice, Godt. (Clouded Sulphur.) — Figured and described in the " Canadian Nat. and Geol." vol. 2, pi. 4, p. 313. Numerous at Grenville on the 5th June, but I did not observe it again till the 30th of that month, after which it was not uncommon :along the banks of the Kouge. At Hamilton's farm^ 50 miles up 88 Natural History of the the river, it was quite numerous, especially in August and Sep- tember. The last date at which I observed it there, was the 13th September, when it was still abundant, and I then captured a specimen apparently just evolved. I saw several individuals at Grenville, October 14th and 18th, and on my return to Montreal on the 19th of that month it was still rather numerous there. As the larva of this butterfly feeds on various species of Trifolium it is not to be looked for in uncleared districts, and in fact it is only to be seen around clearings and open places, where the clovers have been introduced either by accident or design. 4. PieWs oZeracea, Harris (Grey-veined White). Described in the " Canadian Nat. and Geol." vol. 2, p. 347. Abundant through- out the whole district. First observed near Grenville, 14th May, and was then numerous in the woods of that township. It con- tinued abundant up to the end of June, but was not seen after- wards till the end of August, when I observed a few worn indivi- duals at Hamilton's Farm. This species also, had the habit of pitching upon the dead fish and offal lying round our camps, but never assembled in any great numbers. 5. Danais Arcliippus, Fab. (Storm Fritillary.) — Figured and described in the Canadian Nat. and Geol. vol. 2, pi. 6, p. 350. A single specimen, which appeared to have been recently evolved, was seen by myself, flying across the Rouge, a little above Silver Mountain, on the 12th August. The different species of J.rc?e- pias^ which constitute the food-plants of the larva, are sparingly distributed in this district, and accordingly this butterfly is seldom met with. 6. Satyrus^ Portlandia, Boisd. (Pearly Eye.) First seen about the camp on the south side of Bevin's Lake, Montcalm, on the 2nd July, after which it was met with abundantly in the woods along the Bouge as far as Silver Mountain, near which on the 6th August, those seen were much wasted, and they soon afte entirely disappeared. The specimens collected agree tolerably ac- curately with Boisduval's figures and descriptions of Satyrus Portlandia. It is figured under the name of Hipparchia An- dromacha, Hiibner, in Say's "American Entomology," vol. 2, pi. 36, and in Gosse's " Canadian Naturalist" p. 246. In the latter work it is spoken of as very rare in the Eastern Townships, and Prof. T. P. Kirtland, says it is among the most rare of the butterflies of Ohio. Being generally supposed to be a southern species, it is not little remarkable that it should be so abundant * (DeMs.) Valley of the River Rovge, c^e. 89 to tlie north of the Ottawa. I have also met with it near Mon- treal. 7. HipparcMa nephcle ? Kirby. Abundant amongst grass on Hamilton's Farm, from the 22nd August to the beginning of September, but all seen were much worn. It is a common species in hay-fields at Montreal and Sorel, and is described in " Fauna Boreali-Americana," p. 297. 8. Limenitis Arthemis, Drury. (Banded Purple). Figured in Gosse's " Canadian Naturalist" p. 220. First seen at Sugar-bush Lake, Montcalm, on the 26th June, after which it became the most abundant species and continued so until the end of July, when all observed were much worn, but linsjered on till the middle of August. It frequently assembles in astonishing numbers round old lumbering camps, &c., congregating about the tea-leaves and other refuse lying about such places. On the 15th July, on the site of a lumbering camp and timber roll- way, on the banks of the Rouge, about three miles above the In- dian Village in the Township of Arundel, I saw the most extra- ordinary assemblage of butterflies I ever beheld, several hundreds of this species being congregated together in groups consisting of from twenty to fifty individuals in each, whilst many others flew around and rendered it difiicult to arrive at an accurate estimate of their numbers ; nevertheless I am convinced that I am within the mark, when I state that there were more than three hundred as- sembled within a space of a few square yards. This species is very restless and active when on the ground, constantly opening and shutting its wings, unrolling its tongue, and running to and fro very rapidly, and even when feeding is not easily surprised. It flies freely in cloudy weather and quite late in the afternoon. According to Prof. Kirtland it is a rare species in Ohio. 9. Cynthia cardici, Linn. (Painted Lady). Described in the " Canadian Nat. and Geol." vol. 3, p. 346. But one specimen was met with, which was on the 21st August, at Hamilton's Farm, where the common thistle (^Clrsium lanceolatum) , the food-plant of its larva, is plentiful about the fields. 10. Vanessa Atahnta, Linn. (Pied Admiral). I observed a butterfly which appeared to be of this species, on the 24th June, at Sugar-bush Lake, Montcalm. 11. V. Antiopa, Linn. (Camberwell Beauty). Figured and described in the " Canadian Nat. and Geol.," vol. 2, p. 93. Rather common at Grenville on the 13th May ; a few specimens were seen 90 Natural History of the in the Township of Montcalm in June, and near Silver Moun- tain on the Rouge, on the 12th of August. 12. V. Milberti, Grodt. furcillata, Say. (Forked). Common at Grenville, 14th May, not seen again until July 10th, on the Rouge, after which it was observed occasionally at Hamilton s Farm, up to the 31st August. 13. F. J. album, Boisd. (Compton Tortoise). A common species throughout the district, from the l9th May to the end of September. I observed one near Grenville on the 18th Octo- ber. 14. Grapta Prog lie. Fab. (Green Comma). Abundant every- where from the 14th May to the middle of September. On one occasion an individual of this species pitched on my hand and I caught it between my fingers. 15. G. C. album, Godt. (Orange Comma). The species of the genus Grapta (popularly termed Commas, from the silver spots in the centre of the hind-wings on the under side, which resemble an inverted comma) are so subject to variation, that it is extremely difficult to determine them, unless they are reared from the larvse. I, however, took several specimens of a species which I believe to be G. C. album along the Rouge in July and August. 16. Argi/nnisDapJmis? CvsLmer (Small Silver-spot Fritillary). First seen at Bevin's Lake, Montcalm, 2nd July, andfrom that date it was abundant all the way up the Rouge as far as Hamilton's Farm, at which place, on the 25th of August, I saw a specimen perfectly fresh, whilst many others were flying about in a worn condition. It was very numerous on the flowers of Asdepias incamata, near the Indian Village on the 18th July. The last date at which it was observed by me was 12th September. I am of opinion that Boisduval was in error in considering A. Aphrodite, Fab., and A. Cybele, Fab. as one and the same species. There are at least three closely allied species of Argynnis inhabiting Canada, but nothing short of breeding each from the larvae will satisfactorily separate them. Two of my specimens agree best with Cramer's figure of A. Daphiis, but a third diff'ers considerably and may be another species. They are all too small for A. Cybele, Fab. 17. A. Myrina, Cramer. (Pearl-border Fritillary). First seen at Grenville 5th June. Common at Bevin's Lake, Montcalm, at the beginning of July, and at Hamilton's Farm up to the 31st August. Valley of the River Rouge ^ ^c. 91 18. A. Bellona, Fab. One specimen taken near Mr. Thomp- son's clearing on the Kouge, in the Township of Arundel, on the 30th June. It was not again met with, 19. Melitcea Thaws, Cramer, Oocyta, Hiibner, (Pearl-crescent Fritillary). First observed at Sugar-bush Lake, Montcalm, 29th June. In copula and rather worn 2nd July about Bevin's Lake. A few seen a few miles up the DcTil's River, 14th July. 20. Thecla (?) A large ThecJa was seen by me at the Huckle- berry Rapids on the Rouge, 2nd Range of De Salaberry, on the 30th July, but I failed in my attempts to secure it, and could not recognise the species, nor did I meet with any other of this genus. 21. Lyccena Americana, Harris (American Copper). Numer- ous from the 21st to the 31st August, on grass-land at Hamilton's Farm, where its food-plant, the sorrel {Rumex acetosella), abounds. 22. Polyommatns pseudargiolus, Boisd. (Spring Azure). Nu- merous on the 14th May, in the woods of the Township of Gren- ville. The males were extremely abundant, congregating round putrid fish on the shores of Sixteen-Island Lake, at the end of May ; I saw worn specimens as late as the 2nd July, about Bevin's Lake. When in a canoe on Sixteen-Island Lake, one of these beautiful little butterflies pitched on my hand and remained there for some time, 23. Pamphila (?) Two specimens of a dingy grey species of Shipper were captured, one at Sugar-bush Lake, June 26th, and the other at Bevin's Lake, 2nd July, 24. Pamphila (?) One specimen of a Pamphila, resembling P.paniscus (Chequered Shipper) of Europe, was taken near Bevin's Lake, Montcalm, 2nd July. Two or three other species of Pamphila were taken in the Townships of Montcalm and Arundel, and at Hamilton's Farm, in June, July and August, which I have been unable to deter- mine, and which are probably undescribed species. Heterocera, SPmNGINA. Sphinx. I captured two species of Sphinx on the Rouge, in the Townships of Arundel and DeSalaberry, in July, allied to S. halmioe., Abbot and Smith, and S. gord'ms, Cramer, but not agreeing satisfactorily with the descriptions of those species as given by Dr. Harris in his Catalogue of American Sphinges, (Amer. Jour. 92 Natural History of the Sci. vol. xxxvi). According to Mr. Walker, neither of tliem is in the collection of the British Museum. Dead fish appear to be very attractive bait for Sphinges as well as other Lepidoptera, one of the species above mentioned having been taken whilst hovering over a dead carp lying by the water side, and many others were seen under similar circumstances. On the 11th August, when camped on a low flat at the base of Silver Mountain on the Rouge, I obtained a Sphinx larva, which from my notes, ap- pears to have resembled that of S. Kalonice, as described by Harris (vide Amer. Journ, Sci. vol. xxxvi, p. 295). It was light green, with seven obHque yellow stripes edged above with dark purple, on each side ; head yellow, with a vertical band of dark brown on either side ; caudal horn, blue, covered with small black tubercles, and tipped with black. It appeared to have been washed by the heavy rain which had just fallen during a violent thunder storm, from the soft maples [Acer ruhrimi), which almost exclu- sively surrounded the tents, and on one of which it was crawling. Another splendid larva was found on the 19th September, feeding on a bush of Myrica gale, growing on the shores of Green Lake, adjoining the Lake of Three Mountains, in the county of Ottawa, about five miles from Hamilton's Farm. The following is the description of it which I made at the time : '' Deep olive- green, covered with minute spots of white, edged with black ; seven oblique pink stripes, edged above with black and below with pale yellow, on either side ; caudal horn, black ; spiracles, orange ; pro-legs, yellow ; a stripe of light green on each side of the head." The minute white spots surrounded by black, thickly covering the whole upper surface, gave it a striking and most interesting re- semblance to the scurfy resinous dotted leaves of its food-plant, the Bog Myrtle or Sweet Gale. This beautiful larva changed to a pupa which unfortunately perished during the following winter. Smerinthus. I obtained two larvae, belonging to this genus, under elm trees at Hamilton's Farm, on the 3rd and 4th Septem- ber, of which the following are descriptions: No. 1, pale green, whitish on the back, with oblique stripes of white and dark green on the sides. No. 2, green, with oblique tuberculated stripes on the sides, and two tubercles on each of the second and third seg- ments, Trochilium. On the 25th June, at Sugar-bush Lake, I cap- tured a beautiful and apparently undescribed species of Trochi- lium, sitting on the blossoms of Viburnum ojmlus which were Valley of the River Rouge, S^c. 9'3 much frequented by insects of all orders. The anal tuft is deep orange; antennae, black; expansion of thewings 11 lines; length of the body 5 lines. BOMBYCINA. 1. Ctenuclia Latreillana, Kirby. (Ccerulean). Described in " Fauna Boreali- Americana," p. 305. One specimen taken on the 16th July, near the Indian Village on the Rouge, Township of Arundel. 2. Crocofa hrevicornis, Walker. Described in " British Museum Catalogue Lepid. Het." part II, p. 535. Observed in open places at Huckleberry Rapids, DeSalaberry, and numer- ous amongst grass at Hamilton's Farm, end of July and August. 3. Medaria Mendica, Walker. (Buff Muslin). Described in "British Museum Cat. Lepid. Het." Part II, p. 576. Not abund- ant in this district, but occurred near Bevin's Lake, Montcalm, in July. 4. Arctia PartJienos, Harris (Great Northern Tiger). On the 19th July, five miles up the Devil's River, a tributary of the Rouge, I took a fine Arctia agreeing in every respect with the figure and description of A. Parthenos, given by Dr. Harris in Agassiz's " Lake Superior," p. 390, pi. 7, fig. 4, with the excep- tion that it hsiafive, instead of tJu^ee cream-coloured spots on the costal edge of the anterior wings. 5. Hypercompa Lecontei, Boisd. (White Tiger). Occurred at various places in the Townships of Montcalm, Arundel and DeSalaberry, during the month of July. H. confinis and contigua, Walker, (" Brit. Mus. Cat. Lepid. Het." part III, p. 651), appear to be merely varieties of this very variable species. 6. Hales ido ta annuUfascia, Walker. Described in Brit. Mus. Cat. Lepid. Het. part III, p. 733. I found cocoons of a Muff Moth under stones, 22nd May, near Sixteen Island Lake, Went- worth, most probably belonging to this species, which abounds near Montreal. Mr. Walker's H. annulifascia appears to me to be identical with SojyJiocanipa Co.ryce (Hickory Jussock Moth) of Harris, (vide Fitch's "Noxious Insects of New York," p. 163). 7. Orgyia leucostigma, Abbot and Smith (American Yapourer). Vide Fitch's " Noxious Insects of New York," p. 213. The males were numerous flying in the sunshine at Hamilton's Farm, at the end of AugTist and beginning of September. 94 Natural History of the 8. Telea Pohjpliemus, Hiibner, (Eyed Emperor). Abundant at the end of June and beginning of July, about Bevin's Lake, Township of Montcalm. I also found numerous empty cocoons, near Sixteen Island Lake, "Wentworth, and at Huckleberry Rapids, DeSalaberry, and the beautiful larva, (vide the excellent figure in Gosse's '' Canadian Naturalist," p. 309,) was common on elm trees at Hamilton's Farm, being full grown and spinning up at the end of August. This fine species is therefore distributed over the whole district traversed. These gigantic Emperor Moths have a very strange appearance when seen against the clear sky of a fine summer evening, as they fly over the lakes. NOCTUINA. 1. Thi/atira scripta, Gosse. (Pink Arches). Figured in Gosse's " Canadian Naturalist," p. 249. This most beautiful species was abundant in the Townships of Montcalm and Arundel, at the end of June and the beginning of July. 2. T. cymatophor aides ^ Guen. Common at Sugar-bush and Bevin's Lakes, Montcalm, and mouth of Devil's River, Arundel, at the end of June and July ; also at Trembling Mountain Lake, Grandison, 7th September. 3. GrapTiipliora C> nigrum^ Linn. One specimen taken at Huckleberry Rapids, DeSalaberry, 24th July; and another worn one at Hamilton's Farm, 28th August. 4. G. JDahlii, Hiibner. One specimen taken near Gate Lake, Wentworth, 17th May. 5. JEJuplexia lucipara, Linn. (Small Angleshades) — Common in the Township of Montcalm in June. 6. Plusia mortuorum. Abundant flying by day at Hamilton's Farm in the end of August. GEOMBTRINA. 1. Angerona crocataria, Fab. (Lemon beauty). Common in the Townships of Montcalm and Arundel, frequently flying by day in July. The female of this species is much larger, and paler in colour than the male. 2. Sicga solfataria, Guen. This lovely little moth was not uncommon at the end of July, in the Township of DeSalaberry. It bears a great resemblance in colour, markings, and form to Ennonios macularia^ Harris. (Vide Agassiz's " Lake Superior," p. 392, pi, 7, fig. 3.) Valley of ihe River Rouge, ^c. 95 3. Ellopia ccqualiaria. Township of Montcalm, June. 4. Nematocampa filamentaria, Gu^n. Huckleberry RapidS; 2ncl Range, DeSalaberry, 27th July. 5. Endropia tigrinaria^ Guen. Very abundant in the Town- ship of Montcalm at the end of June. 6. Melanippe gothicata, Guen. Extremely numerous, especial- ly in rocky woods, in the Township of Montcalm, during the month of June. It flies in such a manner that the white bands across the wings appear to form a complete circle in the air. It is closely allied to M. hastata of Europe. 7. Scotosia undulata, Linn. (Scallop Shell). Common in the end of June and the beginning of July in the Township of Mont- calm. Those collected are exactly similar to English specimens. PYRALIDINA. 1. Pyralis^ n. sp? Huckleberry Rapids, DeSalaberry, 27th July. Mr. Walker supposes this to be a new species, and the fol- lowing is a description of it : — Anterior wings, dull pink, crossed by two black transverse lines, the first of which, situated near the base, is straight, and has a yellow spot on the inner side, occupy- ing the angle which it forms with the costa ; the second, situated beyond the middle, is bent, forming an obtuse angle before it reaches the costal margin, where it has a yellow crescent-shaped spot on the outer side. Posterior wings, dusky- white at the base, with a broad, pale black, sub-marginal band and crossed by two black transverse lines. Expansion of the wings \2\ lines; length of body 4 lines. 2. Bleptina surrectalisj Gu^n. Huckleberry Rapids, DeSala- berry, 4th August. 3. Anania octomaculata, Linn. (White spot). One specimen taken on the 2nd July, near Bevin's Lake, Montcalm. It occurs also on the northern shores of Lake Superior and in Europe. 4. Hydrocampa. A species of Hydrocampa was abundant, flying over aquatic plants in a small lake near Hamilton's Farm, 15th August. 5. Botys verticalisy Linn. (Mother of Pearl). Not uncommon at Huckleberry Rapids, DeSalaberry, about the 1st of August. Those collected have been compared with British specimens and appear to be identical. 6. Euhulea. A small species apparently closely allied to the European E. samhercalisj Sehiff., was very numerous on the bloa- 96 • Natural History of the soms of the Easpberry, (Rubus strigosus) near Bevin's Lake, Montcalm, at tlie beginning of July. TORTRICINA. Tortrix. On the 19tli July, five miles up the Devil's Eiver, I found a mass of web, spun by larvae, over the leaves and branches of the Indian Hemp (^Apocyniim cannahinum') , which was full of pupge of a Tortrix, and at the end of the month, those I collected, produced the perfect insect, but I have been unable to determine either this or any other of my 3Eero-Lepidoj)tera. MOLLUSOA. Some of the Terrestrial Gasteropoda, enumerated below, were deter- mined by W. G. Binney,Esq., of Burlington, New Jersey, and a portion of the Fresh Water species, and the Naiades, by Dr. Isaac Lea, of Phila- delphia. It is not a little remarkable that Unio radiatus, which, as I am informed by Messrs Billings and Bell, is very abundant in the Ottawa at L'Original, and at the mouth of the Rouge, is not found higher up the latter river. Shells of the genera LimncBa, Physa and Planorbis, were remarkably scarce in every lake except Sugar-bush Lake, Montcalm, and a small lake one mile west of the Indian Village on the Rouge in the Township of Arundel, and in fact ;it was only in places where the water was shallow and the bottom soft that they occurred at all. The valves of the Unio and AnodontcB were very much eroded in most of the lakes. G-ASTEROPOD A. ( Terrestria I.) 1. Tebennopkorus caroliniensis, Bosc. (Great grey Slug) — Common under bark of decaying logs, &c., throughout the district. 2. Succinea obliqua, Say. — Abundant under decaying logs on grass- land at Hamilton's Farm, in August. It occurred very sparingly on the leaves of bushes, in other parts of the district. 3. Helix albolabris, Say (White-lipped Snail). — Not very common; Township of Wentworth, Montcalm and Harring- ton. 4. " exoleta, Binney. — Not uncommon under dead logs in the Townships of Wentworth,Harrington and DeSala- berry. 5. " monodon, Rackett. (One-toothed Snail.) — Sparingly met with ; portage from the Indian Village to Bark Lake, Arundel ; Hamilton's Farm and near the Lake of Three Mountains. 6. " concava, Say. — Abundant under dead logs ; Townships of Wentworth, Montcalm and Arundel. On one occasion I found an individual of this species devouring the animal of Achatina lubrica, having made a hole through the spire of its shell Valley of the River Rouge, ^c, 97 T. Helix pulchella, Miill. — Occurred under stones at Carillon, but was not elsewhere met with. 8. " Sayii, Binnej. — Several specimens were found by myself under dead logs in the woods near Doran's Lake, in the 10th Range of Grenville. 9. " labyrinthica, Say. — Common under dead logs, bark of stumps, in moss on the trunks of trees, &c. ; Townships of "Wentworth, Montcalm and Arun- del. 10 " alternataj Say. — Abundant throughout the district, under dead logs and ascending the trunks of trees after rain. 11. " s^ria^eZ/a, Anthony. — Very abundant under stones and dead logs everywhere throughout the district. 12. " arborea, Say. — Plentiful under bark of decaying trees, &c., throughout the district, 13. " chersina, Say. — Common under dead logs, &c., over the whole district. 14. " lineata, Ssij. — Abundant throughout the district. 15. Bulimus marginatus, Say. — Near Gate Lake, "Wentworth, and Sugar- bush Lake, Montcalm. 16. Jlchatmaluhrica, Miill. — Common under dead logs near Gate Lake, Wentworth, and Bevin's Lake, Montcalm. 17. Vertigo Gouldii, Binney. — In moss (^Neckera pennata) on tree trunks ; Sixteen Island Lake, Montcalm. 18. Pupa (undetermined) — With the last species. 19.

It was most numerous in the stream through which the waters of Bevin's and Bark Lakes are discharged into the Rouge, where, in shallow places, thousands might be seen buried in the mud with only the tips of their valves sticking out, and as thick as they could lie together.

The difference in level between these lakes and the Rouge is only a few feet, but there is a verj' considerable rise between them and Chain and Sixteen Island Lakes, which also empty their waters into Bevin's Lake, but by a very circuitous route.

The physicist finds himself in this position when required to explain the nature of matter, or the cause of gravitation or cohesion, or the essence of the mysterious influences of light, heat, and electricity. The chemist is equally bafiled in the presence of those mysterious atoms which are in all his processes, yet are not perceptible to his senses The physiologist stands awe-stricken in the presence of a micro, scopic cell whose structure he knows, but whose origin and won derful vital endowments he fails to comprehend. The geologist and the systematic zoologist are haunted in their dreams by those multifarious species that appear and disappear, like phantoms on the stage of geological time, yet seem so fixed and unchangeable in existing nature. True science is always humble, for it knows itself to be surrounded by mysteries — mysteries which only widen as the sphere of its knowledge extends. Yet it is the ambition of science to solve mysteries, to add one domain after another to its conquests, though certain to find new and greater difficulties be- yond. Hence we find every difficult problem assailed by a con- stant succession of adventurers, some of them content cautiously to explore the ground and prudently to retreat where to advance is no longer safe ; others gathering all their strength for a rush and a leap into an unknown and fathomless abyss. Both classes do good to science. The first show us the real nature of the difficulties to be overcome or to be abandoned as hopeless. The second we follow to the last crumbling margin of sound fact and deduction on which their feet have rested before their final plunge, and thus gain an experience that otherwise we should not have had the courage to seek. The question of the origin of species yields in difficulty to none of the problems to which we have referred above, and Mr. Dar- win's book is a noted instance of the second of the methods of * On the Origin of Species by means of Natural Selection, or the Pre- servation of Favoured Races in the Struggle for Life ; by Charles Dar- win, M.A. 1 vol. post 8vo. pp. 502. London : John Murray. New York: Appletons. Montreal: Dawson. 1860. On the Origin of Species, 101 treatment which we have indicated. We do not however value him the less on account of his boldness and rash self-sacrifice in the cause of science. We follow him with pleasure over many- agreeable and instructive paths not previously explored, and we shrink back only when he leads us to the brink of a precipice, and we fail to perceive the good land which he says lies beyond, or to place confidence in the bridge, thinner than gossamer, which he has woven to bear our feet over the gulf that separates the proved ground of specific variability from the mystery of specific difference. We regard this as the most accurate and concise statement that can be made respecting the character of this book. It elaborately investigates the question of variation of species, and illustrates its laws in a very full and satisfactory manner, though giving to some of these laws an undue prominence as compared with others. It then attempts to apply the laws of variation to an entirely different series of phenomena, those of specific diver- sity, and finding some analogies between the characters that dis- tinguish species and varieties, seeks on this ground to break down all specific distinction in respect to origin, and to reduce all species to mere varieties of ancient and perhaps perished prototypes. The work thus divides itself naturally into two distinct and quite dissimilar portions: 1st. The careful induction of facts bearing on the nature and laws of variation, in which the author appears in all his strength as a patient and reliable zoologist ; and, 2nd, The wild and fanciful application of the results thus attained to another class of phenomena with which they have no connection except that of mere analogy. We shall endeavor to distinguish these two portions of the work, but cannot avoid treating of them together. Variation occurs under two very different conditions. It takes place in domesticated animals and plants, and in animals and plants in a wild state. Very properly our author first examines its conditions under domestication, in which state variation is much more extensive and also more easily observed. The great variations that occur in a state of domestication are no doubt due to changed and unnatural conditions of life ; but farther than this we know nothing of their precise causes. On this subject our author indulges in some preliminary speculations, and tries to rid the subject of what he terms misconceptions, some of which are, however, only facts too stubborn to be bent to his theory. For example, in speaking of the prevalent idea, that domesticated 1 02 Review of Darwin animals have been chosen by man on account, among other things, of their capacity for variation, he says : — "I do not dispute that these capacities have added largely to the value of some of our domesticated productions ; but how could a savage possibly know- when he first tamed an animal whether it would vary in succeed- ing generations, and whether it would endure other climates? Has the little variability of the ass or the guinea-fowl, or the small power of endurance of warmth of the reindeer or of cold by the common camel, prevented their domestication? I cannot doubt that if other animals and plants equal in number to our domesticated productions, and belonging to equally diverse classes and coun- tries, were taken from a state of nature, and could be made to breed for an equal number of generations under domestication, they would vary on the av^erage as largely as the parent species of our existing domesticated productions have varied." On reading these sentences it must occur to any reflective reader, 1st. That savages very rarely tame animals. 2d. That if savages or others attempted to tame animals indiscriminately, they would fail in many cases, and these in the very cases in w^hich species could endure little change. 3d. Animals little variable, like the rein- deer and the camel, have little geographical range, and this just because of the fixity or tenderness of their constitution. 4th. Even the capacity of breeding at all under the changed conditions o^ domestication, is wanting in some species. In short, there is no reason whatever to believe that species are equally variable ; but, on the contrary, that they differ very much in this respect, — as naturalists have always maintained. In the same loose way he treats the doctrine of the tendency of varieties to revert to the original types of the species. This, our author admits, if estab- lished, would overthrow his whole hypothesis, and he gets rid of it by denying the evidence of reversion afforded by so many of our domestic animals and cultivated plants, and by farther affirm- ing that such, reversion, if it does occur, amounts to nothing, because produced by external causes. Certain species, by the external causes applied in domestication, are caused to vary. These causes being removed, as every one knows, they gradually lose their acquired and unnatural characteristics ; but, according- to Mr. Darwin, this gives no evidence of an original type, but only of the operation of other causes of change, tending in some other direction. The argument would be good if we could have species destitute of all distinctive characters to begin with ; in On the Origin of Species* 103 other words, if we could create species. But as the case stands, it is a mere petitio principii. In this way our author, in the opening paragraphs of his first chapter, quietly ignores a number of facts essential to the validity of the received views of species, and so leads the unwary reader to enter on the consideration of variation with an impression already formed that varieties and species are not distinguishable. We take the liberty of entering on the enquiry in another spirit, and of beginning with the fact that we have species which have remained distinct in the whole period of human experience, and also as far back in geological time as we can trace any of them. This being premised, we may enquire what variations man has been able to eflfect in those species which he has domesticated, and by what processes ?ind under what laws these changes have occurred. These changes have been very great. Mr. Darwin has studied the domestic pigeon as a convenient instance, and his investiga- tions on this animal are worthy of all praise, and establish most clearly the great amount of variation of which some species are susceptible. We quote this in full, as the most valuable portion of the book : — "Believing that it is always best to study some special group, I have, after deliberation, taken up domestic pigeons. I have kept every breed which I could purchase or obtain, and have been most kindly favoured with skins from several quarters of the world, more especially by the Hon. W. Elliot from India, and by the Hon. C. Murray from Persia. Many trei.tises in different langu- ages have been published on pigeons, and some of them are very important, as being of considerable antiquity. I have associated with several eminent fanciers, and have been permitted to join two of the London Pigeon Clubs. The diversity of the breeds is something astonishing. Compare the English carrier and the short -faced tumbler, and see the wonderful diflference in their beaks, entailing corresponding diflferences in their skulls. The carrier, more especially the male bird, is also remarkable from the wonderful development of the carunculated skin above the head, and this is accompanied by greatly elongated eyelids, very large external orifices to the nostrils, and a wide gape of mouth. The short-faced tumbler has a beak in outline almost like that of a finch ; and the common tumbler has the singular and strictly inherited habit of flying at a great height in a compact flock, and 104 Review of Darwin tumbling in the air head over heels. The runt is a bird of great size, with long massive beak, and large feet ; some of the sub- breeds of runts have very long necks, others very long wings and tails, others singularly short tails. The barb is allied to the car- rier, but, instead of a very long beak, has a very short and very broad one. The pouter has a much elongated body, wings, and legs ; and its enormously developed crop, which it glories in in- flating, may well excite astonishment and even laughter. The turbit has a very short and conical beak, with a line of reversed feather down the breast ; and it has the habit of continually ex- panding slightly the upper part of the oesophagus. The Jacobin has the feathers so much reversed along the back of the neck that they form a hood, and it has, proportionally to its size, much elongated wing and tailfeathers. The trumpeter and laugher, as their names express, utter a very different coo from the other breeds. The fantail has thirty or even forty tailfeathers, instead of twelve or fourteen, the normal number in all members of the great pigeon family; and these feathers are kept expanded, and are carried so erect that in good birds the head and tail touch ; the oil-gland is quite aborted. Several other less distinct breeds might have been specified." " In the skeletons of the several breeds, the development of the bones of the face in length and breadth and curvature differs en- ormously. The shape, as well as the breadth and length of the ramus of the lower jaw, varies in a highly remarkable manner. The number of the caudal and sacral vertebrae vary ; as does the number of the ribs, together with their relative breadth and the presence of processes. The size and shape of the apertures in the sternum are highly variable ; so is the degree of divergence and relative size of the two arms of the furcula. The proportional width of the gape of mouth, the proportional length of the eye- lids, of the orifice of the nostrils, of the tongue (not always in strict correlation with the length of beak), the size of the crop and of the upper part of the oesophagus : the development and abortion of the oil-gland ; the number of the primary wing and caudal feathers; the relative length of wing and tail to each other and to the body ; the relative length of leg and of the feet ; the number of scutellae on the toes, the development of skin between the toes, are all points of structure which are variable** The period at which the perfect plumage is acquired varies, as does the state of the down with which the nestling birds are On the Origin of Sjpecies, 105 clothed -when hatched. The shape and size of the eggs vary. The manner of flight difl'ers remarkably ; as does in some breeds the voice and disposition. Lastly, in certain breeds, the males and females have come to differ to a slight degree from each other." " Altogether at least a score of pigeons might be chosen, which if shown to an ornithologist, and he were told that they were wild birds, would certainly, I think, be ranked by him as well-defined species. Moreover, I do not believe that any ornithologist would place the English carrier, the short-faced tumbler, the runt, the barb, pouter, and fantail in the same genus ; more especially as in each of these breeds several truly-inherited sub-breeds, or species as he might have called them, could be shown him." " Great as the differences are between the breeds of pigeons, I am fully convinced that the common opinion of naturalists is correct, namely, that all have descended from the rock-pigeon (Columba livia), including under this term several geographical races or sub-species, which differ from each other in the most trifling re- spects. As several of the reasons which have led me to this be- lief are in some degree applicable in other cases, I will here briefly give them. If the several breeds are not varieties, and have not proceeded from the rock-pigeon, they must have des- cended from at least seven or eight aboriginal stocks ; for it is impossible to make the present domestic breeds by the crossing of any lesser number : how, for instance, could a pouter be produc- ed by crossing two breeds unless one of the parent-stock possessed the characteristic enormous crop? The supposed aboriginal stocks must all have been rock-pigeons, that is, not breeding or willingly perching on trees. But besides C. livia, with its geo- graphical sub-species, only two or three other species of rock- pigeons are known ; and these have not any of the characters of the domestic breeds. Hence the supposed aboriginal stocks must either still exist in the countries where they were originally do- mesticated, and yet be unknown to ornithologists ; and this, con- sidering their size, habits, and remarkable characters, seems very improbable; or they must have become extinct in the wild state. But birds breeding on precipices, and good fliers, are unlikely to be exterminated ; and the common rock-pigeon, which has the same habits with the domestic breeds, has not been exterminated even on several of the smaller British islets, or on the shores of the Mediterranean. Hence the supposed extermination of so many species having similar habits with the rock-pigeon seems to 106 Review of Darwin me a very rash assumption. Moreover, the several above-named domesticated breeds have been transported to all parts of the world, and, therefore, some of them must have been carried back again into their native country ; but not one has ever become wild or feral, though the dovecot-pigeon, which is the rock-pigeon in a very slightly altered state, has become feral in several places. Again, all recent experience shows that it is most diflficult to get any wild animal to breed freely under domestication ; yet on the hypothesis of the multiple origin of our pigeons, it must be as- sumed that at least seven or eight species were so thoroughly do- mesticated in ancient times by half-civilized man, as to be quite prolific under confinement." " An argument, as it seems to me, of great weight, and applicable jn several other cases, is, that the above-specified breeds, though agreeing generally in constitution, habits, voice, colouring, and in most parts of their structure, with the wild rock-pigeon, yet are certainly highly abnormal in other parts of their structure : we may look in vain throughout the whole great family of Colum- bidse for a beak like that of the English carrier, or that of the short-faced tumbler, or barb ; for reversed feathers like those of the jacobin ; for a crop like that of the pouter; for tail-feathers like those of the fan-tail. Hence it must be assumed not only that half-civilized man succeeded in thoroughly domesticating seve- ral species, but that he intentionally or by chance picked out ex- traordinarily abnormal species ; and further, that these very species have since all become extinct or unknown. So many strange contingencies seem to me improbable in the highest de- gree." " Some facts in regard to the colouring of pigeons well deserve consideration. The rock-pigeon is of a slaty-blue, and has a white rump (the Indian sub-species, C. intermedia of Strickland, having it bluish) ; the tail has a terminal dark bar, with the bases of the outer feathers externally edged with white ; the wings have two black bars ; some semi-domestic breeds and some ap- parently truly wild breeds have, besides the two black bars, the wings chequered with black. These several marks do not occur together in any other species of the whole family." " Now, in every one of the domestic breeds, taking thoroughly well-bred birds, all the above marks, even to the white edging of the outer tail-feathers, sometimes concur perfectly developed* Moreover, when two birds belonging to two distinct breeds are On the Origin of Species, 107 crossed, neither of which is blue or has any of the above-specified marks, the mongrel offspring are very apt suddenly to acquire these characters ; for instance, I crossed some uniformly white fantails with some uniformly black barbs, and they produced mottled brown and black birds ; these I again crossed together, and one grandchild of the pure white fantail and pure black barb was of as beautiful a blue colour, with the white rump, double black wing-bar, and barred with white-edged tail-feathers, as any wild rock-pigeon. We can understand these facts, on the well- known principle of reversion to ancestral characters, if all the domestic breeds have descended from the rock- pigeon. But if we deny this, we must make one of the two following highly impro- bable suppositions. Either, firstly, that all the several imagined aboriginal stocks were coloured, and marked like the rock-pigeon, although no other existing species is thus coloured and marked, so that in each separate breed there might be a tendency to re- vert to the very same colours and markings. Or, secondly, that each breed, even the purest, has within a dozen or, at most, with- in a score of generations, been crossed by the rock pigeon : I say within a dozen or twenty generations, for we know of no fact countenancing the belief that the child ever reverts to some one an- cestor, removed by a greater number of generations. In a breed which has been crossed only once with some distinct breed, the tendency to reversion to any character derived from such cross will naturally become less and less, as in each succeeding genera- tion there will be less of the foreign blood ; but when there has been no cross within a distinct breed, and there is a tendency in both parents to revert to a character, which has been lost during some former generation, this tendency, for all that we can see to the contrary, may be transmitted undiminished for an indefinite number of generations. These two distinct cases are often con- founded in treatises on inheritance." " Lastly, the hybrids or mongrels from between all the domestic breeds of pigeons are perfectly fertile. I can state this from my own observations, purposely made on the most distinct breeds. Now, it is difficult, perhaps impossible, to bring forward one case of the hybrid offspring of two animals clearly/ distinct being themselves perfectly fertile. Some authors believe that long-con- tinued domestication eliminates this strong tendency to sterility: from the history of the dog I think there is some probability in this hypothesis if applied to species closely related together, 1 08 Review of Darwin though it is unsupported by a single experiment. But to extend the hypothesis so far as to suppose that species, aboriginally as distinct as carriers, tumblers, pouters, and fantails now are, should yield offspring perfectly fertile, inter se, seems to me rash in the extreme." *^ From these several reasons, namel}^, the improbability of man having formerly got seven or eight supposed species of pigeons to breed freely under domestication ; these supposed species being quite unknown in a wild state, and their becoming nowhere feral ; these species having very abnormal characters in certain respects as compared with all other Columbidse, though so like in most other respects to the rock-pigeon ; the blue colour and various marks occasionally appearing in all the breeds, both when kept pure and when crossed ; the mongrel offspring being perfectly fertile ; — from these several reasons, taken together, I can feel no doubt that all our domestic breeds have descended from the Ooluinha livia with its geographical sub-species." "In favour of this view, I may add, firstly, that C. livia, or the rock-pigeon, has been found capable of domestication in Europe and in India ; and that it agrees in habits and in a great number of points of structure with all the domestic breeds. Secondly, although an English carrier or short-faced tumbler differs im- mensely in certain characters from the rock-pigeon, yet by com- paring the several sub-breeds of these breeds, more especially those brought from distant countries, we can make an almost per- fect series between the extremes of structure. Thirdly, those characters which are mainly distinctive of each breed, for in- stance the wattle and length of beak of the carrier, the shortness of that of the tumbler, and the number of tail-feathers in the fan- tail, are in each breed eminently variable ; and the explanation of this fact will be obvious when we come to treat of selection. Fourthly, pigeons have been watched, and tended with the utmost care, and loved by many people. They have been domesticated for thousands of years in several quarters of the world ; the ear- liest known record of pigeons is in the fifth ^Egyptian dynasty about 3000 b. c. as was pointed out to me by Professor Lepsius ; but Mr. Birch informs me that pigeons are given in a bill of fare in the previous dynasty. In the time of the Romans, as we hear from Pliny, immense prices were given for pigeons ; " nay, they are come to this pass, that they can reckon up their pedigree and race." Pigeons were much valued by Akber Kban in India* On the Origin of Sjjecies, 109 about the year 1600 ; never less than 20,000 pigeons were taken with the court. " The inonarchs of Iran aad Turan sent him some very rare birds ;" and, continues the courtly historian, '' His Majesty, by crossing the breeds, which method was never prac- tised before, has improved them astonishingly." About this same period the Dutch were as eager about pigeons as were the old Romans. The paramount importance of these considerations in explaining the immense amount of variation which pigeons have undergone, will be obvious when we treat of Selection. "We shall then, also, see how it is that the breeds so often have a somewhat monstrous character. It is also a most favourable circumstance for the production of distinct breeds, that male and female pigeons can be easily mated for life ; and thus different breeds can be kept together in the same aviary." The common rock-pigeon is thus proved to be highly variable in a state of domestication, so much so that naturalists not aware of all the facts, might well be excused for concluding, as some of them have done in the similar instances of the ox, the domestic fowl, and man himself, that the varieties represent several distinct species. To what then do these diflerences amount ? (1) They are mainly in non-essential points, as colour, development o^ feather, etc., and they do not consequently interfere, to any impor- tant extent, with the food and habits of the animal ; or if we were to represent the matter from the opposite point of view to that taken by Mr. Darwin, the constitution and instincts of the species being fixed by the law of its creation, it cannot vary be- yond these. The author is clearly wrong in stating that any of them could amount to generic distinctions; that is, if genera are to be based on structural differences, for of these there is compa- ratively little, except in the one point of proportion of parts, difter- ence in which is of specific value only, and often occurs in near varieties. (2) Many of the differences are abnormal ; that is, they are of the character of monstrosities, and this separates them widely from true specific diflerences. (3) The varieties are per- fectly fertile, which is not the case with hybrids between clearly distinct species. (4) The cross breeds revert to the characters of the rock-pigeon, showing that the specific type still remains uneradicated, or that each variety is, so to speak, a hemitropic form, which, when united with an opposite one, tends to reproduce the original form. It follows from these results, that, however 110 Review of Darwin likely to be mistaken for species, the varieties of the pigeon are really something essentially different from true species, and the same conclusion would hold with any animal that could be selected. We now come to the causes of variation in a state of domesti- cation ; and here, already, in the twenty-ninth page of his volume, we find our author leaving the basis of fact and losing himself in the mazes in which he henceforth continues to wander. He attributes the varieties of domestic animals to "Man's power of accumulative selection ; nature gives successive variations ; man adds them up in certain directions useful to him." We object to this, as altogether a partial and imperfect statement. It is not nature that gives the variations, but external circumstances; while nature only gives a certain capacity to vary, the extent of which is the point in question. Man places animals in abnormal conditions into which their instincts and natural powers would not permit them of themselves to enter. They vary in conse- quence of these, sometimes suddenly, sometimes gradually, some- times from premeditated treatment, sometimes unaccountably, sometimes in directions useful to man, sometimes the reverse. Out of all the diversities thus produced, man no doubt selects Avhat suits him, and keeps it, as far as he can, in the conditions favorable to its permanence and improvement ; but such selection is a comparatively small part of the actual cause of the pheno- mena observed, which result really from unnatural conditions of life compelled by man. Who selected, for example, the niata cattle of South America, the hairless dogs of Chili, the tail-less cats of the Isle of Man, and many other forms ? Selection is no doubt an important cause of the continuation and improvement of varieties, and has also, as our author main- tains, been practised from a very remote antiquity in the case of the more valuable domesticated animals. He might have referred to a more ancient case than any of those he has noticed. Laban selected all the speckled cattle from Jacob's flock, understanding very well the principle of selection ; but Jacob was better informed than Laban or Mr. Darwin, and not trusting to selection, but knowing the effect of external influences and their special impor- tance in the embryonic state, he set up peeled twigs before the pregnant cattle, and so acting on the embryo through the senses of the mother, produced the':variety he desired. The undue pro- minence given to selection by our author is the main basis on which he subsequently proceeds. Oil the Origin of Species, lit His next step is to establish analogies between variation and specific difference, as observed in nature. Many species are doubtful ; that is, naturalists are not quite decided that they may not be varieties. This is true ; but such species are the excep- tions, and the differences of view have arisen as much from defec- tive observation or reasoning as from any real difficulty. Again, in large genera the species approach each other very nearly. This is inevitable^from the nature of the case, and though it may cause difficulties in distinguishing them, it proves nothing as to their not being true species. Species which range "widely also are prone to vary, and this also follows from the nature of the case, great range and much variability being really cause and effect, and reacting on each other. Farther, it is stated that species belonging to large genera are more prone to vary than species belonging to small genera. This has not been established as a general principle, nor, if it should be, would it necessarily bear the interpretation put upon it. To reach the facts we must be certain that we are comparing natural genera consisting of species having true affinities of structure, and that all our generic dis- tinctions are based on the same grades of difference. Further, we must make separate lists of the genera small now but large if we take all geological time, as for instance the genus Lingular of genera small in any particular country, but large if the whole world be taken ; and lastly, of genera large in some particular region or country. This last is the only case which can fairly test Mr. Darwin's principle, and we must say that in our limited experience there appear to be quite as many exceptions as agree- ments with the rule. Take, for instance, the genera SoUdago and Aster among American plants, which, thoi^gh growing together in numerous species, are not remarkably variable. Further, when a generic type has proved suitable to occupy many places in a particular country, it may well be that many of its species will be capable of a wide range, and so variable. For such reasons we hold that the attempt made on the ground of analogies be- tween the species and the variety to break down the distinction between them signally fails. But if the reader is willing to take this for granted, Mr. Darwin will carry him a step further. He next proceeds to maintain that in nature there is a power of selection similar to that which the breeder exercises — a power of " Natural Selection " not heretofore recog- nised, and by virtue of which varieties are produced and developed 112 Review of Darwin into species. There is here a huge hiatus in the reasoning of our author. We have already shown that an excessive import- ance is attributed to artijScial or human selection ; but with all the exaggeration of its powers, it has proved insufficient to change one species into another. The pigeon, with all its varieties, is still a pigeon, and, according to our author's own conclusive argu- mentation, a rock-pigeon. It is not a wood-pigeon, or turtledove, still less a partridge or a rook. But now we are asked to believe that those same natural courses which break down all th« breeder's elaborate distinctions so soon as his^breeds are allowed to intermix and live in a natural way, are themselves able to take up the work and do still greater marvels in the way of selection. Such a doc- trine is self-contradictory, and, we believe wholly incapable of proof; but let us see how this is attempted : As might have been anticipated, natural selection being either creation or nothing, a new power is evoked as B,^primum mobile. This is the " struggle for existence," a fancied warfare in nature, in which the race is always to the swift and the battle to the strong, and in which the struggle makes the strong stronger. In a pre- vious chapter we have been told very truly that the reason why the wealthy and skilful breeder succeeds in producing marked races is that his animals are cared for and pampered, while the savage and the poor man fail because their animals must struggle for subsistence. Nature it appears takes the opposite way, and improves her breeds by putting them through a course of toil and starvation, a struggle not for happiness or subsistence, but for bare existence. We can understand how this should deteriorate and degrade species, as we know it has done in every case of the kind that we have observed ; but how it should elevate or improve is past comprehension. But does nature deserve to be charged with such niggardliness, and with so concealing it that all the world seems to be full of happiness and plenty, except where poor man toils on in his poverty ? In looking for the proof of this strange doctrine, we find stated in support of it only a number of isolated and exceptional facts, many of them cases in which man inter- feres with the equilibrium of nature ; and we have to fall back on the general statement that the struggle for existence inevitably fol lows from the high rate at which organic beings tend to increase but this Malthusian doctrine, though good for a single species viewed by itself, is false for the whole in the aggregate. Vege- table life and the lower forms of animal life support the higher, 0)1 the Origin of Species. 113 and these supporting forms increase far more rapidly tlian those that subsist on them. So much so, that vast quantities of organic food go to waste, or would do so but for the hordes of scavengers of low organization that seem specially created to gather up the frao^ments of nature's bounteous feast. Plant life thrives on the exhaustless stores of inorganic food provided for it by the soil and the atmosphere. Plant life supports animal life ; but who ever saw the floor of the ocean denuded of its algae, or the landscape bared of its verdure by the struggle of feeders for existence, except in a rare and exceptional case, as in a flight of locusts ? There is always enough and to spare. Again, do the insects fail or become scarce under the ceaseless attacks of the insectivorous birds ? Do not Clios and Salpas and coral polyps abound almost as much as if not preyed on by countless fishes and other animals ? The beautiful harmony of nature provides that the feeders shall multiply more slowly than the food, and that the food shall be kept under by the feeders. When any form does locally multiply too far, the checks appear, usually in the form of a diminished reproduction or in the more rapid removal of the infirm, the sickly and the aged. When through the slow operation of physical causes or the introduction of new species, certain forms of life can no longer find the means of subsistence, all the facts we know indicate their disappearance, not their change into new forms. Nay, species verging to extinction or struggling for existence, like the red deer of Scotland, degene- rate rather than improve, and must necessarily do so, so long as the laws of organic being remain what they are. In short, the struggle for existence is a myth, and its employment as a means of improvement still more mythical. Were we bound to argue for such a thesis as that proposed by Mr. Darwin, we should much rather take up our ground on the improvement of the physical conditions of the earth, and maintain that each species finding its means of subsistence and happiness constantly extending, exerted itself for their occupancy, and so developed new powers. This would have the advantage of giving a more agreeable view of nature, and of accounting for elevation ; as if nature, like a skilful breeder, were giving constantly better food or pasture, instead of imitating the luckless experimenter who strove to reduce the daUy food of the horse to a single straw. The remarks that we have made on natural selection, and the struggle for existence, afford a key to the whole of Mr. Darwin's argument, which amounts to little else than a wholesale appropria Can. Nat. 3 Vol . V. N o 114 Review of Darwin tion of all the effects of external conditions of existence to these supposed causes of change. We could fill pages with evidence of the entire confusion of ideas which pervades his mind on this point, but one extract must suffice, both as an indication of this confusion, and as a fair example of the argument : " How much direct effect difference of climate, food, &c., pro- duces on any being is extremely doubtful. My impression is that the effect is extremely small in the case of animals, but perhaps rather more in that of plants. We may, at least, safely conclude that such influences cannot have produced the many striking and complex co-adaptations of structure between one organic being and another, which we see everywhere throughout nature. Some little influence may be attributed to climate, food, &c. : thus, E. Forbes speaks confidently that shells at their southern limit, and when living in shallow water, are more brightly coloured than those of the same species further north or from greater depths. Gould believes that birds of the same species are more brightly coloured under a clear atmosphere, than vs^hen living on islands or near the coast. So with insects^ Wollaston is convinced that residence near the sea affects their colours. Moquin-Tandon gives a list of plants which when gTowing near the sea-shore have their leaves in some degree fleshy, though not elsewhere fleshy. Se- veral other such cases could be given." " The fact of varieties of one species, when they range into the zone of habitation of other species, often acquiring in a very slight degree some of the characters of such species, accords with our view that species of all kinds are only well-marked and perma- nent varieties. Thus the species of shells which are confined to tropical and shallow seas are generally brighter coloured than those confined to cold and deeper seas. The birds which are con- fined to continents are according to Mr. Gould, brighter coloured than those of islands. The insect species confined to &ea-coast&, as every collector knows, are often brassy or lurid. Plants which live exclusively on the sea-side are very apt to have fleshy leaves. He who believes in the creation of each species, will have to say that this shell, for instance, was created with bright colours for a warm sea ; but that this other shell became bright coloured by variation when it rano^ed into warmer or shallower waters," " When a variation is of the slightest use to a being, we cannot tell how much of it to attribute to the accumulative action of natural selection, and how much to the conditions of life. Thus, On the Origin of Species* 115 it is well known to furriers that animals of the same species have thicker and better fur the more severe the climate is under which they have lived ; but who can tell how much of this difference may be due to the warmest-clad individuals having been favoured and preserved during many generations, and how much to the direct action of the severe climate ? for it would appear that cli- mate has some direct action on the hair of our domestic qua- drupeds." "Instances could be given of the same variety being produced under conditions of life as different as can well be conceived ; and, on the other hand, of different varieties being produced from the same species under the same conditions. Such facts show kow indirectly the conditions of life must act. Again, innume- rable instances are known to every naturalist of species keeping true, or not varying at all, although living under the most opposite climates. Such considerations as these incline me to lay very little wei2:ht on the direct action of the conditions of life. In- directly, as already remarked, they seem to play an important part in affecting the reproductive system, and in thus inducing variability ; and natural selection will then accumulate all profi- table variations, however slight, until they become plainly deve- loped and appreciable by us." It would be possible to fill up the remainder of our space with the objections we have to the statements in these few paragraphs. The scepticism as to the effects of food, climate, &c., in producing variation, and the effects attributable to a supposed selecting power which can merely act on such changes when previously induced ; the failure to perceive that the adaptation of certain species to certain conditions of life necessarily implies that if other species not so adapted migrate within the influence of the conditions, they must, so far as their natures permit, be influenced by them ; that in short such variation vindicates the wisdom of the Creator while showing that the plasticity of species may simulate in a humble way specific distinctness ; the feeble attempt to attribute the warm fur of northern varieties to selection, while manifestly unable to deny that climatic influence is the main cause ; these are specimens of a style of thought which pervades the whole book, and which leaves the task of a reviewer hopeless, for it would require a book as large as the original to expose the fallacies which appear in every paragraph. In one respect Mr. Darwin vindicates fully his well-earned 116 Review of Darwin reputation as a scientific naturalist. He fairly and ably states the many objections to his view that must occur to the minds of zool- ogists, botanists and geologists, and manfully, though unsuccess- fully, attempts to cope with them. Such objections are, the geographical distribution of the crea- tures supposed in Mr. Darwin's view to be nearly related by descent, the want of the innumerable transitional forms that should exist, the difficulty of accounting for the peculiar instincts of many animals, the sterility of first crosses and hybrids compared with the fertility of crosses of varieties, the want of any trace of unlimi- ted variation in the geological succession of animals. We shall only refer to the last of these, the geological objec- tion. Geology he admits shews no trace of the " finely graduated organic chain " which in his theory should connect man with the extinct kangaroo-rat-like marsupials of the oolite and trias, and all our existing animals and plants with the perished creatures supposed to be their progenitors. He has but one explanation of this, the "extreme imperfection of the ■ geological records." To illustrate this imperfection, he refers to the immense lapse of time involved in the geological record, to the small number of species known compared with this great lapse of time, to the breaks caused by the absence of fossiliferous deposits at certain periods. All these are fair abatements from the completeness of the geological series, and many of the remarks made on them are very valuable ; but they do not mitigate the condemnation of the selection theory pronounced by geology. Breaks in the geological record are usually only local, and if general, might indicate actual destruction and renewal of species. Though it is true that estuary and land deposits have in most cases been preserved only in times of subsidence ; this is not true of marine deposits, some of the most perfect of which mark times of elevation. Moreover, in those parts of the geological scale which are the most perfect and unbroken, there is no graduated transition of forms. Take for instance the great Silurian limestones of America, or the plant-bearing beds of the coal formation. In both we find some species perseveringly unchanged through many great deposits, and others suddenly appearing and disappearing, and this in cases where the profusion of specimens and continuity of formations preclude any supposition of much imperfection in the evidence. Nothing is more conclusive on this subject than the last of the fossiliferous deposits, next to the modern period ; as, for instance, the Post-Pliocene clays and 071 the Origin of SjJecies, 117 sands of Canada. These belong to a period of elevation proceed- ing gradually from tlie time of the boulder formation up to the modern era. In these deposits we have more than stxty species of invertebrate animals, all except one or two known to be now living in the Gulf of St. Lawrence. Yet in all thia lapse of time not one of the species has, by natural selection or any other cause, varied more than its living relatives now do. Still further, one or two species, as the Leda truncata and Triclwtropis arctlca, now found only in the Arctic seas, are quite like their modern representatives in those distant waters. They had plenty of time to vary, in order to suit the new circumstances, but they could not. Further, at the same time when these shells lived in the plains of Canada, Arctic plants, conveyed probably by ice, became settled on the White Mountains, the descendants of which still remain isolated but unchanged. Such facts as these are conclusive, notwithstand- ing the imperfection of the geological record on other points. In one point our author endeavors to find support to his views from geological evidence, in the resemblance of successive faunas of the same locality to each other. The extinct ter- tiary animals of South America, New Zealand and Australia, for example, are like in type to those now inhabiting the same regions. But then we have no connecting links, and hence it seems more probable that successive creations were conformed to the same generic types, because the physical conditions remained unchanged, than that the modern sloths, for example, are degene- rate descendants of the Megatheria. Farther, it does not seem to have occurred to Mr. Darwin that these resemblances are confined to the southern hemisphere. They do not obtain at all in North America, in Northern Asia, in Europe. In these coun- tries new types have replaced the old, and certain old species, like the musk ox, the megaceros, the beaver, the aurochs, have become locally or wholly extinct, instead of undergoing change. All this has happened no doubt because the modern conditions are too dissimilar from the ancient to permit the con- tinuance of old forms under any variety of them, and thus new forms have been introduced. In his closing chapters the author endeavours to shew that his theory accounts in a satisfactory manner for the typical likeness of species to each other, for the curious embryological relations of animals, and for the existence of rudimentary organs ; but all these things are equally intelligible on the opposite view. If spe- 118 Review of Darwin cies are parts of a plan devised by an intelligent Creator, that plan must appear in their structures. If the plan embraces more general and more specialised contrivances, the latter must, in their earlier stages of growth, simulate the former. All organs, if there is a plan at all, must appear in its different parts in different degrees of relative perfection and complexity, and what we call rudimentary organs are merely the lowest of these de- grees ; not useless, for in many cases we know their uses, but of less relative importance than in other cases. We have in the foregoing remarks dwelt chiefly on the points in which we believe the author to be mistaken ; but we do not wish to undervalue the work. In many respects it is eminently useful. It shews, in opposition to many views maintained with much vigour on this side of the Atlantic, the great variability of species. It imposes a salutary caution on those naturalists who too readily admit geographical distribution as an evidence of specific distinctness. It illustrates by a vast fund of curious fact the obscure laws of variation and hybridity. All these pearls are not the less valuable to the judicious reader, that the author has seen fit to string them upon a thread of loose and faulty argu- ment, and to employ them to deck the faded form of the trans- mutation theory of Lamarck. In conclusion, it is but fair to state in his own words the ulti- mate deductions of the author, and then the opposite view, as maintained by the greater number of naturalists : — - *' It may be asked how far I extend the doctrine of the modi- fication of species. The question is difficult to answer, because the more distinct the forms are which we may consider, by so much the arguments fall away in force. But some arguments of the greatest weight extend very far. All the members of whole classes can be connected together by chains of affinities, and all can be classified on the same principle, in groups subordinate to groups. Fossil remains sometimes tend to fill up very wide inter- vals between existing orders. Organs in a rudimentary condition plainly show that an early progenitor had the organ in a fully developed state ; and this in some instances necessarily implies an enormous amount of modification in the descendants. Through- out whole classes various structures are formed on the same pat- tern, and at an embryonic age the species closely resemble each other. Therefore I cannot -^'doubt that the theory of descent with modification embraces all the members of the same class. On the Origin of Species, 119 I believe tliat animals have descended from at most only four or five progenitors, and plants from an equal or lesser number. " Analogy would lead me one step further, namely, to the belief that all animals and plants have descended from some one prototype. But analogy may be a deceitful guide. Neverthe- less all living things have much in common, in their chemical composition, their germinal vesicles, their cellular structure, and their laws of growth and reproduction. We see this even in so trifling a circumstance as that the same poison often similarly affects plants and animals ; or that the poison secreted by the gall-fly produces monstrous growths on the wild rose or oak-tree. Therefore I should infer from analogy that probably all the or- ganic beings which have ever lived on this earth have descended from some one primordial form, into which life was first breathed." We may well ask what is gained by such a result, even if established. The origin of species, as we now have them, it is true is mysterious, but what is gained by reducing them all to one primitive form ? That would be an equal mystery, more especially if it included within itself the germs of all the varied developments of animal and plant life. By such a doctrine also we involve ourselves in a host of geological and other difiiculties, and so break down the distinction between species and varieties as to deprive our classifications of any real value. On the con- trary, if we are content to take species as direct products of a creative power, without troubling ourselves with supposed secon- dary causes, we may examine, free of any trammelling hypothesis, the law of their succession in time, the guards placed upon their intermixture, the limits set to their variation in each case, the remarkable arrangements for diminishing variations by the natural crossing of varieties, the laws of geographical distribution from centres of origin, and the physical causes of variation, of degene- racy, of extinction. All these are questions to be investigated apart from any hypo- thesis of the common origin of different species on the one hand, or of the diverse origin of individuals apparently identical on the other ; and we cannot doubt that the results will approach to the following conclusions. (1) That the origin of specific distinctness lies beyond the domain of any natural law known to us. (2) That the variations of the species are the effects of the combined influences of its natural endowments and of external circumstances. (3) That 120 Sketch of the Life of Mr. David Douglas, in nature specific force and causes of variation constitute antago- nist powers, acting and reacting on each other, and thus produc- ing an equilibrium which is disturbed only by the artificial contri- vance of man. We are quite certain that the belief of naturalists in these great doctrines will eventually be confirmed by Mr. Dar- win's book, and that his failure, with all the immense mass of facts at his disposal, to maintain the theory of transmutation, will give an eternal quietus to the Lamarckian hypothesis ; though we shall be quite prepared to find that for a time it may gain a wide acceptance with young naturalists, and with those who are willing to adopt any amount of error rather than appear not to be on a level with the latest scientific novelties. For this signal service to science we sincerely thank him, though we are sorry that it has been rendered by a man whose sincerity and honesty of purpose all who know him respect and love, and to whom .natural science is under so many eminent obligations. Since writinir the above, we have seen able reviews of Mr. Dar- win's work by Prof. Gray and Prof. Huxley. Both naturalists dissent from his ultimate conclusions as not satisfactorily proved,, though neither, in our view, insists sufficiently on the fundamen- tal unsoundness of the argument. J. W. D. ARTICLE ^.—Abridged Sketch of the life of 3Ir. David Douglas, Botanist, with a few details of his travels and discoveries. The inducement for collecting the few scattered fragments that are to be found in the following pages, is the desire to prolong somewhat, the public remembrance of one who was warmly at- tached to Natural History, and who also in his own short day^ largely contributed by his enterprise and unwearied spirit of re- search, to swell the list of novelties in some of its principal de- partments. Cut down in the prime of life, and in the midst of his usefulness, his memory is still fondly cherished by his friends, and his successful exertions in his sphere of labour have pro- cured him among botanists, an undying fame. Had he lived, he would have attained to the highest celebrity as a traveller, for his diligence in investigating, and accuracy in observing, would" have tended to elucidate much that is of ereat interest in the? physical geography of the earth. Slietch of the Life of Mr. David Douglas. 121 David Douglas, of humble but respectable parentage, was born at Scoone in Perthshire in the last year of the last century. He received his early education at the parish school of Kinnoul, in the neighbourhood. He was somewhat wayward, and therefore frequently the mark for the master's ire. Trout-fishing and bird-nesting held out temptations too strong for the lively boy, and such occupations often lengthened his road, if they did not entirely prevent his march to school. His love of nature soon displayed itself in the rearing of birds, collecting of plants, and other such amusements. Following up these early intuitions, employment was found) for him, first in the nursery ground and then in the gardens of the Earl of Mansfield, at Stowe. Here his zeal and industry were so conspicuous, that they gained him the esteem and affection of the superintendent. After a seven years apprenticeship in these gardens, where he acquired a thorough knowledge of the practical part of gardening, the friend- ship of the superintendent Mr. Beatty, procured him a situa- tion under Mr. Alexander Stewart, who had charge of the gardens at Valleyfield, the seat of Sir Kobert Preston near Culross. There being at this place a very choice collection of plants, the attrac- tions of the kitchen-garden and of out-door work, soon lost their weight with young Douglas, who now began to study botany, and to attach himself to the care of the exotics, of which Valley- field could boast a magnificent display. Being very careful of the plants committed to his care, Mr. Stewart showed him much kind- ness, and allowed him the privilege and advantage of Sir Robert's botanical library. Such an opportunity was not lost by the youth- ful naturalist. The second year he became foreman to Mr. Stewart, when upon application, he gained admission to the Botanical gar- dens at Glasgow. This nursery of botanists was still in its in- fancy, but advancing rapidly to high reputation under the know- ledge, skill, and fostering influence of Professor Hooker, since whose time, a succession of able and indefatigable Botanists have well preserved its celebrity. The energetic working qualities of Douglas, and his vivacity of disposition, speedily procured him the esteem and regard of all connected with the gardens ; and the valuable friendship of the professor, which he at this time acquired, may be looked upon as the reward of his sterling merits. For the Professor, now Sir W. Jackson Hooker, I have heard him express such sentiments as a son mis-ht hold for a revered and beloved parent. First a diligent attendant at the botanical lectures, 122 Sketch of the Life of Mr, David Douglas. next a favourite companion of the professor during his periodi- eal excursions through the Highlands of Scotland, his capacity was quickly recognised hy the keen judgment of Hooker, and the noble qualities of his mind pointed him out as one from whom much might be expected. Douglas was afterwards recommended as botanical collector to the London Horticultural Society, for which he was indebted to Sir William, as well as to Mr. Stewart, Nursery Curator of the Glasgow Botanic Grardens, who always took a lively interest in his welfare. The recommendation was attended to, and the first appointment made out for the young botanist was to the United States. In the summer of 1823, he there procured many fine plants for the Society and added greatly to its collection of fruit trees. Pleased with his exertions, the Horticultural Society, thought of a wider field for their new collector, and the interior of North West America being a region yet unexplored by any naturalist, they wisely determined upon availing themselves of Douglas's youthful vigour and talents in that quarter. Joseph Sabine Esquire, then Honorary Secretary to the Society, took the most friendly notice of Douglas, and was also highly interested in the success of his mis- sion, and the then Governor or Deputy-Governor of the Hudson's Bay Company, afibrded every kind assistance, and such valuable information towards the prosecution of his labors, as to insure liappy results. The 25th of July 1824, found our scientific adventurer on board the Hudson Bay Company's ship William and Anne, fortunate in having the companionship of Dr. Scouler of Glasgow, a younger man than himself, but ardently devoted to everything pertaining to natural history. An extract from the sketch of his life taken from a London botanical periodical, will give some idea of the style in which Douglas recorded his observations on living nature. After crossing the tropics, he wi'ites thus of the Albatross. " While within the paralells of 50° and 60^^, I caught sixty-nine ^' specimens of JDiomeda, consisting of D. exulaus^fulginosa, and '' chlororynclios. The last, though a smaller bird than the first, " reigns lord paramount over the rest, and compels them all to flee " at his approach. It is stated by most authors that these birds '* are taken with the greatest ease during warm weather ; it was " only during the driving gusts of a storm that I could secure them, " and on such occasions they fight voraciously about the bait, the " hook often being received into the stomach. The appearance of STcetch of the Life oj Mr* David Douglas, 123 " these birds is grand and majestic ; the largest which I ever saw, " measured twelve feet four inches from tip to tip of the extended " wings, and four feet from the point of the beak to the end of the " tail. As respects their flight, the same renarks apply to all the " species. When sitting on the water their wings are raised ex- " actly like a swan's ; when feeding they are somewhat higher, with " a constant tremulous motion like those of the hawk tribe ; and " when elevating themselves in the water to soar in the air, they " first walk the water, skimming the surface with the points of " their pinions for the distance of several hundred yards, before " they seem able to raise themselves, which they generally do with " the utmost grace, and with scarcely any apparent movement of " their wings. They are of a bold and savage disposition, which *' is especially displayed when they are captured." At the island of Juan Fernandez he fell in with a poor sailor, named William Clarke, who had employment from the Spaniards who visit this place for the purpose of killing seals and wild cattle, which were plentiful. Near the remains of an old church once built there, Douglas writes " there is a circular oven, built of London " fire-brick, seven feet in diameter within, bearing the date 1741, '' and therefore probably built by Anson during his residence." " Some pigeons of a small blue species, now occupy it as their " cote. There were eggs in it but no young ones. I pointed it out " to Clarke, and advised him to make use of this colony." In the old gardens were found peaches of three or four sorts, quinces, apples, and pears ; figs and vines were also in a thriving state. Before leavins:, Dousrlas left with Clarke, the seeds of some culinary vegetables, radishes being the only article of that kind that appeared to be on the island. Douglas's eye was alive to all that is picturesque, and his glowing description of that en- chanting spot, is thus given with the spirit of a botanist. ^' No pen, indeed, can correctly describe the charming and rural " appearance of this island ; the numerous rills descending through " valleys overshadowed by luxuriant verdure, and terminating in " dark recesses and rocky dells, where wave the fronds of Xoma^ia, " Aspidia and Polypodia, several species of which are new and of " princely form and growth. On the hills grow several kinds of *' JEscallonia, BerheriSj Lobelia^ Hordeum, and Avena. During " my short stay, I gathered seventy distinct and highly interesting " plants. The species of birds were few and not beautiful." Arrived at the Gallipagos, Mr. Douglas was on shore on one of 124 Sketch of the Life of Mr. David Douglas, that group, named James island, from which he drew a fair collec- tion of both birds and plants, nearly all of which were lost to him in consequence of the dampness of the vessel below, and the inces- . sant rains upon deck. Of one hundred and seventy-five species of plants gathered, he saved but fifty, and of birds, one only remained to him of the forty-five he had killed. This was but an earnest of the still heavier losses he afterwards sustained in his collections. He says of the Gallipagos : — " Their verdure is scanty as com- ' pared with most tropical countries, owing apparently to the ' parched nature of the soil, and the absence of springs of fresh ' water. The only spring I saw, was flowing from a crevice of one ' of the craters. Some of the trees attain a considerable size in the ' valleys, but they are not numerous, and with little variety of ' species. The birds, however, are abundant, and some of them ' exceedingly handsome, but so ignorant were they of man's de- ' vices, that they sufiered themselves to be killed with a stick, so ' that a gun was only needed when they sat high on the top of a ' tree or rock. Many of the small birds perched on my hat, and ' even unconsciously settled upon the gun (the instrument of ' their destruction,) which I carried on my shoulder." One may form an idea of the difficulty of entering the Colum- bia river in the winter season, from the fact that the AVilliam and Anne was obliged to lay to in a tremendously heavy sea, from the 12 th of February until the 7th of April ere she dared to attempt crossing the bar. On the latter date, Douglas had the happiness of passing Cape Disappointment and of viewing from the vessel's deck the luxuriant growth of vegetation on the banks of the Columbia, which he regarded with anxiety as the scene of his future labors, but also with the highest satis- faction, for there was laid before him all that mortal could desire of beauty of landscape, and all that science might covet from any single portion of the habitable globe. Mr. Douglas's first excursions were made in the neighbourhood of Fort Vancouver, and he was there at once introduced to the modes of travelling that have to be adopted in a wild Indian country. Of a robust constitution and merry heart, he would with the greatest complacency wrap his blanket round him and stretch him- self out on the beach or under a bush as if he were lying down in a comfortable bed. In a few months he had collected a number of plants, many of them rare and new, and had besides dried the seeds he had 2;athered for sendinsr toEndand. SJcetch of the Life of Mr, David Douglas. 125 In the month of October, he had the pleasure of making his first shipment of plants and seeds for England by the same vessel in which he had sailed from London, and the Horticultural Society made the most of this collection. By the skill and care applied to the raising of the seeds, the gar- dens of England both public and private were quickly supplied with a share of the newly introduced plants, and the finest flowers of North-west America soon became generally distributed. Of the mode of life which had frequently to be adopted by our indefatigable collector, extracts from his own narrative will give the best explanation. " Early in the morning of the 19th July, I descended the river " in an Indian canoe for the purpose of prosecuting my researches " on the coast, a design which was in a great measure frustrated " by the tribe among whom I lived going to war with the nations *' residing to the northward, in that very direction which I in- " tended to follow. During my stay several persons were killed, and " some wounded in a quarrel. The principal chief in the village, " Cockqua, treated me with the utmost fidelity, and even built me " a small cabin in his own lodge, but the immense number of fleas " occasioned me to remove to within a few yards of the river : still " my friend was so much interested in my safety that he watched " himself a whole night, at the time that he expected the war party, ^' In the morning about three hundred men, in their war garments. " danced the war dance, and sang several death-songs, which " caused in me certainly, a most uncomfortable sensation, and the " following morning brought us seventeen canoes carrying nearly " four hundred men, when after several harangues, it was mutually " agreed to suspend hostilities for the present." '•' A sturgeon was caught by one of my companions, which " measured twelve feet nine inches, from the snout to the tip of " the tail, and seven feet round the thickest part, and its weight " exceeded five hundred pounds. Among the plants which I found " on this occasion, were, Lupinus Uttoralis, Carex 3Ienziesiiy *' Juncus Menziesil tind glohosus,Vaccinium ovatum, parvi/oUum " and ovaUfoUum. I also obtained seeds of the beautiful Sjnroea " ariafoUa, of Gicaltheria, Shallon, Rlhes sanguineus, Berheris, " and other valuable and interesting plants." " Before taking leave of my Indian friends, I purchased several " articles of wearing apparel, and things used in their domestic eco- *' nomy for which I paid in trinkets and tobacco. I arrived at Fort 1 26 Sketch of the Life of Mr, David Douglas, " Vancouver again on the 5tli of August,and employed myself until " the 18th in drying the specimens I had collected, and making " short journeys in quest of seeds and other plants, my labours being " materially retarded by the rainy weather. As there were no " houses yet built on this new station, I first occupied a tent " which was kindly offered me, and then removed to a lodge " of deerskin, which soon, however, became too small for me, in " consequence of the augmentation of my collections, and where " also I found some difficulty in drying my plants and seeds. A " hut constructed of the bark of the Thuja occidentalis was my ^' next habitation, and there I shall probably take up my winter '' quarters. I have only been in a house three nights since my ^' arrival in North-west America, and these were the first after my " debarkation. On my journeys I occupy a tent, wherever it is " practicable to carry one ; which, however, is not often, so that " a canoe turned upside down, is my occasional shelter ; but more " frequently I lie under the boughs of a pine tree, without any- " thing further." About the end of August, while on an excursion up the Multuomak or Willamette river, he became aware of the exis- tence of an enormous kind of pine, by finding very large pine seeds in the tobacco pouches of the Calapooeah Indians. When informed by these people that the tree was very large, and that its seeds were eaten as an article of food, he at once set about veri- fying this information, and gave the species the name of Lam- hertiana, so that this mighty tenant of the forest, second in size only to the gigantic Sequoia, (the Wellingtonia of Lindley,) now received its baptism or specific name, although, it was sometime afterwards, before Douglas saw it in all its magnificent propor- tions. In the month of September he visited the Cascades, heavy rapids of the Columbia, the first from the sea, and where the river breaks through the rocky barrier of the great volcanic range of Mounts Rainier and St. Helen's to the north, and their partners Hood and Jefferson to the south. After an unsuccess- ful attempt to scale the wooded summits on the north side, he returned, being short of food, and had two days repose ; when he oc- cupied his time with shooting seals as they descended the surging rapids, in quest of salmon. Starting then for an exploration of the other side, his wishes were gratified, and he gained the up- per wooded regions, where he was rewarded with many new plants, and discovered the Pinus nohilis and F, amaUUsj the former a Sketch of the Life of Mr. David Douglas. 127 spruce of much grandeur and straightness in growth, the latter the most elegant, perhaps, of all the Silver Firs. His exertions being thus crowned with success, the fatigued botanist turned his steps downwards towards Fort Vancouver, in order to look after his packages for England, of which we have already spoken. In the end of October, although much impeded in his move- ments, by a hurt which he had received in his knee, he was again afloat in a small canoe proceeding towards the mouth of the Co- lumbia. Leaving Cape Disappointment, he took the coast to the northward, sometimes making portages, and at others keeping with his Indian guide, in the tiny craft on rivulets skirting the shore. At Cape Foulweather, the canoe was abandoned and a march of sixteen miles made to gain Whitby Harbour, where the Chiheelis empties itself into the Pacific. Here we shall take up his own words. "On arriving there, when we found the village deserted, I can " hardly describe the state I was in. While my guide and the " Indians were collecting some drift-wood, I made a small booth of " pine branches, straw, and old mats My blanket having been " drenched all day, and the heavy rain affording no opportunity of '' drying it, I deemed it imprudent to lie down to sleep, and ac- " cordingly spent the night sitting over the fire. The following day '• found me so broken down with fatigue and starvation, and my " knee so much worse, that I could not stir out. We fared most " scantily on the roots of Sagittaria sagittifolia and Lupinus " UttoraUsjCQlhdi in the Chenook language, Somuchtau, till crawl- " ing out a few steps with my gun, I providentially saw some " wild birds, and killed five ducks at one shot. These were " soon cooked, though one of the Indians ate his share raw. To " save time in plucking the fowl, I singed off the feathers, and " with a basin of tea made a good supper on one of them. I had '' certainly been very hungry, yet strange to say, as soon as I saw " the birds fall, my appetite fled, and I could hardly persuade " myself that I had been in such want." Having procured assistance at a village on the opposite side of the bay, he turned up the Chiheelis river, but after being three days on this stream, he found the weather still continuing so rainy, that he discharged his guide, and hired another Indian with a horse to carry his luggage across to the Cowlidsk river. This distance, though only forty miles, occupied two days, all the low grounds being flooded with water j and the roads in the woods 128 SJcetch of the Life of Mr, David Douglas. marsliy with incessant rain. At the Cowlidsk, lie lighted upon a small boat, belonging to the Hudsons' Bay Company, which had been lent to an Indian chief. In this, by using his cloak and blanket for sail, he got back to Fort Vancouver at midnight on the 15th of November, completely worn out, and in nearly a famished state. The weather had done its worst, and his knee was in a still more painful condition from the fatigue and cold to which he had been exposed. He was now, therefore, compelled to lay himself up in winter quarters to recruit. The months of De- cember, January and February, were passed by him with his Van- couver friends, his time usefully occupied in collecting subjects of zoological interest, and working out in full the short notes he had taken on his various journeys. In March of 1826 the enterprising subject of our sketch being bent on a still more extensive tour than he had hitherto made, left his wintering station with the boats that were proceeding for the upper Columbia. At the Chutes, or first great falls of the river, six miles above the Dalles, the party, as was frequently the case there, had difficulties with the Indians in passing the portage, Douglas in his own lively manner describes the scene. " After taking a hurried and anxious breakfast on the rocks, " we proceeded several miles up the river, and in the afternoon " made the portage over the Great Falls, where Mr. McLeod was " apprized that the Indians were lying in wait with the intention ^' of attacking us, and pillaging the boats. This warning proved " too correct, no sooner had they received the customary present of " of tobacco, than they became desirous of compelling us to en- " camp for the night, that they might the better efiect their pur- " pose. The first symptom of hostile intentions which we ob- " served, was their cunning trick of sprinkling water on the gun- " barrels of our party, and when the boats were ordered to be put " into the water, they would not allow it to be done. As Mr " McLeod was laying his hand on the shoulders of one native to " push him back, another fellow immediately drew from his " quiver a bow and a handful of arrows, and presented it at Mr. " McLeod. My position at the time, at the outside of the crowd " enabling me to perceive this manoeuvre, and no time being to be " lost, I instantly slipped the cover of my gun, which was " fortunately loaded with buck-shot, and presenting it at him, I " invited him to discharge his arrow, when I would return it " with my own weapon. Just at this moment a chief of the Ky- Sketch of the Life of Mr, David Do7igIas, 129 ** ouse tribe, and three of his young men, who are the terror of ^' all the other tribes west of the mountains, and the staunch *' friends of the whites, (as they call us), stepped in among the " party, and settled the af&air without any further trouble. This *' very friendly Indian, who is one of the finest figures of a man " I have ever seen, six feet six inches high, then accompanied *' us several miles up the river to the spot where we intended " to encamp for the night, and was liberally renumerated by " Mr. McLeod for his courageous and timely interference, and *' friendship. I being King George's chief, or the " Grassman," *' bored a hole through the only shilling which I possessed, and " which had been in, my pocket ever since I left London, and *' observing that the septum of his nose was perforated, I suspended " the coin to it by a bit of brass wire, a ceremony which after- " wards proved a seal of lasting friendship between us." When he had reached Fort Colville, a short distance from the Kettle Falls, he was busily occupied for three weeks, when the lock of his gun having been broken, he determined on wending his way to the old, and then abandoned establishment at Spokan. Here resided old Jacquo Finlay, a remnant of the first Rocky Mountain Trappers, and once interpreter for the North-West Company among the Flat-head Indians. Jacquo was also the only craftsman who could work in good steel, within a distance of 800 miles. Starting with two youths to guide him, the traveller comes to the Barrier river, which has to be forded in passing from Col- ville to Spokan, and here we again take up his own description of the journey. " No natives being near to help us across in their canoes, my " two young companions and I had the alternative of making a " raft or swimming, and being all well accustomed to the water, " we chose the latter. Unsaddling the horses, we drove them in, " and they all crossed with safety and ease, except one poor animal " which getting entangled by its hind legs among some brushwood " at the bottom, struggled a long time till the impediment giving " way he finally relieved our anxiety by gaining the other side. *' I myself made two trips across, carrying my paper and gun the " first time and my blanket and clothes the second ; — the latter " articles I was obliged to hold above water in both my hands, " a difficult and tedious process, during which, as if to render my *' labour fruitless, it rained heavily. "When I landed, my whole " frame was so completely benumbed, that we were under the neces- Can. Nat. 4 Vol. V. No. 2. 130 Sketch of the Life of Mr, David Douglas. " sity of stopping to kindle a fire, and to indulge my gnides witli " a smoke, after which we proceeded. At night a severe pain be- " tween my shoulders, and general chillness kept me from sleep- " ing. I rose, boiled my kettle, and made some tea ; then dried my ^' blanket, and substituted for my damp shirt a spare one in *' which I had rolled my plants ; but feeling no better, and being " unfortunately without medicine, I started ou foot at a little be- '' fore four, and driving the horses before me, got into a profuse " perspiration which considerably relieved my sufferings. " Near this spot was an Indian burying ground, certainly the " most curious I had yet seen. All the property of the deceased *' was here deposited near their graves; their implements, garments, " and gambling articles. Even the favorite horse of the deceased " is not spared ; it is customary to shoot the animal with a bow *' and arrow, and suspend the skin, with the hoofs and skull, just *' above the remains of his master. On the trees which are round " the burying place, small bundles may be seen, tied up in the " same manner as the provisions which they carry when travelling. " I could not learn whether this was intended as food for the dead '' or propitiatory offerings to the divinities. Within the grave the " body is placed in a sitting posture, with the knees touching " the chin, and the arms folded across the chest. It is difficult to " obtain any information on these subjects, as nothing seems to " hurt the feelings of these people so much as alluding to their " departed friends." The gun having received thorough repair, and many new plants having been collected in this interesting locality, Mr. Douglas returned to Fort Colville, having passed in the same mode as before the Barrier river ; for this, however, he suf- fered : he was two days confined to bed by fever and bodily pains, caused no doubt by having walked so much in wet clothes. Dur- ing the rest of the month of May he made many excursions round Colville, and met with considerable success in collecting. He had since his arrival discovered a new Pinus ponderosa, on which he found the Arcenthohium xycedric, a parasitical plant exist- ing also in southern Europe. The beautiful genus Fentstemon was also enriched by three new species, P. scoulevj P. vetustus, and P. speciosus. On the 5th of June he left Colville and descended with the boats to "Wallander, an establishment just below Lewis and Clarke's Fork, then considered the key to the navigation of the upper Co- SJcetch of the Life of Mr, David Douglas, 131 lumbia. On the IGth when nearly ready for his journey to the Blue mountains we have a very amusing account of a nocturnal visit of rats (probably the Neotoma occidentalism) to his tent. " During the night I was annoyed by the visit of a herd of rats " which devoured every particle of seed I had collected, ate clean *' through a bundle of dried plants, and carried off my soap-brush, " and razor ! As one was taking away my inkstand, which I had " been using shortly before, and which lay close to my pillow, " I raised my gun, which with my faithful dog, is always placed " under my blanket by my side, with the muzzle to my feet, and " hastily gave him the contents. When I saw how large and " strong a creature this rat was, I ceased to wonder at the " exploits of the herd in depriving me of my property. The " body and tail together measured a foot and a half ; the back is " brown, the belly white ; while the enormous ears are each three " quarters of an inch long, with whiskers thi'ee inches in length, " and jet black. His journey to the Blue Mountains, occupying nine or ten days, did not turn out so productive as he had expected. He encoun- tered tremendous thunder-storms, his guide refused to descend the southern slopes, declaring that their horses would be stolen, and that they themselves would fall victims to the hatred of the Shosh- onies, or the Snake tribe, who are always on bad terms with the Columbia Indians. Before retracing his steps, however, he had the pleasure of plucking specimens of that magnificent plant, the LiLpinaster macrocephalus of Pursh, and of adding many new- species to the genera Liipinus^ Pedicidaris^ "^ Pentstemon and Eriogonum. The TrifoUum altisshnum and T. plumosum were also gathered, and last, though not least, the Pceonia Brownii now adorned his Herbarium. On the 10th of July Mr. Douglas left Wallawalla, proceeding down stream in a small canoe with Indians, Being unable to procure any salmon from the natives, and his stock of provisions entirely failing, he was for the first time reduced to the necessity of trying Tartar fare, and had supped and breakfasted on horse- steaks and Columbia water, when to his inexpressible joy he met, below the Chutes, the loaded boats that were so far on their way for the interior posts. The meeting is thus noticed. " Having halted at night below the Great Falls of the Columbia, " I saw smoke rising behind some rocks, and thinking it might be * Indians fishing, walked thither in quest of sabnon. Instead of 132 Silurian and Devonian Rocks " their savage countenances, I found, however, to my great delight, " that it was the camp of the brigade from the sea. I cannot des- " cribe the feeling which seizes me, when after travelling some " weeks together with Indians, I meet a person whom I have known '' before, or if even they are strangers, yet the countenance of a " Christian is at such times most delightful. In the present in- " stance I had the additional happiness of finding myself in the •' society of those who had ever treated me with cordiality, and '' who now seemed to vie with one another in acts of kindness to- " wards me. Observing my dejected and travel-worn plight, one " fetched me some water to wash with, another handed me a clean '' shirt, and a third busied himself in making ready something " more palatable than carrion for my supper ; while my old friends, " Messrs. McDonald and Work, handed me those best of cordials, '' my letters from England ! (Tb he continued.) ARTICLE XI. — On the Silurian and Devonian Eochs of Nova Scotia. By J. W. Dawson, LL.D., F.G.S. [Communicated to the Natural History Society of Montreal.] In the peninsula of Nova Scotia, the formations older than the carboniferous system, which is there so largely developed, are re- presented by disturbed and partially metamorphosed beds, occupy- ing a broad belt of country on the south-eastern or Atlantic coast, and certain irregular hilly tracts in the interior. These beds were described by me in a paper communicated to the Geo- loo-ical Society of London in 1849, and subsequently in my "Acadian Geology;" in which work will be found references to the labours of previous observers. These notices were confessedly very imperfect, owing to the difficulties of the formations them selves, the deficiency or bad state of preservation of the fossils, and the absence of sufficient suits of these for comparison. With the view of remedying these deficiencies, I have embraced such opportunities as have occurred to me since the publication of " Acadian Geology," to study these rocks in those parts of the country which appeared to promise the most satisfactory results. My collections of fossils have also been increased by contributions received from Dr. Webster of Kentville, who has long directed his attention to the New Canaan and Nictaux districts, which I have had the advantage of exploring under his guidance j from the Rev. of Nova Scotia, 133 D. Honeyman,* who has carefully collected the fossils of the Ari. saig section, and from Mr. C. F. Hart of Wolfville. Prof. Hall of Albany, has also kindly consented to apply his unrivalled knowledge of the palaeozoic fauna of America to the determi- nation of the fossils, and has enabled me to publish with this paper, his descriptions of the more important new species. With these aids, though aware that the complete solution of all the difl&culties of these deposits must await a systematic and detailed survey, I hope to fix with certainty the geological position of several important series of beds, and thus to afibrd some data for comparison with the formations of similar age in other countries.

In my paper of 1849, 1 attempted to arrange the whole of these infra-carboniferous rocks of Nova Scotia, in two great divisions : (1.) The slate and quartzite formation of the Atlantic coast. (2.) The slaty, calcareous, and ferruginous formation of the in- land hills. The second of these groups will be found in the sequel to include beds ranging from the Middle Silurian to the lower Devonian. The first is certainly older, and probably of Lower Silurian age. * See also a paper by Mr. Honeyman, in the Transactions of the N. S. Lit. & Sci. Society. 134- Silurian and Devonian Rocks I. — Lower Silurian. The Atlantic coast series, which I regard as probably of this age, has afforded little that is new since my former publication on the subject. It extends continously, with prevailing east and west strike and northerly dip, from Cape Canso to the middle of the peninsula at Halifax Harbour. Thence it continues with pre- vailing north-east and south-west strike to the western extremity of the province. Its most abundant rocks are coarse clay slate and quartzite in thick beds. In some districts the slates are re- presented by mica-schist and gneiss, and interrupted by consider- able masses and transverse bands of intrusive granite. It has afforded no fossils ; but it appears to be the continuation of the older slate series of Mr. Jukes* in Newfoundland, which has afforded trilobites of the genus Paradoxides.-f These fossils would indicate a position in the lower part of the Lower Silurian series, possibly on the horizon of the Potsdam sandstone or Lingu- la Flags. If so, the Lower Silurian limestones are either absent or buried by the unconformable superposition of the next series, or of the carboniferous beds which in some places immediately adjoin these older rocks. It is however proper to state that on a comparison of these rocks with the series of altered deposits from Eastern Canada, collected by the Canadian Survey, and elaborately examined by Mr. Sterry Hunt, they appear more nearly to resemble those of the Hudson River group than any other of the series. It seems also, that chiastolite and staurotide, which occur abundantly in some parts of the Nova Scotia coast series, as for example, at Cape Canseau and in Shelburne, are characteristic in Canada and New England of altered Upper Silurian and Devonian rocks. It is possible that this last fact may be accounted for by the local oc- curence of some beds newer than the others ; and the characters of the Silurian and Devonian series, as seen elsewhere in Nova Scotia, seem at least to exclude the mass of these coast rocks from any formation newer than the Middle Silurian. II. — Middle akd Upper Silurian. The inland group of metamorphic rocks is more variable in its character, presenting many varieties of shales and slates some- *Survey of Newfoundland. t Salter, Proceedings Geological Society of London, 1859. of Nova Scotia, 135 times talcose and chloritic, often coarse and arenaceous, and asso- ciated with beds of sandstone and quartzite, and with calcareous layers. In some districts there are also extensive beds which have the appearaneo of interstratified igneous products both of horn- blendie and felspathic composition. The associated igneous rocks are granite (which appears to be continuous with that of the coast series and intrusive), syenite, diorite, porphyry and compact fel- spars. The more highly altered portions are penetrated by num- erous veins of peroxide and carbonate of iron, with copper and iron pyrites. These beds, as well as the overlying Devonian series, have been thrown into folds, varying in direction from east and west to north-east and south-west, and have been at the same time much altered and disturbed by plutonic rocks. They afterwards suffered extensive denudation, forming both anticlinal and syn- clinal valleys, in which were deposited beds of the carboniferous system, and of the New Red Sandstone of Nova Scotia, a deposit still of uncertain age.* This denudation has appar- ently been so complete as to remove from view nearly all the softer and least altered beds, the remains of which appear principally at the margins of the valleys now filled by the carboniferous series. Even in these exceptional spots they have in some instances been farther obscured by trappean eruptions of carboniferous or later date. The following are the principal localities in which I have been able to obtain determinable fossils. The geographical posi- tion of these points is noticed in the accompanying map. (Fig. 1, p. 132.) Arisaig. Near this place, at the extreme northern limit of the Silurian system on the eastern coast of Nova Scotia, is one of the most in- structive sections of these rocks in the province. At the eastern end of the section, where they are unconformably overlaid by lower carboniferous conglomerate and interstratified trap,f the Silurian rocks consist of gray and reddish sandy shales and coarse limestone bands dipping south at an angle of 44°. The direction of the coast is nearly east and west, and in proceeding to the east- ward, the dip of the beds turns to south 30^ west, dipping 45°, * See Journal Geol. Society, Vol. 4, and Acadian Geology. fSee papers by the author in Proceedings Geological Society, 1843-4. 136 Silurian and Devonian Roch so that the series, though with some faults and flexures, is on the whole descending, and exhibits in succession to the rocks just mentioned, gray and dark shales, with bands and lenticular patches of coarse limestone, some of which appear to consist principally of brachiopodous shells in situ, while others present a confused mass of drifted fossils. Below these the beds become more argil- laceous, and in places have assumed a slaty structure, and occasion- ally a red colour. The thickness of the whole series to this point was estimated at 500 feet. The dip then returns to the south, and the beds run nearly in the strike of the shore for some distance, when they become discoloured and ochraceous, and then red and hardened ; and finally, at Arisaig pier, are changed into a coarse reddish banded jasper, where they come into contact with a great dyke of augitic trap of carboniferous date. Beyond this place they are much disturbed, and so far as I could ascertain, destitute of fossils. The alteration of the beds extends to a distance of 300 yards from the trap, and beyond this in some places slaty cleav- age and reddish colours have been produced ; the latter change appearing to be connected with vertical fissures traversing the beds. In the lower or shaly portion of the Arisaig series, the charao- terstic fossils are GraptoUthus not distinguishable from G. clinto- nensis, Leptoccelia (Atri/pa) intermedia, (Hall,) a new species closely allied to L. hemispherica of the Clinton group of New York, Atrypa emacerata, Orthis testudinaria, Strophomena profunda, S. rugosa, Rhynconella equiradiata, Avicula ema- cerata, TentacuUtes, allied to or identical with T. distans, Helo- j^ora allied to H. fragills. There are also abundant joints and stems of crinoids, and a Palceaster, the only one as yet found in Nova Scotia, which was presented to me by Mr. Honeyman, and has been described by Mr. Billings in the Canadian Naturalist un- der the name of P. parviusculus. These and other fossils associat- ed with them, in the opinion of Prof. Hall, fix the Geological position of these rocks as that of the Clinton group, the upper Llandovery of Murchison, at the base of the upper Silurian or top of the middle Silurian. In the upper and more calcareous part of the series, fossils are very abundant, and include species of Calymene, Dalmanites, Homalonotus, Orthoceras, Murchisonia, CUdopliorus, TelUnomya, and several brachiopods, among which are Discina tenuilamellata^ Lingula ohlongaj Rhynconella quadricosta, R. Saffordij (Hall,) of Nova Scotia* 137 allied to R. Wilsoni, R. neglecta, Atrypa reticularis,^ all found in the upper part of the Middle Silurian or in the Upper Silurian elsewhere in America. Most of the other forms are new species, descriptions of which will be found in Prof. Hall's paper appended to these notes. The general assemblage is on the whole like that of the Clinton, but is of such a character as to warrant the belief that we may have in these beds a series somewhat higher in position, and probably of Upper Silurian age. The new species Chonetes Nova-Scotlca is very characteristic of the upper member. On the whole we must regard the Arisaig series as representing the upper part of the Middle Silurian, probably with a part of the Upper Silurian, a position much lower than that assigned to it in my Acadian Geology, which was, however, at the time, based on the opinions of the best palaeontologists who had examined specimens from these rocks. Unfortunately the Arisaig series stands alone, wedged between carboniferous and plutonic rocks, so that no opportunity occurs on the coast of verifying these conclu- sions derived from fossils, by the evidence of stratigraphical con- nection with newer or older Silurian deposits, and I have been un- able to devote sufficient time to this object to attempt to trace the beds in their succession or continuation inland. V East River of Pictotj. The next example of fossiliferous Silurian rocks known to me is on the east branch of the East River of Pictou, and its vicinity, where these deposits rise from beneath the lower carboniferous series, forming the high ground on the eastern side of the river. The beds are here much altered and penetrated by igneous dykes, and are vertical, with very high southerly dips and N. E. and S. W. strike. They consist of coarse slates and calcareous bands resembling those of the upper Arisaig series in mineral character, and holding many of the same species, especially Chonetes Nova- Scotica ; but we have here in addition a great bed of fossiliferous peroxide of iron, in some parts forty feet in thickness, and with ooli- tic structure ; but passing into a ferruginous sandstone, and associ- ated with slate and quartz rock. The age of these rocks relatively to the Arisaig series, it is not easy to determine. The stratigraphi- cal evidence, though obscure, would place them in a higher position. The fossils are in a bad state of preservation ; but in so far as * Also Strophomena corru§ata. 138 Silurian and Devonian Rocks they give any information, it coincides with the apparent relation of the beds. Similar ferruginous beds occur in the Clinton series, (the Surgent of Rogers) in New York and Canada ; and as we shall find in the sequel, in a much higher position in the western part of Nova Scotia. On the whole I regard the beds seen at the East River of Pictou as belonging to the same line of outcrop with the Arisaig series, but as containing in addition to the upper member of that series, beds higher in the Silurian system, or perhaps Lower Devonian. CoBEQUED Mountains. At the eastern end of this chain, in Earlton and New Annan, though the rocks are generally in a highly metamorphosed con- dition, fossils are found in a few places ; and in so far as I have been able to determine from very small suites of specimens, are those of the upper Arisaig series. From the apparent continuity of strike along this long salient line of outcrop, it seems probable that these fossils indicate the true age of the greater part of the sedimentary rocks of the Cobequid hills ; a conclusion confirmed by their similarity in mineral character to the altered equivalents of the Arisaig and East River series as seen elsewhere. The arrangement of the beds and their mineral contents in the central part of the chain, will be found noticed in my paper of 1849, already referred to. They are not known to contain beds of iron ore ; but have enormous vein-like deposits of spathic and specular iron associated with the carbonates of lime and magnesia, and run- ning with the strike of the beds. New Canaan. Between the East River of Pictou, and New Canaan in King's county, 100 miles distant, I know no Silurian beds with fossils ; and in the central part of the province these rocks disappear under the carboniferous deposits. In the hills of Horton and New Canaan they reappear, and constitute the northern margin of a broad belt of metamorphic and plutonic country, occupying here nearly the whole breadth of the peninsula. The oldest fossiliferous beds seen are the fine fawn-coloured and gray clay slates of Beech Hill, in which Dr. Webster, many years since, found a beautiful Dictyonema^ the only fossil they have hitherto afforded. It is a new species, closely allied to D. retiformis and D. gracilis of Hall, and will be described by that palaeontologist under the name of D, Websteri, in honour of its discoverer. In of Nova Scotia, 139 the mean time I may merely state that it is most readily charac- terised by the form of the celkiles, -which are very distinctly marked in the manner of Grajptolithus, A portion of a frond is represented in Fig. 2. Fig. 2. — Part of frond of Dictyonema Websterij Hall, a, portion magnified. The Dictyonema slates of Beech Hill are of great thickness, but have in their upper part some hard and coarse beds. They are succeeded to the south by a great series of dark coloured coarse slates, often micaceous, and in some places constituting a slate conglomerate, containing small fragments of older slates, and occasionally pebbles of a gray vesicular rock, apparently a trachyte. In some parts of this series there are bands of a coarse laminated magnesian and ferruginous limestone, containing fossils which, though much distorted, are in parts still distinguishable. They consist of joints of crinoids, casts of brachiopodous shells, trilobites and corals. Among the latter are two species of As- trocerium, not distinguishable for A. pyriforme and venustum of the Niagara group, and a Heliolites allied to H. elegans, if not a variety of this species. On the evidence of these fossils and the more obscure remains associated with them. Prof. Ilall regards these beds as equivalents of the Niagara formation of the New York geologists, the Wenlock of Murchison. Their general strike is N. E. and S. W. ; and to the southward, or in the pro- bable direction of the dip, they are succeeded, about six miles from Beech Hill, by granite. They have in general a slaty structure coinciding with the strike but not with the dip of the beds, and this condition is very prevalent throughout this inland metamor- phic district, where also the principal mineral veins usually run with the strike. The beds just described run with S. W. strike for a considerable distance, and are succeeded in ascending order by those next to be described. ni. — Devonian. It is probable that Devonian rocks, in a metamorphosed state 140 Silurian and Devonian Rocks are extensively distributed througliout the districts now under consideration ; but the only localities in which they have been clearly recognised, are along a line of outcrop on the northern margin of the hilly region westward of New Canaan. The first and most important of these exposures is at NiCTAUX. At this place, 20 miles westward of New Canaan, the first old rocks that are seen to emerge from beneath the New Red Sand stone of the low country, are fine-grained slates, which I believe to be a continuation of the Dictyonema slates of Beech Hill. Their strike is N. 30 to 60 E., and their dip to the S. E. at an anMe of 72^. Interstratified with these are hard and coarse beds, some of them having a trappean aspect. In following these rocks to the S. E , or in ascending order, they assume the aspect of the New Canaan beds ; but I could find no fossils except in loose pieces of coarse limestone, and these have the aspect rather of the Arisaig series than of that of New Canaan. In these, and in some specimens recently obtained by Mr. Hart, I observe Orthoceras elegantulmn, Bucania trilohita, Cornulites Jiexuosus, Spirifer rugcecosta f and apparently CJionetes NbvaSco- tica^ with a large Orthoceras^ and several other shells not as yet seen elsewhere. These fossils appear to indicate that there is in this region a continuance of some of the upper Arisaig species nearly to the base of the Devonian rocks next to be noticed. After a space of nearly a mile, which may represent a great thickness of unseen beds, we reach a band of highly fossiliferous peroxide of iron, with dark coloured coarse slates, dipping S. 30° E. at a very high angle. The iron ore is from 3 to 4j feet in thick- ness and resembles that of the East River of Pictou, except in containing less silicious matter. The fossils of this ironstone and the accompanying beds, as far as they can be identified, are Spirifer arenosus^ St7'ophodonta magmjim^ Atrypa unguiformis, * There is in the iron ore and associated beds another and smaller Spirifer as yet not identified with any described species, but eminently characteristic of the Nictaux deposits. It is usually seen only in the state of casts, and often strangely distorted by the slaty structure of the beds. The specimens least distorted may be described as follows : General form, semi-circular tending to semi-oval, convexity moderate ; hinge line about equal to width of shell ; a rounded mesial sinus and elevation with about ten sub-angular plications on each side ; a few sharp growth ridges at the margin of the larger valves. Average dia- meter about one inch ; mesial sinus equal in width to about three plica- tions. I shall call this species, in the meantime, S, Nictavensis. of Nova Scotia. 141 Stro]jTiomena depressa^ and species of Avicula, Belleroplion^ Favo- sites, Zaphrentis, &c. These Prof. Hall compares with the fauna of the Oriskany sandstone ; and they seem to give indubita- ble testimony that theNictaux iron ore is of Lower Devonian age. To the southward of the ore the country exhibits a succession of ridges of slate holding similar fossils, and probably represent- ing a thick series of Devonian beds, though it is quite possible that some of them may be repeated by faults or folds. Farther to the south these slates are associated with bands of crystalline greenstone and quartz rock, and are then interrupted by a great mass of white granite, which extends far into the interior and separates these beds from the similar, but non-fossiliferous rocks on the inner side of the metamorphic band of the Atlantic coast. The Devonian beds appear to dip into the granite, which is in- trusive and alters the slates near the junction into gneissoid rock holding garnets. The granite sends veins into the slates, and near the junction contains numerous angular fragments of altered slate. Westward of the Nictaux River, the granite abruptly crosses the line of strike of the slates, and extends quite to their northern border, cutting them off in the manner of a huge dyke, from their continuation about ten miles further westward. The beds of slate in running against this great dyke of granite, change in strike from south-west to west, near the junction, and become slightly contorted and altered into gneiss, and filled with granite veins ; but in some places they retain traces of their fossils to within 200 yards of the granite. The intrusion of this great mass of granite without material disturbance of the strike of the slates, conveys the impression that it has melted quietly through the stratified deposits, or that these have been locally crystallised into granite in situ. Moose River. At this place the iron ore and its associated beds recur on the western side of the granite before mentioned, but in a state of greater metamorphism than at Nictaux. The iron is here in the state of magnetic ore, but still holds fossil shells of the same species with those of Nictaux. Bear River. On this stream, near the bridge by which the main road crosses it, beds equivalent to those of Nictaux occur with a profusion 142 Silurian and Devonian Rocks of fossils. The iron ore is not seen, but tliere are highly fossil- iferous slates and coarse arenaceous limestone, and a bed of gray sandstone with numerous indistinct impressions apparently of plants. In addition to several of the fossils found at Nictaux, these beds afford Tentaculites^ an Atrypa, apparently identical with an undescribed species very characteristic of the Devonian sandstones of Gaspe, and a coral which Mr. Billings identifies with the Pleurodictyum p'ohlematicum^ Goldfuss, a form which occurs in the Lower Devonian in England, and on the continent of Europe. Westward of Bear Eiver, rocks resembling in mineral charac- ter those previously described, extend with similar strike, but in an altered condition, and in so far as T have been able to ascertain, destitute of fossils, quite to the western extremity of the peninsula, where they turn more to the southward, and are as I suppose, repeated by a sharp synclinal fold, after which they are succeeded by the Atlantic coast series, consisting of quartzite and clay slate, with chlorite and hornblende slates at Yarmouth and its vicinity, and further to the S. E. of mica slate and gneiss. General Remarks. The above facts show that we can recognise among the partially metamorphosed sub-carboniferous rocks of Nova Scotia, forma- tions ranging from the Middle Silurian to the Lower Devonian inclusive ; but of a more argillaceous and less calcareous charac- ter than the series occupying this position in the mainland of America. The principal masses of plutonic rock associated with these beds, and especially the granite, are of newer Devonian date ; but there is evidence of igneous eruptions as far back as the beginning of the Upper Silurian, and of the continuance or recurrence of such action as late as the carboniferous period. In and near the non-calcareous Lower Silurian series, granite prevails, almost to the entire exclusion of other plutonic rocks. At a greater distance from these, the plutonic rocks penetrating the Upper Silurian and Devonian series, though apparently of nearly the same age with the granite, are principally syenite and green- stone. With respect to the general arrangement of the formations, though I cannot venture to speak with confidence on this point, with reference to a district so much disturbed, and which 1 have been able only very imperfectly to explore, I may suggest, as at of Nova Scotia. 143 presenr the most probable arrangement, that represented in the little section attached to the map. The coast series would thus belong to an anticlinal, bringing up Lower Silurian rocks. On these, in proceeding to the north-west, rest middle and upper Silurian and perhaps Devonian beds in a metamorphosed condi- tion, which along the northern margin of the metamorphic dis- trict rise again with an opposite dip, at Arisaig, East River, New Canaan, &c., forming a trough, the middle of which, in the east, is divided by a secondary anticlinal and filled with carboniferous rocks, but in the west is occupied with a great mass of granite into which the beds appear to have sunk in the direction of their dip. Beyond the northwestern edge of this trough, the Silurian beds probably again dip to the northward, but are hidden by carboniferous deposits, and reappear in another anticlinal with east and west strike in the Cobequid Mountains. Rocks similar in character and relations to those above described are extensively distributed in the Island of Cape Breton and also in New Brunswick, but I have no detailed knowledge of their distribution. The formations described in this paper, represent in age, and resemble in their state of alteration, many portions of the metamorphosed Silurian and Devonian rocks of New England and Eastern Canada. In the latter, the relations of the intrusive granite and the middle and upper Silurian rocks as described by Sir William Logan, and as I have observed them in a few locali- ties, strikingly resemble the phenomena observed in Nova Scotia. I have no doubt that a detailed survey of these rocks in Nova Scotia and Cape Breton, would develop many curious and intri- cate disturbances, and might also ascertain the presence of mem- bers of the Silurian series, now supposed to be absent, but which may be only obscured by denudation. In the mean time local observers can do much to increase our knowledge of these rocks by carefully collecting the few fossils that remain unobliterated in the semi-metamorphic beds, and the above remarks may serve to guide such explorations, and to enable geologists to speak with more confidence than heretofore of the older palaeozoic rocks of an important region of eastern America. 144 Silurian Fossils of Nova Scotia, ARTICLE XII. — Descriptions of New Species of Fossils from the Silurian Rocks of Nova Scotia. By James Hall. 1. Crania acadiensis. N. sp. Fig. 1. Circular or broadly sub-oval, moderately convex, the greatest convexity near the apex ; apex obtuse. Several casts show a central elevated area, with strong muscu- lar impressions ; the more elevated portion being surrounded by a flattened border, which is radiatingly striate. These specimens are casts which appear to be of the ventral valve; and the form of the nmscular impressions is so character- istic of the genus that I can have little hesitation in thus referring them. 2. DisciNA tenuilamellata. Var. suhplana. Shell broadly elliptical, or suborbicular, externally depressed, apex subcentral ; surface marked by thin sharply elevated lamellae. This closely resembles the Niagara species of New York, but may be distinct. Should further examination prove it a distinct species, the name D. suhplana may be adopted. Fig. 2. Fig. 3. Fig. 1. Fig. 5. Fig. 4. 3. Chonetes Nova-Scotica. N. sp. Fig. 2. Shell semielliptical, width varying from once and a half to nearly twice the length. The ventral valve variably convex, and often showing a flattened or slightly concave space down the middle of the shell ; cardinal margin ornamented by four or five minute spines on each side of the beak ; cardino-lateral margins often a little wrinkled ; surface finely striated, strise flexuous, dichotomising and increasing by interstitial addition, so that there are more than one hundred on the margin of the shell ; strise increasing in size below the umbo ; concentric strise fine, close, rounded and slightly undulating. Dorsal valve moderately concave ; strise much stronger below the middle of the shell and sometimes bifurcating toward the margin. Silurian Fossils of Nova Scotia, 145 This species resembles in form the Chonetes cornuta of the Clinton group of !N'ew York, but is a much larger and more ven- tricose shell ; the striae are proportionally less numerous and more closely arranged, the interstices being less than the striae, while in the C. cornuta the interstices are wider than the striae, and the latter increase only by interstitial additions below the middle of the sheU. A stronijer and more elevated stria often marks the median line from beak to base of the ventral valve. 4. Chonetes tenuistriata. N. sp. Fig. 3. Shell semi-oval, twice as wide as long ; ventral valve moderately convex, hinge line equalling the width of the shell ; surface marked by fine, even, closely arranged striae, which apparently increase only by interstitial additions, and are not flexuous. The number of striae on the margin of the shell is nearly one hundred. This species is more finely striated than the preceding, the striae not flexuous, more even, and in shells of equal size much more numerous. This species is somewhat larger and more closely striated than the C. cornuta of the Clinton group of New York. 5. Spirifer rug^gosta. InT. sp. Shell somewhat semi-elliptical ; dorsal valve very convex, with the mesial fold depressed along the centre ; ventral valve with a wide deep mesial sinus ; plications six or seven on each side of the mesial fold and sinus, strong, and much elevated, subangular, crossed by numerous strongly elevated, lamellose, imbricating concentric striae. The specimens examined are almost all imperfect casts, some of which preserve the impression of the strong concentric striae, and in one or two specimens an impression of the shell reveals the streno^th of the surface markings. In many respects this species resembles the S. perlamellosa of the lower Helderberg group in New York, but the mesial elevation of this species is flattened or depressed, a character never observed in New York specimens. 6. Spirifer subsulcatus. N. sp. Shell semi-elliptical, hinge line equalling or greater than the length of the shell below ; plications five or six on each side of the Can. Nat. 5 Vol. Y. No. 2. 146 Silurian Fossils of Nova Scotia, mesial fold ; mesial fold somewhat flattened or very slightly roimd- ed on the summit ; plications rounded ; surface concentrically lamellose. The specimens are all casts, or impressions of the shells. They bear some resemblance to S. sulcatus of the Niagara group, and are intermediate between that species and the S. cyclop- iera of the Lower Helderberg group. 1, Tremastospira Acadia. N. sp. Fig. 4. i ■ Shell wider than long ; beak of the ventral valve produced and incurved ; mesial depression marked by a small fold on each side^ which originates about one-third of the length below the beak and continues to the margin ; sinus bounded on each side by a more strongly elevated plication, beyond which are six other plications on each side. Surface marked by fine concentric stri?e. This shell is referred to the genus Trematospira from external characters alone, which are unlike Bhynchonella proper, and the shell is not a Spirifer. 8. Rhynohospira sinuata. N. sp. Shell ovoid, ventricose beak of the ventral valve incurved ; a mesial sinus beginning a little below the beak ; surface marked by about eight or nine simple scarcely subangular plications on each side the mesial sinus. Surface marked by concentric lines of growth. This species differs from the R. formosa of the Lower Helder- berg rocks of New York in the plications being more slender, in the more defined sinus of the ventral valve, and the continuation of the two small folds in the sinus nearly to the beak. 9. Rhynchoneila Saffordi. Shell varying in form from ovoid to globose. Full grown spe- cimens usually wider than long, and sometimes becoming ex- tremely ventricose, so that the diameter across the two valves much exceeds the length. Ventral valve depressed convex, with the beak minute, closely incurved ; dorsal valve very ventricosey most prominent toward the front. Cardinal slope a little de- pressed, sides rounded, and the front in direct line flattened but not depressed. Surface finely plicated, plications little elevated^ Silurian Fossils of Nova Scotia, 147 rounded or scarcely subangular, about five or six depressed in the flattened sinus of tlie ventral valve and a corresponding number raised on the flattened mesial elevation, which rises abruptly though usually but slightly above the lateral portions of the shell. From ten to fourteen plications mark the surface on each side of the mesial fold and sinus. Plications in front marked by a sharp groove along the centre, and those of each valve deeply interlocking. This species resembles the i?. nucleolata of the Lower Helder- berg rocks of New York, and in some specimens it approaches to H.ventricosa, but is always much more finely plicated than either. It closely resembles the E. Wilsoni of Europe in its general form, but the plications are more rounded and somewhat coarser, and while in that species the sinus causes no depression in the ventral valve below the general surface of the shell, in ours there is an abrupt depression as well as a slightly abrupt elevation on the dorsal valve, while there is no similar feature in the R. Wilsoni* The Nova Scotia specimens are in all respects identical with those from Tennessee. The geological position of the specimen from Tennessee is in rocks of the age of the Lower Helderberg group, associated with Pentamerits galeaius, P. Verneuili, Spirifer macropleura^ Spiri- fer perlamellosay Spirifer cyclopteray and others. 10. Leptocelia intermedia. Fig. 5, N. sp. Shell concavo-convex ; outline semi-elliptical, cardinal extremi- ties rounded, and the hinge-line a little shorter than the greatest width of the shell ; ventral valve moderately convex, carinate in the middle by a strong plication, with six or seven smaller ones on each side, the lateral ones slightly curved towards the outer extremity. Dorsal valve concave, with a broad shallow mesial sinus, the margins on either side being bent a little upward, giving a sinuous outline to the margin of the shell ; surface marked by fine concentric striae. This species resembles the L. hemispherica of the Clinton group in New York, in general form, but the hingeyine is shorter and the extremities rounded ; the mesial elevation consists of a single strong plication, while in L. hemispherica the surface is regularly plicated, with the central one sometimes a little stronger than the others. ♦Sowerby, M. C, vol. ii., page 38, says : The " sinus at the front, al- though deep, does not alter the evenness of the surface." 148 Silurian Fossils of Nova Scotia. 11. MODIOLOPSIS ? RHOMBOIDEA. N. Sp. Fig. 6. Shell sub-rhomboid, rounded in front, wider and obliquely trun- cate behind, hinge-line slightly ascending from the anterior end ; beaks subterminal, posterior umbonial slope obtusely subangular below, anterior to which the shell is flattened ; basal margin nearly straight, the shell gradually widening behind and the posterior basal extremity abruptly rounded. Surface evenly striated con- centrically. Anterior muscular impression very strong, posterior muscular impression less strongly defined, but still very conspicuous and sub-duplicate ; palleal line simple, nearly parallel to the basal margin, strongly and almost equally defined in all parts of its length between the two muscular imprints. This shell bears some resemblance to M . primiffenius, but is less ventricose in tlie middle, and the sub-angular umbonial slope ia not so well defined in that species. 12. MODIOLOPSIS SUB-NASUTUS. N. Sp. Shell elongate sub-spatulate, tlie length being more than twice "the greatest width hinge-line ; sliglitly ascending posteriorly ; beaks sub-anterior, the anterior end very narrow, gibbous on the umbones, with a sub-angular ridge on the umbonial slope which extends to the postero-basal angle ; basal margin nearly straight, the posterior end somewhat flattened and obliquely sub-truncate at the extremity ; surface marked by concentric lines of growth. This shell bears a close general resemblance to M. nasutus of the Trenton limestone, but a careful comparison shows it to be wider and more abrupt at its posterior termination, while the direction of the striae of growth is very distinctive, these marks being regularly curving toward the posterior end in M. nasutus, while in this species they are abruptly bent at the postero-basal angle, and again on the cardinal side, corresponding with the truncate posterior extremity of the shell. 13. Clidophorus cuneatus. N. sp. Shell ovoid, gibbous in the middle and on the umbones, gra- dually declining behind ; beaks anterior, sub-terminal ; anterior •end broadly rounded, the posterior end narrower and sub-acute, posterior umbonial slope marked by an obtuse rounded ridge, (which extends to the posterior extremity, and below this an unde- Silurian Fossils of Nova Scotia. 149 fined sinus which, expanding, extends to the postcro-basal extre- mity, while a less defined ridge bounds this sinuosity on its anterior side ; surface marked by fine irregular concentric striae. In the casts of this shell there is a strong linear straight clavi- cle, extending from a point just anterior to the beak two-thirds across the valve. Fig. 6. Fig. 1. Fig. 8. 14. Clidophorus concentricus. N. sp. Fig. 7. Shell sub-equilateral, very broadly oval-ovate, the anterior end the broader ; height nearly four-fifths the greatest length ; anterior side a little shorter and more broadly rounded at the extremity ; a slight depressed sinus on the posterior umbonial slope, which is more anterior than in the preceding species. Surface marked by even band-like concentric striae ; shell thin ; a linear curving cla- vicle extends from the cardinal line just anterior to the beak more than half way to the base. The prominent points of distinction between this and the pre- ceding shell are the nearly central beaks, the band-like striae, and the curving clavicle with the broad and nearly equal extremities of the valve. 15. Clidophorus erectus. N". sp. Fig. 8. Shell somewhat rhomboid-ovate, the height and length about equal ; umbones prominent, beaks nearer the anterior end, some- what curved and elevated ; posterior cardinal line curving, with a scarcely defined ridge along the umbonial slope ; basal margin strongly rounded, sinuate on the postero-basal margin and regu- larly rounded, with a scarcely defined ridge extending down the slope just anterior to the clavicle. Surface finely striated concen- trically, a slightly curving clavicle extending from the cardinal line nearly two-thirds the distance to the anterior basal margin. This species differs from the preceding in the equal length and breadth and consequent greater proportional height, in the sinu- osity of the postero-basal margin, and more abruptly-rounded basal outline, and the curving forward of the beaks. 150 Silurian Fossils of Nova Scotia* 16. Clidophorus elongatus. N. sp. Fig. 9. Shell sub-elliptical, length about twice the height, beaks much nearer to the anterior end, which is narrowly rounded ; umbones rounded, prominent ; a defined gradually widening depression extends from the umbo to the posterior basal margin, causing a straightening or slight sinuosity in the edge of the shell ; a defined ridge along the posterior slope between the sinus and the cardinal margin. Surface very finely striated. A slender clavicle extends from the anterior cardinal margin a little more than half-way to the base, and curving slightly forward. This species differs externally from all the others in the greater proportional length and in the rounded umbones. The C. cuneatus of the same size is a stronger and proportionally higher shell, having a less defined sinus on the posterior slope, and a much stronger clavicle. Fig. 9. 1*7. Clidophorus semiradiatus. N. sp. Shell somewhat oval-ovate, length about one third greater than the height. Surface marked by fine concentric band-like strife, and the posterior slope by flattened dichotomized radiating striae, the two sets of striae gradually dying out at their junction. A faint line anterior to the beak marks the place of the clavicle. 18. Clidophorus nuculiformis. N. sp. Shell nearly equilateral, subventricose, height and length as seven to nine. Anterior end rounded, basal margin regularly curved ; posterior end sub-acute, a slight flattening or depression along the posterior umbonial slope, and between this and the car- dinal line a narrow ridge. On the anterior slope there is a de- pressed line almost parallel to the cardinal line, marking apparently the course of the clavicle. Surface marked by fine concentric striae. This species resembles in form the 0. concentricus in its equila- teral form, but the fine unequal concentric striae and the difference in direction of the clavicle are sufficient to distinguish it. Silurian Fossils of Nova Scotia. 151 19. Clidophorus subovatus. N. sp. Shell, broadly oval or ovate, moderately and evenly convex ; beaks near the anterior end ; umbones moderately elevated ; a scarcely defined depression extending from the umbo towards the postero-basal extremity ; anterior extremity rounded, posterior extremity unknown (? regularly rounded) ; clavicle extending half way from the anterior cardinal margin to the base of the shell. Surface marked by fine unequal sub-lamellose striae. This shell is larger and more regularly convex than any of the others here described, and more inequilateral than any except the C, cuneaius. 20. NucuLiTEs [Orthonota] carinata. N. sp. Fig. 10. Shell extremely elongate, nearly three times as long as wide ; sides sub-parallel ; hinge line straight, beaks appressed, sub-an- terior, the anterior extremity rounded ; posterior extremity obli- quely truncate, longer on the hinge line than on the basal margin. Surface marked by a sharp carina which extends from the umbo obliquely to the postero-basal angle, the space anterior to this car- ina marked by distinct elevated lamellose striae, and intermediate finer ones. The space between this and the cardinal line smooth and slightly depressed. Cardinal line anterior to the beak show- ing six or seven crenulations. A strong clavicle extends from the anterior cardinal line with a gentle curve nearly to the base of the shell. Fig. 10. Fig. II. Fig. 12. This shell presents characters not before observed combined in one species. It has the general form of Ortkonta, while the crenulated cardinal line and the anterior clavicle are characters of Nuculites. The shell is readily distinguished from species of either genus heretofore described. The Orthonotae, yet known, have the surface marking much less sharply defined. 21. Tellinomya Attentjata. N. sp. Fig. 11. Shell elongate, narrow, more than twice as long as high, an- terior end short and rounded, beak elevated, situated a little in 152 Silurian Fossils of Nova Scotia, advance of the anterior third, posterior end narrow and abruptly rounded; basal margin slightly curved, and impressed posterior to the centre ; posterior cardinal line straight but gradually de- clining ; contour evenly convex. Surface concentrically striated, shell thick. This shell resembles the T. machceriformisj bnt the anterior end is proportionally longer and more regularly round, the pos- terior narrower and more attenuated, and the convexity of the shell much greater. It is much smaller and proportionally more elongated than the T. nasuta of the Trenton Limestone. 22. Tellinomya angustata. N. sp. Shell elongate, narrow elliptical, more than twice as long a& wide, beaks fully one third from the anterior end. The anterior and posterior ends similar and equally rounded ; basal margin regularly curved without indentation or sinuosity. Surface even- ly convex and very finely concentrically striated. 23. Leptodomus, (Sanguinolites,) aratus. N. sp. Shell rhomboid-ovate, ventricose, beaks at the anterior third of the valve, incurved and pointed forward, umbones gibbous, a slight depression from the umbo directly to the base of the shell leaving a slight impression in the central margin ; posterior slope sub-angular, the angle not defined ; anterior slope with a defined angular ridge which borders a large cordiform liinette ; anterior sharply rounded ; basal margin nearly parallel with the hinge line, curving upwards at the posterior extremity, and somewhat obliquely truncated from the cardinal line. Cardinal line straight posteriorly, with a wide and deep ligamental area. Surface marked by strong unequal ridges and furrows parallel to the basal margin, which become obsolescent on the posterior cardinal slope. It is scarcely possible to refer any fossil with satisfaction to the genera Sanguinolites or Leptodomus of McCoy, since the group- ing of species under these names appears to us to comprise a heterogeneous assemblage in either case. Our shell corresponds in its external features with Leptodomus costellatus of McCoy, so far as the general form, surface markings, ligamental area, etc. and is doubtless generically identical with that shell. Silurian Fossils of Nova Scotia, 153 24. MfiaAMBONlA (?) CANCELLATA. N. Sp. Fig. 12. Shell sub-ovate, widening posteriorly ; beak anterior incurved, umbo gibbous, with a gibbous umbonial slope on the posterior side, which is scarcely diverging from the cardinal line ; posterior extremity rounded, the basal margin arcuate, with a slight im- pression anterior to the middle, the anterior end a little gibbous. Surface cancellated by concentric and radiating elevated striae. It is not possible from the specimen before me to refer this species satisfactorily to any known genus. 25. Megambonia striata. N. sp. Shell somewhat oval, the basal and cardinal lines nearly parallel ; beak sub- anterior, small ; umbones convex, scarcely gibbous ; umbonial slope regularly convex, below which is a slight depres- sion reaching to the postero-basal margin ; posterior end rounded, fthe longer part of the curve on the basal side. Anterior end short and narrow, somewhat abruptly rounded. Surface marked by regularly radiating rounded striae with faint concentric lines of growth. This diflfers from the preceding species in being less gibbous, in the more nearly parallel cardinal and basal lines, in the direc- tion of the umbonial ridge, and in the stronger radiating strise. 24. AvicuLA HoNEYMANi. N. sp. Fig. 13. Left valve : body of the shell obliquely ovate, convex and somewhat gibbous towards the umbo, anterior wing small round- ed, posterior wing large triangular, obtuse at the extremity, ex- tending two-thirds the length of the shell. The line between the wing and body of the shell well defined by a slight abrupt de- presssion along the junction. Surface marked by rounded radiat- ing strise which are interrupted by fainter concentric undulations or lines of growth ; the wing is marked only by concentric striae. This species bears some resemblance to A. emacerata of the Niagara and Clinton groups of New York ; but its form is slightly more oblique, and the wing is marked only by concentric striae, ■while in the New York species the radiating lines on this part are stronger than the concentric ones. 154 Silurian Fossils of Nova Scotia. 25. MuRCHisoNiA Arisaigensis. N. sp. Shell teretely conical, volutions about five, gradually increasing from the apex, rounded with a slight angulation or carina in the middle. The surface is unknown and the angular band on the volution is the only means of determining its generic rela- tions. This differs from any of the described species of Murchisonia from American localities. 26. Murchisonia aciCulata. N. sp. Shell slender, very gradually tapering, volutions about six or seven, the last ones moderately ventricose, aperture elongate-oval or ovate, rounded at the anterior margin, columella plain ; volu- tions marked by a distinct band along the centre, and a sub-sutu- ral carina marking the upper side of the volutions; surface striated. Fig. 13. Fig. 15. Fig. U. ii 2?. HoLOPEA REVERSA. N. sp. Fig. 14. Shell small, sinistral ; spire depressed, volutions about three ; the two first small and gradually expanding, the last one rapidly expanding and ventricose ; aperture wide expanded ; suture im- pressed. Surface unknown. This shell has the general form of Holopea, but I have seen only a single specimen, which is a cast. It is remarkable and readily recognised from the sinistral spire. 28. Orthoceras punctostriatum. N. sp. Fig. 15. Shell slender, very gradually tapering, almost cylindrical; Septa distant about one third the diameter. Siph uncle central; section circular. Surface very finely striated with unequal undu- lating strisG, the interstices between which, are punctse which are oblong indentations often becoming confluent. Silurian Fossils of Nova Scotia, 155 This species is remarkable for its extremely gently tapering form ; the fragment of more than an inch long, showing scarcely a perceptible diminution in diameter. There are twelve and a half chambers in the space of one inch. The surface markings are peculiar, and among the species of the genus known to us constitute a distinctive character.* Fig. 16. 29. CoRNULiTES rLEXUosus. var. gracilis. This fossil resembles the one in the Clinton group of New York, but is somewhat more slender, and the annulations a little more closely arranged. The specimens from the rocks of New York present some variation in form, and the comparative dis- tance of the annulations. None of them, however, are so slender as the Nova Scotia specimens. 30. HoMALONOTus Dawsoni. N. sp. Fig. 17. Caudal shield somewhat parabolic, obtuse at the extremity, very convex, width at the anterior side greater than the length of the * The Arisaig beds afford at least three other species of Orthoceras. Cne, the largest of the three, has a marginal inflated siphuncle, and the septa about one-eighth of an inch apart, for a specimen two inches in diameter. It tapers very gently, and in all the specimens found is ellipti- cal in its cross section. It occurs in the upper series. A second, found in the lower series, is marked with strong annulations placed closely to- gether. A third, occurring in the upper series, and discovered since the specimens were submitted to Professor Hall, is a very beautiful species, apparently new, but closely resembling O. perelegans, Salter, of the Lower Ludlow formation. It is cylindrical, but slightly flattened ; septa very convex and one-twentieth of an inch apart in a specimen half an inch in diameter ; siphuncle central. Surface with slight rounded annulations from one-eighth to one-fourth of an inch apart, and covered with delicate transverse stria, scarcely visible to the naked eye, and about sixteen in a line. Under the microscope the striae appear as thin sharp parallel curved ridges, the spaces between being finely granulated and wider than the ridges. I would name this species 0. elegantulum. — J. W. D. 156 Silurian Fossils of Nova Scotia. axis. Axis wider than the lateral lobes, distinguishable (in casts) from the lobes by a bending of the ribs and a scarcely perceptible depression along that line ; annulations abruptly prominent ; seven on the lateral lobes and nine on the axis, the anterior ones bend- ing slightly backward at the line of division between the axis and the lateral lobe ; each successive one bending more and more abruptly till the last one approaches a rectangular turn ; the whole curving gently forward at their extremities, and all terminating abruptly before reaching the margin. Behind the seventh annula- tion the axis is marked by two more annulations, leaving nearly one-fourth of its length smooth. This species is described from the casts and impressions of the caudal shield, so that the crustaceous covering is unknown. It is readily distinguished by the broad not prominent axis, the rect- angular direction of the annulations on the axis, and their abrupt bending at the lateral furrow. An impression of a few imperfect annulations of the body shows that they are strongly elevated, much more so than in any known American species. 31. Calymene Bltjmenbachii. var. Caudal shield somewhat semicircular, axis very prominent, marked by about seven annulations, lateral lobes marked by five ribs the four anterior ones bifurcating. Surface granulose. The specimens are not sufficient to make any satisfactory determina- tions regarding specific difierences. Fig. IT. Fig. 18. 32. Dalmania Logani. N. sp. Fig. 18. The specimens are two or three imperfect cephalic shields, one preserving the palpebral lobes, and others consisting principally of the glabella, with two or three parts of caudal shields. There is a fragment of a cheek which may be of this species. Cephalic shield somewhat semicircular. Glabella ovate, wider in front and truncate behind, depressed convex ; occipital ring narrow, pro- minent ; occipital furrow bending a little forward in the middle and curving gently backward in the middle of each side, and Silurian Fossils of Nova Scotia. 157 again turning forward ; posterior furrows narrow and sliarply im- pressed, each one extending about one third across the glabella and curving forward at their outer extremities ; central furrow linear, obscure, having a direction transverse to the axis ; anterior furrow obscure oblique to the axis, linear, extending to the margin of the glabella a little forward of the eye ; frontal lobe regularly rounded anteriorly. A fragment of a cheek in the same associa- tion is broad, produced posteriorly in a short strong spine, and marked by a broad sub-marginal groove. Caudal shield somewhat semi-elliptical, convex, acute behind, axis very prominent, rounded and marked by about eight annulations, which are gently curved backward at the extremities ; lateral lobes with six simple flat- tened ribs which terminate in a thickened border, and separated from the axis by a strongly defined furrow ; extremity abruptly pointed. The glabella of this species more nearly resembles Phacops in the general form and faintly impressed furrows, of which the pos- terior one is conspicuous. The form of the palpebral lobe, and the absence of tubercles at the base of the glabella, together with the form of the caudal shield, ally it with Dalmania, and it may be compared with D. Phillipsi of Barrande, but has a more pointed caudal shield, and the cheek, if correctly referred, is prolonged in a posterior spine.* 33. Beyrichia pustulosa. N. sp. Fig. 19. Yalves unequally semi-oval, a little more than once and a half as long as wide ; surface marked by three prominent ridges ; cen- tral, anterior, and posterior. The central one is' a single oblong oval tubercle which is directly transverse to the dorsal margin and a little nearer the anterior side. The anterior ridge consists of a single highly elevated, rounded or papillose tubercle near the dor- sal margin, and an elongated elliptical tubercle placed obliquely near the antero-ventral margin, and in older specimens sometimes swelling and spreading over the margin. The posterior ridge rises near the dorsal margin, and making a slightly broader curve than the posterior end of the valve approaches the ventral margin at the centre : the ridge is high and angular with a small prominent • Attached to a fragment of one of these trilobites is a small Spirorbis. It is dextral, with two to three turns, and rounded concentric wrinkles on the last whorl. — J. W.

The central ridge or tuber- cle is separated from the lateral ridge by a distinct furrow, and its continuation from the base of the tubercle passes between the lower ends of the two lateral ridges. Ventral and lateral mar- gins with a narrow thickened rim. This species resembles very nearly the l^. tuherculata of Klo- den, as described and figured by Mr. T. Rupert Jones. In our specimens the dorsal angles are more rounded ; the posterior ridge at its base is never extended beyond the middle of the valve, and is marked on its crest by several small spine-like tubercles. The anterior ridge is usually more extended along the ventral margin in our specimens, aud the furrow is better defined, while the tubercles are never flattened above or overhanging the base as shown in the European specimens. Smaller specimens, which ap- pear to be the young of this species, present some slight variations of surface markings, but show less difiference than the young of B. tuherculata. Fig. 19. Fig. 20. 34. Beyrichia eqilatera. N. sp. Fig. 20. Nearly equilateral, very convex, marked by three smooth or nearly smooth ridges. The central ridge is an oblong tubercle reaching from near the dorsal margin a little more than half way to the ventral margin. The posterior ridge is a little larger, but scarcely differing in form from the anterior one, its ventral ex- tremity terminating beneath or a little in advance of the middle of the central tubercle. The furrow is narrow but well defined on the two sides of the central tubercle, and becoming shallow in its passage to the marginal furrow ; ventral and lateral margins thickened. 35. Leperdita sinuata. N. sp. Minute sub-ovate, anterior end narrow, dorsal line one-third shorter than the length of the valve ; an extremely minute tuber- cle near the anterior end. Centre extremely convex or ventricose ; ventral margin near the posterior end a little sinuous, or indented from the inner-side. Surface smooth under an ordinary lens.

Helopora feagilis, var. acadiensis. The specimens under examination offer no very important dif- ference from those in New York, and as the Nova Scotia examples have been more or less compressed and worn, they are scarcely in a satisfactory condition for nice discrimination. All the above fossils belong to the Arisaig series of Mr. Daw- son's paper. Nos. 4, 10, 30, 36 and 37 appear characteristic of the dark and olive shales of the lower member, in which are also StropTiomena profunda^ S. ruffosa, Orthis testudinaria, Atrypa emacerata, Khynconella equiradiata, Graptolithus Clintonensis, and crinoidal columns ; also a Modiolipsis allied to 31. subcari. natus. The remaining species are in the coarse limestone and reddish shale of the upper member, in which are also StropTio- mena corrugata, Atrypa reticularis , Rhynconella neglecta^ Lin- gula ohlongaj Bucania trilohita, and a Chmtetes or Steiwpora similar to that of the Clinton formation. Cornulites flexuosus is almost the only species which occurs equally in both groups of beds. Some of the CUdophori are also found in both groups. REVIEW. Notes of a Clerical Furlough, chiefly spent in the Holy Land, with a sketch of the voyage out in the Yacht "St. Ursula." By Robert Buchanan, D.D. Third thousand. Glasgow, Blackie & Sons: Montreal, B. Dawson & Son. pp. 437, with illustrative maps. This book is written by one of the most esteemed and accom- plished ministers of Glasgow, Scotland. It is the fruits of a voyage in the private yacht of Mr. Tennant, a wealthy manufao- 160 Review, turer of tliat city. The incidents of the voyage are most agree- ably related. The party landed at Alexandria in Egypt, and visited Cairo and the Pyramids, of which places the author gives most graphic descriptions. Returning to Alexandria, they went on to Jaffa — the ancient Joppa, the port of Palestine. From that place they journeyed to Jerusalem, At every prominent place, vivid and most interesting descriptive accounts are given of the physical appearances of the country, together with interesting notices of the historical events associated with the localites. In- stead of entering Jerusalem by the Jaffa Gate, the travellers took a detour to the Mount of Olives, which after much fatigue, they reached at night-fall, and spent a cold and comfortless night in an upper room in the Mohammedan Mosque. This, however, was the finest point for viewing the city and its environs. In the morning they descended the Mount, and wended their way along the road which the Saviour frequently traversed on His journeys to and from Jerusalem. The remarkable spots on this route, and the language of Scripture which they illustrate, are carefully noted. We have read nothing more artistic and eloquent than the descriptive parts of this entrance into Jerusalem, Having spent some time in the sacred city, and having visited the Dead Sea and the River Jordan, our travellers extended their journey northward through the classic ground of Samaria, on to the sacred Sea of Galilee. Here, with loving reverence and deep emotion, they linger among the scenes in which so many of the Lord's wonderful miracles w^ere wrought. They went on to Lake Merom and the sources of the Jordan ; and visiting Damascus, they then crossed the range of Lebanon, and examining the ruins of Baalbec, passed on to Tripoli, where they embarked again for home. "While this book aims only at a familiar narrative of •what was seen and experienced in Palestine, it yet exhibits an ex- tensive and accurate erudition. If not so elaborate, it is as accurate and critical as Stanley's. In his powers of impresssing the prominent features of a scene, with its most interesting accessories, vividly upon the mind of the reader, Dr. Buchanan excels any of the late writers on the Holy Land. We know of no more fascinating or delightful book of travels than this is, and would specially recommend it as most suitable for the family library. A. F. K. MONTHLY METEOEOLOGICAL REGISTER, ST.

Description. — Shell small, depressed-conical ; apical angle be- tween 80° and 90° ; whorls about three with a nearly circular section, regularly ventricose above ; obscurely carinated along the middle on the underside, suture distinct, umbilicus about one fourth the width of the shell, penetrating to the apex ; aperture circular. Surface with strong sharply elevated lines of growth, Silurian Fossils of Canada. 163 wliich on crossing the wliorl are deflected gently backwards until on approaching the base of the body whorl, they turn a little for- ward and pass vertically into the umbilicus. There are six strias in the width of one line. Width of only specimen seen five lines, height four lines ; width of aperture two and a half lines. This species differs from S. Circe in being much smaller, and in having the surface so strongly striated as to present a pecu- liarly rough file-like appearance ; only one specimen has been col- lected, but as it exhibits the aspect of a mature shell, I am in- clined to think the species is small. Locality and Formation. — Pauquettes Rapids, Ottawa River, Black River, and Birdseye, (apparently rare). Collector. — Sir W. E. Logan. The following species of Pleurotomaria have been usually referred to P. lenficularis, (Sowerby) but they all appear to be distinct from that species. Pleurotomaria Progne. N. s. Fig. 6. Fig. 6. — Pleurotomaria Progne. Decription. — Lenticular ; about one inch and a half in width ; spire depressed conical, apical angle about 140°, seldom more but often a little less ; surface of spire presenting an uniform nearly flat, smooth slope from the apex to the margin, the sutures in perfect specimens being scarcely distinguishable although in casts of the interior they are somewhat strong and deep. The margin is narrowly rounded and does not exhibit the acute edge possessed by such species as P. qualteriatus. On the under side the whorls are uniformly depressed convex and the base, or all that portion of the shell which lies below the margin, is usually nearly double the bulk of the spire. When perfect the umbilicus is completely closed, but in the casts of the interior, there is a small perforation. The aperture is transversely sub-oval, scarcely sub-rhomboidal 164 Silurian Fossils of Canada. and in perfect specimens the width must be nearly twice the height. There are about four whorls. The surface appears to be nearly smooth, but as the only specimens with the shell preserved, that I have seen are silicified, they do not exhibit it perfectly. This species differs from all those described by Hall in the Palseontology of New York in having the umbilicus closed and from the P. lenticularis and P. qualteriatus of the European authors, not only in the same respect, but also in having the mar- gin rounded instead of acute. Locality and Formation. — City of Ottawa; near Montreal; Belleville ; Trenton, and numerous other localities in Trenton Limestone ; good specimens extremely rare. Collectors.— ^iv W. E.

A section through the umbilicus. General form same as P. Progne, (see fig. 6) from which species it only differs in having an open umbilicus. Description. — Lenticular, one or two inches wide ; whorls four or five, nearly fiat above, elevated into a depressed conical spire with a nearly smooth continuous slope from the apex to the mar- gin ; the latter obtusely rounded. On the under side the whorls are moderately convex, forming a depressed conical base, the bulk of which is always somewhat greater than that of the spire. The umbilicus penetrates to the apex, and is in general somewhat less than one third of the whole width of the shell. The aperture is transversely sub-rhomboidal, the width about one third greater than the height. The surface is rarely preserved, but from such fragments of the shell as I have seen it must be nearly smooth or at least very finely striated. Silurian Fossils of Canada, 165 This is the most common species of Pleurotomaria in the Trenton Limestone, and is I have no doubt the same as that figured by Prof. Hall in the work above cited, but surely it can- not be the European species P. lenticularis to which it has been referred. That species has a sharp edged margin. There are several European species under the name P. lenticularis^ but it is the Silurian form to which I refer. P. rotuloides. — (Hall) has not the smooth spire, and concealed suture of P. Americana^ and there is no other in the Palaeonto- logy of New York, to which this species can be compared. It may be that P. Progne and P. Americana should be classified as one species, but at present I think the great difference in the um- bilicus is sufficient to separate them. Locality and Formation. — Trenton Limestone at Ottawa, Montreal, Beauport, Trenton, Belleville, and St. Joseph's Island, Lake Huron. Good specimens exceedingly rare. Collectors,— ^ir W. E. L.; A.M.; J. R.; E. B.; R. B. Pleurotomaria Helena. N. s. Fig. 8. Fig. 8. — Pleurotomaria Helena. Description. — Sub-lenticular, with an elevated narrowly round- ed margin ; spire depressed conical ; apical angle varying from 110° to 125°, apex rounded not acute ; whorls about four, the last one rather strongly concave on the upper side, the others only slightly so. On the underside of the shell the whorls are moderately con- vex, and the umbilicus closed. The aperture is a little wider than high, the upper part of the inner lip slightly indented by the body whorl, the lower half somewhat vertical, but rounded, the lower part of the outer lip from the umbilicus to the margin of the whorl gently convex, the portion above the margin concave. In most specimens the suture is enamelled, the shell appearing to be continuous from the apex to the margin, but in some, especially 166 Silurian Fossils of Canada those which are a little worn, it can be more rr less distinctly- seen ; the last whorl usually drops a little below the margin of the next preceding, but even in such instances the suture is not very distinct. In the specimens from shaly rocks no surface markings are visible, but in those from the sandstone of Anticosti, the striae are distinctly visible curving backwards from the suture to the margin. They are very fine in general, but there are occasion- ally a few coarse ones at distances of half a line or thereabouts from each other. Width from ten to fifteen lines ; height a little variable; usually about three fourths of the width. This species is evidently allied to P. calcifera, but differs there- from in having no umbilicus. Variety. — Associated with the specimens upon which the above description is founded are several others which have the last whorl on the underside obtusely angulated at about two thirds the width from the outside, this angulation forming the edge of a shallow concave umbilicus, about one third of the whole width of the shell but which does not appear to penetrate the spire more than half the depth of the last whorl. One of these specimens is nearly two inches wide, with the strongly elevated margin forming a spiral ridge quite to the apex, this character giving to the spire a more distinctly turretted aspect than is exhibited by the specimen above figured. It may be that these should constitute distinct species, but the fact of their hav- ing been found associated together both at Lake Huron and Anti- costi induces me to regard them as only varieties. Locality and Formation. — Cape Smith, Lake Huron ; Hudson Eiver Group ; and also in the same formation at Anticosti. Collectors. — J. Richardson and R. Bell. Ophileta Ottawaensis. N, s. Description. — About one inch wide ; whorls four or five ; an elevated sharp margin all round ; spire concave more or less de- pressed below the plane of the margin ; underside of whorls regu- larly ventricose; umbilicus wide, shallow, concave, exposing all the whorls, occupying all the space within the outer whorl. Sur- face not observed. Width of largest specimen seen fourteen lines ; width of last whorl at the aperture five lines ; depth of same four lines ; depth of concavity of spire in the centre nearly one line ; of umbilicus rather more than one line. The depth of the concavity of the Silurian Fossils of Canada, 167 spire varies greatly. A small specimen eiglit lines wide consisting of three wliorls lias the spire full two lines depressed below the margin the lower side being nearly flat. Fig. 9. Fig. 10. Fig 9. — Ophileta Ottawaensis. Front view partly shewing the depres- sed spire. 10. — View of the base. The specimen figured has the whorl more slender than they are in the majority of the individuals. In the geology of Kussia plate 23 Figs. 2a 2h De Verneuil and De Keyserling have figured a species almost identical with this, but they regard it as only a variety of Fleurotomaria qualteriatus. It appears to me however to be a distinct species. We have in the Trenton Limestone a number of species oi Pleurotomaria and in some localities the individuals (although rarely perfect) are not uncommon. Yet I have never seen any specimens that could be considered as intermediate forms between the one here described and those which belong to the group of P. qualteriatus. This species differs from 0. compacta Salter principally in having the umbilicus concave instead of flat. Locality and Formation. — City of Ottawa, Trenton; not com- mon. Collector. — E. B. Bellerophon Argo. (N. s.) Description. — Lenticular ; from half an inch to an inch and a-half in diameter, (usually about one inch) ; the dorsum with a rounded edge and the sides rather strongly and uniformly convex. Whorls three or four, each concealing about two-thirds of the one next preceding it. Umbilicus small, exposing all the whorls in a series of rectangular steps. Aperture not expanded, triangular, indented on the ventral side to about one-third its height by the dorsum of the penultimate whorl, the two sides gently convex uniting at the dorsal angle at about 80^ or 90^. Surface apparently not striated but often exhibiting some rough transverse undulations. 168 Silurian Fossils of Canada* Diameter of a specimen of the ordinary size fifteen lines ; thick- ness in the centre seven lines ; width of that portion of the umbi- licus which is formed of the last whorl three lines ; of the portion included in the penultimate whorl one line and one fourth ; width of aperture at the base eight lines ; height about the same. A small specimen nine lines in diameter is four lines and a-half in thickness at the centre ; umbilicus two lines wide ; aperture five lines wide at base and the same in height.

Description. — Lenticular ; compressed ; greatest thickness at the umbilicus about one fourth the diameter ; the dorsum acutely ? angular ; the sides gently convex next to the umbilicus, becoming somewhat flat or very slightly concave towards the circumference. Whorls two or three each concealing rather more than half of the one next preceding it. Umbilicus small exposing all the whorls in a series of rectangular steps. Aperture triangular, not expanded, indented on the ventral side to about one third its height by the preceding whorl ; the two sides gently convex uniting at the dorsal angle at an angle of about 50°. Surface apparently nearly smooth. Diameter of the only specimen examined one inch ; thickness at the umbilicus three lines ; width of umbilicus four lines. S'lhirian Fossils of Canada. 169 This species agrees exactly with B. Argo in all respects ex- cept in being only one half the thickness and in having the umbi- licus a little larger. It is also closely allied to B. acutus Sowerby but that species is, according to Sowerby and McCoy only six or seven lines in diameter and nearly half as much in thickness.

Fig. 14. — Bellerophon Charon, Side view. 15. — Front view. Description. — Sub-globular with a widely expanded aperture; diameter about an inch. Whorls about three each concealing half of the one next preceding it. Dorsum broadly rounded ; a scarcely perceptible angulation along the median line, on each side of which, especially towards the aperture the shell is in some speci- mens very slightly flattened. The umbilicus is deep, penetrating to the centre, exposing all the whorls, the inner ones only obscurely seen, owing to their being imbedded in those preceding them. The sides encircling the umbilicus narrowly rounded, not angular. The aperture is very much expanded transversely, widely auriculated on each side, the width being about three times the height ; the ventral side indented by half the thickness of the preceding whorl and the dorsal border apparently with a wide though not very deep emargination. The surface apparently nearly smooth or only very finely striated. Diameter of a nearly perfect specimen, measured from the mid- dle of the dorsal lip through the aperture to the opposite side, one inch ; width of aperture at base sixteen lines ; height of aperture, five lines ; width of last whorl at the entrance of the aperture, five lines ; diameter of umbilicus, three lines. A cross section of the 170 Silurian Fossils of Canada* wliorl would be elongate sub-oval (or owing to the indentation caused by tlie preceding wliorl, reniform) in the proportion of about two and a half to five. Allied to B. rotundatiis, (Hall) but that species according to the figures has the umbilicus full half the whole diameter, and the whorl angulated at the sides. In this species the umbilicus is about one fourth the whole diameter, and the whorls rounded at the sides. The aperture also in B. Charon must be proportionally much wider. There appears to be some variation in the proportions of dif- ferent individuals of this species, but as most of the specimens are mere fragments, the amount cannot be determined at present.

Soc. vol. 15, p. 376. 1859. This genus consists of short, thick, curved Orthoceratites, with a very large siphuncle, the smaller extremity of which is, for a short distance, filled with a solid secretion so organised as to exhi- bit the appearance of several hollow cones inserted one within another. The specimens upon which Mr. Salter founded the genus were imperfect and did not exhibit the true septa, but there are now in the collection of the Greological Survey of Canada two frag- ments of difibrent individuals of a species of this genus, with several of the septa well preserved, so that there can be no doubt of their existence. The discovery of these fossils, and also of Maclurea Atlantica in Canada, furnish an interesting additional proof of the value of organic remains in establishing the equiva- lency of widely separated deposits of rock. When Sir R. I. Mur- chison, in 1857, announced that certain beds of limestone in Scotland were of the age of the Calciferous Sandrock and Chazy formations of Canada and New York, the only evidence consisted of a few imperfect fossils, among which were an Ophileta, consi- dered by Mr. Salter to be either identical with or closely allied to the Canadian 0. compacta, together with a Maclurea of a new species and several Orthocerites, resembling in aspect those asso- Silurian Fossils of Canada* 171 ciated with the genera Opliihta and Maclurea in this country. Their Maclurea PeacJiii has a long spiral operculum, very unlike anything then known on this side of the Atlantic, and it was not suspected that the genus Plloceras would ever be found here at all. But we have now not only a species of Piloceras (from the Cal- ciferous Sandrock) but also Maclurea Atlantica (from the Chazy) which latter species has an operculum almost identical with that of 0. PeachiL When it is considered that evidence of this kind as it accumulates increases in its demonstrative power in a much higher ratio than do the mere number of the species (or the facts which constitute the data) the correctness of the view that the Scottish and Canadian rocks above referred to are of the same age, cannot fail to be perceived. Piloceras Canadense. N. s. Fig. 16. Fig. 16. — Side view of the solid portion of the siphuncle shewing distance of tlie septa. Description. — Of this species we have, besides several detached siphuncles, two fragments, each exhibiting some of the septa. The form, as nearly as it can be determined is that of a short thick curved Orthoceratite. The length of the largest specimen appears to have been about ten inches, and the diameter at the aperture four or five inches. The transverse section is oval, the narrowest side being that of the concave curvature. The siphun- cle of one specimen is, at two inches and three-fourths from the apex, seventeen Hues in diameter in the dorso-ventral direction, and fourteen lines in the transverse direction. On the surface of this specimen there are, on an average, six septal rings in the length of one inch. Judging from the appearance of another spe- 172 Silurian Fossils of Canada. cimen, the position of this siphuncle would be close to the ventral side of the shell. Another siphuncle about the same size shows seven septal rings to the inch. In a third, consisting of a portion of the larger extremity of an individual which, when perfect, must have been at least nine inches in length, there are six septa partly preserved apparently those next the aperture. They are dis- tant from each other about five lines, the whole being com- prised within a length of thirty lines. The shell where these septa are situated is at least four inches in diameter in the transverse direction, and the siphuncle about two inches. The edges of the septa, in crossing the ventral or concave side, make at the surface a short curve towards the apex, but on the siphun- cle the septal ridges cross from the dorsal to the ventral side ob- liquely, so that on the ventral side they are somewhat nearer the aperture than they are on the dorsal side. The above are all the details of this species of any importance furnished by our specimens. On comparison with Salter's P. in- vaginatum, it will be seen that the septal rings do not cross the siphuncle in the same direction as they do in ours, and further, that that species is more broadly curved.

Description. — Small, slender, slightly curved ; section circular. One of the specimens examined is three lines in diameter at the aperture and apparently a little less at one line and a half above. The shell then expands to a diameter of four lines at the distance of five lines from the aperture. It then tapers to two lines at a Silurian Fossils of Canada, 173 length of thirteen lines ; thence to the apex unknown, but proba- bly terminated at a length of eighteen or twenty lines. One side of the fragment is nearly straight. No septa or siphuncle observed in this specimen, but the form alone is sufficient to distinguish the species from any other known in the Lower Silurian of this country. Associated with the one above described was found an- other fragment ten lines and a half in length. Width at aperture three lines ; diameter at five lines from aperture four lines ; length of chamber of habitation five lines and a half Next to the cham- ber of habitation five of the septa are preserved and they occupy a length of exactly five lines ; the siphuncle not visible.

Aperture of a specimen. 20.*-Side view of a different individual. Description. — Ventral aspect with the convex curvature ; dor- sal aspect concave ; section oval narrowly rounded on the ventral aspect; depressed convex on the sides and broadly rounded on the dorsum. In the first inch and a half of the length the ventral side forms a curve of which the radius is about one inch ; the re- mainder of the curve to the apex unknown. The aperture is broadly rounded on the dorsal side; at about one third the dor-< so-ventral diameter it begins to contract ; at two thirds its diame- ter its transverse width is about half its greatest width ; thence to the ventral margin the sides are sub-parallel, gradually approach- ing each other ; the ventral margin narrowly rounded. On a side view the dorsal two thirds of the aperture is obliquely truncatedi 174 Silurian Fossils of Canada, towards tlie apex wliile the ventral tliird slopes so as to form an obtusely rounded right angle with the dorsal two thirds. The aperture is thus obscurely trilobed, the ventral lobe being the smal- lest and forming a deep narrow sinus in the ventral margin. At the aperture the greatest transverse width is six lines in the spe- cimen on which the species is founded ; the dorso-ventral diameter eight lines. At seven lines (from the most prominent point of the aperture on the side) we find the greatest transverse diameter which is here seven lines and a half and the dorso-ventral diame- ter nine lines. At the length of one inch and a fourth the dorso-ventral diameter is reduced to between five and six lines. The remainder of the specimen is not preserved. The depth of the chamber of habitation is ten lines. The first five septa occupy six lines of the ventral margin, but at the middle of the lateral aspect four lines and a half, Siphuncle about one line in diame- ter and apparently in contact with the shell along the median line of the ventral side. The surface of the shell is covered with fine stride or rather small smooth continuous wrinkles which encircle the tube following the curves of the aperture. These wrinkles vary in size, but in general there are five or six in the width of one line. The majority of the species of this genus have the siphuncle on the inside or close to the shell on the side of the concave curva- ture. M. Barrande, however, has one species P. perversum in which it lies close to the outer curve,* The aperture is not so strongly trilobed as it is in Upper Silurian and Devonian species. I believe this is the only Phragmoceras known in the Lower Silurian Rocks. Locality and Formation, — The specimen figured was found on Le Cloche Island, Lake Huron, in the Black Eiver Limestone.

Siplmncle very small, close to the ventral margin sliglitly dilated between the septa ; of these latter there are six in three lines where the transverse diameter of the shell is five lines. The dimensions of the best preserved specimen that I have seen are as follows. Length of specimen twenty-two lines ; transverse diameter of aperture seven lines ; dorso-ventral diameter of aper- ture five lines ; depth of chamber of habitation, twelve lines ; transverse diameter at smaller extremity of specimen four lines nearly ; dorso-ventral diameter three lines nearly. In the length of twenty-two lines measuring from the aperture this specimen tapers three lines in the tranverse diameter and one line in the dorso-ventral diameters. The width of the siphuncle between the septa is about three-fourths of a line ; its passage through the septa is a small circular aperture scarcely one third of a line in diameter. At the smaller end of this specimen the greatest trans- verse width is about one fourth the dorso-ventral diameter from the ventral margin. The aperture is more nearly a regular oval. The siphuncle is in the middle of the ventral aspect. The shell is gently curved towards the dorsal side. This species is related to both 0. xijjMas and 0. Jiastatum, (Report for 1856, p. 318 and 333) but the proportions are very difierent. In 0. xipkias the two diameters of the aperture are to each other as 7 to 3, but in 0. tener they are as 7 to 5. 0. hastatum tapers at the rate of about 4 lines to the inch, while in 0. tener the rate is scarcely two lines.

Description. — The specimen on which this species is founded is two inches and five lines in length ; nine lines in diameter at the larger and seven lines at the smaller extremity ; section cir- cular ; septa distant three lines at the large end and two lines and a-half at the small end. The siphuncle is moniliform its centre distant two lines from the marsrin where the diameter is seven lines ; the expansions are sub-globular and about two lines or a little more in their greatest diameter.

The probable length of this Orthoceras judging from seve- ral imperfect specimens which I believe to belong to the species is from one foot and a half to two feet. The surface exhibits some indistinct flat longitudinal ridges, each about one third of a line wide and half a line distant from each other. Locality and Formation. — Pauquettes Kapids, Ottawa River, Black River limestone. Collector. — Sir W. E. Logan. Orthoceras rapax. N. s. Description. — Large, section circular, septa distant a little less than one fourth of an inch where the diameter is between five and six inches. Siphuncle large, marginal very nearly in contact with the shell on the ventral side. The rate of tapering appears to be about one inch and a half to the foot. The depth of the chamber of habitation is about one half greater than the width of the aper- ture. Of this species we have portions of two individuals. One is a fragment of the oral extremity entirely deprived of the shell, and exhibiting a good cast of the interior of the chamber of habitation. The following are the dimensions. Length fourteen inches; diameter at aperture six and a half inches ; at fourteen inches from aperture, four and three fourths inches ; diameter of siphuncle one inch and three fourths at the broken or smaller end of the speci- men ; the first twenty one septa occupy a length of four inches and seven eighths. The second specimen is fifteen inches and a half in length, and tapers from six inches to four as nearly as can be determined. In the first five inches of the smaller extremity there are twenty septa ; in the next inch five ; in the next inch and a half twelve, and in the remainder from four to seven in the inch. The distance of the septa is thus variable in the same specimen, but judging from the general appearance of the two examined, my present impression is that the average distance must be from two and a half lines to three lines, or a little less than one fourth of an inch at a diameter of from four to six inches. The proportional distance of the septa to the diameter of the shell therefore would be about as twenty to one. Notices of the Life of Professor Wilson, 177 This species clearly belongs to the same group with those which Professor Hall has figured under the name of Endoceras protei- forme, in the 1st Vol. of the Palaeontology of New York. But on measuring the figures in that work it will be seen that the pro- portional distance of the septa to the diameter of the shell in that species is between four and eight to one or six to one on an ave- rage while in this species it is twenty to one.

The University of Edinburgh has lately sufifered severely by the death of several of its most distinguished teachers. The depart- ment of science has been specially unfortunate. Since the death of the venerable Jamieson, Professor Forbes, whose fine genius and extensive erudition gave promise of an illustrious life, has been laid in the sepulchre of his fathers ; and ere yet his country, and we may say the world of science, had ceased to mourn for this most gifted of her children, another equally honorable and beloved has been laid in the dust. The name of Professor George Wilson, whose recent appointment as Regius Director of the Industrial Museum of Scotland and to the professorship of Technology in the University of Edinburgh was hailed with so much satisfaction by all who had any acquaintance either with his personal char- acter or numerous contributions to literature and science, will we are sure be held in lasting and affectionate remembrance. The most complete notice of his life and works which we have yet seen is that contained in the February number of the North British Review. The article is preceded by a list of no less than sixty eight of his writings. They comprise original papers on chemistry, biographical sketches of men eminent in science, seve- ral contributions to popular and scientific literature with four poems published in Blackwood's Magazine. The ability, research, Can. Nat. 2 Vol. V. 178 Notices of the Life of Professor Wilson, and true genius which all those writings display, will ever give the name of George Wilson a high place among the illustrious dead We are sure it will be grateful to those of our readers who may not have access to other sources of information to be ut in possession of the following particulars of his history. Dr. Wilson was born in Edinburgh, on 21st February 1818; and was thus, at his death, in the forty-first year of his age. " His parents were highly respectal>le, though not in such an elevated station as to diminish the credit due to his own exertions in attaining the position which he ultimately reached ; but it deserves to be noticed, that he may be included in the number of distinguished men who have been in a great degree indebted for the development of their talents to the maternal character and influence." His father, Mr. Archibald Wilson, was a wine merchant in Edinburgh, and died about sixteen years ago. His mother, Janet Aitken, who is still living, was the youngest daughter of a land- surveyor in Greenock. She was a lady of great intelligence and piety, and she devoted much attention to the education of her children. There were eleven of the family; but of these only three now remain, — a son, Dr. Daniel Wilson, the well-known author of "The Prehistoric Annals of Scotland," at present Pro- fessor of English Literature and History in the University of Toronto, — and two daughters. From his childhood, George was distinguished by many noble qualities — great truthfulness, self- sacrifice, delicate sense of honour, and generous feelings. Studious, and with a marked love for books, he gave early promise of great mental ability. In 1822 he commenced his studies in a private school, and in 1828 he entered as a pupil of the High School, under Mr. Ben- jamin Mackay, an able classical teacher. He was always among the first five in the class, and was remarkable for his general hnowledge — a quality which was exhibited during life, and which seemed afterwards to fit him specially for the situation he occu- pied in the University. So warm were his aff"ections, and such his power of attracting others, that from his boyhood onwards no one was more generally beloved. While at school, in 1828-29, he and his brothers formed among their companions a " Juvenile Society for the Advancement of Knowledge." They met once a week in his father's house, when papers were read on natural Notices of the Life of Professor Wilson, 179 history, meclianics, astronomy, etc. Minutes of their proceedings were kept by his brother Daniel. His mother presided over th^ youthful assembly, and usually wound up the evening by giving a verse from Proverbs. Wilson remained at the High School until he was fifteen. On leaving it he selected Medicine as his object of study, and com- menced by becoming an apprentice in the laboratory of the Royal Infirmary, where he remained for four years. The suffering and distress which he witnessed during this period, made an indelible impression on his very sensitive nature, and had a saddening effect on his mind. Many are the stories which might be told illustra- tive of his sympathy with the patients, and his eager desire to- relieve them. He entered the University of Edinburgh in 1834, passed as surgeon in 1838, took his degree of Doctor of Medicine in 1839, and wrote a thesis " On the Certain Existence of Haloid Salts of the Electro Negative Metals in Solution." After taking his degree, chemistry became his favourite pursuit. He had studied the sub- ject assiduously under Dr. Hope and Mr. Kenneth Kemp; and in 1836-37 he had been engaged for eighteen months as chemical assistant in Dr. Christison's laboratory, which was at that time the best school of analytical chemistry in the University. His first lectures on chemistry were given to private audiences, in the drawing-room of his father's house, in 1837. In a MS. journal kept by hira, we find the following entries : — "September 20thj^ 1838" — " I meet with scarcely one lady in ten or fifty, who has sufficiently cultivated her natural intellectual powers." . . . "This winter shall see me do my utmost to suggest an improvement among my own small circle." " May 1 839. Following out the proposal to amend the subjects of ladies' conversation and study, I assembled some of them in my father's house, and delivered a course of prelections on che- mistry, especially the chemistry of nature. This was in the win- ter of 1837-38, so that I was then not nineteen. The majority of my audience were older than myself by a year or two. I was greatly praised and encouraged, most kindly listened to, and assisted in many ways, especially by J. M'G., a generous, unselfish, happy fellow, without whose aid I should have come on very poorly. This course, which began in October, was first interrupted by the illness of my sister, and afterwards by the mournful indis- 180 Notices of the Life of Professor Wilson, position of my cousin C. ; so tliat only ten or twelve lectures were given. Subsequently to this Dr. Wilson went to London, and entered the laboratory of University College, under the superintendence of Professor Graham, now Master of the Mint. There, with Dr. Lyon Playfair, Mr. James Young of Glasgow, Dr. Livingstone, the African traveller, and other zealous students, he carried on his chemical pursuits for a period of six months. He began to lecture publicly on chemistry in Edinburgh in 1840. About this time, however, his health began to suffer, appa- rently in consequence of excessive exertion during a pedestrian excursion in the Highlands with a cousin. His first course of lectures was arranged when he was confined to bed, and he was scarcely convalescent when he commenced the session of Novem- ber, 1840. His health continued broken after this. An attack of rheumatism was followed by disease of the ankle-joint, which ultimately called for amputation. This was performed in January 1843, by his friend, and afterwards his colleague, Professor Syme. Amputation seemed to offer the only hope of relief, and Mr. Syme proposed disarticulation. Accordingly, he performed this oper- ation ; and as the articulating surfaces of the joint were everywhere divested of cartilage, rough and carious, instead of removing the malleolar projections separately, he exposed the bone suflBciently to saw off both together, with a thin lamina of the tibia connect- ing them. This was the first instance in which Professor Syme amputated through the ankle-joint for disease of the joint. It is therefore interesting in the annals of surgery. The case proceeded favourably. The feelings which Dr. Wilson experienced previous to the operation, and during its performance, are graphically por- trayed by him in a letter on " the Anaesthetics of Surgery," which he addressed to Professor Simpson, and which is published in Simpson's Obstetric Works, edited by Drs. Priestley and Storrer, Vol. H., p. '796. He contrasts the condition of patients in his day, before the use of chloroform, with their state at the present time : — " Several years ago," he says, " I was required to prepare, on very short warning, for the loss of a limb by amputation. A painful disease, which for a time had seemed likely to yield to the remedies employed, suddenly became greatly aggravated, and I Notices of the Life of Professor Wilson, 181 was informed by two surgeons of the higliest skill, who were con- sulted on my case, that I must choose between death and the sacrifice of a limb, — and that my choice must be promptly made, for my strength was fast sinking under pain, sleeplessness, and exhaustion. I at once agreed to submit to the operation, but asked a week to prepare for it, not with the slightest expectation that my disease would take a favourable turn in the interval, or that the anticipated horrors of the operation would become less appalling by reflection upon them ; but simply because it was so probable that the operation would be followed by a fatal issue, that I wished to prepare for death, and what lies beyond it, whilst my faculties were clear and my emotions were comparatively undisturbed. For I knew well that if the operation was speedily followed by death, 1 should be in a condition, during the interval, in the last degree unfavourable to making preparation for the o;reat chano^e." During the interval, he diligently and prayerfully studied the Bible, and at the end of a week the operation was performed. There were no anaesthetics in those days, and the operation was a very painful and somewhat tedious one. Not being gifted with great physical courage, he was one of those to whom cutting, bruising, burning, or any similar physical injury, eren to a small extent, was a source of suffering never willingly endured, and always anticipated with more or less apprehension. He states that he could never forget the black whirlwind of emotion, the horror of great darkness, and the sense of desertion by God and man, bordering almost upon despair, which swept through his mind and overwhelmed his heart. Chloroform would have been the greatest boon to him. From his relations he concealed the impending operation, fearing that the expression of their grief would shake his resolution. They were not aware of what had happened until the surgeons made it known to them. " During the operation," he continues, "in spite of the pain it occasioned, my senses were preternaturally acute ; I watched all that the sur- geons did with fascinated intensity. I still recall with unwelcome vividness the spreading out of the instruments, the twisting of the tourniquet, the first incision, the fingering of the sawed bone, the sponge pressed on the flap, the tying of the blood-vessels, the stitching of the skin, and the bloody dismembered limb lying on the floor." He then dwells on the value of ancesthetics, and con- 182 Notices of the Life of Professor Wilson. clades tbus : — " The sum, you will perceive, of what I have been urging is, that the unconsciousness of the patient secured by anaesthetics, is scarcely less important than the painlessness with which they permit injuries to be inflicted on him." Forbes was an older student than Wilson, and had attained eminence as a rising naturalist before their acquaintance began. He was a genius in science who had the wonderful power of attracting followers, and of stimulating to exertion. Forbes' influ- ence told in no small degree on the mind of Wilson, who afterwards undertook to write his Biography. This work occupied his leisure hours ever since the lamented death of his friend ; but we fear that little more than half the task has been completed. In a MS. note-book, the chapters of the Life of Forbes are sketched out thus : — 1. Isle of Man. 2. Boyhood and School Life. 3. London Artist Life. 4. The University of Edinburgh. 5. The Student Life of E. F. 6. The Sea Naturalist. 7. The Mediterranean Cruise. 8. The London Chair of Botany. 9. The Geological Survey. 10. The Edinburgh Class of Natural History. 11. The Artist and Litterateur. 12. The End. 13. Epilogue. — Of these the first five chapters are ready for the printer, and the sixth seems also to be finished, though not copied out. As the materials have all been accumulated, it is earnestly hoped that the work may be completed by other hands. Up to manhood the vigour and elasticity of his health was unusual ; but from the year 1842 to the end of his career, a thorn in the flesh never ceased to buftet him. It was during this illness that his attention was specially directed to matters of eternal mo- ment. The bed of affliction was made to him a blessing. The chastening of the Lord was for his profit. There happened at that time to be a student at the Divinity Hall who became acquainted with Dr. Wilson, and was a constant visitor at his house. This was the present Rev. Dr. Cairns of Berwick. The friendship which sprung up between Dr. Cairns and himself was of the warmest kind, and continued throughout the remainder of life. Their fellowship was cemented by holier ties than any of a mere earthly nature. Dr. Wilson always regarded Dr. Cairns as his spiritual father, whose counsels encouraged him, and whose ministrations at the hour of death helped to cheer his spirit. What he owed to God's discipline during his life was ever grate- fully present to his mind. Notices of the Life of Projessor Wilson, 183 His recovery from his severe illness was tedious, and lie was rendered unfit for public duty for some time. His father died very suddenly in April 1843, and this added not a little to his sufferings. The commencement of Dr. Wilson's career as a lecturer was thus also that of his ill health. His weak body seemed often to be sinking into the dust, while his noble spirit ignored its fetters, and seemed to rise above the feebleness of the flesh. For fifteen years he continued to teach as a private lecturer, and he acquired eminence and celebrity. In 1844 he was appointed by the Direc- tors of the School of Arts their lecturer on chemistry ; and in the same year, with the sanction of the Highland and Agricultural Society, he became lecturer in the Veterinary College of Edin- burgh. Between 1844 and 1852 he continued to deliver regularly nine lectures on chemistry every week during the six winter months, and at a later period of his history he even delivered thirteen. Dr. Wilson had a peculiar power of making science- popular, and describing intricate subjects in such a way as to make them plain to a common audience. His inventive powers in illustrating his lectures were remarkable. His graceful diction and aesthetic taste, combined with his play of fancy and of genial wit, gave peculiar attractions to hisprelections, and crowded audiences hung on his lips whenever he appeared in public. In the Academic Hall, the Philosophical Institution, the learned society, and in the miserable lecture-room in the Cowgate or the Canongate, he was equally at home and equally successful. The attention which he devoted to economical science, and to the applications of chemistry, pointed him out as the man best qualified to occupy the situation of Director of the Industrial Museum of Scotland. In the autumn of the same year he was chosen by the Crown to fill the newly-insLituted chair of Techno- logy in the University of Edinburgh. The duties of this unendowed chair he fulfilled with the greatest ability and success. Although the class was not demanded for any academic honours, and was not included in any curriculum of study (except that of the Highland Society), still the talents of the Professor secured a large attendance. At the time of his death (although the entrance was not completed) the number of pupils was eighty-four, embracing students from all the Faculties and many amateurs. Nothing could more plainly indicate the 184 Notices of the Life oj Professor Wilson, value put on liis lectures. In his inaugural lecture be considere tte subject, What is Technology ? and he thus writes : "Techno- logy is the sum or complement of all the sciences which either are or may be made applicable to the industrial labours or utilit- arian necessities of man. While the subject has a connection with various subjects already taught in the University, it steers a course distinct from all, has a province of its own, and will not, when properly handled, interfere with the duties of any other professor." The full course of technology embraced three sessions, in each of which certain of the industrial arts were made the subject of lecture, which were not discussed in the other two. The course was divided into Mineral, Vegetable, and Animal Technology. Under the first were included the relation of the atmosphere, the ocean and tributary waters, and the earth, to technology; and among special subjects, fuel, building material, glass and glass- making, pottery, earthenware, stoneware, and porcelain, metallo- techny, electrotechny, and magnetotechny. Under the second or Vegetable Technology, were considered : saccharoamylaceous sub- stances, sugar-making, albuminous substances and fermentations, distillation, wood and wood-fibres, textile tissues, bleaching, dyeing calico-printing, paper-making, scriptorial or graphic industrial arts, caoutchouc, gutta-percha, and the resins, fats and oils. Under the third section, or Animal Technology, were included the me- chanical application and chemical products of bones, ivory, horns, hoofs, tortoise-shell, shells, and corals; skins, tanning, fish- scales ; hair, fur, wool, bristles, quills and feathers, animal refuse. The lectures were fully illustrated by experiments and drawings, and by specimens from the natural history collections and the Industrial Museum. Occasion was taken throughout the course to visit various manufactures. Besides occupying these important positions in the University and in the Museum, Wilson was also an active member of many societies, and contributed papers to their Transactions, as will be seen by referring to the list of his publications. He was twice elected a member of Council of the Royal Society of Edinburgh ; he was a member of the Council of the Chemical Society of Lon- don ; a member of the Chemical Committee of the Highland and Agricultural Society, and one of the examiners for the Agricul- tural Diploma ; an honorary member of the Pharmaceutical Society of Great Britain ; and he had been twice president of the Notices of the Life of Frofessor Wtlson, 185 Royal Scottisli Society of Arts, and for some time editor of its *' Transactions." A growing holiness, sweetness, and patience, bad been marked- ly visible in Dr. Wilson of late years. In times of sickness and dangerous illness, there was ever a serene calmness and cheerful- ness, that seemed greatly to aid recovery. His patient endurance of suffering was remarkable. Patience wrought experience, and experience hope — even that hope which maketh not ashamed. He was always ready for his great change. About six months ago, when saying good bye on a morning visit to a friend, he said, " I am trying to live every day, so that I may be ready to go on an hour's notice." To another he used the remarkable expression, " I am resigned to live." His feeble health at the commencement of the Session 1859 was ill calculated to fit him for the arduous duties he had under- taken, and there seemed to be in his own mind a feeling that he was not likely to survive long. In the last few days of his life his serenity was more obvious than at any previous time. So well was it known that, living or dying, he was the Lord's, that the anxieties of a death-bed season were as much lightened as is possible in this life. His death was more like a child going to sleep than anything else. He commenced his lectures in November 1859 with high pros- pects of success. His introductory lecture was characterised by his usual felicitous illustrations, and the class-room was crowded to the door. His last illness began from exposure to cold and wet in a ma- nufactory in the west, on the morning of Friday, 4th November. He had gone there to acquaint himself with the particulars of a Court of Session case relating to the dyeing mauve-coloured silk. On the morning of Friday, 18th November, he complained of a pain in his side, but he treated it as a pleurodynic attack, and went to lecture as usual. He was, however, much exhausted ; and in spite of this he continued to write letters, receive visitors and make business calls, and he even ventured to give a second, lecture in the afternoon. This seemed to prostrate him complete- ly, and he had to apologise to the class for taking a seat in place of standing during the lecture as usual. When he reached home he was scarcely able to get up stairs to bed, from whence he never rose. 186 Notices of the Life of Professor Wilson. On the morning of Tuesday, 22d November, there appeared to be a slight alleviation of symptoms, but it was a temporary rally. Ere long it was evident that he was sinking. He was peaceful and happy, when he breathed his last. The respect and affection with which he was regarded were well shown in the public funeral, which was attended by Professors of the University, the Lord Provost, Magistrates, and Council, the Colleges of Physicians and Surgeons, members of the Royal So- ciety, Royal Scottish Society of Arts, Royal Physical Society, Botanical Society, Philosophical Institution, School of Arts, Mer- chant Company, Chamber of Commerce. His friends, the Rev. Dr. Alexander and the Rev. Dr. Cairns, officiated on the occasion. His remains were interred in the Old Calton Burying-ground on 28th November, and his funeral sermon was preached by Dr. Alexander, in the Music Hall, to an overwhelming audience, on 4th December — the text being, " Blessed are the dead that die in the Lord," Rev. xiv. 13. While Wilson's lectures threw a genial light on the facts of science, his writings contributed not less to extend and popularise them. Everything he touched became instinct with life, and was impressed upon the mind of the hearer or reader by associations of the most pleasing and lasting nature. His collected writings will undoubtedly be an important contribution to literature. " The effort of his life." Dr. Cairns remarks, " was to render science at once more human and more divine. His heart was strung throughout in sympathy with the touching prayer of the Novum Organon^ that all science may become a healing art ; and his last public office was regarded by hitn with special affection, as ministering to industrial progress and happiness. No scientific writer of our day has so habitually and lovingly quoted the Bible, from his essay on Dalton, whom he represents as proving that God literally ' weighs the mountains in scales, and the hills in a balance,' down to his last paper, which closes with marking the identity of Professor Thomson's astronomical proof of the evanes- cence of the heavens with the words of the 102d Psalm. He hoped to live to write a 'Religio Chemici,' corresponding to Sir Thomas Browne's ' Religio Medici,' and embracing amongst other topics of discussion the doctrine of the resurrection." " To have moved, amidst the altitudes and solitudes of science with a humble and loving heart ; to have spoken out words on Notices oj the Life of Professor Wilson. 1 87 the sacredaess of medicine as a profession and scientific life in general, more lofty than have alraost been heard even from the pulpit, and to have illustrated them in practice ; to have enforced the subjection of all knowledge to one Name, the highest in earth and heaven ; to have conquered by faith in a life-long struggle with pain and suffering ; and to have wrought out the work of the day placidly and devoutly till the night came; — these, in any, and especially in the leaders of science, are processes and results greater than can be described in the transactions of any society, or preserved in any museum." AVc conclude these notices from the North British Review with a beautiful tribute of affection from the pen of his brother Dr. D. Wilson of Toronto, published in the *' Canadian Journal," for March. " Death has been busy of late among Edinburgh men whom I counted my personal friends. Dr. Samuel Brown, Professor Ed- ward Forbes, and Hugh Miller, have followed one another to the grave within a brief period, and ere the past year drew to a close. Dr. George "Wilson was added to the number of those who live only in honored memory. Dying at the early age of forty-one, when a career full of rich promise appeared only opening before him, and his mind seemed to be ripening in many ways for a great life-work : those who knew his capacity and his genius regard all that he had accomplished as insignificant indeed when compared with what he would have done if spared to those years in which men chiefly fulfil the promises of youth. Yet what he did accom- plish, amid many and sore impediments to progress, is neither poor nor of small amount. Nor is it a light thing now to remember that one whose years of public life have been so few, and even these encroached on by the ever increasing impeiiments of failing health, has been laid in his grave amid demonstrations of public sorrow such as have rarely indeed been accorded, in that native city of his, to Edinburgh's greatest men. This was due even more to the genial kindliness and worth of a noble Christian man, than to the unwearied zeal of a popular public teacher, and an enthusiastic student of science. His loss to his university is great, but to his friends it is irreparable. In him the faith of science, and the nobler faith of the Christian, were blended into perfect harmony : for no doubt springing from half-revealed truths of science ever marred the serene joy of his faith while looking at 188 Tertiary Fossils of Canada, ^r. tlie things which are not seen. Prejudice and falsehood, ignorance and vice, were felt by him to be the common foes of both ; and pardon me, if I add, that no man I have ever known carried more genially and unobtrusively, yet more thoroughly, his earnest Christian faith into all the daily business and the duties of life. When a man of such genuine kindliness and worth is suddenly called away in his prime, with still so much of his life-work seemingly waiting its accomplishment, it is as when a brave vessel founders in mid-ocean. The wild eddy of the troubled waters gathers around the fatal gulf, and a cry of sympathetic sorrow rises up as the news is borne along to distant shores. But the ocean settles back to its wonted flow where that gallant bark went down, and the busy world soon returns to its old absorbing occu- pations. But there are those to whom that foundered bark has been the shipwreck of a life's hopes ; and to me the loss of my life-long friend and brother will make life's future years wear a shadow they could never wear before." ARTICLE XV. — Notice of Tertiary Fossils from Labrador ^ Maine, <£'c., and Remarks on the Climate of Canada in the Newer Pliocene or Pleistocene Period. By J. W. Dawson, LL.D., F.G.S. {Read before the Natural History Society.) I am indebted to Capt. Orlebar, R.N., for a small collection of fossils from the vicinity of Tertiary Bay on the coast of Labrador a locality in which similar collections were made several years since by Adm^ Bayfield. They occur in clay a little above high water mark ; but the species present indicate a considerable depth at the time of the deposition of the bed in which they are contained, so that it cannot properly be regarded as merely a raised beach. The species contained in the collection are as follows; those found in the newer Pliocene of Canada bein^ marked with asterisks. Balanus porcatus.^ Spirorhis vitrea, attached to shells.* Sp. carinata. Buccinum undatum.^ Tertiary Fossils of Canada, Sfc. 189 Aporrhais occidentalis. Natica, (fragment probably oi N. Clausa.)* Saxicava rugosa, var. Arctica.^ TelUna proximaj (calcarea) ^^ Astarte elliptica, • Rliynconella psittacea.^ Echinus granulatus. Hippotlioa catenularia, (attached to shells) * Lepralia pertusa.^ L. (not determined.) Cytliere. The greater number of the above species have already been recognised in the tertiary clays of Canada ; * but the following exceptions are deserving of notice. Spirorbis vitrea^ has not been named in my previous papers ; but I now find, on comparison with the specimens from Labrador and recent examples from Gaspe, that it is this and not Spirorbis sinistrorsa as previously stated, that occurs in the tertiary beds at Montreal and Quebec. It is at present a deep water species in the Gulf of St. Lawrence and on the banks of Newfoundland. Spirorhis carinata has not previously been observed in the ter- tiary beds ; but is common on the coast of Labrador and Gaspe.f Aporrhais occidentalis, the American representative of the ^* Pelican's-foot Spout-shell" of Britain, and remarkable in the adult state for its singularly expanded outer lip, is a deep water shell somewhat widely though not very abundantly distributed on the American coast. I have specimens from Labrador, Sable Island, and Portland, where a very fine living specimen was dredged for me last summer by Mr. Ferrier. Saxicava rugosa, occurs in the Labrador collection under the form described as S. Arcticahj Forbes and Hanley. This form is not prevalent though sometimes seen among the Saxicavoe of the St. Lawrence valley deposits, and at present is I think found only in deep water. The intermediate specimens prove it to be merely a variety of the common species. Astarte elliptica is the common Astarte of the Gulf of St. * See papers by the author in Canadian Naturalist, Vols. 2 and 4. t See paper on Spirorbes of the Gulf of St. Lawrence in last number of this Journal, 190 Tertiary Fossils of Canada, ^c, Lawrence at present. Great numbers have been dredged by Mr Bell on the coast of Gaspe in about 60 fathoms. Along with them are found a few specimens having the characters of the typical Astarte sulcata of Great Britain, and others having the charactei's of A. compressa^ a species much more nearly related than the others to the fossil A. Laurentiana, though quite distinct. I can recognise in the collections made by Mr. Bell and myself all the above species or varieties, and in addition the A» Arctica, which I have found only in the pleistocene beds near Port- land. A. Laurentiana and A. Arctica are without doubt distinct species from Sulcata, but different views have been entertained as to the others. The distinction based by some authors on the crenulated or smooth margin, and on which the species A. Scotica and A. Danmoniensis have been founded, is evidently worthless, depending as it does on age ; but the distinctions of external form and marking are apparently constant at all ages, and do not shade into each other. Althouoh therefore Dr. Gould and Mr. Stimpson retain the name sulcata for all our American forms, I think it admits of a doubt whether the same distinctions made by Forbes and Hanley in Britain do not hold here. Mr. P. P. Car- penter when in Montreal very kindly went over my collections with me, and expressed himself satisfied that we have the forms recognised in Britain as elliptica, sulcata, and compressa^ what- ever their specific value. My impression at present is that com,' jpressa is a good species, but that sulcata and elliptica as we have them may be varieties of one. It is curious that while A. Lau- rentiana prevails exclusively in the St. Lawrence deposits, the modern species is found at Labrador ; and very possibly, especially when we regard the more inland position and greater elevation of the former, this indicates a difference of age in the deposits. The clay attached to and in the interior of Capt. Orlebar's spe- cimens is very rich in the minute Foraminifera. It contains specimens of all the forms found in the clays of Montreal and described in my former papers, and in addition the following: Fotnlina ohlonga, Fig. 1. Bulimina pupoideSy Fig. 2. B. auriculata f OrhuUna universa, Textularia variahilis, Fig. 3. Nonionina Lahradorica, N. sp. Fig. 4. Truncatulina lohata Fig. 5. Tertiary Fossils of Canada, Sfc, 191 All of these except one are well known living species, and all except Textularia variahiUs have been found in the Gulf of St. Lawrence. This last statement however could not have been made but for specimens obtained from clay taken up by the sounding lead off the coast of Anticosti, from depths varying from 144 to 313 fathoms, and for which also I am indebted to Capt. Orlebar. In these soundings there also occur Globigerina hulloidesa species world-wide in its distribution, and Nodosaria pyrula, neither of which have as yet been found in the tertiary beds of Canada. AVith these recent shells there is a Cythere like C. angulata of the British seas, and numerous spicules of spon- ges; there are also immense numbers of the round perforated silicious shields of Cosa'/iocZisci apparently the C. lineatus &T\d C. radiatus of Ehrenberg. It is a remarkable and at present unac- countable fact that while in the pleistocene beds there is a great abundance of foraminifera, sporge spicules, and valves of cythere, imbedded in calcareous clays like those of the deep sound- ings of the Gulf, the Coscinodisci and other diatoms are absent or at least have not been recognised. Fig. 1. Fig. 2. Fig. 1. — Rotalina ohlonga. 2. — Bulimina pupoides. 3. — Textularia variabiltis. Fig. 3 Truncaiulina lohata. The last species in the list is a little parasitic foraminiferous shell adhermg to shells, stones, and zoophytes. It abounds in Mr. Bell's and Mr. Richardson's recent collections from Gaspe, and since I observed it in Capt. Orlebar's collection, I have found it also at Montreal. It is the Nautilus stellaris of Fabricius. The Nonionina which I name N, Labradorica^ and which is found both recent and fossil, is a very beautiful species. It is pel fectly equilateral, smooth and remarkably white and lustrous^ It is most readily characterised by the great expansion of the last chamber, which spreads laterally and extends in two lobes on 192 Tertiary Fossils of Canada, Sfc, either side of the earlier whorls. When seen from one side it resembles Rotalina turgida, for which indeed I mistook it at first ; but when viewed in front it is seen to be equilateral and to have the characteristic septal aperture of Nonionina. It is about ^qual in size to iV. umhilicatula, and has the last chamber inflated even in young shells. Fig. 4. Fig. 5. Fig. 4. — Nonionina Labradorica, N. sp. 5. — Truncatulina lobata. The Foraminifera from the deeper parts of the Gulf are usually of small size, and this applies also to those from the pleistocene of Labrador. In the past summer another deposit of pleistocene shells was discovered by Sir W. E. Logan at the Mingan Islands, Labrador. The specimens obtained from it consist of 3Iya arenaria and Tellina proxima in hard sand, and have the aspect of a littoral deposit corresponding to the " saxicava sand" of the vicinity of Montreal. 2. Portland, Maine. In last August I enjoyed some opportunities of examining the tertiary deposits at and near Portland, and also at Pond Cove, Cape Elizabeth, where a small patch of this deposit occurs nearly at the level of the sea. At the south end of the city of Portland, in a deep railway cutting, the tertiary beds are well seen, and consist, in ascending order, of boulder clay, fossiliferous stratified clay and sand, and stratified sand and gravel. These beds appear to be very irregular, being entangled in ledges of metamorphic rock, which sometimes rise through them. The distinction between the deeper water and shallow water parts of the deposits is in Tertiary Fossils of Canada, ^c, 193 consequence less strongly marked than at Montreal, but is indi- cated by beds containing Mytilus edulis alone, overlying those which contain shells characteristic of the open sea. At Cape Elizabeth the pleistocene clays occupy depressions between ridges of slate. At the only place where I observed fossils, the deposit is a hard gray stony clay containing a mixture of deep sea and littoral shells. The bivalves are mostly in detached valves and often on edge, as if the bed had been subjected to the pressure of ice after its deposition. The fossils observed in the above mentioned beds are as fol- lows, — those common to Portland and the St. Lawrence valley being marked with asterisks : Balanus crenatus,^ Fusus decemcostatus, (var. horealis,) Buccinum undatum^^ Fusus scalar i/or mis J Natica clausa,^ Mytilus edulisj^ Mactra ovalisj JSaxicava rugosa^ Astarte elliptica, A, corwpressa^ As arctica, Tellina proxima^'^ Fecten Islandicus,^ Mya truncata^ Nucula Jacksoni, Aphrodite Groenlandicay Lepralia variolosa^ L.

It is curious that in the collections of the Canadian Geological Survey, the group of shells obtained by Mr. Bell and Mr. Richardson in dredging on the north coast of Gaspe in about 60 fathoms, is almost precisely that of these Portland beds. On comparison with the St. Lawrence teitiaries, it will be seen that 8 out of 19 species are distinct. It is further to be observed that Fusus decemcostatus replaces the closely sWied F. tor natus. that Saxicava rugosa is much less abundant, that modern Astartes appear instead of A. Laurentiana, and that Mytitus edulis isof large size and of the ordinary form. These differences are however probably nothing more than the effects of the more oceanic position of the Portland beds, as compared with the old inland sea of the St. Lawrence valley, and it will be observed that in respect to the Astartes the Portland beds correspond with those of Labrador. The less elevation of the Portland beds however renders it probable that they are somewhat newer than those of the St. Lawrence valley and of Lake Champlain. In the cabinet of Dr. Jackson of Boston, I had an opportunity of examining a collection of about 14 species obtained by him from the beds on the Pressumpset River, described many years ago by Professor Hitchcock and Dr. Jackson. In this collection while several of the shells found at Portland are absent, I found Leda Portlandica, ^ Nucula proxima, Terehratula septentrionalis^ My a arenaria, and the carapace of a crab. 3. OCCURRENCE OF FRESH WATER SHELLS IN THE PLEIS- TOCENE BEDS. I owe to the kindness of A. Dickson, Esq., additional collections of the fresh water shells and the sands containing them from Paken- ham,f together with a communication from a gentlemen of that place giving a section of the deposits as seen in a deep road cutting. The arrangement is as follows in descending order : Sand and surface soil, about, 10 feet Clay, 10 « * Dr. Gould informs me that he is now satisfied of the correctness of the identification of this shell by Mr. Wood with the species L. truncata of the British Pleistocene and of the artic seas, where it has been found living. t See my paper, Canadian Naturalist, Vol. IV.

Mr. Dickson informs me that a similar case occurs near Clar- enceville, about four miles from the United States frontier, and at an elevation of about ten feet above Lake Charaplain. Speci- mens from this place contain large shells of Unio rectus and U. venfricosus, the latter with the valves cohering, and a Lymnea. Intimately mixed with these in sandy clay are valves of Tellina Groenlandica and 3fya arenaria. I record these facts, without pledging myself to the conclusion that these deposits really mark the margins or river estuaries of the old Pleistocene sea of Canada ; though they will certainly bear that interpretation. In farther connection with these facts, and in relation also to the question why marine fossils have not been found west of Kingston, Mr. Dickson informs me that fossil capelin are found on the Chaudiere Lake, 183 feet above Lake St. Peters, on the Madawaska 206 feet, and at Fort Colonge Lake 365 feet above the same level, a very interesting indication of the gradual recession of the capelin spawning grounds, from this last high elevation to the level of the more celebrated locality of these fossils at Green's Creek. Farther, throughout the Counties of Renfrew, Lanark, Carlton and Leeds, the marine deposits rise to an ele- vation of 425 feet, or nearly the same with that which they reach on Montreal Mountain ; but while this elevation would with the present levels of the country carry a deep sea to the head of Lake Ontario, no marine fossils appear to have been found on the banks of that lake. Was the depression of the later pleistocene period limited to the country east of Lake Ontario, or have the marine deposits of the upper St. Lawrence hitherto escap??d observation 196 Tertiary Fossils of Canada, ^c. or been removed by denuding agencies. The question awaits further explorations for a satisfactory answer. In the mean time it is certain that the boulder clay and deposits corresponding in arrangement and mechanical character to the Leda clay and Saxicava sand of the Lower St. Lawrence exist in these more western regions, though they have not been found to contain marine fossils. 4. CLIMATE OF CANADA IN THE PLEISTOCENE PERIOD. The climate of this period and the causes of its difference from that which now obtains in the northern hemisphere, have been fertile subjects of discussions and controversies, which I have no wish here to re-open. I merely propose to state in a manner level to the comprehension of the ordinary reader, the facts of the case in so far as relates to Canada, and an important infe- ence to which they appear to me to lead, and which if sustained vvill very much simplify our views of this question. Every one knows that the means and extremes of annual tem- perature differ much on the opposite sides of the Atlantic. The isothermal line of 40° for example passes from the south side of the gulf of St. Lawrence, skirts Iceland and reaches Europe near Drontheim in Norway. This fact, apparent as the result of obser- vations on the temperature of the land, is equally evidenced by the inhabitants and physical phenomena of the sea. A large pro- portion of the shell fish inhabiting the gulf of St. Lawrence and the coast thence to Cape Cod, occur on both sides of the Atlantic, but not in the same latitudes. The marine fauna of Cape Cod is parallel in its prevalence of boreal forms with that of the south of Norway. In like manner the descent of icebergs from the north, the freezing of bays and estuaries, the drifting and pushing of stones and boulders by ice, are witnessed on the American coast in a manner not parallelled in corresponding latitudes in Europe. It follows from this that a collection of shells from any given latitude on the coasts of Europe or America, would bear testimony to the existing difference of climate. The geologist appeals to the same kind of evidence with reference to the climate of the later tertiary period, and let us enquire what is its testimony. The first and most general answer usually given, is that the pleistocene climate was colder than the modern. The proof of this in Western Europe is very strong. The marine fossils of this Tertiary Fossils of Canada, Sfc, 197 period in Britain are more like the existing fauna of Norway or of Labrador tlian the present fauna of Britain. Great evidences exist of driftage of boulders by ice, and traces of glaciers on the higher hills. In North America the proofs of a rigorous climate and especially of the transport of boulders and other materials by ice are equally good, and the marine fauna all over Canada and New England is of boreal type. In evidence of these facts I may appeal to the papers and other publications of Sir C. LyeU and Professor Ramsay on the formations of the so called glacial period in Europe and America,* and to my own previous papers on the tertiaries of Canada. Admitting however that a rigorous climate prevailed in the pleistocene period, it by no means follows that the change has been equally great in different localities. On the contrary while a great and marked revolution has occurred in Europe, the evi- dences of such change are very much more slight in America. In short, the causes of the coldness of the pleistocene seas to some extent still remain in America, while they must have dis- appeared or been modified in Europe. If we enquire as io these causes as at present existing, we find them in the distribution of ocean currents, and especially ;n the great warm current of the gulf stream, thrown across from Ame- rica to Europe, and in the Arctic currents bathing the coasts of America. In connection with these we have the prevailing wes- terly winds of the temperate zone, and the great extent of land and shallow seas in Northern America. Some of these causes are absolutely constant. Of this kind is the distribution of the winds depending on the earth's temperature and rotation. The courses of the currents are also constant, except in so iar as modified by coasts and banks; and the direction of the drift-scratches and transport of boulders in the pleistocene both of Europe and Ame- rica, show that the arctic currents at least have remained un- changed. But the distribution of land and water is a variable element, since we know that in the period in question nearly all northern Europe, Asia and America were at one time or another under the waters of the sea, and it is consequently to this cause that we must mainly look for the changes which have occurred. * Lyell's travels in North America, Ramsay on tlie glaciers of Wales, and on the glacial phenomena of Canada. See also Forbes on the fauna and flora in the British Islands, in Memoirs of geological surrey. 198 Tertiary Fossils of Ca?iadaf ^c. Siicli changes of level must, as has been long since shown by Sir Charles Lyell, modify and change climate. Every diminu» tion of the land in arctic America must tend to render its climate less severe. Every diminution of land in the temperate regions must tend to reduce the mean temperature. Every diminution of land any where must tend to diminish the extremes of annual temperature ; and the condition of the southern hemisphere at pre- sent shows that the disappearance of the great continental masses under the water would lower the mean temperature but render the climate much less extreme. Glaciers might then exist in latitudes where now the summer heat would suffice to melt them? as Darwin has shown that in South America glaciers extend to the sea level in latitude 46° 50' ; and at the same time the ice would melt more slowly and be drifted farther to the southward. Any change that tended to divert the arctic currents from our coasts would raise the temperature of their waters. Any change that would allow the equatorial current to pursue its course through to the Pacific or along the great inland valley of North America, would reduce the British seas to a boreal condition. The boulder formation and its overlying fossiliferoiis beds prove, as I have in a previous paper endeavoured to explain with regard to Canada, and as has been shown by other geologists in the case of other regions, that the land of the northern hem- isphere underwent in the later tertiary period a great and gra- dual depression and then an equally gradual elevation. Every step of this process would bring its modifications of climate, and when the depression had attained its maximum there probably was as little land in the temperate regions of the northern hemis- phere as in the southern now. This would give a low mean tem- perature and an extension to the south of glaciers, more espe- cially if at the same time a considerable arctic continent remained above the waters, as seems to be indicated by the effects of ex- treme marine glacial action on the rocks under the boulder clay* These conditions, tactually indicated by the phenomena them- selves, appear quite sufficient to account for the coldness of the seas of the period, and the wide diffusion of the gulf stream caus- ed by the subsidence of American land, or its entire diversion into the Pacific basin*, would give that assimilation of the American * This is often excluded fi-om consideration, owing to the fact that the marine fauna of the gulf of Mexico differs almost entirely from that of the Pacific coast ; but the question still remains whether this diffe- rence existed in the later tertiary period, or has been established in the modern epoch, as a consequence of changed physical conditions. Tertiary Fossils of Canada, ^c. 199 and European climates so characteristic of the time. The climate of western Europe in short, would under such a state of things be greatly reduced in mean temperature, the climate of America would suflfer a less reduction of its mean temperature, but would be much less extreme than at present ; the general effect being the establishment of a more equable but lower temperature throughout the northern hemisphere. It is perhaps necessary to add that the existence on the land, during this period of depres- sion, of large elephantine mammals in northern latitudes, as for instance the Mammoth and Mastodon, does not contradict this con- clusion. We know that these creatures were clothed in a manner to fit them for a cool climate, and an equable rather than a high tem- perature was probably most conducive to their welfare, while the more extreme climate consequent on the present elevation and dis- tribution of the land may have led to their extinction. The establishment of the present distribution of land and water, giving to America its extreme climate, leaving its seas cool and throwing on the coasts of Europe the heated water of the tropics, would thus affect but slightly the marine life of the American coast, but very materially that of Europe, producing the result so often referred to in these papers, that our Canadian Pleistocene fauna differs comparatively little from that now existing in the gulf of St. Lawrence, though in so far as any difference subsists it is in the direction of an arctic character. The changes that have occurred are perhaps all the less that so soon as the Lau- rentide hills to the north of the St. Lawrence valley emerged from the sea, the coasts to the south of these hills would be effectually protected from the heavy northern ice drifts and from the arctic currents, and would have the banefit of the full action of the summer heat, advantages which must have existed to a less extent in western Europe. It is farther to be observed that such subsidence and elevation would necessarily afford great facilities for the migration of arctic marine animals, and that the difference between the modern and newer pliocene faunas must be greatest in those localities to which the animals of temperate regions could most readily migrate after the change of temperature had occurred. It has been fully shown by many previous writers on this sub- ject, that the causes above referred to are sufficient to account for all the local and minor phenomena of the stratified and unstra 200 STietch of the Life of Mr, David Douglas, tified drifts, and for the driftage of boulders and other materials, and the erosion that accompanied its deposition. Into these subjects I do not propose to enter; my object in these remarks being merely to give the reasons for my belief stated in previous papers on this subject, that the differencG of climate between pleistocene and modern Canada, and the less amount of that diffe- rence relatively to that which has occurred in western Europe, may be explained by a consideration of the changes of level which the structure and distribution of the boulder clay and the over- lying fossihferous beds prove to have occurred. ARTICLE 'X.Yl.— Abridged Sketch of the life of Mr. David Douglas J Botanist ^ with a few details of his travels and discoveries, {Continued from last Number.') Turning with the boats as far back as Wallawalla, Douglas proceeded on horseback to the Fourches de I'Eau claire, up the south branch of the Columbia about 150 miles. The party which he accompanied thither came this length for the purpose of trading horses, but getting into difficulties with the Shohoptins, or Nez-perces Indians, and Mr. Douglas finding that little new could be obtained in that quarter, his steps were bent right north to Spokan House, where he was again kindly welcomed by the old hunter Jacquo Finlay. After parting with Jacquo, in crossing the Cedar river lying between Spokan and the Columbia, his horse stuck in the mud, and in the struggle to get extricated the rider was struck a sharp blow that threw him headlong into the water. This misfortune cost him his knapsack, which contained all the seeds he had collected, and his note-book, which were lost in the stream. In this trim he pursued his route, reaching Fort Colvile on the 5th of August, where he found Mr. John Dease in charge. An account of a fray between the natives, viz, the Kettle Falls Indians, and a portion of the Cootanies Tribe, who had come to this quarter for the purpose of fishing, is thus given by Douglas. — " The parties met to day stark naked, at our camp, painted " some red, some black, others white and yellow, all with their bows Sketch of the Life of Mr. David Doiiglas. 201 " strung, while those who had guns and ammunition, brought their " weapons charged and cocked. War caps, made of the Calumet '' Eagle's feathers, were the only particle of clothing they had on. " Just as one of these savages was discharging an arrow from his " bow, aimed at a chief of the other party, Mr. Dease hit him " such a blow on the nose as stunned him, aad the arrow fortunately " only grazed the skin of his adversary, passing along the rib op- "■ posite to his heart, without doing him much injury. The '' whole day was spent in clamour and haranguing, and unable to " foresee what the issue might be, we were prepared for the worst. " Mr. Dease, however, succeeded in persuading them to make " arrangements for peace, and begged this might be done without " delay on the morrow, representing to them how little they had ^' ever gained by their former wars, in which they had mutually '' butchered one another like dogs. Unluckily for me, my guide, " the Wolfe, is equally wanted by his party, whether to make war " or peace, therefore, I am obliged to wait for him. On the 19th he bade adieu to Mr. Dease, taking horse to Okawyan, where he procured a guide and small canoe. Soon after embarking, in descending a rapid, he took the precaution of walking along shore, carrying with him his papers, plants, seeds, and blanket. While thus occupied, the canoe in descending was struck by a surge in the rapid, and emptied of all its contents ex- cept a little dried meat which had been fixed in hard, in the nar- row part of the bow. Deprived thus of cooking utensils, or any of the slightest comfort or convenience in the shape of travelling- appointment, he pursued his course to Wallawalla, where finding a fresh guide, he continued onward and, after some trouble, as well as assistance from Indians, landed on the first day of August on the Beach above Fort Vancouver. This journey is thus closed very expressively in his own words. — " In poor plight, weary and travel-soiled, glad at heart, though " possessing nothing but a shirt, leather trousers, and old hat, hav- " ing lost my jacket and neck-kerchief, and worn out my shoes, I " made my way to the fort, having traversed eight hundred miles " of the Columbia valley in twelve days, unattended by a single " person except my Indian guides." His collections were now shipped for England, consisting of a great mass of dried specimens of plants besides Zoological subjects. The seeds which he had forwarded these two first years on the 202 SJcetch of the Life of Mr. David Douglas. Columbia, to the Horticultural Society, were the means of intro- ducing to the knowledge of gardeners above 160 new flowers and plants, all interesting, many of utility, others of uncommon splen- dor and beauty. Among these were 14 species of currant, 5 of Raspberry and 2 of Berterry, while the flower garden bloomed with 2 new species of Brodicea, 2 of CalocJiortiis, 3 of Caprifo- lium, 3 of ClarJda, 2 of CUntonia, 5 of CoUonia, 3 of Collin- sia, 3 of Eutoca, 5 GiUas, 24 Lupines, 5 of 3Iinculus, 10 of (EnotJiera, 13 of Penstemon, 6 of Potentilla, and 3 of Spirea, besides many single species of other genera — altogether an acces- sion to the shrubbery and flower-garden which must ever be highly appreciated. On the 15th of September Mr. Douglas accom- panied a trapping party to the southward or the Umptqua coun- try, with the view principally of procuring cones and seeds of the large pines there growing in the greatest perfectioUc At this time the Umptqua river was but little known, and only occasionally visit- ed by interpreters or clerks of the Fur trade, for the purpose of bar- tering with the natives. The mode of travelling suited the bo- tanist well. He had time to look about him, and gather much in the Willamette valley. A month elapsed, but on the 16th of October he arrived on the heights overlooking the Umptqua, the last days having been occupied in passing amongst timber of enormous growth and through thickly wooded forests where the path was frequently obstructed by fallen trees, measuring from 200 to 250 feet in length. Here first commences the district of the Califor- nian laurel, the Oreodapnue Calif ornica, which perfumes the air in every direction with its odours. Our Adventurer did not reach the wished for groves of Pinus Lamhertiana without risk and danger. Having obtained a guide in the person of a youth who had been brought from the southward as a slave, he started from the trapping camp on the 18th, next day, however, having fallen into a gully in pursuit of a wounded deer, he was so much stunned and hurt as to be obliged to return to camp. Whence he again sallies on the 23rd, in pursuit of the great Pine. Proceed- ing due south, we find him on the 25th of the month not far from the object of his search, but very disagreeably lodged as his journal thus shows. — '' Wednesday the 25th. Last night was one of the most dread- '' ful I ever witnessed ; the rain falling in torrents, was accom- " panied by so much wind as made it impossible to keep in a fire ; SJcetch of the Life of Mr, David Douglas, 203 " and to add to my miseries the tent was blown down about my '' ears, so that I lay till daylight, rolled in my wet blanket on *' Pteris aqidlina, with the drenched tent piled above me. Sleep " was of course not to be procured ; every few minutes the falling *' trees came down with a crash which seemed as if the earth " was cleaving asunder, while the peals of thunder and vivid " flashes of forky lightening produced such a sensation of terror " as had never filled my mind before, for I had at no time exper- " ienced a storm under similar circumstances of lonliness and un- " protectedness of situation. Even my poor horses were unable to " endure it without craving, as it were, protection from their master '' which they did by cowering close to my side, hanging their heads ^' upon me and neighing. Towards daylight the storm abated, " and before sunrise the weather was clear, though very cold. I " could not stir without making a fire, and drying some of my " clothes, every thing being soaked through ; and I indulged " myself with a pipe of tobacco, which was all I could afibrd. " At ten o'clock I started, still shivering with cold, though I had " rubbed myself so hard with a handkerchief that I could no " longer endure the pain. Shortly after I was seized with intense " headache, pain in the stomach, giddiness and dimness of sight. " All the medicine I had being reduced to a few grains of calomel, '' I felt un wiling, without absolute necessity, to take to this last " resource, and therefore threw myself into a violent perspiration " by strong exercise, and felt somewhat relieved towards evening, " before which time I arrived at three lodges of Indians, who " gave me some fish,. The food was such as I could hardly have " eaten if my destitution were less. Still I was thankful for it, " especially as the poor people had nothing else to ofier me ; the " night being dry, I camped early in order to dry the remaining " part of my clothing." " Thursday the 25th. Weather dull, cold, and cloudy. When " my friends in England are made acquainted with my travels, I " fear they will think that I have told them nothing, but my " miseries, This may be true, but I now know as they may do •• also, if they choose to come here on such an expedition, " that the objects of which I am in quest, cannot be obtained " without labour and anxiety of mind, and no small risk of " personal safety, of which latter statement my this day's adven- " tures are an instance. I quitted my camp early in the morning 204 Sketch of the Life of Mr. David Douglas* " to survey the neighbouring country, leaving my guide to take " charge of the horses until my return in the evening, when I " found that he had done as I wished, and in the interval dried " some wet paper which I had desired him to put in order. " About an hour's walk from my camp, I met an Indian, who on " perceiving me instantly strung his bow, placed on his left arm a " sleeve of Racoon skin, and stood on the defensive. Being quite " satisfied that this conduct was prompted by fear, and not by '' hostile intentions^ the poor fellow having probably never seen " such a being as myself before, I laid my gun at my feet, on the '' ground and waved my hand for him to come to me, which he " did slowly and with great caution. I then made him place his " bow and quiver beside my gun, and striking a light gave him a " smoke out of my own pipe, and a present of a few beads. " With my pencil I made a rough sketch of the cone and pine " tree which I wanted to obtain, and drew his attention to it? " when he instantly pointed with his hand to the hills fifteen or " twenty miles distant, towards the south ; and when I expressed " my intention of going thither, cheerfully set about accompany- " ing me. At midnight I reached my long-wished-for pines, and " lost no time in examining them, and in endeavoring to collect " specimens and seeds. New and strange things seldom fail to " make strong impressions and are therefore, frequently over-rated ; " so that lest I should never again see my friends in England to '' inform them verbally of this most beautiful and immensely " grand tree, I shall here state the dimensions of the largest I " could find among several that had been blown down by the '' wind. At three feet from the ground its circumference is 57 ft* " 9 inches ; at 134 ft,, 17 ft. 5 inches ; the extreme length 245 ft. " The trunks are uncommonly straight, and the bark, remarkably " smooth for such large timber, of a whitish or light brown colour, " and yielding a great quantity of bright amber gum. The tallest " stems are generally unbranched for two thirds of the height " of the tree ; the branches rather pendulous with cones '' hanging from their points like sugar loaves in a grocer's '^ shop. These cones, are however, only seen on the loftiest trees, " and the putting myself in possession of three of these, (all I " could obtain) nearly brought my life to a close. As it was im- " posible either to climb the tree or hew it down, I endeavoured " to knock of the cones by firing at them with ball, when the re- Sketch of the Life of Mr, David Douglas, 205' " port of my gun brought eight Indians, all of them painted with " red earth, armed with bows, arrows, bone tipped spears and flint '^ knives. They appeared anything but friendly. I endeavoured " to explain to them what I wanted, and they seemed satisfied " and sat down to smoke, but presently I perceived one of them " string his bow, and another sharpen his flint knife with a pair of " wooden pincers, and suspend it on the wrist of the right hand. " Further testimony of their intentions was unnecessary. To save '' myself by flight was impossible, so without hesitation I stepped *' back about five paces, cocked my gun drew one of the pistols '' out of my belt, and holding it in my left hand, and the gun in " my right, showed myself determined to fight for my life. As " much as possible, I endeavoured to preserve my coolness, and " thus we stood looking at one another, without making any move- " ment or uttering a word, for, perhaps, ten minutes, when one, " at last, who seemed the leader, gave a sign that they wished " for some tobacco : this I signified that they should have, if they '' fetched me a quantity of cones. They went off immediately " in search of them, and no sooner were they all out of sight, than '' I picked up my three cones and some twigs of the trees, and " made the quickest posssible retreat, hurrying back to my camp, ^' which I reached before dusk, the Indian who last undertook to " be my guide to the trees I sent off before gaining my encamp- " ment, lest he should betray me. How irksome is the darkness " of night to one under my present circumstances ! I cannot " speak a word to my guide, nor have I a book to divert my " thoughts, which are continually occupied with the dread lest the " hostile Indians should trace me hither and make an attack ; I " now write lying on the grass, with my gun cocked beside me, " and penning these lines by the light of a Columbian candle, *' namely, an ignited piece of rosiny wood. — To return to the " tree which nearly cost me so dear, the wood is remarkably fine " grained and heavy ; the leaves short and bright green, inserted " five together, in a very short sheath ; of my three cones, one " measured fourteen inches and a half, and the two others are " respectively half an inch and an inch shorter, all full of fine '' seed. A little before this time of year, the Indians gather the '' cones and roast them on the embers, then quarter] them and ' shake out the seeds, which are afterwards thoroughly dried and pounded into a sort of flour, or else eaten whole. 206 Sketch of the Life of Mr. David Douglas, " Friday the 27tli. My last guide went out at midnight in " search of trout, and brought me home a small one, which served " for breakfast. Two hours before daylight he rushed in with " great marks of terror uttering a shriek which made me spring " to my feet, as I concluded that my enemies of yesterday had " tracked out my retreat. • He, however, gave me to understand, " by gesture that he had been attacked by a grizly bear. I " signed to him to wait till daylight, when I would go out and " look for, and perhaps, kill the creature. A little before sunrise, " Bruin had the boldness to pay us a visit, accompanied by two " cubs, one of last year's brood, and one of this ; but as I could '' not consistently with safety receive these guests before daylight, " I had all my articles deposited in the saddle-bags, and driven " upon one horse to a mile distant from the camp, when I returned " mounted upon the animal, Mr. McLoughlin had given me, and " which stands fire remarkably well, and found the bear and her " two young ones feeding on acorns under the shade of a large oak. " I allowed the horse to walk within twenty yards, when all three " stood up and growled at me. I levelled my gun at the heart of " the old one, but as she was protecting her young by keeping " them right under her, the shot entered the palate of one of " these, coming out at the back of the head, when it instantly fell. " A second shot hit the mother on the chest as she stood up with *' the remaining cub under her belly, on which abandoning it, she " fled to an adjoining hummock of wood. The wound must have " been mortal, as these animals never leave their cubs until they '' themselves are on the point of sinking. With the carcase of " the young bear I paid my last guide, who seemed highly to prize " the reward, and then abandoned the chase, deeming it only pru- " dent, after what happened yesterday, to retrace my steps towards " the camp of my friends. So I returned crossing the river two " miles lower down than formerly, and halted at night in a low " point of wood near a small stream. " Saturday and Sunday, the 28th, and 29th. Both these days " being very rainy, as the day before also was, and having very " little clothing, I made all the exertion in my power to reach " Mr. McLeod's encampment near the sea. It was impossible to " keep myself dry, and the poor horses were so fatigued that I " was obliged to walk all the way and lead my own by the bridle, " the road becoming continually worse and worse from the floods Sketch of the Life of Mr. David Douglas, 207 " of rain. On Saturday niglit I halted at my second crossing " place, but could procure no food from the Indians, the bad " weather having so swollen the rivers, as to prevent their fishing, " I boiled the last of my rice for supper, which gave but a scanty " meal, and resuming my march, the next day, proceeded pretty ^' well till, reaching the wooded top of the lofty river bank, my '•' jaded horse stumbled and rolling down, descended the whole '' depth over dead wood, and large stones, and would infal- " libly have been dashed to pieces in the river below, had he not " been arrested by getting himself wedged fast between two large " trees that were lying across one another near the bottom. I '' hurried down after him, and tying his legs and head close down " to prevent his struggling, cut with my hatchet through one of " the trees, and set the poor beast at liberty. I felt a great deal " on this occasion, as the horse had been Mr McLoughlin'spres- " ent to me, and was his own favourite animal. Reached the camp '' at dusk, where I found only Michel La Framboise, our Chenook " interpreter, and an Indian boy, who told me that the savages " had been very troublesome ever since our brigade of hunters " left him some days before. The former kindly assisted me " to pitch my tent, and gave me some weak spirits and water, with " a basin of tea, made from a little that he had brought from Fort " Vancouver, and which greatly refreshed me." Soon after this, messengers having to be dispatched to Fort Van- couver, Mr. Douglas took advantage of the opportunity and ac- companied them homewards. After twelve days travelling under the disadvantage of hunger cold and rain, he reached Fort Vancou- ver, on the 20th of November, although, not without losing the greater part of his collection in crossing the river Sandiam, a tributary of the Willamette, then swollen with rain. Fortu- nately, with other rarities, the pine cones were saved. It was at this period I had the pleasure of making the acquain- tance of Mr. Douglas. Having crossed the Columbia, I arrived in this month of November at head quarters, and soon found the man of science to be one of the heartiest, happiest mortals in our little society. He now received letters from England, consolotary to him in every respect, and the sense of inward satisfaction, as well as the bright gleams cast on his spirit, by the cheering words of those he loved and respected in his native country, brought out in full glow the warm effusions of a pure and honest heart. 208 STcctch of the Life of Mr. David Douglas. The Spring of 1827 was severe, and mucli snow had fallen. The consequence was that many horses died at Fort Vancouver, and we were visited by the various species of beasts and birds of prey that abound in that country. Most conspicuous among these were the California vulture. This magnate of the air was ever hovering around, wheeling in successive circles for a time, then changing the wing as if wishing to describe the figure 8 ; the ends of the pinions, when near enough to be seen, having a bend waving upwards, all his move- ments, whether of soaring or floating ascending or descending, were lines of beauty. In flight he is the most majestic bird I have seen. One morning a large specimen was brought into our square, and we had all a hearty laugh at the eagerness with which the Bo- tanist pounced upon it. In a very short time he had it almost in his embraces fathoming its stretch of wings, which not being able to compass, a measure was brought, and he found it full nine fee* from tip to tip. This satisfied him, and the bird was carefully transferred to his studio for the purpose of being stufi"ed. In all that pertained to nature and science he was a perfect enthusiast. It has been frequently matter of surprise how quickly these birds collect when a large animal dies. None may be seen in any direction, but in a few minutes after a horse or other large animal gives up the ghost they may be descried like specks in the aether, nearing by circles to the prey, when as yet one would not suppose the effluvia from the carcase had reached above a hundred yards. This renders it probable that their sight as well as sense of smell- ing is very acute, bnt that the latter can guide them entirely with- out aid from the other, I am certain, as I have started them from carrion within the edge of a forest under bushes which must have precluded the possibility of their seeing the carcase before they alighted on it. March of 1827 arrived, and we were obliged to part with our agreeable companion. On the 20th of that month he left us to proceed to England by traversing the Rocky mountains in Lat. 54o in company with the Hudson's Bay party, which was accustomed to cross annually to York factory with Spring despatches. (jTo he Continued,^ Reviews and Notices of BooJcs, 209 REVIEWS AND NOTICES OF BOOKS. The Life, Travels, and Books of Alexander von Humboldt. "With an in- troduction by Bayard Taylor. New York, Rudd & Carleton ; Montreal, B. Dawson & Son, pp. 482. This is a very able and interesting account of the life and labours of Humboldt. The author's signature is R. H. S., why the full name is concealed, we cannot tell. The task undertaken by him or her, is ably executed. Those who wish to know what Humboldt did, and the foundation upon which his great fame rests, will find the information desired in this volume. It does not profess to be a biography of the great naturalist and philos- opher, but it is a sketch taken from the most authentic sources of the course of his life, from the cradle to the grave. It tells us how and where his youth was spent, at what universities he stud- ied, who were his teachers, what his favorite pursuits, his early employments and thirst for foreign travel. A brief notice is given of his travels and researches, in company with the botanist Bonpland, in the regions of South America, during the early part of the nineteenth century. It traces the course of Humboldt's travels through Russia to the Ural Mountains, and through northern Asia to the mines of the Altai. Finally, the author gives a brief account of the character and cost of the great works prepared and edited by Humboldt ; and concludes with agreeable notices of his last days. The name of Humboldt has become a household word in Europe and America. He is everywhere known and acknowledged to be the prince of Modern Science. For those who have not much leisure to peruse the works and to make themselves familiar with the scientific researches of the late Baron von Hu;nboldt, we would recommend the perusal of this volume. It is agreeably written, and is worthy of a place in the study or the family library. A. f. k. A first lesson in Natural History. By Actcea. (Mrs. Agassiz.) Boston, Little, Brown, & Co. Montreal, B.

Nat. 4 Vol. V. 210 Reviews and Notices of Boohs. children. Its aim is to make them acquainted with some of the curious aud wonderful forms of animal life which are to be found on the sea shore. Having been revised by Agassiz himself, there is the best guarantee that its facts may be im^^licitly relied upon. Children may, therefore, be assured that strange as these stories are, they are all perfectly true. The four chapters into which the book is divided treat in succession most pleasantly of sea-Anem- ones and Corals ; Coral Keefs ; Hydroids and Jelly-fishes ; Star- fishes and Sea Urchins. They are addressed in the form of stories to two children, and are so plain aud clear, and yet elegant in their language, that they may easily be understood and appre- ciated by very young persons. "We are sure that this will be a favourite childrens book. Although intended for the young, it may yet be read with profit by fathers and mothers. It is beau- tifully printed and the illustrations are good. We trust that the authoress may be induced to continue these stories, as they seem to us well-fitted to turn the attention of the young from frivolous and hurtful tales to the healthy and delightful pursuit of Natural Science. a. f. k. A Manual of Scientific and Practical Agriculture for the School and the Farm. By J. L. Campbell, A.M., Professor of Phys. Science, Washington College, Va., with numerous illustratiors. pp. 442. Philadelphia, Lindsay & Blakiston. Montreal, B. Dawson & Son. This book has been written to supply the rapidly increasing demand for scientific information applicable to the daily business of agriculture. The chief purpose kept in view in its several chapters has been the preparation of a Manual which might serve as a guide to the young in the acquisition of the sciences per- tainining to agriculture. None of the systematic books hitherto published on this subject were adapted to the necessities of the Southern and Western States of America. This unoccupied place the present publication is intended to fill. The plan is both sim- ple and complete. It embraces in well digested and clearly expressed paragraphs all the subjects which pertain to the science of farming. The first chapter contains definitions and illustrations of terms, and the twenty-five following embrace the leading facts and principles of chemistry, geology, vegetable physiology, prac- tical treatment of all kinds of soils, and the various cereals, root^ Reviews and Notices of Booh. 211 and plants, with which farming on this continent is conversant. The history and property of manures, and the application of fer- tilizers is carefully treated. The planting and culture of com, wheat, oats, potatoes, hay, beans and peas, tobacco and cotton, are the topics of successive chaptors. And finally root-crops, to- gether with the leading facts of animal physiology, and the selection and care of stock, receive careful attention. The Ap- pendix contains a list of chemicals and apparatus, with tables of money and weights and measures. The wood-cut illustrations are worthy of all praise. The style is highly finished, clear, and forcible. We regard this book as one of a high order of excel- elnce, and which might wnth advantage be in the hands of the young farmers of Canada. a. f. k. The British Tortrices. By S. J. Wilkinson. (Van Voorst.) — The great barrier to an exhaustive study of the animals of the British Islands is its insects. Hence we find naturalists who are tolerably conversant with our Vertebrate animals, our MoUusca and Radiata, who scarcely know a single insect. On the other hand, the naturalist who ventures on the insect kingdom is irre- deemably committed to its study. A lifetime is quite insufficient to get through its various groups. He begins with the beetles, and there he sticks : he does not even become an entomologist ; he is the student of a group, and is dubbed a coleopterist. Thus we have works devoted to his use, and a ' Coleopterist's Manual ' to guide him in his studies. If betakes up butterflies and moths, the same affluence obstructs his progress. He becomes a lepidop- terist, or a micro -lepidopterist; and only by this exclusive atten- tion to a branch can he expect to aid in the development of the science of Entomology. The same is true of the other great groups of insects, of Diptera, Hymenoptera, Neuroptera, and the rest. Thus it is that the reputation of men who have spent a lifetime in the study of animal habits and forms, and made for themselves an undying fame, is scarcely known to the public at all. The amount of accurate observation, logical generalization, and scientific thought, expended on insects alone, is probably as great as that in all other departments of Zoology. Although its practical value may be thought less, it is, nevertheless, in this group of animals that some of the great laws of animal morpho- 212 Reviews and Notices of BooJcs, logy have been most successfull}'^ worked out, whilst the hosts of those little creatures that dwell in our forests, live in our fields become the pests of our houses, our beds, and our food, give a practical value to the knowledge of their habits, which cfinnot be claimed by animals of greater size, and which are more easily observed. The work before us is an illustration of the generally unappreciated labours of the entomologist. There is a little group of moths whose caterpillars swarm in our gardens, attack our beans and peas, and twist themselves curious homes in the leaves of our limes, laburnams, and other trees. These are the larvae of the " British Tortrices." Many of them have been figured and named, but no complete work descriptive of them existed, and Mr. Wilkinson has in this volume supplied the want. He has described, with great accuracy, from original specimens, three hundred species of these insects. As this has been done with the skill of a master, the work must take its place beside the great descriptive works devoted to other families of insects. To the reading public such a work presents no attractions. In passing from page to page it looks like a wearisome repetition of nearly the same forms ; but let no one despise who cannot understand, for in these descriptions lies the very soul of zoological science. Without an accurate apprehension of individual forms, there could be no general law of form, and the great science of Morphology would cease to advance. Every now and then, however, amid the dreary waste of description, we get a pleasant peep into the entomologist's way of life. We find his favorite caterpillars feeding on the ferns of Wimbledon Common, the oaks of New Forest, the hawthorns of Epping Forest, the birches of the banks of Dee, or the heather of Scotch mountains. These "habitats" are suggestive of pleasant rambles amongst the forests, rivers and mountains of our island ; and we cannot but feel that such pur- suits must have an invigorating influence on the mind and body, in addition to their importance in contributing to the advance- ment of human knowledge. — Athenceum. The Rudiments of Botany, Structural and Pkysiological. By Christopher Dresser. (Virtue.) — This very modest title intro- duces in many respects one of the most complete works on struc- tural botany in our language. Mr. Dresser is Lecturer on Reviews and Notices of Books?^ 213 BotaFij, and Master of the Botanical Drawing Classes in the Department of Science and Art ol the Privy Council for Educa- tion. In this capacity he has frit the want of more copious illus- trations than ordinary botanical manuals supj)ly. lie has accord- ingly endeavoured to supply this want, and lias produced a work which, f >r completeness and beauty of illustiation, has certainly no rival. The work is more particularly devoted to structure, and the physiological remarks are everywhere only secondary and incidental. It is written in the form of simple propositions easily comprehended by the student, and every detail of the structure of plants is copiously illustrated by oiiginal drawings, or by wood- cuts from works of acknowledged excellence. As the work is written for Art students, it has been evidently the object of the author to divest his illustrations of the mere diaivrammatic form which they assume in most works on botany, and in this, we think, he has to a large extent succeeded. To say that all the drawings are of equal excellence would be doing injustice to those which are executed with gieat tru
