PPATE 1, Is an imaginary Section constructed to express, by the insertion of names, and colours, the relative positions of the most important classes, both of unstratified and stratified rocks, as far as they have yet been ascertained. It is found- ed on many series of accurate observations, on several lines taken across Europe, between the British islands and the Mediterranean Sea. Although no single straight line exhi- bits every formation complete in the full order of succession here represented, no fact is inserted for which authority cannot be found. The near approximation of this synoptic representation to the facts exhibited by an actual section, may be estimated by comparing it with the admirable sec- tion across Europe, published by Mr. Conybeare in the Re- port of the Proceedings of the British Association for the Advancement of Science, 1832, and with his sections of England, in Phillips and Conybeare's Geology of England and Wales. The chief merit of the above Section is due to the Ta- lents of Mr. Thomas Webster; it is founded on a more simple section which has for several years been used by him in his lectures, and which exhibits the relations of the Granitic and Volcanic rocks to the stratified formations, VOL. II.-1 EXPLANATION OF PLATE 1. and to one another, more intelligibly than I have ever seen expressed elsewhere. This original drawing by Mr. Web- ster has formed the basis of the present enlarged and im- proved section, into which many important additions have been introduced by the joint suggestions of Mr. Webster and myself. The selection and arrangement of the animals and plants is my own; they have been drawn and engraved (together with a large proportion of the woodcuts) by Mr. J. Fisher, of St. Clements, Oxford. For facility of reference, I have numbered the principal groups of stratified rocks represented in the section, accord. ing to their most usual order of succession; and I have de- signated by letters the crystalline or unstratified rocks, and the injected masses and dikes, as well as the metallic veins, and lines of fracture, producing dislocations or faults. The crowded condition in which all the Phenomena represented in this section, are set together, does not admit of the use of accurate relative proportions, between the stratified rocks and the intruded masses, veins and dikes by which they are intersected. The adoption of false proportion is, how- ever, unavoidable in these cases, because the veins and dikes would be invisible, unless expressed on a highly exagge- rated scale. The scale of height throughout the whole sec- tion is also infinitely greater than that of breadth. The plants and animals also are figured on no uniform scale. The extent of the different formations represented in this section, taking their average width as they occur in Europe, would occupy a breadth of five or six hundred miles. A scale of heights, at all approaching to this scale of breadth, would render the whole almost invisible. The same cause makes it also impossible to express correctly the effect of valleys of denudation, which are often excavated through strata of one formation into those of another subjacent for- mation EXPLANATION OF PLATE I. 3. As it would encumber the section to express Diluvium, wherever it is present, it is introduced in one place only, which shows its age to be more recent than the newest of the Tertiary strata; it is found also lodged indiscriminately upon the surface of rocks of every formation. Granite. In our early Chapters we have considered the Theory which refers unstratified rocks to an igneous Origin, to be that which is most consistent with all the known Pheno- mena of Geology, and the facts represented in the Section now before us are more consistent with the Postulates of this Hypothesis, than with those of any other that has hitherto been proposed. I have, therefore, felt it indispen- sable to adopt its language, as affording the only terms by which the facts under consideration can be adequately de- scribed. Assuming that Fire and Water have been the two great Agents employed in reducing the surface of the globe to its actual condition, we see, in repeated operations of these agents, causes adequate to the production of those irregular Elevations and Depressions of the fundamental Rocks of the Granitic series, which are delineated in the lower Region of our Section, as forming the basis of the entire Superstructure of stratified Rocks. Near the right extremity of this Section, the undulating surface of the fundamental Granite (a. 5. a. 6. a. 7. a. 8.) is represented as being, for the most part, beneath the level of the Sea. On the left extremity of the Section (a. 1. a. 2. a. 3.) the Granite is elevated into one of those lofty Alpine ridges, which have affected, by their upward movement, the entire series of stratified Rocks. Corresponding formations of Primary and Transition EXPLANATION OF PLATE I. Strata, are represented as occurring on each side of this ele- vated Granite, which is supposed to have broken through, and to have carried up with it to their present elevated and highly inclined position, strata that were once continuous and nearly horizontal.* The general history of Elevation appears to be, that mountain chains of various extent, and various directions, have been formed at irregular intervals, during the deposi- tion of stratified rocks of every age; and that Granite had, in many cases, acquired a state of solidity before the period of its elevation. Within the primary Granite, we find other forms of Gra- nitic matter, (a. 9.) which appear to have been intruded in a state of fusion, not only into fissures of the older Granite, but frequently also into the Primary stratified rocks in con- tact with it, and occasionally into strata of the Transition and Secondary series, (a. 10. a. 11.) these Granitic injec- tions were probably in many cases, contemporaneous with the elevation of the rocks they intersect; they usually as- sume the Condition of Veins, terminating upwards in small branches; and vary in dimensions, from less than an inch, to an indefinite width. The direction of these veins is very irregular: they sometimes traverse the Primary strata at right angles to their planes of stratification, at other times they are protruded in a direction parallel to these planes, and assume the form of beds. Some of the relations of these Granitic Veins to the rocks intersected by them are repre- sented at the left extremity of the Section. (a. 9.t) * Cases of Granite thus elevated at a period posterior to the deposition of Tertiary Strata, occur in the Eastern Alps, where the Transition, Seconda. ry, and Tertiary strata have all partaken of the same elevation which raised the central axis of the crystalline Granitic rocks. See Geol. Trans. N. S. Vol. III. Pl. 36.

A. 10. represents a dike and protruded mass of Granite, intersecting and overlying stratified rocks of the Primary and Transition series. A. 11. represents the rare case of Granite intersecting Red Sandstone, Oolite, and Chalk.* Sienite, Porphyry, Serpentine, Greenstone. Closely allied to Granite Veins, is a second series of irregularly injected rocks, composed of Sienite, Porphyry, Serpentine, and Greenstone (b. c. d. e.) which traverse the Primary and Transition formations, and the lower regions of the Secondary strata ; not only intersecting them in vari- ous directions, but often forming also overlying masses, in places where these veins have terminated by overflowing at the surface, (b'. c'. d'. e'.) The crystalline rocks of this series, present so many modifications of their ingredients, that numerous varieties of Sienite, Porphyry, and Green- stone occur frequently in the products of Eruptions from a single vent. The scale of our Section admits not of an accurate repre- sentation of the relations between many of these intruded rocks, and the strata they intersect; they are all placed, as the representation of the injections of Basaltic and Volcanic matter which that portion of the section is intended to illustrate. * An example of the rare Phenomenon of Granite intruded into the Chalk formation, in the hill of St. Martin, near Pont de la Fou in the Pyre. nees, is described by M. Dufrenoy in the Bulletin de la Société Géologique de France, Tom. 2. p. 73. At Weinböhla, near Meissen in Saxony, Prof. Weiss has ascertained the presence of Sienite above strata of Chalk; and Prof. Nauman states, that, near Oberau, Cretaceous rocks are covered by Granite, and that near Escheila and Neiderfehre, the Cretaceous rocks rest horizontally on Granite ; at both these places the Limestone and Granite are entangled in each other, and irregular portions and veins of hard Limestone, with green grains and cretaceous fossils, are here and there embedded in the Granite.

It should however be understood, distinctly, that some In- jections may have preceded the elevation of Strata to their present height, and that numerous and successive eleva- tions and injections, attended by various degrees of frac- ture and disturbance, have prevailed in various localities during all periods, and throughout all formations; from the first upraising of the earliest Primary rocks, to the most recent movements produced by existing Volcanoes. M. Elie de Beaumont has discovered probable evidence of no less than twelve periods of elevation, affecting the strata of Europe. Examples of the fractures and dislocations attending these movements, and producing faults, are represented in our Section by the lines designated by the letter l. Some of these fractures do not reach to the present surface, as they affected the lower beds at periods anterior to the deposition of more recent strata, which cover unconformably the sum- mits of the earlier fractures. (See 1. 1. 12. 13. 16. 17.) Basalt. A third series of Igneous Rocks is that which has formed dikes, and masses of Basalt and Trap, intruded into, and overlying formations of all ages, from the earliest Granites to the most recent Tertiary Strata.. These basaltic rocks sometimes occur as Beds, nearly parallel to the strata, into which they are protruded, after the manner represented in the carboniferous Limestone of our Section, f. 2. More frequently they. overspread the surface like expanded sheets of Lava. Our section gives examples of Trap under all these circumstances. At f. 1, it intersects and overlies Primary strata ; at f. 2. f. 3. f. 4. f. 5.. it stands in similar EXPLANATION OF PLATE I. relations to Transition and Secondary strata ; f. 6. represents an example of an extensive eruption of Basaltic matter, over Chalk and Tertiary strata, accompanied by an intru- sion of vast irregular masses of the same materials into the body of the subjacent Primary and Transition rocks. f. 7. represents strata of columnar Basalt, immediately beneath streams of cellular Lava, in regions occupied also by craters of extinct Volcanoes. f. 8. represents similar beds of columnar lava in the vicinity of active Volcanoes. Trachyte and Lava. The fourth and last class of intruded rocks, is that of modern volcanic Porphyries, Trachytes,* and Lavas. The undeniable igneous origin of rocks of this class forms the strongest ground-work of our arguments, in favour of the igneous formation of the older unstratified and crystalline rocks; and their varied recent products, around the craters of active Volcanoes, present gradations of structure, and composition, which connect them with the most ancient Porphyries, Sienites, and Granites. The simplest cases of volcanic action are those of Tra- chyte (g. l.) and of Lava (i. 5.) ejected through apertures in Granite; such cases prove that the source of volcanic fires, is wholly unconnected with the pseudo-volcanic re- sults of the combustion of coal, bitumen, or sulphur, in stratified formations, and is seated deep beneath the Primary rocks.t * The appellation of Trachyte has been given to a volcanic Porphyry, usually containing Crystals of glassy felspar, and remarkably harsh to the touch, (hence its name from rgzxus ;) it does not occur in Britain, but abounds in the neighbourhood of almost all extinct and active volcanic cra- ters. † The occurrence of angular fragments of altered Granite, embedded in Pillars of columnar Lava, in the valley of Monpezat in the Ardêche, shows S EXPLANATION OF PLATE 1. Craters. Our section represents three cases of Volcanic craters; the most simple (i. 5.) rising through Granite, or stratified rocks, at the bottom of the sea, and accumulating craters, which, like those of Lipari and Stromboli, Sabrina, and Graham Islands, are occasionally formed in various parts of the ocean.* The second case is that of volcanoes, which, like Etna and Vesuvius, are still in action on the dry land, (i. 1. to i. 4.) The third is that of extinct volcanoes, like those in Auvergne, (hé. h².) which, although there exist no historical records as to the periods of their last eruptions, show by the perfect condition of their craters, that they have been formed since the latest of those aqueous inunda- tions, that have affected the Basalt and Tertiary strata, through which they have burst forth. One great difference between the more ancient Basaltic eruptions and those of the Lava and Trachyte of existing volcanoes, is that the emission of the former, probably taking place under the pressure of deep water, was not accompa- nied by the formation of any permanent craters. In both cases, the fissures through some of which these Eruptions may have issued, are abundantly apparent under that these fragments were probably torn off during the upward passage of the Lava through fractures in the sordid Granite. At Graveneire, near Clermont, a strcam of Lava still retains the exact form in which it issued through a fissure in the side of a mountain of Granite, and overflowed the subjacent valley. Most accurate representations of this, and many similar productions of Volcanic Eruptions from the Granite of this District may be seen in Mr. Poulett Scrope's inimitable Panoramic Views of the Volcanic formations of Central France.. * Within the last few years, the Volcanic Cones of. Sabrina in the Atlantic, and of Graham Island in the Mediterranean, have risen suddenly in the sea and been soon levelled and dispersed by the Waves.. EXPLANATION OF PLATE I. the form of Dikes, filled with materials similar to those which form the masses that have overflowed in the Vicinity of each Dike.* Changes effected by the Igneous Rocks, on the Strata in contact with them. The peculiar condition of the rocks that form the side walls of Granitic Veins and Basaltic Dikes, affords ano- ther argument in favour of their igneous origin; thus wherever the early Slate rocks are intersected by Granitic Veins (a. 8.) they are usually altered to a state approxi- mating to that of fine-grained Mica-slate, or Hornblend- slate. The secondary and Tertiary rocks also, when they are intersected by basaltic Dikes, have frequently undergone some change; beds of Shale and Sandstone are indurated, and reduced to Jasper; compact Limestone and Chalk are converted to crystalline Marble, and Chalk-flints altered to a state like that resulting from heat in an artificial fur- nace.t In all these cases, the Phenomena appears to be through- out consistent with the theory of igneous Injection, and to be incapable of explanation on any other Hypothesis that has been proposed. A summary statement of the probable relations of the Granitic and Trappean Rocks to the other materials of the Globe, and to one another, may be found in De la Beche's Geological Researches, 1st Edit. Pag. 374, et seq. * In many Dikes the materials have been variously modified, by their mode of cooling, and differ from the masses which overflowed the surface. + Examples of this kind occur on the sides of Basaltic Dikes intersecting Chalk in the County of Antrim, and in the Island of Raghlin.

The continuity of stratified Rocks is always inter- rupted, and their level more or less changed on the opposite sides of a fault.

Their usual Order of Succession and Names are expressed in their respective places, and detailed descriptions of their several characters may be found in all good Trea- tises on Geology. The leading Groups of Formations are united by colours, marking their separation from the adjacent groups; and the same colours are repeated, in the headings above the figures of Plants and Animals that characterize the several series of Formations, to show the extent of the strata over which the Organic Remains of each Group are respectively dis- tributed. Although the deposites of Peat Bogs, and Calcareous Tufa are of too local a nature to be generally included in the series of stratified Rocks, they are represented in the Sec- tion (Figs. 31, 32,) because they sometimes operate locally to a considerable extent in adding permanent and solid matter to the surface of the Globe.

The bifid ungual bone (Kaup, Add. Tab. 11,) discovered with the other remains of Dinotherium, having the remarkable bifurcation which is found in no living Quadrupeds, except Pangolins, seems to have borne a Claw, like that of these animals, possessing peculiar advan- tages for the purpose of scraping and digging; and indicating functions, con.. current with those of the Tusks and Scapulæ.

It appears very probable, from more recent discoveries, that several other large and small animals, armed with a similar coat of mail, were co-inhabi- tants of the same sandy regions with the Megatherium.

In Fig. 1; a, b, c, d, are portions of ribs, and e, f, g, h, are fragments of sterno-costal bones (nat. size.) The spaces between these bones, are covered with the remains of skin; the Epidermis being represented by a deli- cate film, and the Rete mucosum by fine threads of white Carbonate of Lime; beneath these the Corium, or true skin, is preserved in the state of dark Carbonate of Lime, charged with black volatile matter, of a bituminous and oily consistence. 2. Magnified representation of the Epidermis and Rete mucosum. The fine superficial lines represent the minute wrincles of the Epidermis, and the subjacent larger decussating lines, the vascular net-work of the Rete mucosum. In Fig. 3, the Epidermis exhibits a succession of coarser and more distant folds or wrinkles overlying the mesh-work of the Rete mucosum. In Fig. 4, the Epidermis has perished, and the texture of the fine vessels of the Rete mucosum is exhibited in strong relief, over the black substance of the sub- jacent Corium, in the form of a net-work of white threads.* * Nothing certain has hitherto been known respecting the dermal covering of the Ichthyosauri; it might have been conjectured that these reptiles were incased with horny scales, like Lizards, or that their skin were set with dermal bones, like those on the back of Cros EXPLANATION OF PLAT PLATE 11.

(Conybeare.) 8. View of the lower jaw of Ichthyosaurus seen from codiles ; but as the horny scales of Fishes, and dermal bones of Crocodilean animals are preserved in the same Lias with the bones of Ichthyosauri, we may infer that if the latter animals had been furnished with any similar appendages, these would also have been preserved, and long ere this dis. covered, among the numerous remains that have been so assiduously collected from the Lias. They would certainly have been found in the case of the individual now before us, in which even the Epidermis, and vessels of the Rete Mucosum have escaped destruction. Similar black patches of petrified skin are not unfrequently found attached to the skeletons of Ichthyosauri from Lyme Regis, but no remains from any other soft parts of the body have yet been noticed. The preservation of the skin shows that a short interval only elapsed be- tween the death of the animal, and its interment in the muddy sediment of which the Lias is composed. Among living reptiles, the Betrachians afford an example of an order in which the skin is naked, having neither scales or dermal bones. In the case of Lizards and Crocodiles, the scaly, or bony coverings protect the skin from injury by friction against the hard substances with which they are liable to come into contact upon the land; but to the Ichthyosauri which lived exclusively in the sea, there would seem to have been no more need of the protection of scales or dermal bones, than to the naked skin of the Cetacea. In the case of Plesiosauri also, the non-discovery of the remains of any dermal appendages with the perfect skeletons of animals of that genus, leads to a similar inference, that they too had a naked skin. The same negative argument applies to the flying Reptile Family of Pterodac. tyles. EXPLANATION OF PLATES 12. 13. 25 A. Hollow conical Vertebræ of a fish. (Original.) B. C. D.

Oblique triangular facet on the lower margin of the front of the Atlas; this facet articulated with the first sub-vertebral wedge, placed be- tween the Atlas and Occiput. Between the Atlas and Axis, the two sub-vertebral facets formed a trian. gular cavity for the reception of a second wedge (Fig. 4. c.) and a similar, but smaller cavity received another wedge of the same kind, between the Axis and third Vertebra. This third wedge gave less support to the head, and admitted of more extensive motion than the second. All these three wedge-shaped bones are seen nearly in their natural position in a specimen from Lyme Regis, in the Collection of Sir P. G. Egerton. Fig. 4'.

In young animals this frontal facet is nearly smooth and flat; in older animals (3. b.) it is rugged and furrowed.

Fig. 4. c. Second sub-vertebral wedge articulating with the triangular cavity formed by the marginal facets of the Atlas and Axis.

Skeleton of the Trunk of a small Ichthyosaurus in the Fig. 5. Nearly flat articular surface of (probably) the third cervical ver- tebra of the same large Individual as Fig. 3. This surface of the bone has only a small cylindrical depression at its centre, instead of the deep, conical cup of the more flexible vertebræ, C. B. E. Near its upper margin is a wedge-shaped elevation (b) and near the infe- rior margin, a notch or furrow (a.) These salient and re-entering portions articulated with corresponding depressions and projections on the surface of the adjacent vertebra, and acted as pivots, admitting a limited amount of la- teral vibrations, and at the same time preventing any slip, or dislocation. Fig. 6. Concave surface of Fig. 5.; the wedge-shaped projection near its lower margin (a) must have articulated with a corresponding groove or depression on the front of the vertebra adjacent to it, like that at (Fig. 5. a.) As one surface only of these vertebræ had a conical cavity, the inter- vertebral substance must have formed a single cone, admitting in the neck but half the amount of motion, that the double cones of intervertebral matter allowed to the dorsal and caudal vertebræ, (C. B. E.) where greater flexure was required, to effect progressive motion by vibrations of the body and tail. These dispositions of the articulating facets of the cervical vertebræ, act- ing in conjunction with the three sub-vertebral wedges before described, afford an example of peculiar provisions in the neck of these gigantic Rep- tiles, to combine a diminished amount of flexure in this part, with an in. creased support to their enormous heads. It is probable that every species of Ichthyosaurus had peculiar variations in the details of the cervical vertebræ, and sub-vertebral wedges, and that in each species these variations were modified by age. In the Gavial Mr. Mantell has recently observed that the first caudal ver. tebra is doubly convex, like the last cervical vertebra in Turtles. These peculiar contrivances give to the animals in which they occur increased flexibility of the Tail and Neck.

On comparing this figure with those of P. Dolichodeirus at Pl. 16, 17. The following differences are obvious ::: 1. The head is very much larger and longer, being nearly one-half the length of the neck. 2. The vertebræ of the neck are thicker and stronger in: proportion to the greater weight they had to sustain. 3. The hatchet-shaped bones differ in form and size, as may be seen by comparing them with those of P. dolicho-. deirus. Pl. 19. Fig. 2. and Pl. 17. 4. The bones of the arm and thigh are shorter and stronger than in P. Dolichodeirus, and corresponding dif- ferences may be traced throughout the smaller bones of the Paddles; the general adjustment of all the proportions being calculated to produce greater strength in the P. Ma- crocephalus, than in the more slender limbs of P. Dolicho-, deirus. These differences are not the effect of age; as the two. specimens, from which they are here described, are nearly of the same lengtk. Fig. 2.

M. Brongniart, in his Terrain de l'Ecorce du Globe, 1829, has applied to this middle division the very appropriate name of Terrain Pæcilien, (from the Greek toxínos), a term equivalent to the names Bunter Sandstein, and Grés bigarré, which it bears in Germany and France; and indicating the same strata which, in England, we call the new Red Sand- stone. (See Plate 1. Section No. 17.) Mr. Conybeare, in his Report on Geology to the British Association at Oxford, 1832 (Page 379, and P. 405, Note,) has proposed to extend the term Pæcilitic to the entire Group of strata between the Coal formation and the Lias; including the five formations designated in our section (Pl. 1, No. 15, 16, 17, 18, 19,) by the names of New Red Conglomerate, Magnesian Limestone, Variegated Sand- stone, Shell Limestone, and Variegated Marl. Some com- mon appellative for all these formations has been long a desideratum in Geology; but the word Pæcilitic is in sound so like to Pisolite, that it may be better to adhere more literally to the Greek root wooxínos, and apply the common name of Poikilitic group to the strata in ques- tion.* * The general reception of such a common name for all these strata, and the reception of the Gruwacké series into the Cambrian and Salurian systems, as proposed by Professor Sedgwick and Mr. Murchison, fwill afford three nearly equal and most convenient groups or systems, into which the strata composing the Transition and Secondary series may respectively be divided; the former comprehending the Cambrian, Salurian, and Carboni. ferous systems, and the latter comprehending the Poikilitic, Oolitic, and Cretaceous Groups. EXPLANATION OF PLATE 26. PLATE 26. Ornithichnites, or foot-marks of several extinct species of birds, found in the New Red sand-stone of the Valley of the Connecticut.* (Hitchcock.) • In the American Journal of Science and Arts, January, 1836. V. XXIX. No. 2. Professor Hitchcock has published a most interesting account of his recent discovery of Ornithichnites, or foot-marks of birds in the New Red sand-stone of the valley of the Connecticut. These tracks have been found at various depths beneath the actual surface, in quarries of laminated flag-stones, at five places near the banks of this river, within a distance of thirty miles. The sand-stone is inclined from 5º, to 30°, and the Tracks ap- pear to have been made on it before the strata received their inclination. Seven of these tracks occur in three or four quarries within the space of a few rods square; they are so distinct that he considers them to have been made by as many different species, if not genera, of birds. (See Pl. 26a. Figs. 1–14. The footsteps appear in regular succession, on the continuous track of an animal in the act of walking or running, with the right and left foot always in their relative places. The distance of the intervals between each footstep on the same track is occasionally varied, but to no greater amount than may be explained by the Bird having altered its pace. Many tracks of different individuals and different species are often found crossing one another; they are some. times crowded like impressions of feet on the muddy shores of a stream, or pond, where Ducks and Geese resort. (See Pl. 26a. Figs. 12. 13. 14.) None of the footsteps appear to be those of Web-footed Birds; they most nearly resemble those of Grallæ, (Waders) or birds whose habits resemble those of Grallæ. The impressions of three toes are usually distinct, ex. cept in a few instances; that of the fourth or hind toe is mostly wanting, as in the footsteps of modern Grallæ. The most remarkable among these footsteps are those of a gigantic bird, twice the size of an Ostrich, whose foot measured fifteen inches in length, exclusive of the largest claw, which measured two inches. All the three toes were broad and thick. (Pl. 26a. Fig. 1. and Pl. 26b. Fig. 1.) These largest footsteps have as yet been found in one quarry only, at Mount Tom near Northampton; here, four nearly parallel tracks of this kind were disco. vered, and in one of them six footsteps appeared in regular succession, at 40 EXPLANATION OF PLATE 26*. The fossil tracks on this plate are all nearly on the same scale: viz. one twenty-fourth. The recent footsteps are on a larger scale. the distance of four feet from one another. In others the distance varied from four to six feet; the latter was probably the longest step of this gigantic bird while running Next in size to these are the footsteps of another enormous bird (Pl. 26a. Fig. 4.) having three toes of a more slender character, measuring from fifteen to sixteen inches long, exclusive of a remarkable appendage ex- tending backwards from the heel eight or nine inches, and apparently in- tended, like a snow.shoe to sustain the weight of a heavy animal walking on a soft bottom. (See Pl. 26b. Fig. 2.) The impressions of this appen. dage resemble those of wiry feathers, or coarse bristles, which seem to have sunk into the mud and sand nearly an inch deep; the toes had sunk much deeper, and round their impressions the mud was raised into a ridge several inches high, like that around the track of an Elephant in Clay. The length of the step of this Bird appears to have been sometimes six feet. On the other tracks the steps are shorter, and the smallest impression indicates a foot but one inch long, with a step of from three to five inches. (Pl. 26a. 2a 3. 5-14.) In every track the length of the step increases with the size of the foot, and is much longer in proportion than the steps of any existing species of birds; hence it is inferred that these ancient birds had a greater length of leg than even modern Grallæ. The steps at four feet asunder probably in- dicate a leg of six feet long. In the African Ostrich, which weighs 100lbs., and is nine feet high, the length of the leg is about four feet, and that of the foot ten inches. All these tracks appear to have been made on the Margin of shallow water that was subject to changes of level, and in which sediments of sand and mud were alternately deposited, and the length of leg, which must be inferred from the distance of the footsteps from each other, was well adapted for wading in such situations. No Traces of any Bones but those of fishes (Palæothrissum) have yet been found in the rock containing these footsteps, which are of the highest interest to the Palæonthologist, as they establish the new fact of the existence of Birds at the early epoch of the New Red sand-stone formation; and farther show that some of the most ancient forms of this class attained a size, far exceeding that of the largest among the feathered inhabitants of the present world, and were adapted for wading and running, rather than for flight.

Tubercles and Scales, illustrating the four new Orders of Fishes, extablished by Professor Agassiz. (Agassiz.) * Mr. Poulett Scrope has presented to the Geol. Soc. of London a series of Slabs selected from the tile quarries worked in the Forest Marble beds of the Oolite formation near Bradford and Bath. The surface of these beds is covered with small undulations or ripple markings, such as are common on the sand of every shallow shore, and also with numerous tracks of small animals. (apparently Crustaceans) which traversed the sand in various directions, whilst it was yet soft, and covered with a thin film of clay. These foot.marks are in double lines parallel to each other, showing two inden- tations, as if formed by small claws, and sometimes traces of a third claw. (See Pl. 266, Fig. 3.) There is often also a third line of tracks between the other two, as if produced by the tail or stomach of the animal touch. ing the ground. Where the animal passed over the ridges of the ripple markings or wrinkles on the sand, they are flattened and brushed down. Thus a ridge between b. and d. (Pl. 266, Fig. 3) has been flattened, and there is a hollow at e. on the steep side of the ridge, which may have been produced by the animal slipping down or climbing up the accli- vity.

Mr. Murchison has still more recently (1835) discovered remains of the Megalichthys, Holoptychius, and Coprolites, with several species of Unio, in the Wolverhampton Coal field. These great Sauroid fishes, which were first recognised at Edinburgh, in Sept. 1834, have also been detected in the Eng- lish Coal fields of Newcastle on Tyne, Leeds, and Newcastle under Lyne. 44 EXPLANATION OF PLATES 27*. 276.

Magnified view of the minute tubercles of Enamel which grew upon the skin; the decay of the skin * In the Lond. and Edin. Phil. Mag, Jan. 1836, the author has published a notice of his recent discovery of the jaws of four extinct species.of fossil fishes of the genus Chimæra, a genus hitherto unknown in a fossil state. The only known species (C. montrosa) approximates most nearly to the family of Sharks; and is found pursuing Herrings and other migratory fishes. The Chimæra is one of the most remarkable among living fishes, as a link in the family of Chondropterygians; and the discovery of a similar link, in the geological epochs of the Oolitic and Cretaceous formations, shows that the duration of this curious genus has extended through a greater range of geological epochs, than that of any other genus of fishes yet ascer- tained by Professor Agassiz, and leads to important considerations in Physio- logy. The Chimæra partakes of one remarkable character with the Cestracion Phillippi, whereby this species alone, among living Sharks, is connected with the extinct forms of that family, in having the first ray of the dorsal fin enlarged into a strong bony spine armed with sharp hooks, like the Ichthyo- dorulite of the earliest fossil Sharks.

The mouth of these and all the other numerous extinct species of Sharks in the family of Cestracionts, was lined with a pavement of similar powerful teeth, forming a most efficient apparatus, for crushing the shells of Crustacea and Conchifera, which probably formed their principal food. The surfaces of the Enamel are often worn away, like that at Pl. 27º. fig. 3. The strength and efficacy of these teeth, viewed as Intru- ments for crushing shells, is very remarkable. Beneath the Enamel, the body of each tooth is composed of a strong mass of bone. (Miss F. C. Burgon. Original.) PLATE 28. V. I. p. 230.

Other Sections of the Siphuncle at b. d. e. f. show the calcareous Grit within its cavities to be contracted at its passage through the collars of the transverse plates, and most enlarged midway between one transverse plate and another. · This fossil affords two proofs that no communication existed between the interior of the Siphuncle and that of the Air-chambers.. 1st. the calcareous: sheath of the Siphuncle is seen at d. e. f. completely enclosing the calcareous grit which forms the cast within it. 2dly, had there been any communica- tion between the interior of the siphuncle, and that of the air-chambers, these chambers must have received some portion of the materials of the grit that have filled this Siphuncle : not. a particle of grit is found in any one of the adjacent air-chambers, but they are all lined, and some of them nearly filled with a crystalline deposite of Carbonate of Lime, disposed in uniform plates around the interior of each chamber, and around the Siphuncle. See Fig. 2. c. cl. a. a'. a?. a3. and Fig. 3. d-k. This deposite can only have been formed from water charged with carbonate of lime, introduced by infiltration, after the interment of the shell, and filling the chambers which are thus uniformly invested. 56 EXPLANATION OF PLATES 33, 34.

Drawing of the animal of the Nautilus Pompilius, pre- pared at my request by Mr. Owen, to show the manner in which the siphuncle terminates in the Pericardium. (Ori- ginal.) * The successive zones of this dark Spar show that the Lime composing it was introduced by slow and gradual infiltrations into the cavity of the air-chambers.. Hence it follows that no communication existed between the Siphuncle and these chambers, at the time when this Pipe was filled with the Auid mud, that has formed a cast of Lias within it. As the fractures across the Siphuncle in the 2d and 3d chambers are filled only with spar, of the same kind as that within these Chambers, these frac. tures could not have existed, when the Mud of the Lias formation entered the Siphuncle, without admitting it also into the chambers adjacent to them.

The overflowings of this pericardial fluid may pass out through the orifices marked by the bristles, c. c. + This upper portion or neck of the Siphuncle, has the form of a flattened canal, with thin Parietes of the same substance as the Pericardium; when the animal expands itself at the bottom of the sea, this neck is probably closed by the lateral pressure of the gizzard, k, and ovary, ) and so acts instead of a valve to prevent the return of the pericardial fluid into the Siphuncle. At such times the deep-sea water must press with great force on the exterior of the Pericardium, and tend to force the pericardial fluid into the Siphuncle; but as an equal amount of pressure is applied simultaneously to the Ovary and 58 EXPLANATION OF PLATES 35. 36.

One object of this Plate and of many of the figures at Pl. 37. is to show the manner in which the external shell is for- tified by Ribs and Flutings, (PP. 257. 258.) and farther sup- ported by the edges of the internal transverse plates, that form the air-chambers. See V. I. p. 263, Note. (Original.) PLATE 36. V. I. p. 256. Note. Longitudinal section of another shell of Ammonites obtusus from the Lias at Lyme Regis. (Original.) The greater part of the outer chamber, and the entire ca- vities of the air-chambers are filled with calcareous spar, and the Siphuncle, (preserved in a carbonaceous state,) is seen passing along the entire dorsal margin to the com- mencement of the outer chamber. See V. I. p. 265, Note. Von Buch has found evidence to show that the mem- branous siphuncle of Ammonites was continued to a con- siderable distance along the outer chamber, beyond the last or largest transverse Plate. This discovery accords with the analogies afforded by the membranous neck of the siphon of the N. Pompilius, which is continued along the outer chamber from the last transverse Plate to the Pericar- dium. See Pl. 34. q.* Gizzard, the lateral pressure of these two organs on the neck of the Siphun- cle would tend to close it with a force exactly counterbalancing the external pressure on the Pericardium. * As the body of the animals that inhabited the Ammonites was more elongated than that of those inhabiting the shells of Nautili, in consequence of the smaller Diameter of their outer Chamber, the place of their Heart was probably more distant from the last transverse Plate, than that of the Heart of Nautili; and the membranous Siphon connected with the Pericar- dium consequently longer.

The figures in this Plate are selected to exemplify some of the various manners in which the shells of Ammonites are adorned and strengthened by ribs, and flutings, and bosses. In Vol. I. p. 257, instances are mentioned of similar contrivances which are applied in Art to strengthen thin plates of metal. Workers in Glass have also adopted a similar expedient in their method of fortifying small wine flasks of thin glass, made flat, and portable in the pocket, with a series of spiral flutings passing obliquely across the sides of the flask, as in many of the flattened forms of Ammonite. Similar spiral flutings are introduced for the same purpose on the surface of thin glass pocket smelling- : bottles. In other glass flasks of the same kind which are made in Germany, the addition of bosses to the surfaces of the flat sides of the bottles, produces a similar double result of ornament and strength.

This position agrees with that of the animal figured by Blainville, if we suppose the caudal portion of the latter to have been lost. On each side of the body are two expansions that act like Fins, as in the Sepiole. Beneath the neck is the aperture of the Funnel. In 64 EXPLANATION OF PLATE 44. Fig! 3.

Some recent observations of M, Dujardin have induced him to refer the Animals which construct the Miliola and some other microscopic fora- miniferous shells, to a new Class of animals of a lower degree than the Radiata, and possessing a locomotive power by means of minute tentacular filaments.

These alveolar plates form the internal chambers of the Sepiostaire, and represent the transverse plates of the Alveolus in Belemnites, and other chambered shells; but as the Sepiostaire has no siphuncle, its chambers seem not subservient, like those of the Belemnite, to the purpose of varying the specific gravity of the animal; the intervals between its plates are occupied by an infinite number of thin winding partitions standing perpendicularly between the lamellæ.

EXPLANATION OF PLATE 46". 77 V. l. of a nodule of Iron ore from Coalbrook Dale. p. 299.* (Original.) parently a fragment of the proboscis; the legs are all imperfect; the thorax is very large, and only its inferior surface is visible, being exposed by the removal of the pectoral portion of the trunk; this surface is covered with irregular indentations, which represent the hollow interior of a series of spinous tubercles, and verrucose projections on the back of the thorax. In the centre of the thorax is a compound depression larger than the rest, indicating the presence of a corresponding projection on the back. Among living Curculionidæ irregular tubercles and projections of this kind occur on the thorax of the Brachycerus apterus. The left Elytron only is distinctly visible, embracing with its margin the side of the Abdomen; its outer surface is irregularly and minutely punctate. Two spinous tubercles project from near its posterior extremity, and a cor- responding tubercle from the extremity of the right elytron. Similar spines occur on the Elytrons of Brachycerus; and of some Curculionidee of N. Hol- land. The abdominal rings are very distinct, I shall designate this Insect by the provisional name of Curculioides Presvicii, M. Audouin exhibited at the meeting of the Naturforscher at Bonn, in September, 1835, a beautiful wing of a neuropterus Insect, in a nodule of clay Iron stone, apparently also from the neighbourhood of Coalbrook Dale, which had been purchased at the sale of Parkinson's collection by Mr. Man- tell, and transmitted by him to M. Brongniart. This wing is nearly three inches long, and closely resembles that of the living Corydalis of Carolina and Pennsylvania; it is much broader and nearly of the length of the wing of a large Dragon Fly. * Several specimens of this species are in the collection of Mr. Wm. Anstice at Madely Wood, Our figure is taken from a cast or impression of the back of the animal in Iron stone, in which the transverse lines across the abdominal segment are not very apparent; other specimens exhibit deep transverse flutings, externally resembling the separate segments of the back of a Trilobite, but apparently not dividing the shell into more than one abdominal Plate, nor admitting of flexure like the articulating segments of a Trilobite.

A fossil Fly from the fresh-water formation of Aix in Provence, in the collection of Mrs. Murchison, Mr. Curtis considers this Fly to be of the same spe- cies with one of those engraved in Fig. 11 of his Plate of Insects from this locality, in Jameson's Journal, Oct. 1829. (Originala) Although it agrees with no living genus, he thinks it undoubtedly belongs to the family of Tipulidæ, of this animal, form a character wherein it approaches nearer than the living Limulus to the structure of Trilobites. The articulation of the long awl. shaped tail with the body in Fig. 3, and in other specimens is very distinct. This Limulus is the Entomolithus monoculites of Martin, (Petrifacta Derbi. ensia, Tab. 45, Fig. 4.) and Belinurus bellulus of König, (Icon. Sect. Pl. XVIII. No. 230.) M. Parkinson, Org. Rem, iji. Pl. XVII. Fig. 18, has figured a similar fossil from Dudley, in iron stone of the Coal formation. * Mr. Rr. C. Taylor mentions the occurrence of the wing covers of Beetles in the shale of the Danby Coal pits, in the Eastern Moorlands of Yorkshire. This shale has nearly the same place in the Oolitic series as the Stonesfield slate. See Loudon's Mag. Nat, Hist. V. iii. P. 361. In the private collection of Dr. De Siebold at Leyden, I saw in Oct. 1835, o most beautiful and unique specimen of Buprestis, from Japan, about an inch long, converted to Calcedony. Even the antennæ and portions of the legs are distinctly preserved. In the same collection are fragments of solicified trees, bored with tubular cavities, apparently by the larvæ of animals of this kind.; and within these cavities, a quantity of dust, produced by the boring, was observed by M. Brongniart to be converted to Calcedony. From this circumstance we may conjecture that the perfect inscct was lodged in a similar tube, when it hecame transformed into Calcedony. The surface of this Insect is covered with clusters of minute concentric rings of Calcedony (Orbicules of Brong- niari) so common in silicified fossil shells.

This specimen has been corroded with acid, and consequently has lost the superficial Corrugations and in his admirable Monograph on Crinoidea, p. 97. "The mechanism of the joints of the side arms, where these insert into the column, is well worthy of notice, particularly in old specimens. In the earlier stage of their for: - mation, the side arms being very short, and having then little weight, a less firm mode of adhesion to the column than becomes requisite at a sub- sequent period, being then sufficient, we no not find more than one joint lodged in a socket, or concave impression on the column; but when increase of size renders a stronger support necessary, two or three suce ceeding joints of the side arms become embedded in this socket, (for which its extension as already noticed allows room) and these joints instead of being arranged in a series branching off at right angles from the column, become oblique, their direction inclining upwards, so as to aid in bearing the additional weight. The first joint of the side arms, where thus ob. Tiquely inserted in the columnar socket, have that portion of their circum. ference which is presented towards the upper part of the column, trun. cated, in such a curve as may fit them to the concavity of the impression where they rest against it. The surface of these joints, which fit into the columnar impression, is smooth, being destined for adhesion only, but the articulating surface between the contiguous joints, where motion also is to be allowed, ex. libits the usual mechanism of radiated ridges and furrows. These joints are convex on the side nearest the column, and concave on that most re. mote. 82 EXPLANATION OF BLATES 48. 49. Tubercles which appear on the surface of Fig. 6. (Original.) X.

Thompson has more recently conjectured that the Pentacrinus Europæus, which in early life is fixed by its stem to other bodies, is produced from the ovum of the Comatula, and becomes afterwards detached, and forms a perfect Comatula, capable of moving freely in the Ocean; at one time crawling amongst sub-marine Plants, at others floating, or swimming like Medusæ.

Fragment of the bark on the trunk of a Sigillaria, from Earl Fitzwilliam's coal-mine at Elsikar, near Rotherham. In this mine many large trunks are seen inclined in all directions, and some nearly ver- tical. (See V. I. p. 353, Note.) The bark is converted into a thin lamina of coal, and remains attached to the lower portion of this specimen. It exhibits on its outer surface scars formed by the articulations of the bases of leaves; these are penetrated near their centre by three apertures for vessels that passed from each leaf into the trunk. The decorti- cated upper part of this specimen presents an im- pression of its striated internal surface, and exhibits beneath each scale two oblong parallel apertures, through which the vessels from a leaf penetrated the trunk. Scale one-half. (Original.) The substance of the trunk must have been in a state of decay, before the mud, which is now har- dened into shale, could have entered the interior of the bark. When trunks of this kind are inclined at an angle exceeding 45°, they are usually dis- tended with sand-stone, or sandy shale; when at a less angle than 45°, they are most commonly com- pressed, and have only a thin flat portion of shale, formed of indurated mud within their bark. The bark, wherever it has not perished, is converted to coal. 2. Articulating leaf-scar on the exterior of the bark of another large trunk of Sigillaria from Elsecar. Nat. * M. Ad.

On comparing this scar with those upon the bark of Fig. 2, it may be seen that the different modes of articulation of the leaves with the cortical integument present obvious characters, on which specific distinctions may perhaps most easily be esta- blished, in this very obscure and curious family of extinct plants. See various figures of these leaf- scars in Lindley and Hutton's Fossil Flora, Plates 55. 56. 57. 71. 72. &c.

Drawn from a plaster cast of an impression on sand-stone, in the Museum of the Royal Society of Edinburgh from the Coal formation at Cragleith. This sand-stone has formed a natural mould on the outer surface of a stem, which has entirely perished; our cast gives a fac-simile of the small rhomboidal scales, and of three large round scars on the exterior of the trunk. This impression has been figured, in an inverted position, by Mr. Allan in Vol. IX. Trans. Royal Soc. Edin. 1823. Pl. XIV. p. 236. (Original.). Our figure represents the trunk in its natural position. In the centre of each scar is a cavity, indicating the place of attachment of a cone. The upper portion of each scar is marked with furrows, produced by pressure of the long radiating scales at the bottom of the cone. This pressure has nearly obliterated the smaller rhomboidal scales of the bark, in those parts where the furrows are deepest; on the lower portion of the scars, the scales of the bark have been but slightly modified by pressure of the cone. EXPLANATION OF PLATE 56. Fig. 4. A single scar formed by the attachment of a cone of another species, Ulodendron Lucasii, (nobis,) dis- covered by Mr. Lucas in the S. Wales Coal field near Swansea. Some scales and speared-shaped leaves of the trunk are still preserved around the mar- gin of this scar. As the bark has fallen off, we have only the impression of its inner surface. This sur- face exhibits small apertures, through which vessels entered from beneath the bark-scales into the trunk. On the upper part of the disk, the traces of many of these vessels have been obliterated by pressure of the cone. Scale one-fourth. (Original.) Fig. 5. Ulodendron Stokesii. (nobis.) A large oval scar, (44 inches in its longer, and 3} inches in its shorter diameter) preserved in shale from an unknown lo- cality in the English Coal Formation. On the margin of this scar are the remains of rhomboidal scales, and impressions of scales, and a few small leaves. Within the disk a few fragments only of the bark remain near its upper margin. Near its centre, is the mark of the insertion of the stem of a large cone. The lower half exhibits a series of small tubular cavities, marking the place of vessels which passed from the bark into the trunk, one beneath each of the bark-scales that have fallen off. In the upper half of the Scar, there are but slight traces of these cavities, and the surface is marked with furrows, produced by pressure of the long radiating scales of the base of the cone.

The extensive Iron foundries which cover the sur- face of this district, and the greater part of the manufactures in the adjacent town of Birmingham, originate in the Coal and Iron ore, with which the strata of shale in this Coal basin are richly loaded. The Dudley Limestone here found immediately below the Coal formation, occurs usually at a much greater depth in the series. The Mountain Lime- stone, Old red Sand-stone, and Ludlow rocks, are here wanting. (See Pl. 66, Fig. 1.) Fig. 2. Section showing the basin-shaped disposition of the Carboniferous strata in S. Wales. (Rev. W. D. Conybeare.) The richest beds of Coal and Iron ore are placed almost immediately above the Mountain limestone. (See pp. 59, 396.)

The advantages * The lower and richest beds of this Coal district are not only raised to the surface, and rendered easily accessible around the external margin of the basin, but are also brought within reach in consequence of another im- portant elevation, along an anticlinal line, running nearly E. and W. through a considerable portion of the interior of the basin, in the direction of its. longer diameter. + I feel it a public duty to make known an act of Mr. Buddle, which will entitle him to the gratitude of posterity, and has set an example, which, if ge- nerally followed in all extensive collieries, will save the lives of thousands of unfortunate miners, that must otherwise perish for want of information, which can, at this time, be easily recorded for their preservation. This eminent Engia EXPLANATION OF PLATE 67. 105 resulting from these interruptions of the continuity of the strata are pointed out in pp. 406, 407. A large portion of the surface of these strata near Newcastle is covered with a thick bed of diluvial Clay interspersed with Pebbles, in the manner re- presented at the top of this Section. The effect of this Clay must be to exclude much rain water that would have percolated downwards into the Coal mines, had strata of porous Sand-stone formed the actual surface. Plate 67. V. I. p. 417.

Every practical Miner is too well acquainted with the danger of approaching ancient workings in consequence of the accumulation of water in those parts from which Coal has been removed. The sudden irruption of this water into a mine adjacent to such reservoirs is occasionally attended with most calamitous and fatal results. See History of Fossil Fuel, the Col. lieries and Coal Trade, 1835. P. 249 et seq.. The dictates of humanity which prompt us to aid in the preservation of human life, nu less than the economical view of rendering available at a future time the residuary portions of our beds of Coal, which will not now repay the cost of extracting them, should induce all proprietors and other persons connected with Coal Mines, and especially Engineers and Coal Viewers, to leave to their successors a legacy, which will to them be precious, by pre- serving minute and exact records of the state of the coal in their respective districts. It can, however, scarcely be expected, that such measures will be generally and systematically adopted throughout the many Coal fields of this country, unless the subject be legislatively taken up by those official persons, whom it behooves, as guardians of the future welfare of the nation, to institute due measures, whilst the opportunities exist, for preventing that loss of life and property, which a little attention bestowed in season, will pre- serve to posterity. 106 EXPLANATION OF PLATE 67. stratified rocks, terminated abruptly by a cliff on the sea-shore; this figure is intended to illustrate two causes of the production of Springs by descent of water from porous strata at higher levels; the first, producing discharges in valleys of Denudation, along the line of junction of porous with imperme- able strata ; the other, by the interruption offered to descent of water by Faults that intersect the strata. The Hills A, C, are supposed to be formed of a permeable stratum a, a', a", resting on an imper- meable bed of Clay b, b', 6". Between these two Hills is a Valley of Denudation, B. Towards the head of this Valley the junction of the permeable stratum a, a', with the Clay bed b, b', produces a spring at the point S.; here the intersection of these strata by the denudation of the valley affords a perennial issue to the Rain water, which falls upon the adjacent upland plain, and percolating down- wards to the bottom of the porous stratum a, a', accumulates therein until it is discharged by nume- rous springs, in positions similar to S, near the head and along the sides of the valleys which intersect the junction of the stratum a, a', with the stratum b, b'.

The Rain that falls upon this Hill between H, and D, descends through the porous stratum a", to the subjacent bed of Clay bu, * The term Combe, so common in the names of upland Villages, is usually applied to that unwatered portion of a valley, which forms its continuation beyond, and above the most elevated spring that issues into it; at this point, or spring head, the valley ends, and the Combe begins. The conveniences of water and shelter which these spring-heads afford, have usually fixed the site of the highest villages that are planted around the margin of elevated plains. EXPLANATION OF PLATE 67. 107 The inclination of this bed directs its course towards the Fault H, where its progress is intercepted by the dislocated edge of the Clay bed b', and a spring is formed at the point f. Springs originating in causes of this kind are of very frequent occurrence, and are easily recognised in cliffs upon the sea-shore.* In inland districts, the fractures which cause these springs are usually less apparent, and the issues of water often give to the Geologist notice of Faults, of which the form of the surface affords no visible indication.

The mean direction of the greatest number of them is nearly from E. N. E. to W. S. W. They are inter- sected nearly at right angles by other and less nu- merous Veins called Cross Courses, the contents of which usually differ from those of the E. and W. veins, and are seldom metalliferous. The Granite and Killas and other rocks which in- tersect them, e. g. Dikes and intruded masses of more recent Granite, and of various kinds of por- phyritic rocks called Elvans (see Pl. 1, a 9. b. c.) are considered to have occupied their present relative positions, before the origin of the fissures, which form the metalliferous Veins, that intersect them all. (See V. I. p. 411.* * In Vol. I. P. 413, Note, a reference is made to some important obser- vations by Mr. R. W. Fox on the Electro magnetic actions which are now going on in the mines of Cornwall, as being likely to throw important light on the manner in which the ores have been introduced to metallic veins. The following observations by the same gentleman in a recent communi- cation to the Geological Society of London, (April, 1836,) appear to contain the rudiinents of a Theory, which, when maturely developed, promises to offer a solution of this difficult and complex Problem. “ If it be admitted that fissures may have been produced by changes in the temperature of the earth, there can be little difficulty in also admitting that electricity may have powerfully influenced the existing arrangement of the contents of mineral veins. How are we otherwise to account for the re. lative positions of veins of different kinds with respect to each other, and likewise of their contents in reference to the rocks which they traverse, and many other phenomena observable in them?

See V. I. p. 421. Note. (Original.) in combination with the sulphuric and muriatic acids, being very soluble in water, are, in this state, capable of conducting voltaic electricity; so, if by means of infiltration, or any other process, we suppose the water to have been impregnated with any of these metallic salts, the rocks containing dif. ferent salts would undoubtedly become in different or opposite electrical conditions ; and hence, if there were no other cause, electric currents would be generated, and be readily transmitted through the fissures containing water with salts in solution; and decompositions of the salts and a trans. ference of their elements, in some cases, to great distances, would be the na- tural result. But, on the known principles of Electro-magnetism, it is evi. dent that such currents would be more or less influenced in their direction and intensity by the magnetism of the earth. They cannot, for instance, pass from N. to S. or from S. to N. so easily as from E. to W. but more so than from W. to E. The terrestrial magnetism would therefore tend, in a greater or less degree, to direct the voltaic carrents through those fissures which might approximate to an east and west bearing, and in sepa- rating the saline constituents, would deposite the metal within or near the electro.negative rock, and the acid would be determined towards the electro. positive rock, and probably enter new combinations. Or, the sulphuric acid might, by means of the same agency, be resolved into its elements; in which case the sulphur would take the direction of the metal, and the oxy. gen of the acid, and in this way, the metallic sulphurets may have probably their origin; for, if I mistake not, the metallic sulphates, supposing them to have been the prevailing salts, as at present, would be fully adequate to supply all the sulphur required by the same metals to form sulphurets; in- deed more than sufficient, if we deduct the oxide of tin, and other metalli- ferous oxides found in our mines. The continued circulation of the waters would, in time, bring most of the soluble salts under the influence of these currents, till the metals were in great measure separated from the solvents, and deposited in the East and West veins, and near the rocks to which they were determined by the electric currents." In a Letter to the Author upon this subject (June 29, 1836,) Mr. Fox farther remarks: VOL. II.-10 110 EXPLANATION OF PLATE 69. PLATE 69. V. I. p. 422. Fig. 1.

I. p. 423. Note. (Hericart de Thury.) "It should be observed that in proportion as the deposition of the metals proceeded, the voltaic action must necessarily have been considerably aug. mented, so as to render it highly probable that the metals were chiefly de- posited at rather an early period in the history of the containing veins; and their intersection by other veins seems to strengthen this probability.” Mr. Fox has found by experiment that when a solution of muriate of Tin is placed in the voltaic current, a portion of the metal is determined towards the negative pole, whilst another portion in the state of an oxide passes to the positive pole. This fact appears to him to afford a striking illustration of the manner in which Tin and Copper have been separated from each other in the same vein, or in contiguous veins, whilst these metals also very commonly occur together in the same vein.
