 ... the horse-type is exactly and precisely that which could have been predicted from a knowledge of the principles of evolution. And the knowledge we now possess justifies us completely in the anticipation, that when the still lower Eocene deposits, and those which belong to the Cretaceous epoch, have yielded up their remains of ancestral equine animals, we shall find, first, a form with four complete toes and a rudiment of the innermost or first digit in front, with probably, a rudiment of the fifth digit in the hind foot;[6] while, in still older ...

... of the golden age of the reptiles. At the end of the Jurassic the land begins to rise once more. The warm, shallow seas drain off into the deep oceans, and the moist, swampy lands are dried. The emergence continues throughout the Cretaceous (Chalk) period. Chains of vast mountains rise slowly into the air in many parts of the earth, and a new and comparatively rapid change in the vegetation—comparable to that at the close of the Carboniferous—announces the second great revolution. The ...

... Coal deposits of more recent age are numerous, but in general they have had less time in which to undergo the processes of condensation and refinement, and hence their general grade is lower. In the western United States there are great quantities of subbituminous coal of Cretaceous age, and of Tertiary lignites which have locally been converted by mountain upbuilding into bituminous and semibituminous coals. Jurassic coals are known in many parts of the world outside of North America, and lignites of Tertiary age are widely ...

... the Palaeontographical Society for 1851, I will not here enter on it: I will only remark, that the Lepadidae or Pedunculated Cirripedes are much more ancient, according to our present state of knowledge, than the Balanidae. The former seem to have been at their culminant point during the Cretaceous Period, when many species of Scalpellum and Pollicipes, and a singular new genus, Loricula, existed; Pollicipes is the oldest genus, having been found in the Lower Oolite, and, perhaps, even in the Lias. The fossil species ...

... hidden under laterite. The median zone is composed largely of crystalline rocks with granites and some Palaeozoic unfossiliferous rocks. The littoral zone contains the only fossiliferous strata. These are of Tertiary and Cretaceous ages, the latter rocks resting on a reddish sandstone of older date. The Cretaceous rocks of the Dombe Grande region (near Benguella) are of Albian age and belong to the Acanthoceras mamillari zone. The beds containing Schloenbachia inflata are referable to the Gault. Rocks of Tertiary age ...

... might add, came to your province some three million years ago and is now being exhumed from one of the cut-banks of the Red Deer River. He belongs to the Mesozoic order of archisaurian gentlemen known as Dinosauria, and there's about a car-load of him. This interest in one of your cretaceous dinosaur skeletons would imply, of course, that I'm wedded to science. And I am, though to nothing else. I'm as free as the wind, dear lady, or I wouldn't be holidaying here with a tractor-plow that makes my legs ache and a prairie Penelope, who, for some reason or other, has the power of making ...

... to the recognition of the changes connected with the Periods. As I shall have occasion hereafter to enter into this subject more at length, I will only allude briefly here to the circumstances. In so doing I am anticipating the true geological order, because I must treat of the Jurassic and Cretaceous deposits, which are still far in advance of us; but as it was by the study of these deposits that the circumscription of the Periods, as I have defined them above, was first ascertained, I must allude ...

... the length of that period in years. The relative duration is clear, tho the absolute duration may not be definable. The attempt to affix any precise date to the period at which the chalk sea began or ended its existence is baffled by difficulties of the same kind. But the relative age of the cretaceous epoch may be determined with as great ease and certainty as the ...

... which form the Balearic Isles fall naturally into two divisions. There is an older series, ranging from the Devonian to the Cretaceous, which is folded and faulted and forms all the higher hills, and there is a newer series of Tertiary age, which lies nearly horizontal and rests unconformably upon the older beds. The direction of the folds in the older ...

... through a succession of geological epochs, sedimentation had proceeded so that the accumulations of Palaeozoic and Mesozoic times had collected in the geosyncline formed by their own ever increasing weight. The site of the future Laramide range was in late Cretaceous times occupied by some 50,000 feet of sedimentary deposits; but the limit had apparently been attained, and at this time the Laramide range, as well as its southerly continuation into the United States, the Rockies, had their beginning. Chamberlin and ...

This stickiness was apparently due to the presence of innumerable lumps of a transparent, gelatinous substance, consisting of minute granules without discoverable nucleus or membranous envelope, and interspersed with cretaceous coccoliths. After a description of the structure of this substance and its chemical reactions, he makes a careful proviso against confounding the statement of fact in the description and the interpretation which he proceeds to ...

... thickness of the peat-bog represents a phase in the progressive change from wood-tissue to lignite, using this term with its common signification to indicate, not necessarily carbonized ligneous tissue, but plant-tissue that belongs to a past though modern geological age—i.e., Tertiary, Cretaceous, Jurassic, or Triassic. These lignites or modern coals are only peat beds which have been buried for a longer or shorter time under clay, sand, or solidified rock, and have progressed farther or less far on the road to coal. As ...

... valleys are some fifteen miles of chalky hills almost bare of trees, a dreary track to cross at any time, but especially detestable when the dust lies thick upon the white road and the summer sun is blazing overhead. But how delightful is the contrast when, going down at length from these cretaceous uplands, where even the potato plants look as if they had been whitewashed, you see below the verdant valley of the Dronne, that seems to be blessed with eternal spring, the gay flash of the winding stream, the grand rocks that appear to be standing ...

... nor is there any authority on earth (always excepting the Dean of Christ Church) which could make it credible to me. I am sick of Mr. Canning. There is not a "ha'porth of bread to all this sugar and sack." I love not the cretaceous and incredible countenance of his colleague. The only opinion in which I agree with these two gentlemen is that which they entertain of each other. I am sure that the insolence of Mr. Pitt, and the unbalanced accounts of Melville, ...

... established by palaeontological proofs. He thinks he has been able to fix upon the true point of division between the Mesozoic and Cenozoic ages, and to prove that coal was deposited through about 7,000 feet of Cretaceous and about 4,500 feet of Cenozoic beds. Mr. Powell's literary style is excellent—not involved, but clear and energetic. He was wise to abandon the idea of publishing an itinerary, which would, as he says, "encumber ...
