In the previous chapter we have seen that, on general grounds, evolution as applied to man is untenable; and that the theory of creation is more rational and less liable to obje...
21. CHAPTER VI.That age of the world's history which, from its richness in accumulations of vegetable matter destined to be converted into coal, has been named the Carboniferous, is in relatio...
29. CHAPTER XIV.The geological record, as we have been reading it, introduces us to primitive man, but gives us no distinct information as to his origin. Tradition and revelation have, it is tr...
22. CHAPTER VII.The immense swamps and low forest-clad plains which occupied the continental areas of the Northern Hemisphere, and which we now know extended also into the regions south of the...
20. CHAPTER V.Paradoxical as it may appear, this period of geological history has been held as of little account, and has even been by some geologists regarded as scarcely a distinct age, jus...
19. CHAPTER IV.By English geologists, the great series of formations which succeeds to the Cambrian is usually included under the name Silurian System, first proposed by Sir Roderick Murchison...
26. CHAPTER XI.Plant-life in the Tertiary approaches very nearly to that of the Modern World, in so far as its leading types are concerned; but in its distribution geographically it was wonder...
24. CHAPTER IX.The waters of the Mesozoic period present features quite as remarkable as the land. In our survey of their teeming multitudes, we indeed scarcely know where to begin or whither...
25. CHAPTER X.Between the Mesozoic and the next succeeding time which may be known as the Neozoic or Tertiary,[AG] there is in the arrangements of most geologists a great break in the success...
18. CHAPTER III.Between the time when _Eozoon Canadense_ flourished in the seas of the Laurentian period, and the age which we have been in the habit of calling Primordial, or Cambrian, a great...
17. CHAPTER II.The dominion of heat has passed away; the excess of water has been precipitated from the atmosphere, and now covers the earth as a universal ocean. The crust has folded itself i...
27. CHAPTER XII._In_ closing these sketches it may seem unsatisfactory not to link the geological ages with the modern period in which we live; yet, perhaps, nothing is more complicated or enco...
28. CHAPTER XIII.Turning from these difficult questions of time, we may now look at the assemblage of land-animals presented by the Post-glacial period. Here, for the first time in the great ser...
16. CHAPTER I.The title of this work is intended to indicate precisely its nature. It consists of rough, broad sketches of the aspects of successive stages in the earth's history, as disclose...
23. CHAPTER VIII.Physically, the transition from the Permian to the Trias is easy. In the domain of life a great gulf lies between; and the geologist whose mind is filled with the forms of the P...
