Page xlvi - Palaeozoic epoch as at present, and those seemingly sudden appearances of new genera and species, which we ascribe to new creation, may be simple results of migration. It may be so; it may be otherwise. In the present condition of our knowledge and of our methods, one verdict — " not proven, and not proveable "• — must be recorded against all the grand hypotheses of the palaeontologist respecting the general succession of life on the globe.
Page lii - It negatives those doctrines ; for it either shows us no evidence of any such modification, or demonstrates it to have been very slight ; and as to the nature of that modification, it yields no evidence whatsoever that the earlier members of any long-continued group were more generalised in structure than the later ones.
Page xlvi - There seems, then, no escape from the admission that neither physical geology nor palaeontology possesses any method by which the absolute synchronism of two strata can be demonstrated. All that geology can prove is local order of succession. It is mathematically certain that, in any given vertical linear section of an undisturbed series of sedimentary deposits, the bed which lies lowest is the oldest. In...
Page 222 - The relative position in the silt, from which the canoes were exhumed, could help us little in any attempt to ascertain their relative ages, unless they had been found vertically above each other. The varying depths of an estuary, its banks of silt and sand, the set of its currents, and the influence of its tides in scouring out alluvium from some parts of its bottom and redepositing it in others, are circumstances which require to be taken into account in all such calculations. Mere coincidence...

Page xlvii - ... find no guidance, will be securely threaded by the clue furnished by the naturalist. All who are competent to express an opinion on the subject are, at present, agreed that the manifold varieties of animal and vegetable form have not either come into existence by chance, nor result from capricious exertions of creative power ; but that they have taken place in a definite order, the statement of which order is what men of science term a natural law.
Page li - What then does an impartial survey of the positively ascertained truths of palaeontology testify in relation to the common doctrines of progressive modification, which suppose that modification to have taken place by a necessary progress from more to less embryonic forms, or from more to less generalized types, within the limits of the period represented by the fossiliferous...
