7. It can not fail to be observed that we have in these verses two different arrangements of the animals created, neither corresponding exactly with what modern science teaches us to regard as the true grouping of the animal kingdom, according to its affinities. The order in the first enumeration should, from the analogy of the chapter, indicate that of successive creation. The order of the second list may, perhaps, be that of the relative importance of the animals, as it appeared to the writer. Or there may have been a twofold division of the period--the earlier commencing with the creation of the humbler invertebrates, the later characterized by the great reptiles--which is the actual state of the case as disclosed by geology. 8. The Creator recognizes the introduction of sentient existence and volition by _blessing_ this new work of his hands, and inviting the swarms of the newly peopled world to enjoy that happiness for which they were fitted, and to increase and fill the earth, inaugurating thus a new power destined to still higher developments. When we inquire what information geology affords respecting the period under consideration, the answer may be full and explicit. Geological discovery has carried us back to an epoch corresponding with the beginning of this day, and has disclosed a long and varied series of living beings, extending from this early period up to the introduction of the higher races of animals. To enter on the geological details of these changes, and on descriptions of the creatures which succeeded each other on the earth, would swell this volume into a treatise on palaeontology, and would be quite unnecessary, as so many excellent popular works on this subject already exist. I shall, therefore, confine myself to a few general statements, and to marking the points in which Scripture and geology coincide in their respective histories of this long period, which appears to include the whole of the Palaeozoic and Mesozoic epochs of geology, with their grand and varied succession of rock formations and living beings.
