of the fossil world, than they do among the living members of the animal kingdom.” Professor Owen writes—“No reptile now exists which combines a complicated and thecodont dentition with limbs so proportionally large and strong, having such well-developed marrow-bones, and sustaining the weight of the trunk by _sychondrosis_ or _anchylosis_ to so long and complicated a sacrum, as in the order _Dinosauria_. The Megalosaurus and Iguanodons, rejoicing in these undeniably most perfect modifications of the reptilian type, attained the greatest bulk, and must have played the most conspicuous parts, in their respective characters as devourers of animals and feeders upon vegetables, that this earth has ever witnessed in oviparous and cold-blooded creatures. They were as superior in organization and in bulk to the crocodiles that preceded them as to those which came after them.” 6. We close our enumeration of these fossils by simply stating, that the CROCODILIANS also flourished at this period. The living species are twelve in number, all remarkable for the size of their mouth, and their exuberant abundance of teeth. The extinct species were nearly as numerous, but all more allied to the gavials of New Holland than to the other members of the family. They seem chiefly to have subsisted on fishes, while their modern congeners are furnished with powers which enable them to prey upon mammalia and other quadrupeds. When Hobbes, the philosopher of Malmesbury—the old haunt of all these monsters—adopted the title “leviathan” for his political and anti-Christian views, he did it more in derision of the name than from any belief that such things as the term represents had ever or could ever have existed “in rerum natura.” Persons, even now, to whom the subject is presented for the first time, will turn with aversion from its details under the influence of the very opposite feelings from those of the infidel metaphysician. The evidence of facts however, will yield neither to prejudices nor to theories. And, while we dream not of representing the patriarch of Uz as drawing his inferences from geology, still his mind was alive to convictions of the grandeur and diversity of the works of creation—to a sense of his own ignorance—and filled at the same time with awe and veneration at the unsearchable wisdom of the ways of Providence. “STAND STILL AND CONSIDER THE WONDROUS WORKS OF GOD. HAST THOU ENTERED INTO THE SPRINGS OF THE SEA? HAST THOU PERCEIVED THE BREADTH OF THE EARTH? DECLARE, IF THOU KNOWEST IT ALL.” CHAPTER IV. THE WEALDEN FORMATION.
