"In the beginning, it appears that water covered the whole earth. . . It was the great age of fishes. . . . Upon the land came, first, according to the story of the rocks, a class of animals known as amphibians. Then followed an age in which the predominating animals were gigantic reptiles. . . . During the age of these prehistoric monsters, the earth was yet more fully prepared for higher life."
