The crust of the earth is a vast museum; but the natural collections have been made only at intervals of time immensely remote.

In the sixth chapter I enumerated the chief objections which might be justly urged against the views maintained in this volume. One, namely the distinctness of specific forms, and their not being blended together by innumerable transitional links, is a very obvious difficulty.
