Similar testimony is borne by the occurrence of the implements and remains of Palaeocosmic men in gravels and in diluvial clays in caverns, and by the changes of level and deep erosions of valleys that are referable to the close of the Palaeocosmic age. The most probable agencies in this revolution were subsidences of the land, ac- companied with climatal changes; but the precise nature and extent of these is still unknown; and the prevalent tendency on the part of geologists to stretch the doctrine of uniformity,.

It would be premature to correlate what is yet knOwn of the Palaeocosmic age with historical periods; but the tendency of the facts accumulated is, I think, toward the identification of the Palseocosmic men with the Antediluvians; and their Neo- cosmic successors, whether of the reindeer age, of the Danish.
