Abstract
THE rate of denudation must have varied very considerably during the earth's history, for it depends on both the height of the land and on the meteorological conditions, both of which have certainly changed very much from time to time. The consistency of the various geological methods among themselves does not prove that there has been no change in the rate of denudation, for such a change would affect them all in the same ratio.
