Abstract
I HAVE long felt convinced that geologists are being misled in reference to former glacial epochs by failing to give due thought to a consideration referred to on former occasions,1 viz. that when the present surface of the globe has been disintegrated, washed into the sea, and transformed into rock, there will undoubtedly then be about as little evidence that there had been glacial epoch during post-Tertiary times as there is at present that there was one during Miocene, Eocene, Permian, and other periods.
