IV.—The Most Recent Changes of Level and their Teaching. The Rapid Collapse of Some Districts at the Close of the Mammoth Age

Extract

In some recent papers published in the geological magazine, I have endeavoured to show that at the close of the Mammoth age there was a very considerable dislocation of the earth's crust, and that a consequence of it was the upheaval of some of the highest masses of land on the earth, including the massive mountains of Asia and the American Cordillera. I now propose to show that (as is à priori probable) there was a concurrent collapse or sinking of the ground over large areas, which, as in the corresponding upheaval, was very rapid, if not sudden.
