A Plea for the Experimental Investigation of some Geological Problems

Abstract

THE subject of terrestrial physics involves the study of such a large number of phenomena that it is quite comprehensible that any one investigator must devote himself to only one or two branches of it at the most. The consequence of this is that from time to time some section of this extensive field of research is for a period neglected. Such is really the present state of experimental geology, and especially that branch relating to movements of the earth's surface.
