Abstract
TAKING as his basis Dr. Paul Reibisch's “Ein Gestaltungsprinzip der Erde” (1901), supplemented by Mr. D. Kreichgauer's “Die Aquatorfrage in der Geologic” (1902), the author of the curious volume before us discusses the effects which would, in his opinion, be produced on the animal life of the globe by secular changes in the direction of the polar axis. Mr. Kreichgauer,; it seems, is of opinion that in the course of geological time the two poles have actually changed places, and also that during such oscillations huge “wobbles.” or waves have been produced in the earth's crust in the intervening latitudes. These “wobbles,” if we understand him rightly, the author believes have produced marked effects on the; distribution of animal life, having, so to speak, “shaken” the various groups into particular positions. The distribution of all the chief groups is discussed according to the new theory, and in many cases illustrated by maps.
