Abstract
THE correlation of the successive occupation of Europe by various races of mankind with the successive events of the Glacial period has been greatly facilitated by the successful investigations of Prof. Albrecht Penck into the Quaternary history of the eastern Alps. Four well-defined terraces can be traced up the valleys of this region, each of them taking its origin in a terminal moraine. They represent the deposits of rivers issuing from the front of the ice during a glacial episode. Between the terraces the valleys show evidence of deepening by erosion during periods which correspond to genial intervals, the last of which, in order of time, is represented by the breccia of Hotting, when the temperature at Innsbruck, as shown by the included leaves and bracts of Rhododendron ponticum, was 3° C. higher than the average at the present day.
