Abstract
IN the sixth volume of Fortschritte der naturwissen-schaftlichen Forschung, Prof. VV Halbfass reviews the recent work on the topography, hydrography, and geology of the lakes ot Asia, Africa, America, and Australia. Dr. A. Rühl, in his paper on a new method in geomorphology, pleads for the application of the deductive method to the borderland between topographical geology and geography. The exposition of the peneplain theory ot Prof. Davis, as well as of other points bearing on normal marine, glacial, and arid cycles, is illustrated by photographs and diagrams. The results of recent researches in radio-activity, particularly on uranium, thorium, and actinium, form the subject of a review by Prof. Otto Hahn and Dr. L. Meitner.
