THE report of the twenty-fourth meeting of German geographers held at Danzig on May 26–28, 1931, has been published as a volume (Verhandlungen und wissenschaftliche Abhandlungen des 24 Deutschen Geographentages, Breslau), which contains, in addition to the proceedings of the conference, a number of valuable papers. These cover a wide range of topics, but perhaps the most striking is a series on Baltic geography, including a paper by Prof. G. Braun on the oscillations of level of north-western Europe and the development of the Baltic from glacial times. A tabulated chronology of changes in the area makes an interesting study. Prof. B. Schulz writes on the waters of the Baltic, and Dr. W. Quade contributes a long study on the evolution of the port of Danzig in relation to the changes in the mouths of the Vistula. This paper is illustrated by a number of old charts.
