Die Eiszeit und der vorgeschichtliche Mensch

Abstract

PROF. STEINMANN, with evident pleasure, contributes this work on the Ice age to a popular series issued by the firm of Teubner. The black letter type shows the audience for which it is intended, and it will admirably carry on the campaign of the German geologists fora more general understanding of the earth. After indicating that an oceanic and moderately cold climate, rather than a continentally extreme one, will provide the conditions for an Ice age, the author appeals to the scenic features of a country where glaciers have worked their way. He supports the view of the over-deepening of valleys by glaciers, and clearly points out the effects of differences of pressure in different regions of a complex ice-stream. Prof. Heim would doubtless remark that the U-form indicated in the picture of the Lauterbrunnen valley (p. 21) is obviously due to taluses; but little fault can be found with the author's account of the variety of characteristic outlines traceable in all regions that have undergone an Ice age.
