Abstract
THIS book is good in places. Prof. Tammann discusses geochemistry. His article contains a needed warning against the too ready acceptance of the hypothesis of a sulphide shell of considerable thickness. On the other hand, he asserts that there is a critical pressure, above which the melting point decreases with pressure, and makes no mention of Bridgman's criticism of this hypothesis. G. Kirsch deals with radioactivity, age determinations, and heat supply, on the whole well, but gives on p. 51 a misleadingly incomplete statement of the nature of Jeffreys's objections to the theory of periodic melting. Kossmat's article on tectonics is useful and critical, though too short for the subject, and there is a shortage of quantitative data on the topics discussed.
