This translation of Glandular Physiology and Therapy is identical with the American edition except for the section by Zondek on the chromatophorotropic principle of the pituitary, which has been revised and considerably enlarged. The translators, Drs. Adolf Nichtenhauser and Kurt Stern of Vienna, and the publishers are to be congratulated on the faithful rendition into German. The number of pages has been reduced one fifth by use of a larger page. Typography, illustrations and binding are all excellent. This edition of the symposium by renowned endocrinologists, which has already received wide acclaim in the English version, should be of great value to German-speaking physicians.
