THE ENDOCRINES IN OBSTETRICS AND GYN/E- COLOGY.- ?By Raphael Kurzrok, M.D., Ph.D. 1937. Bailliere, Tindall and Cox, London. Pp. \vi plus 488. Illustrated. Price, 34s.

In these days of rapid advance of practical medicine much attention is being given to the study of different diseases, more particularly the problems of obstetrics and gynaecology from the point of view of internal secretions, and many a dark corner in the field of clinical diagnosis has been illuminated by the application of the results of investigation into the functions of the endocrine glands. It is no wonder, therefore, that a

practising physician should be considered as being not up to date if he lacks knowledge of this most important branch of physiology. We welcome the publication of this book which deals

with the entire field of organotherapy, more particularly in its relation to obstetrics and gyntecology in a very practical and thorough manner. The important clinical observations and deductions made in the present volume are the results of the author's laborious and intensive study and research work extending over a period of ten years and should prove very valuable not only to obstetricians and gynecologists but to internists and general practitioners as well. The book gives a fairly exhaustive account of the

scientific foundation on which our present knowledge of endocrinology is built up. The addition of a biblio-

graphy at the end of every chapter is very welcome because it serves as a guide to those who wish to

amplify their knowledge on the subject. We have no hesitation in saying that the book is a valuable contri- bution to our knowledge and should prove to be a

standard work of reference on the subject. J. P. B.
