This helpful little volume will be appreciated by the general practitioner who is confused and has difficulty with the intricate and complex ramifications of endocrine relationships. As with the preceding editions, it is simply written but contains the essentials necessary to the sound practice of endocrinology. This latest edition has been polished and been treated to eliminate some of the minor ambiguities present in the earlier ones. The reviewer has fault with only two sections of this volume: the scant attention to the psychologic factors in the development and treatment of overweight and the lack of a systematic discussion of the ovarian dysfunctions. In regard to the latter, most physicians would be appreciative if this chapter contained headings of the various ovarian dysfunctions and their specific treatment rather than a more or less generalized discussion of these problems. Otherwise, this book is to be commended for its value to practitioners.
