This convenient pocket-sized book was prepared by the Committee on Education of the American Diabetic Association. Intended as a guide for physicians, it covers in outline form the commonly accepted procedures of diagnosis and treatment of diabetes mellitus, hypoglycemic reactions, and diabetic coma. The section dealing with the calculation of diabetic diets is particularly instructive. The principle of food exchanges is explained, and a number of sample meal plans are listed. Short lists of references suitable for the physician and for both the patient and the physician have been included. This little manual will undoubtedly live up to its aim, to help the busy medical practitioner give his diabetic patients effective treatment.
