This is a thoroughly revised edition of one of the classical teaching textbooks of medicine. The editors have accomplished the seemingly impossible task of including more subject matter, in the form of twenty new treatises, and shortening the text by 8%. This has been accomplished by the complete rewriting of many sections. Diseases have been regrouped according to etiology and the basic physiological, biochemical, and pathological factors discussed. Psychosomatic aspects are not neglected. Therapeutics are conservatively and generally handled. This is a thoroughly satisfactory textbook of medicine, excellent for teaching medical students or as a ready standard reference volume for the physician.
