The seventh edition of this well known work is supplemented by the addition of a co-author and a number of contributors. Entirely new sections have been added on chemotherapy, anesthetics and the treatment of some diseases. Many sections have been completely rewritten. There are also references to new drugs such as dilantin and heparin. The work manifests the special interests of Dr. Clendening in its historical and literary references. The section on psychoanalysis is somewhat elementary and perhaps many psychoanalysts would call it distorted. Indeed, it might be questionable whether or not such an unsatisfactory portion of the book might not better be eliminated. Elsewhere the volume is marked throughout by good common sense and will be found most helpful to every practicing physician.
