A subject of the greatest interest to all practitioners of medicine is the use of the various sulfonamide compounds in the treatment of infections. Indeed, no aspect of medicine has attracted wider attention during the past few years. In this edition of Dr. Spink's monograph there is presented in a simple, direct and clear style a summary of sulfonamide therapy which should be read by every student of the subject and every practitioner of medicine who uses these important therapeutic agents. The text shows a sense of critical method which is invaluable to the reader, and many of the case reports which are based on the author's personal experience are illustrated by good charts. Dr. Spink has done a splendid piece of work and the medical profession is indeed fortunate to have such an authoritative and up to date monograph on the sulfonamides available as a guide to treatment.
