This volume in its second edition is complete and concise and beautifully illustrated. It contains only the rich meat of physical diagnosis and differential diagnosis and there is little wasted space in nonessentials. The case histories, which are few, are well presented, are illustrative and are not needlessly lengthened. The author has succeeded admirably in covering a large and difficult subject. References to laboratory methods and recent aids to diagnosis are numerous. Illustrations, diagrams, roentgenograms, colored plates of eyegrounds and skin reactions, and electrocardiographic tracings are numerous and well selected.
