The Principles and Practice of Medicine.

The fourteenth edition of Osler's Principles and Practice of Medicine, edited by Henry A. Christian, justly commemorates fifty years of a living, vital textbook. In preparing this book the editor, losing none of the charm of the original text so brilliantly conceived and presented by Dr. Osier, has added to the preceding editions to a degree that justifies this semicentennial edition. The general method of presenting the text remains essentially the same, although any one familiar with the previous editions will probably find this one as readable and delightful. Through the careful and thoughtful editorship of a thoroughly trained clinician recent advances in diagnosis and therapy have been added.

A few features deserving especial commendation reveal both the teacher and the practitioner in the editor. He introduces the text by a brief and thought-provoking discussion of psychosomatic medicine and follows with a chapter on functional diseases of the nervous system.
