Principles and Practice of Rehabilitation

volume contains the manuscripts given at those meetings, although in a few instances only an abstract of the originally presented paper is given. The value of the volume is also enhanced by the printing of the discussion which occurred after various speakers had concluded their remarks. The volume is divided into two parts, one entitled "Contributions from the Fundamental Sciences," and the other called "Clinical Aspects." The chapters, each representing an individual presentation, are noteworthy for theiri authoritativeness and for the thoroughness with which various topics have been covered. The completeness of the book is indicated by the wide scope of the chapter titles and by the fact that an outstanding individual has covered each subject. The chapters, and their authors, are: Contributions of Physiological Investigations, G. R. Cowgill; Relationship of Enzymes to Deficiency, C. A. Elvehjem; The Problem of Nutritional Deficiencies, G. R. Minot; The Role of the Vitamins in Brain Metabolism, H. E. Himwich; The Thiamin Content of Human Tissue, J. W. Ferrebee et al.; Pathology of Vitamin B Group Deficiencies, H. M. Zimmerman; Vitamin A and the Nervous System, S. B. Wolbach and 0. A. Bessey; Effects of Vitamin E Deprivation in Various Laboratory Animals, A. M. Pappenheimer; Symptoms and Signs of Thiamine Deficiency, R. M. Wilder; The Mental and Neurological Aspects of Vitamin B Complex Deficiency, W. H. Sebrell; Emotional Disturbances in Persons with Pellagra, Beriberi, and Associated Deficiency States, T. D. Spies et al.; Multiple Neuritis, Differentiation of Nutritional Polyneuritis from Other Multiple Neuritides, M. B. Strauss; Spectroscopy as Applied to the Study of Phenylpyruvic Oligophrenia, K. Dobriner et al.; Pernicious Anemia and Allied Disorders, W. B. Castle; Psychiatric Syndromes Caused by Nutritional Deficiency, K. M. Bowman and H. XVortis; The Prevention of Nutritive Failure and its Cure, J. S. McLester. Practically every chapter represents a rather complete and authoritative review, and the book therefore takes its place as a valuable monograph relating to many aspects of modern nutrition, with special emphasis on the physiological and clinical aspects of the nervous system. It is a well-written, well-presented, and valuable book. -ABRAHAM WHITE.
