In this book, a detailed application of anatomy and physiology to the problems of posture and exercise for patients is discussed. The author has considered these problems from both viewpoints, namely that of the patient in danger of weakness, deformities, and bedsores and that of the nurse confronted with the equally real dangers of disabling overstrain. The illustrations, which at first strike the reader as unconventional, are soon appreciated as remarkably illuminating; they make the book extremely valuable. It is hoped that in some future edition the author will break further with convention by getting rid of the illogical adjectives "concentric" and "accentric" as applied to certain kinds of muscular activity (page 9). This book should be available in the library of every school of medicine and nursing.
