This book offers a modern basic survey of the history, the theory and the conditions suitable for hydrogymnastics. It includes also four valuable chapters on the use of corrective aquatics, which are especially timely. Practical suggestions on the construction of physical therapeutic pools and their physical equipment as well as administration and departmental arrangement are included. Dr. Lowman successfully employs underwater exercise in certain postoperative cases, in cases of arthritis, infections and open wounds, fractures and poliomyelitis and in spastic patients. The book will be found instructive by all who deal either directly or indirectly with specific problems of posture or health.
