This is a thorough description of the performance of the muscles used in breathing. Included are history of previous concepts of the role played by various muscle groups, the anatomy and mechanical actions of respiratory structures, and electromyographic data obtained during respiration. These are correlated by the author to present a concept of the mechanics of breathing. The muscle groups so studied include those of the thorax, neck, back, abdomen, and larynx. They are studied both in quiet respiration and in varying degrees of hyperventilation. Most studies were done on normal patients, but some data are included on emphysematous subjects. A brief discussion of control and coordination of respiratory muscles and the work of breathing is included. There is also a discussion of the pressurevolume diagram of the thorax.

The material is presented in a concise manner and in terminology which is readily understood. Graphs and actual recordings are used
