This monograph is timely in that it expounds in a lucid and interesting style the physiologic evidence and theory bearing on a new field of physiology which has been intensively cultivated during the last decade. This new field pertains to the concept that chemical mediators are concerned in the transmission of impulses from nerves to the muscular and glandular cells they innervate. The organization of functional activity of the autonomic system, as far as the evidence for the chemical mediation of autonomic impulses is concerned, is presented in a simple, concise and well organized manner.
