This is the first section of what promises to be a complete treatise on the pathology and treatment of the diseases of the larynx, trachea and bronchial system, and it deals with these subjects in a beautiful manner. In the first chapter, the anatomy of the larynx, trachea and bronchial tubes is discussed, followed by the second chapter on the physiology of the larynx and airways. The third chapter deals with the various methods of indirect and direct examination (endoscopy), with much attention to the proper instrumentation. The fourth chapter presents the pathology of the upper air passages, including anemia, acute and chronic catarrhal inflammation of the laryngeal, tracheal and faucial mucosa, laryngeal edema, acute laryngitis and perichondritis. There is a good discussion of some of the acute infectious diseases which involve the larynx and the air passages, including such diseases as scarlatina, measles, smallpox and diphtheria.
