Professor von Hoesslin presents in this volume the various nontuberculous diseases of the respiratory system. A good discussion is presented on the etiology of acute and chronic bronchitis, as well as the treatment of these conditions. Considerable space is given to the diagnosis of bronchial asthma, its cause in each case being sought. The types of bronchiectasis are presented with reference to etiology. In treatment, collapse therapy is given consideration and attention is called to the fact that it is not always possible to bring the disease under control in this manner. The use of neoarsphenamine is discussed. Tumors of the lung and pulmonary syphilis are emphasized. Throughout the book, cases are cited to illustrate various points in diagnosis and treatment. There are no illustrations and no bibliography.
