This monograph deals comprehensively with a subject of somewhat limited interest to the medical profession in general. The chapter on the anatomy of the bronchial tree and lung segments is excellent, and the authors present a well merited plea for universal adoption of a standard system of nomenclature for this region of the body. Chapters on anesthesia for the procedure of lung mapping, roentgen anatomy, interpretation of the bronchogram, pathological bronchograms and the technic of bronchography as employed in Groningen University are among the principal chapters. The book is profusely well illustrated. A number of typographic errors detract slightly from an otherwise admirable work. The chief interest in this book will doubtless be found among bronchologists, thoracic surgeons and roentgenologists.
