The authors have grasped the modern trend in teaching tuberculosis in this work, which they describe in the preface as a handbook. The pages are packed with practical instructions. The subject matter is presented in such an interesting manner as to avoid dry repetition and to stimulate interest in diseases of the chest. Here, according to the preface, "the practitioner may obtain an outline of present day therapeutic measures which will enable him to advise and reassure." Emphasis is placed on the fundamental conceptions that pulmonary tuberculosis is a generalized disease which becomes localized in the lungs and that treatment must be directed at the tuberculosis patient, not just the tuberculous lung. The fifteen chapters with numerous illustrations, mostly reproductions of significant x-ray films, follow the usual routine of presentation of this subject—history, bacteriology, pathology, epidemiology, symptomatology, examination, radiology, differential diagnosis, prognosis, treatment, after-care and tuberculosis as a national problem.
