This short monograph is an enlarged version of a series of lectures given by the author before several audiences in the Argentine Republic. Although the book is essentially practical, the reader is prepared by an excellent chapter on physiopathology of the circulatory system logically leading to those concerned with pathogenesis and etiologic factors. The remaining chapters are devoted to the clinical symptoms, differential diagnosis, prognosis and treatment. The indication of the different therapeutic means to be used in each case is especially good. The sources of the monograph are largely American, e. g. Cannon, Moon, O'Shaughnessy, but important Argentine contributions are also quoted. The subject is developed with remarkable clarity and conciseness, and the monograph appearing in these days is most timely. It should be read by the general practitioner and carried in the pocket by the military physician.
