An excellent and interesting discussion of hypertension is to be found in this monograph. The facts are stated clearly, concisely and accurately. Speculation is reduced to the minimum. The important references are quoted in extenso, so that it is scarcely necessary to go back to the sources. Symptomatology is skilfully delineated with the help of case histories. The chapter on the clinical study of hypertension may well be read over and over again. The author's emphasis on the study of the eyegrounds as the first approach after a careful history and general physical examination indicates his thorough familiarity with hypertension. A complete schema for the clinical study of patients with hypertension is given at the end of this chapter. Prognosis and treatment are discussed along conservative lines. This is an ideal book for medical students of the more intelligent type and for general practitioners who are still curious about disease.
