This is a careful study or, rather, a review of menstruation and its anomalies, in connection with general and local physiology and pathology. The subject matter was furnished by the lectures on clinical gynecology given by the author to his Bahia pupils since 1911. There is therefore little original material. It fulfils, however, its purpose of bringing together information of value to students, and even physicians, on a function—or rather, if we may believe Pinard, an accident—the importance and bearing of which are often neglected to the patient's detriment. The book is well printed in large type. There are no illustrations and no index.
