An endeavor is made in this paper to analyze a large series of cases of acute endocarditis treated in hospital wards, not so much for the purpose of imparting new information on a subject already much discussed, but to give briefly the etiology, symptoms, physical findings, treatment and immediate results of the treatment as they were recorded in these 250 cases. Only cases of acute endocarditis are included in this series.
