Infections endocarditis presents problems of great interest to the student of infections. First there is that much discussed but still unsettled question: Why is the left side involved so much oftener than the right? And then, in the cases that run a more protracted course, the problems of the complicated mechanisms whereby a focus of infection in the middle of the blood stream is permitted to maintain itself for so long a time naturally press forward for some attempt at solution. In connection with these and other phases of infectious endocarditis the results of the investigations of Rosenow1 merit special notice.

In the first place, Rosenow, on the basis of a considerable experience, emphasizes strongly the diagnostic value of blood cultures, especially in the early stages of infectious endocarditis. Blood cultures may serve not only to establish the existence of endocarditis, but also the etiologic nature of the process.
