These volumes have already been widely acclaimed—and justly so—in general medical literature. They are a survey of wide scope and a valuable account of problems of medical research today. The first volume examines the role of the basic sciences in medicine, current trends of research, seen properly against the background of our social matrix. The second volume deals with unsolved clinical problems, such as metabolism, cancer, infertility, arteriosclerosis, hypertension, the rheumatic syndrome, tuberculosis, virus diseases, alcoholism, and schizophrenia, in that order.
