This sixteenth edition of an exceedingly fine textbook of medicine maintains the high standards of the previous editions. This book is intended primarily as a text for medical students and stresses only the major aspects of disease entities. A bibliography at the end of the discussion of each disease is of value to the student who desires more specific information on puzzling problems. Recent advances in methods of treatment are included in this edition, including the use of streptomycin. The new terminology of infectious diseases has replaced the old, and adequate discussion of the revised concepts of clinical entities is carried out whenever indicated. Brevity, which is important in a textbook of medicine, makes this volume of value to the student who is still primarily interested in principles of disease processes.
