Dr. Singer is the most eminent of the British leaders in the history of medicine. His contributions to the subject, particularly of Greek thought and its influence on medicine, have been recognized throughout the world. In this book, which is provided for both a medical and a popular audience, he gives a brief survey of the origin of modern scientific medicine, particularly from the Greeks, but he does not neglect the contributions from other sources. He lightens his work by anecdote and example and by an extraordinary number of excellent illustrations. The book should serve particularly well as a textbook for short courses on medical history if a textbook is desirable. As a reference book it is not, of course, in the same class as the "History of Medicine," by Garrison. Dr. Singer's style is readable, and his diction admirable.
