In preparing the tenth edition of this classic practice of medicine, the type has been completely reset. Dr. McCrae points out that constant effort has been made to retain the features characteristic of Osler. The additions have been carefully chosen with a view to permanence rather than to strict up-to-dateness by the inclusion of unestablished views. Obviously, however, recent work on scarlet fever, tularemia, hypertension and many unusual disturbances of the blood and blood-forming organs have had to be included. The new type is clean and easily read. The editor has been careful to use the best established nomenclature. This book continues to maintain its supremacy among textbooks on the practice of medicine.
