This textbook, which has provided instruction in the fundamental principles of surgery to many thousands of medical students throughout the world, has been again rather thoroughly revised. Moreover, many changes have been made to adjust the text to American teachings and practice of surgery. Sections dealing with basic sciences, such as bacteriology and hematology, have been entirely rewritten and somewhat shortened. The entire text has been brought up to date, particularly with regard to abdominal surgery, surgery of the nervous system and traumatic surgery. The chapter on war surgery, which the authors mention in the preface, is not contained in the book sent the reviewer. This volume should continue to be a leading textbook for instruction of medical students and an excellent reference book for the general practitioner.
