Orthopedic Surgery.

Since the publication of the first edition of this book, five years ago, the junior editor, Dr. Robert W. Lovett, had died. Dr. Nathaniel Allison and Dr. Frank R. Ober, former associates of Dr. Lovett, were assigned to the American editorship. Comparison with the previous edition gives evidence of considerable revision and the addition of much new material. In fact, several chapters seem to have been rewritten to include all the new facts that have been presented by various writers on the particular subject under discussion. Thus the chapters on diseases of tendons, muscles and fascia, peripheral nerve lesions, pyogenic conditions of bone, vascular lesions of the extremities and amputations and artificial limbs are extremely valuable additions. But one cannot help but wonder just what the boundaries of orthopedic surgery are: certainly not those assigned originally when special recognition was given to orthopedic surgery. Other chapters have been enlarged. Notable
