The review of the tenth edition of this book (The Journal, Dec. 12, 1914) took up four lines. At that time it seemed unnecessary to review at length a book so well known. The present edition, according to Dr. Wood, who revised it, is modified but little. Fundamental conceptions of pathology have not changed much, and there have been few contributions to morphologic pathology. The new edition does contain new material, however, on the reticuloendothelial system, on infectious diseases, on lung abscess and on jaundice. New references also have been added. Dr. Wood has selected for inclusion in the work only a little of the vast material in physiologic and chemical pathology, most of which as yet has not been digested and correlated.
