It is interesting to compare this edition with the one of ten years ago. The space devoted to infections is now considerably smaller, as visible tribute to the effectiveness of the antibiotics. The chapter on shock has likewise shrunk, plasma and the blood bank having diminished the pathologists' supply of material from these sources. Thus the pathologist quickly reflects the trends of modern surgery. Congenital cardiac deformities, inaccessible lesions and obscure tumors of that era all are now within the surgeon's domain. The revisions made in this volume are needed to keep pace with the giant strides of modern medicine. It is heartening to see so many changes where least expected. The author has managed, as usual, to keep abreast of the tide and is maintaining the eminent place in pathology he long since attained.
