This is a bulky volume of 1024 pages, containing 82 lectures on the diseases of the inner lining of the gastrointestinal canal. There is no discussion of the diseases of the pancreas or of the liver. There is no author's index and the style is rather prolix. Frequently material previously published in articles in medical journals is introduced and there is, on the whole, good room and good reason for condensation. There has been given entirely too little attention in this book to the recent work of Pawlow and others on the various digestive ferments. Nevertheless the general practitioner will find much in these pages that will help him to care for chronic dyspeptics and nervous invalids with gastrointestinal affections. The author lays special stress on treatment.
