This leading British composite textbook of the practice of medicine is comprehensive, containing almost 2,000 pages printed on thin paper. The first edition appeared in September 1922, and there were five printings. The second edition was published in 1926 with two printings, and the third edition in 1929 with three printings. The present edition has been thoroughly revised and brought up to date, containing new articles on many subjects. The list of contributors to the volume includes twenty-seven British physicians whose names are notable in British medical periodical literature. Thus the vitamins are discussed by Plimmer, syphilis by Harrison, and the gastro-intestinal diseases by Hutchison and Hurst. The volume affords an adequate reflection of British methods of practice.
