A chapter on gout, one on focal sepsis and details of new methods of treatment have been added to this edition. The reviewer, however, is unable to share the enthusiasm expressed by others for the book. It is notably lacking in that critical discrimination between modes of treatment which is so highly desirable at the present time. A considerable number of proprietary remedies is recommended, some of them fortunately practically unknown in this country, including Kia-uma, Amysal, Balmosa, Aspriodine, Alasil and Kalmopyrin. A chapter is devoted to colonic therapy, with no new evidence added as to its efficacy, if any. There is also a chapter on osteopathy and "nature cures" in which, as in previous editions, osteopathy is far too favorably considered. The author would do well to consult the report of the select committee of the house of lords on the Osteopaths Bill in 1935 in his own country.
