This elaborate and comprehensive book on dietetics was reviewed in the Archives several years ago (40:177 [July] 1937). The criticisms then expressed still hold to some extent, although the work contains a vast amount of useful information. Since Dr. Bridges' death, a group of collaborators have prepared this fourth edition and have done their work extremely well. They have vastly improved the book, especially the discussions of diet with reference to special diseases. The immense amount of tabular data on foods remains invaluable for reference.
