The first edition of this manual appeared in 1928. The Archives of Internal Medicine (42:610 [Oct.] 1928) and the Journal of the American Medical Association (91:1928 [Oct. 20] 1928) contained reviews of it, both reviews speaking well of the book. The second edition is a few pages longer than the first and has a few more illustrations. The manual continues to be an intelligent booklet, useful for both diabetic patients and practitioners or students who wish to brush up on practical diabetic therapy. Once again it is pleasant to notice that the author refers to diabetic manuals already in existence as reading matter recommendable to patients.
