This manual is attractively written and will hold the attention of the patient. The diagrams are ingenious. The text is sound, sensible and practical. The author cheers the patient by recording a list of patients who took insulin and later were able to discontinue it. Many will differ radically with his interpretation of reactions and will not agree that they are present with a high blood sugar; but that is a comparatively minor point. Sample menus are given for carbohydrate 140 Gm., protein 60 Gm., fat 111 Gm., and evidently this is a diet which the author frequently employs. Any practitioner can recommend this manual to his patient without any misgivings. It is sure to do good.
