In the second edition, printed five years after the publication of the first edition, a chapter on allergy has been added; the chapter on vitamins has been rewritten, and additions have been made in those on acidosis, alkalosis and anhydremia. The size has also been decreased by eliminating repetition. As to the subject matter in general, enough can hardly be said. It covers the field of infant nutrition thoroughly and interestingly. This is studied from a physiologic and practical standpoint. The discussion of practical feeding and of the nutritional disturbances is particularly excellent. In consideration of the welter of misinformation that has been published in the last few years, such a sane, practical book is much needed. It should be in every pediatrician's and general practitioner's library.
