Diseases of Nutrition and Infant Feeding.

The first part of this book contains chapters on the physiology of digestion, and the metabolism of the various food elements—the fundamentals, the proper foundation and introduction to the main part of the work, which is a clinical and practical discussion of infant feeding. The laboratory worker will find in the early chapters a résumé of the latest views on the metabolism of early life with full reference to the work which has been done in this direction. That work has been carefully sifted, and critically analyzed. It is refreshing to come across such a sentence as this: "It seems wise to summarize what wethinkwe know about the digestion and absorption of fat." This candor and frank acknowledgment of our limitations is characteristic of the book: repeatedly one reads, "but this is not proved," following the statement or description of a well-established clinical observation.
