This is a compact, accurate and useful little monograph on methods of basal metabolic studies for clinical purposes. While the German physiologists, especially Voit and Rubner, were the leaders in establishing the laws of nutrition and metabolism, the practical application of these principles in the clinics was essentially perfected and applied in the United States, and there are several monographs in English dealing with this subject. The present volume, therefore, presents to English readers nothing essentially new on the subject, except in the way of a model of compact and accurate presentation. Various European apparatus are described that are not in general use in this country, but these apparatus do not appear to have a great advantage over those in common use in this country. The appendix contains the necessary tables and charts for rapid calculations.
