[Examination of food and drugs and inspection work for November], 

 H. E. Barnard (Mo. Bui. Ind. Bel. Health, 12 {1909), No. 11, pp. 157-160).— 

 Brief statements are made regarding tlie examination of a number of samples 

 of drugs, beverages, and food products, and tbe inspection of grocery stores, 

 restaurants, and similar places of business. 



Text-book of human physiology, N. Zuntz and A. Loewy (Lchrhuch der 

 PhyfiioJogiv dcs Mcnschcn. Lcipsic, 1909, pp. XII+763, pis. 2, figs. 306). — The 

 various chapters in this comprehensive text-book of physiology are contributed 

 by a number of different authors. 



Of special interest to students of nutrition are those on General Physiology, 

 by M. Verworn ; Chemical Composition of the Animal Body, by J. Miiller; Gen- 

 eral Physiology of JNIuscles and Nerves, by O. Weiss; Physiology of the Central 

 Nervous System, by S. Exner ; Functions of the Peripheral Nerve System, by 

 A. Kreidl ; Mechanics of Body Motion, by R. du Bois-Heymond ; The Chemistry 

 of Bespiration, by J. E. Johansson ; The Mechanics and Innervation of Respira- 

 tion, by R. du Bois-Reymond ; Partial Digestion, by Ellenberger and Scheunert ; 

 Respiration and Assimilation, by Spiro; Urine and Urine Formation, by 

 Cohnbeim ; Excretion Through the Skin, by R. Metzner ; Internal Secretions 

 and Their Chemical Relation to Body Processes, by R. Metzner; Metabolism of 

 Matter and Energy, by N. Zuntz ; and Reproduction and Growth, by A. Loewy. 



In the section on internal secretions the relation of the thyroid and para- 

 thyroid secretions, the secretions of the hypophysis, the suprarenal capsule, 

 and the thynms, pancreas, and spleen are discussed with special reference to the 

 modern theories of the chemical regulation of body processes. 



In the chapter on the metabolism of matter and energy. Professor Zuntz 

 discusses general problems, summarizes the results of his own extensive studies 

 of methods and the results of his experimental work, and devotes attention to 

 respiration experiments, respiration calorimeter experiments, and those in 

 which the respiratory quotient is determined. Nitrogen metabolism, over- 

 feeding, the importance of mineral constituents, the selection of food imder 

 different conditions, the protein requirements of man in different circumstances, 

 the factors which influence protein requirements, nitrogen metabolism in the 

 body during growth and repair, condiments in relation to nutrition, and similar 

 questions are also considered. 



With refei-ence to the question of dietary standards he concludes that since 

 the relation between resistance to different infectious diseases and the protein 

 content of the diet is not known, it is not desirable at the present time to 

 diminish generally the amount of protein in the diet below SO gm. per day for 

 an adult man. It is possible to obtain such a quantity of protein entirely from 

 vegetable foods if they are wisely selected, but he considers it much easier and 

 more agreeable to use animal foods in reasonable quantit.v in combination with 

 the cereals and vegetables which are less rich in nitrogen in order that the 

 needed amount of nitrogen and fat may be secured. 



In their introduction the editors state that the volume as a whole is designed 

 especially for the use of advanced students and physicians. 



Nutrition diseases — a text-book for physicians and students, F. Umbee 

 {Lchvhuch der Ernahrung und der Btoffwechselkranikjieiten fur Arzte und 

 mudicrcnde. Berlin and Vienna, 1909, pp. VIII+^02, pis. 10, figs. 19). — In addi- 

 tion to chapters on corpulence, diabetes, gout, the less common disease of inter- 

 mediary protein cleavage, and similar topics, the author discusses food and 

 nutrients in general, food cures in the case of the insufficiently nourished, and 

 artificial feeding. Though the last mentioned chapters are perhaps of special 

 interest to students of nutrition, a large amount of data of general interest 

 will be found in the sections which deal with pathological questions, particu-
