FOODS NUTRITION. 999 



Cussed with reference to the high food requirements of cold regions as compared 

 with the tropics. The various factors which make up climatic effect were pointed 

 out and the possibility of modifying it in such ways as by heating moms in cold 

 regions was spoken of. i See also E. S. R., 15, p. 387.) 



The consumption of fat in the Tropics {Jour. Prat., 1904, May 21, p. 332; abs. 

 in Rev. Soc. Sci. Hyg. Aliment, 1 (1904), No. 2, p. 181). — Considerable fat is com- 

 monly observed in the diet of persons living in the tropics. It is pointed out that the 

 increased transpiration and other conditions require a fairly large amount of energy, 

 and that fat furnishes this in a convenient form. 



Carbohydrate cleavage. II, The substance which renders pancreas 

 active, O. Cohnheim (Ztschr. Physiol. Chem., 4- I 1904), No. ,, pp. 401-409, jigs. 2). — 

 The experiments reported have to do with the problem of carbohydrate cleavage in 

 the body with special reference to the presence of glycolytic ferment in muscle. 



Fiber and iron in the food of man, F. W. Robison | Ann. Rpt. Michigan Acad. 

 Sri.,/; ( 1904), /'/'■ 125-127). — The importance of crude fiber and iron in nutrition is 

 spoken of. The author believes that the presence of the larger amounts of these 

 constituents in whole wheat flour is favorable to its use in comparison with the liner 

 grades. 



The pharmacology of sulphur, A. Heffter {Arch. Exper. Path. u. Pharmakol. , 

 51 (1903), p. 175; nl,*. in Zentbl. Physiol, 18 1 1904), No. 21, r . 673).— According to the 

 author the formation of hydrogen sulphid from free sulphur in the intestine is due 

 to the action of proteids present in the mucous membrane. The blood cells possess 

 the same property though the stomach mucous membrane does not, and by the intra- 

 venous injection of finely divided sulphur it is possible to produce hydrogen-sulphid 

 poison. 



The metabolism of sulphur and phosphorus on an abundant diet, K. Born- 

 stein ( Arch. Physiol. [Pfluger], 106 (1904 I, No. J-.', pp. 66-79). — The author was him- 

 self the subject of the experimental work described in which the income and outgo of 

 nitrogen w as studied, as well as the excretion of sulphur an. 1 phosphorus in the urine. 

 In the case of sulphur the total quantity in the urine and the acid and neutral sulphur 

 were determined, and in the case of phosphorus the total amount and the amount 

 occurring in organic form. The author considers that the data furnish an additional 

 proof of his theory that it is possible to induce gains in protein when an excess, 

 especially milk protein, is supplied, provided, of course, the body has not already 

 reached its protein limit. The gain in protein depends upon an increase in the 

 quantity and an improvement in the character of the cell contents. The importance 

 of overfeeding with protein when the body is in poor condition is spoken of. 



The measurement of body temperature, E.Oertmann( Arch. Physiol. [Pfliiger'], 

 105 I 1904 I, No. 7-8, pp. 425, }26). — A maximum thermometer is described, which the 

 author states may be worn in the rectum without inconvenience. 



On the origin and precursors of urinary indican, F. P. Underhill (Amer. 

 Join-. Physiol., 1 .' I 1904), No. 11, />i>. 176-183). — Thegeneral plan of the experiments 

 reported was to feed dogs in the fore and after periods a mixed diet containing 

 lean meat, which was known to produce a large yield of indican and to replace the 

 meat with gelatin in the middle period, it was found that feeding gelatin greatly 

 diminished the amount of urinary indican. "The fact that gelatin will reduce the 

 quantity of indican excreted — that is, causes a diminished formation of putrefactive 

 products— ig not alone of theoretical interest, but may prove of clinical importance 

 in the treatment of certain conditions of the intestine where it is desirable to avoid 

 the products of putrefaction." 



Review of the literature of composition, analysis, and adulteration of foods 

 for the year 1903, A. .1. J. Vandevelde (Separate from Bui. Serv. Surveill. Fabric, el 

 Com. Denrees Aliment., 1904, pp. 101). — This is the fourth annual volume reporting
