weight (about :2,40(» and 2,700 calories for a man weighing 150 lbs.) and not 

 more than 80 to 100 gui. of protein. If, however, muscular work is performed, 

 he believes that the diet should equal that needed in other countries for the per- 

 formance of a like amount of work, and cites instances which show that gen- 

 erous amounts of food are required in the Tropics for the performance of 

 l)h.vsical work and a corresponding maintenance of vigor and physical condition. 

 " A school luncheon, A. L. Benedict {Dictet. and lli/g. Gaz., 23 (I'JOT), No. 

 7, p. .'/O'l). — A school luncheon is described, costing one cent per person, which 

 furnished 8.00 gm. protein, O.OS gm. fat, and 35.11 gm. carbohydrates. 



Prepared and predigested foods, G. LusK {Jour. Amcr. Med. Assoc, .'i'.) 

 (1907), No. 3, pp. 201, 202, 270). — ^A paper, with discussion, in which food re- 

 quirements of the human body are considered and the composition and true 

 value of a number of proprietary foods and food products are discussed. 



Sham feeding e:iperiinents with adults, Helene Kaznelson {Arch. Physiol. 

 \Pfliigcr], J 18 (1907), No. 5-7, pp. 327-.i52, figs. 6). — Some of tlie conclusions 

 whicli were drawn from ex]>erimental investigations witli hospital patients fol- 

 low: Widely different stimulants which affect the organs of taste or smell can 

 induce gastric secretion in the passive stomach or increase a weak secretion if 

 already started. The mechanical act of chewing did not bring about gastric 

 secretion. A fat-cleaving ferment is found in the gastric juice. The acidity of 

 the gastric juice in normal man is relatively constant but the quantity secreted 

 shows the greatest variations. 



On metabolism during- starvation. I. Nitrogenous, ¥,. P. Cathcart {Jour. 

 Physiol., 35 {1907), No. 5-G, pp. 500-510). — Particulars are given regarding the 

 excretion of different urine constituents during a 2 weeks' fast and preliminary 

 and supplementary periods. The smallest nitrogen outi)ut per day, 2.84 gm., 

 was noticed on the third day of a practically nitrogen-free diet, starch and 

 cream, in the i)eriod immediately following the fasting period. 



Experiments on prolonged protein feeding, D. Forsyth {Jour. Phi/siol., 

 35 {1907), No. 5-(j, pp. XL, XLI). — Domestic fowls w^ere kept on a meat diet 

 for periods varying from 11 months to 2 years and remained healthy. An 

 abundant supply of lime was given with the meat. Post-mortem examinations 

 showed no changes in the viscera, the thyroids were not enlarged, the long bones 

 were healthy, and there was no indication of gout in the joints. 



Investigations on the formation of glycogen in the liver, K. (Jruhe (Arch. 

 Physiol. [Pfliiycr], 118 (1907), No. 1-2, pp. 1-29, figs. ^ ) .—According to the 

 investigations reported, the liver can form glucose from the simple sugars, dex- 

 trose, levulose, and galactose, but not from cane sugar, milk sugar, pentosans, 

 carbohydrate-free protein, or active and inactive amino acids. 



The influence upon metabolism of the air pressure noted in automobiling. 

 A. MouNKVRAT (Coinpt. Ix'ctid. Acad. Hci. [I'aris], 1',', (1907), pp. 12'i] . 12'i2;uhs. 

 in Chcni. Zentbl., 78 (1907). II, No. .'i, p. 3//.7). — The air movements noted in 

 rapid automobiling. according to the author's investigations, increase the num- 

 ber of red blood corpuscles in normal and also in some pathological subjects. 

 Urine analyses indicated that metabolism was decidedly increased. 



ANIMAL PEODUCTION. 



Notes on South African food stuffs, H. Ingle (Transvaal Agr. Jour., 5 

 (1907). No. 20, pp. 925-92iS). — In a discussion of horse and mule feeding under 

 local conditions and of the importance of mineral matter in the ration, the 

 author concludes that oat hay or oat hay and mealies (Indian corn) "are not 

 suitable as the exclusive diet of working horses and mules, for two reasons : (1 ) 

 Such a diet is uot rich enough iu nitrogenous matter iu proportion to carbohy-
