858 EXPERIMENT STATION RECORD. 



Zentbl. Physiol., 29 (lUU,). \o. 3. p. /.^?).— Acoordiug to the authors, children, 

 both naturally and artificially fed, were able to utilize tri-calciuni phosphate 

 taken with cod liver oil. 



The etiology of beri-beri with reference to the total phosphorus me- 

 tabolism, li. SciiAUMANN (Arch. Schiffx u. Tropcn Hyg., 14 {1910), Beihefte 

 H. pp. 397, pis. 12, figs. 2). — In this hook the work of others is extensively 

 reviewed and summarized, and the author presents a larsre amount of original 

 experimental data. 



Various theories regarding \\\c^ etiology of the disease are briefly presente<l 

 and discus.sed. 



Etiology of beri-beri, II, II. Schaumann {Arch. Schiffs u. Tropen Hyg., 18 

 {191Jf), Beihefte 6, pp. 7-25S). — Continuing the above work, the author reviews 

 a large number of metabolism experiments with laboratory animals (rabbits 

 .ind pigeons). 



On feeding preparations of maize and rice treated in different ways, it was 

 found that the nitrogen balance iu beri-beri was negative, indicating a lo.ss of 

 body protein. The total phosphorus baliince was negative, and the phosphorus 

 content of the urine was below iho normal value. 



A study of "antineuritic " substances of natural occurrence led to the con- 

 clusion that beer yeast was the most active and rice polishings the next active 

 in preventing the disease. Moreover, the antineuritic property seemed to vary 

 according to the method of preparation. 



It is the opinion of the author that the antineuritic substance occurs in foods 

 in very stable compounds and may pass directly into the blood stream of some 

 animals without simplification. 



A review of the literature of phosphorus compounds in animal me- 

 tabolism, E. B. Forbes and M. Helen Keith {Ohio Sta. Tech. Bui. 5 {1914), PP- 

 748). — This extensive digest of the literature of phosphorus metabolism has 

 been noted editorially (E. S. R., 32, p. 601). 



The value of the calcium balance as an index of calcium metabolism, N. 

 ScHOOEL (Pharin. Weekbl., 51 {1914), A^o. 39, pp. 1216-1219).— \ digestion ex- 

 periment is described in which the amounts of calcium in the food ingested and 

 in the body excretions was determined. In the experimental period of five 

 days the amount of calcium ingested was 10.14 gm. and the amount excreted in 

 the urine and feces 10.11 gm. 



Analytical methods and experimental technique are described in detail. 



The influence of the melting point of nonemulsified fats on the rate of 

 leaving the stomach, A. von Fejer {Biochetn. Ztschr., 53 {1913), No. 1-2, pp. 

 168-178, fig. 1; abs. in Ze^itbl. Phimol.. 29 {1914), Ko. 2, p. 82).— Various fats 

 used in feeding experiments were at intervals removed from the stomach and 

 analyzed to determine the amount which had not passeil into the intestine. It 

 was found that the higher the melting point and the greater the viscosity the 

 longer the fats remained in the stomach. The nonemulsified fats left the 

 stomach more slowly than the fat emulsions. 



.Contributions to the physiology of the stomach. — XXI. The supposed 

 action of the bitter tonics on the secretion of gastric juice in man and dog, 

 A. J. Carlson et al. {Jour. Amer. Med. Assoc, 64 {1915). No. 1, pp. 15-17). — ■ 

 Experiments carried out with men and dogs indicated that bitter tonics acting 

 in either the moufh or stomach have no influence on the secretion of gastric 

 juice, and, as a result of this, on gastric digestion. 



The ferments of the pancreas. — III, The properties of trypsin, trypsinogen. 

 and enterokinase, J. Mellanby and V. J. Woolley {Jour. Physiol., 47 {1913), 

 No. 4-5, PP- 339-360). — In continuation of experiments previously reviewed 

 (E. S. R.. 29. p. 662). the authors report considerable information on the prop-
