ANIMAL PRODUCTION. 167 



The phosphorus content of the animal organism, W. Heubnee (Arch. Expt. 

 Path. PharmaJcoL, 78 [1914), No. 1-2, pp. 24-82). — ^Analytical and feeding ex- 

 periments are reported in wbich was studied the phosphorus content of the 

 bodies of laboratory animals (dogs). In young animals of from 2 to 7 lbs. 

 weight the total phosphorus content of the organism showed very little varia- 

 tion and averaged 0.6 per cent of the total body weight; Of the total phos- 

 phorus content 0.15 per cent was found in the muscle, 0.2 per cent in the central 

 nervous system, liver, and kidneys, and most of the remainder in the bones. 

 Lack of phosphorus in the diet decreased the percentage of phosphorus in the 

 body only when growth was indifferent. Under this condition the greatest 

 loss occurred in the bones. 



The chemical investigation of the phosphotungstate precipitate from rice 

 polishings, J. C. Drummond and C. Funk {Biochem. Jour., 8 {1914), No. 6, pp. 

 598-615). — The authors have failed to isolate the curative substance which 

 occurs in rice polishings, but have confirmed the presence of considerable 

 amounts of cholin and nicotinic acid and have detected betain, adenin, guanin, 

 and possibly guanidin. 



Experimental polyneuritis in birds as compared with human beri-beri, 

 E. Tasawa (Ztschr. Expt. Path. u. Ther., 17 {1915), No. 1, pp. 27-^6).— From 

 this summary and digest of experimental data the author concludes that the 

 etiology and effects of experimental polyneuritis are not identical with those 

 of beri-beri.

 {Trans. Nat. Assoc. Study Pellagra, 2 {1912), pp. XXVIII -[■409, pis. 7).— 

 Among the papers included may be mentioned : The Problem of Pellagra in 

 the United States, by R. Blue ; The Prevalence and Geographic Distribution of 

 Pellagra in the United States, by C. H. Lavinder; Pellagra — Some Facts in its 

 Epidemiology, by R. M. Grimm ; Can Pellagra Be a Disease Due to Deficiency 

 in Nutrition, by F. M. Sandwith; Contribution to the Alimentary Balance in 

 Pellagra, by J. Nicolaidi and U. Grille; and Metabolism in Pellagra, by V. C.

The presence of toxic bodies in expired air, G. Faemacbidis {PoUclin., Ses;. 

 Med,., 20 {1913), No. S, pp. 116-138, pi. 1, fig. 1; ahs. Hm ZentU. Biochem. u. 

 Biophys., 16 {1914), No. 11-12, p. 4^7). — The injection of the condensation 

 liquid of expired air into laboratory animals gave no toxicity with guinea pigs, 

 but with mice a tendency toward toxicity was apparent when compared with 

 the negative results obtained by injections of distilled water or physiological 

 salt solution. 



An automatic balance for use in metabolism experiments, E. Abdeehalden 

 {Skand. Arch. Physiol., 29 {1913), pp. 15-82, figs. 2).— An illustrated descrip- 

 tion is given of a balance which records ard registers photographically the 

 weight of small laboratory animals. 



[Report of the] nutrition laboratory, F, G. Benedict {Carnegie Inst. Wash- 

 ington Year Book, 13 {1914), pp. 285-297). — ^A brief summaiy and review of the 

 investigations being carried on. Notes regarding changes and improvement in 

 equipment, together with a brief review of the publications issued during the 

 year 1914, complete the report.
