Cattle feeding in tbe United States with residuum beet pulps and molasses 

 {Sugar Beet, 21 {1900), No. 1, pp. 8, 9). — A brief account of the successful use of 

 sugar beet l)y-j)roducts as feeding stuffs. 



Use and abuse of rations, A. M. Soflk ( TeiuwsHei- Sta. /!/>!. 1899, i^p. 31-33). — 

 Brief pojuilar notes are given on this snl>ject. 



Investigations on the behavior of animal food in the human body, K. Micko, 

 P. MtJLLEK, H. PoDA, and W. Prausxitz [Zhchr. BioL, .i9 {1900), No. 2, pp. 277, 

 278). — A note on a series of investigations of which the following is the first. 



Concerning plasmon, a new protein preparation, II. Poda and W. Prausxitz 

 {Ztschr. Biol., .i9 {1900), No. 2, pp. 279-312). — A fnll account of experiments briefly 

 reported elsewhere.^ Plasmon, a preparation made from the casein of skim milk was 

 consumed as jiart of a mixed diet by several men. The digestibilit}' of the ration 

 was determined and the balance of income and outgo of nitrogen. The principal 

 conclusions follow: Plasmon is well assimilated. Only very small amounts are 

 excreted in the feces. As shown by the balance of income and outgo of nitrogen, 

 plasmon can replace meat in the diet. 



Comparative studies of the feces from plasmon and meat diet, K. Micko 

 (Z/.sr/(/'. B'kA., 39 {1900), No. 3, pjp. 430-450). — Continuing the work reported al)ove, 

 the author studied the feces when plasmon and meat were consumed, special atten- 

 tion being given to determining the ratio of nitrogen to ])hosphorus, the xanthin- 

 nitrogen and nuclein l)odies, casein, and paranuclein. 



In the author's opinion the investigation showed that there was no appreciable 

 quantity of undigested plasmon or its phosphorus compoimds, casein or paranuclein, 

 in the feces from plasmon. It was apparently completely digested, surpassing meat 

 in this respect. 



On the metabolism of matter in the living body, E. B. Rosa {Phjif. Rev., 10 

 {1900), No. 3,pj). 129-150). — A method for computing the balance of income and outgo 

 of oxygen and hydrogen from the data usually recorded in experiments with the 

 respiration calorimeter is described. The author T^elieves such calculations are useful 

 and that the weight of the subject should be determined at short intervals and this 

 and other data used as a check on the accuracy of the work. 



Farm superintendence, G. E. Day {Ontario Agr. Col. and Expl. Farm Rpt. 1899, 

 pp. 83-86, fig. 1). — Brief notes are given on farm superintendence; cattle, sheep, and 

 swine kept at the station: methods of feeding; and the financial affairs of the agri- 

 cultural college. 



White cattle: An inquiry into their origin and history, R. H. Wallace 

 {Reprint from Trans. Nat. Hist. Soc. Glasgow, n. ser., 5 {1897-1899), Nos. 2, pp. 220- 

 273, figs. 32, plx. 7; 3, pp. 403-457). — A large amount of historical and other data 

 leads the author to the conclusion that the white breed, commonly called Park 

 Cattle, and White Cattle, are descendants of domesticated cattle which became feral 

 many generations ago. Scotland is regarded as the source of the present English 

 herds of white cattle. The origin of the Scotch herds is not definitely settled. The 

 present publication is regarded as an introductory. An extended bibliography of 

 the sul>ject is given. 



Heavy, medium, and light meal rations for fattening steers, G. E. Day 

 {Ontario Agr. Col. and Expt. Farm Bid. 110, pp. 1-4). — Noted from otlier pul)iications 

 (E. S. R., 10, p. 277; 11, p. 664; 12, p. 872). 



Pasteurized v. raw skim milk for calves, (J. E. Day [Ontario Agr. Col. and 

 Expt. Farm Rpt. 1899, }). 67). — A brief account of a test in continuation of previous 

 work (E. S. R., 11, p. 666). The total gain in 4 weeks of 4 calves fed pasteurized skim
