G84 EXPERIMENT STATION RECORD. 



Miscellaneous cattle food analyses, W. Frear {P('nn.vjlrKnia Sta. Upt. 1901, 

 ])]). 110-110). — In addition to the analyses reported a])Ove, the station has analyzed 

 a number of feeding stuffs submitted by individuals, the analyses, it is stated, in a 

 number of cases being incomplete. The feeding stuffs include cotton-seed meal, flax- 

 seed meal, linseed meal (old and new process), wheat bran, wheat feed, corn meal, 

 steam cooked corn-meal feed, gluten feed, corn bran, hominy feed, cerealine feeds, 

 oat feed, buckwheat middlings, buckwheat feed, cocoanut meal, dried l)rewers' grains, 

 dried distillery feed, sugar-beet feed, dog meal, meat scrap, cereal breakfast food 

 by-products, and mixed feeds. 



The by-products obtained in grinding* wheat and rye, F. Otto {Inany. Diss., 

 Gi)tt!n(jeri, 1901; (ih.<i. In Coithl. Acjr. f'linn., 31 {1902), No. 9, pp. 606-610).— K com- 

 parison was made of the German and imported rye and wheat, the composition of 

 different varieties of these grains and their milling products being reported, as well 

 as results of digestion experiments made with sheep. 



The purchase of feeding stuffs {Ed. Agr. [7vO»don], Leajhi 74, pp. 1-12). — A 

 ])(>l)ular discussion of the i>rinciples of nutrition and the different classes of feeding 

 stuffs. 



Report on molasses feeds, C. V. Garola {Compt. Rend. Cony. Soc. Ailment, lint. 

 Int., 6 {1902), pp. 1-15, dgms. 3). — Mixtures of molasses with peat, peanut hulls, 

 sesame and peanut hulls, and with straw were described and the favorable results 

 olitained in feeding such mixtures to sheep and hor,ses briefly noted. The rations 

 containing the molasses mixtures were cheaper than those made of more common 

 feeding stuffs. 



The influence of lecithin on the development of the skeleton and nerve 

 tissue, A. I)ES(iREZ and A. Zaky {Coynpf. Rend. Acad. Set. I'nris, 134 {1902), No. 20, 

 ]>/i. 1166-1168). — From experiments with Guinea pigs, rabbits, and dogs the conclu- 

 sion is drawn that feeding lecithin rendered the food more effective, especially in 

 tl:e formation of the skeleton and nervous system. 



Study of the "way in which lecithin acts in the animal body, A. DEscjREzand 

 A. Zaky {Compt. Rend. Covg. Soc. Acad. Set. Paris, 134 {1902), No. 25, jtp. 1522, 

 1523). — Experiments, which are briefly reported, made with guinea pigs led to the 

 conclusion that the favorable effects which were observed to follow the feeding of 

 lecithin were not due to glycero-phosphoric acid (the acid radical of lecithin), but to 

 the basic portion. It was found that cholin and betain exercised a favorable effect, 

 though in a less degree than lecithin, upon the formation of nitrogenous tissue and 

 L'aiuH in weight. 



Concerning the metabolism of growing dogs, E. RosT(/lr/'v. 7v'. <iesnndheitsamte, 

 IS {1901), No. 2, pp. 206-21S, pi. 1). — From experiments re]torted in detail the con- 

 clusion is drawn that the amount of nitrogen retaine<l was greater than could be 

 accounted for by the gain in body weight. 



Methods of steer feeding, G. C. Watson and A. K. Risser {Pennsylvania Sta. 

 Rpt. 1901, pp. 211-222). — The comparative merits of fattening steers in pens and 

 stalls was studied in continuation of previous work (E. S. R., 12, p. 875), the State 

 department of agriculture cooperating with the Pennsylvania Station. Of the 2 tests 

 reported the first was made with 3 lots, lot 1 containing 10 animals and lots 2 and 3 

 containing G each. The steers in lot 1 occupied a box stall having a space equiv- 

 alent to that of 10 ordinary stalls. Each of the animals in lots 2 and 3 was kept 

 in a separate stall. Lots 1 and 2 were supplied with water 1)y means of an automatic 

 basin and lot 3 was watered daily in a yard, as it was desired to test the merits of 

 ^different methods of watering as well as other points which have to do with the 

 comparative amount of labor required to care for steers fattened under different 

 conditions. All of the animals were led a grain ration consisting of corn meal and 

 wheat bran, 9:1, in addition to hay and corn stover. At the beginning of the test 

 the average weight of the steers was not far from 950 lbs. each. During the 14 weeks
