584 EXPERIMENT STATION RECORD. 



absence of antiseptics bacterial growth is possible, resulting in the production of fat. 

 Fat may be also formed from pure albumins in a nonsterile medium. 



The general conclusion is drawn that the formation of fat from protein with the aid 

 of baeteria was as definitely shown as the fact that such formation could not occur 

 without bacterial aid. 



On the chemical composition of human feces on different diet, N. P. SchieRt 

 beck {Overs. K. Danske Videmh. Selsk. ForhandL, 1904, No. 2, II. pp. 28-51; Arch. 

 Hyg., 51 {1904), No. I, pp. 62-95). — The author reviews the work of other inves- 

 tigators on the composition and fuel value of feces from widely differing diet, and 

 gives the results of experiments in this line planned to throw additional light on the 

 subject. 



The experiments were conducted with 3 persons on ordinary mixed diets. The 

 data for total ether extract and ash were generally found almost constant for the 

 same individuals irrespective of the character of the diet, and the same was found to 

 be the case with the proportion of albuminoid nitrogen, cellulose, and pentosans in 

 the feces. In the case of different individuals, however, the nitrogen content of the 

 feces differed greatly, 3 types being noticed, one with a nitrogen content of about 4 

 per cent with every diet, another with 6 to 7 per cent, and a third varying according 

 to the character of the diet from 4 per cent in the case of coarse foods to 7 or 8 per 

 cent when only a small amount of feces was voided. 



Marked differences were observed in the percentage utilization of the dry matter, 

 total nitrogen, and albuminoid nitrogen of the food on varying diets, while fat, ash, 

 and carbohydrates showed a fairly uniform utilization in all cases. — P. w. woll. 



ANIMAL PRODUCTION. 



First report on concentrated feeding stuffs and cotton-seed meal, P>. W. 

 Kilgore, C. D. Harris, J. M. Pickel, and F. C. Lamb {Bui. North Carolina StaU Bd. 

 Agr., 24 ( 1908), No. 12, pp. 8-86).— The text of the State law regulating the sale of 

 concentrated commercial feeding stuffs and the act regulating the sale, inspection, 

 and branding of cotton-seed meal are quoted, and chemical and microscopical analy- 

 ses made in compliance with the law reported for a number of samples of wheat bran, 

 corn bran, mixture of wheat and corn bran, bran and shorts, shorts, chops, mixed 

 or proprietary cow feeds, commercial mixed feeds, mill feeds, middlings, peanut mid- 

 dlings, rice meal, rice bran, and rice product, ship stuff, chicken feed, horse feed, 

 and pig feeds, soy beans and corn, distillery slop, red dog flour, and cotton-seed meal. 



Of the 37 samples of wheat bran examined 10 contained com bran. Of the 123 

 samples of cotton-seed meal examined 102 contained as much protein as is required 

 by the standard or more, while 21 samples were below the legal standard. 



The authors point out that corn bran, rice chaff, ground corn cobs, peanut hulls, 

 peanut middlings, and similar products when mixed with I tetter feeding stuffs, with- 

 out proper label or guaranty to indicate their presence, ought to be regarded as 

 adulterants, and that the examinations reported show that such materials are being 

 used quite frequently in the stock feeds for sale in the State. 



Inspection of feeding stuffs, W. H. Jordan and F. D. Fuller {New York Stat* 

 Sta. Bui. 255, pp. 341-366).— The changes made in the feeding-stuff law by the State 

 legislature of 1904 are noted, and a report given of the analyses of 203 samples, rep- 

 resenting 203 brands, of cotton-seed meal, linseed meal, old and new process, dried 

 distillers' grains, brewers' grains, malt sprouts, gluten meal and feed, germ oil meal, 

 germaline, hominy feed, wheat bran and middlings, oats and oat by-products, com- 

 pounded feeds, including cereal breakfast food by-products, proprietary feeds and 

 similar goods, barley feed and meal, beet pulp, mixed poultry rations, scratching 

 food, poultry bone, meat meal, beef scraps, Mood meal, and similar products. At 

 least 52 of the samples showed a larger deficit in protein than was regarded by the
