572 EXPERIMENT STATION RECORD. 



"There have been very few samples of . . . [oondimentnl] feeds received in 

 this laboratory. These feeds are a mixture of sulphur, salt, saltpeter, epsom 

 salts, Glauber's salts, sodium bicarbonate, fenugreek seeds, fennel seeds, char- 

 coal, red and black peppers, ground bone, Venetian red, and anise. This class of 

 feeds generaly carry attractive names, and the manufacturers make great 

 claims regarding their curative properties. These feeds are too expensive for 

 the economical feeder. 



" If your animals are in good health they need no condition powders or tonics, 

 and if they are sick it is cheaper to consult a veterinarian." 



Commercial feeding stuffs in Pennsylvania in 1905, P. D. Fuller {Pom. 

 Dcpt. Agr. Bui. Ifi5, pp. 51). — The 339 samples of feeding stuffs examined under 

 the provisions of the State feeding-stuff law included cotton-seed meal, linseed 

 meals, flaxseed meals, distillery and brewery by-products, gluten meal and 

 other corn by-products, corn meal, corn-meal feed, corn flour, low-grade wheat 

 flour, wheat middlings, wheat bran, bran and middlings, oat by-products, mixed 

 and proprietary feeds, proprietary poultry feeds, barley, barley feeds, and dried 

 sugar-beet pulp. 



Of the wheat offals examined. 11 were deficient in fat, 13 in protein, and 22 in 

 both protein and fat. Six feeds were found to be adulterated, namely, " wheat 

 bran with rice hulls, wheat bran with corncob, 'chop' (corn and light oats) 

 with coffee hiills, 2 samples of corn and oats chop, and 1 sample of corn, oats, 

 and barley with oat hulls. Wheat offals were inferior in quality, which was due 

 largely to climatic conditions. 



" The oat feeds on the market contain a large proportion of oat hulls. There 

 are on the market, however, a large variety of feeding stuffs of good quality 

 fi-om which the farmer should have fio difficulty in choosing those best adapted 

 to his need. As long as the farmer can raise plenty of corn, hay, and oats he 

 can not afford to purchase any feeding stuff containing less than 14 per cent of 

 protein." 



The poisonous properties of peanut-oil cake, E. Kkijger (Chem. Ztg., 30 

 {1906), No. 81, p. 999). — Brief notes are given regarding a case of poisoning 

 attributed to grovuid peanut-oil cake. In the author's opinion, this was due 

 to the accidental presence of castor bean, to decomposition, or to some similar 

 cause, as investigations failed to reveal toxic properties and other portions of 

 the same consignment of meal were apparently harmless. 



Purin bodies in the urine of pigs, cattle, and horses, A. Schittenheim 

 and G. Bendix {Ztschr. Physiol. Chcm.. .',& (1906), No. 2, pp. i^O-i^^).— The 

 amount of purin bases in pigs' urine is greater than that of uric acid and 

 increases markedly in hunger. In cattle the ratio is about the same as with 

 man, namely, considerable uric acid and little of the basic bodies. With horses, 

 according to the author, the amount of purin bases is 7 or 8 times as great as 

 the amount of uric acid. Apparently the purin metabolism of different kinds 

 of animals varies markedly. 



The effect of raw meat on young animals, C. Richet {Compt. Rend. Acad. 

 Set. [Paris], lJi2 {1906), No. 9. pp. 522-52 Ji). — The experiments were made with 

 young dogs and covered G months. In 3 of the tests cooked meat alternated in 

 5-day periods with porridge (made of rice, milk, and sugar), with raw meat, 

 and with cheese. In the 4 remaining tests a diet of cooked meat, raw meat, 

 porridge, and cheest^ alternated in 5-day periods, with fasting periods of like 

 duration. In the feeding ])eriods in which the diet varied the dogs remained 

 in good condition. When fasting during each alternate jieriod the most satis- 

 factory results were obtained on raw meat. The dogs lost 10 per cent of their 

 weight in 3 mouths, then made good the loss and practically maintained a con-
