72 EXPERIMENT STATION RECORD. 



tlie com feed^ — other than th<j.se named above — as well an nioi^t other feeds, are, as 

 a rule, sold without guaranties, which is contrary to law. 



"The only evidence of deliberate fraud in the feed market which is sliown by the 

 analyses, is the mixing of finely ground corncobs with wheat feed. . . . There are 

 in the feed market a considerable number of very inferior oat feeds, and mixed corn- 

 and-oat feeds, which contain a large proportion of hulls and chaff, and which can 

 not profitably be used by the stock feeder at any price. 



"The dairyman's chief concern in buying feeds to supplement his farm supply of 

 corn, stover, hay, etc., should be to buy, on the most reasonable terms, protein in 

 digestible and palatable forms. Seldom will it pay him to buy any feed containing 

 less than 12 to 15 ])er cent of crude protein." 



Analyses of commercial feeding stuffs, J. L. Hills ( Vermont Sta. Bui. 91, 

 pp. 39-52). — Analyses were made in accordance with the State feeding stuff law of a 

 number of samples of cotton-seed meal; linseed meal, old and new process; gluten 

 meals, and feeds; cereal breakfast food by-products, and other commercial feeds; 

 ground oats; wheat bran; wheat middlings; mixed wheat feed; buckwheat Ijran; 

 buckwheat middlings; buckwheat hulls; calf meal; ground beef scrap and poultry 

 feeds. According to the author none of the samples of cotton-seed meal, linseed 

 meal, or gluten products was adulterated, although several brands of the latter and 

 some of the germ oil meals were inferior to the guaranteed composition. 



"The oatmeal manufacturers' brands of oat feeds, corn-and-oat feeds, etc., were 

 found, as usual, more or less loaded with oat hulls. Some of these })rands are 

 extremely inferior. One is called a ground oats, yet carries less than half the pro- 

 tein which oats should contain. Another is nothing more nor less than finely ground 

 oat hulls, selling at |20 a ton. Ninety per cent of the provenders (other than the 

 output of the oatmeal mills) seem to be above reproach, while the remaining 10 per 

 cent are hardly more than open to question. The wheat offals appear to be of excel- 

 lent grade, no cases of adulteration l)eing found, but, on the contrary, exceptionally 

 high protein contents being observed." 



Indian food grains and fodders — their chemical composition, J. W. 

 Le.\ther (.l^r. Ledger {1901), No. 10 {Med. and Chem. ser., No. 14), pp. 349-376). — 

 Analyses are reported of Andropogon Jtalepensis, A. sorghum, Sorghum andropogon, 

 peanuts, (lats, Brassica campei^tris, cocoanut cake, a number of legumes, millets, etc. 



The composition of tendon mucoid, W. I). Cutter and W. J. Gies {Amev. 

 Jour. Physiol., 6 {1901), No. 3, pp. 155-172).— Among the conclusions drawn from a 

 chemical study of tendon mucoid were the following: 



"The average composition of mucoid separated from white fil)rous connective tis- 

 sue by the customary methods is very nearly the same as that of chondronuicoid and 

 osseomucoid. Thermochemical studies of the mucoids in tendon, cartilage, and bone 

 emphasize the j)robability that these bodies are very intimately related." 



The chemical constituents of tendinous tissue, L. BiEKCiEK and AV. J. Gies 

 {Amer. Jour. Phgsiol., 6 {1901), No. 4, pp- 219-231). — The composition of tendinous 

 tissue from a steer and a calf was studied. 



The composition of yellow fibrous connective tissue, G. W. V.vndegrift and 

 W. J. Gies {Amer. Jour. Bhi/siol., o {1901), No. 5, pp. 287-297). — A chemical study 

 of ligaments from a steer and a calf is reported. 



The nutritive value of gelatin, O. Krummacher {Zlsdtr. Biol., 42 {1901) pp. 

 242-260, dgm. 1). — On the basis of experimental data, including determinations of 

 the heat of combustion and feeding tests with a dog, the author concludes that gela- 

 tin supi)lies the body with energy and hence prevents the cleavage of protein. 

 When gelatin was fed in his experiments, the cleavage or protein was 62.6 j>er cent 

 less than during fasting.
