Average composition of feeding stuffs, W. Frear {Pennsylvania Dept. Agr. 

 Bui. 87, pp. ^/).— Data showing the composition and digestible nutrients in feeding 

 stuffs are reprinted from various sources. A method for computing the composition 

 of mixed feeds is given. 



Concentrated feeding stuffs and fertilizers licensed for sale in Wisconsin, 

 1902, F. W. WoLL ( Wisconsin Sta. Bui. 90, pp. S).—X list of 23 brands of feeding 

 stuffs and 6 of fertilizers licensed for sale in Wisconsin during 1902, with the text of 

 the Wisconsin feerling-stuff law and the fertilizer law. 



Analyses of grasses and fodder plants, J. C. Bwc^^icw {Queensland Agr. Jour., 

 9 {1901), Xo. 6, pp. 572-575). — Proximate analyses are reported of hay and grass 

 from alfalfa {Medicago sativa), prairie grass {Bromus unioloides), cocksfoot grass 

 {Dactylis glomerata), and Paspalum dilatatum. The author also reports ash analyses 

 of different sorts of hay. 



Dried brewers' grains, T. Dietrich {Landu: Vers. Stat., 5G {1901), Xo. 2-3, pp. 

 207-256, figs. 6) . — A summary of the available information on the production and 

 feeding value of brewers' grains. A number of forms of apparatus for drying this 

 material are described. 



Dried distillery refuse, T. Dietrich {Landu: Vers. Stat., 56 (1901), Xo. 2-3, pp. 

 257-262). — The composition and feeding value of distillery refuse is discussed, a 

 number of investigations on the subject being summarized. 



Tang, P. R. Sollied {Tidsskr. Xorske Landbr., 1901, pjp. 13-30; ahs. in fjentbl. 

 Agr. Chem., 30 {1901), Xo. 6, pp. 375-377).— The composition of a number of sorts of 

 seaweeds used as feeding stuffs is given, together with results of artificial digestion 

 experiments. According to the author, the fact should not be overlooked that 

 seaweeds contain a considerable amount of pentosans, and on this account may be 

 satisfactorily combined with materials rich in protein. The iodin which the jilants 

 contain is also regarded as of importance. 



Silkworm excrement as a feeding stuff, G. E. Rasetti {Sfaz. Sper. Agr. Ital., 

 34 {1901), Xo. 9, pp. S65-S80,fig. i) .—Analytical data are reported, showing that 

 the riiaterial studied consisted largely of carbohydrates. 



On the preservation of feeding cakes, R. W. Tuixzixg {Landu: Vers. Stat., 

 56 {1901), Xo. 2-3, pip. 153, 154)- — Experiments which are briefly reported led to the 

 conclusion that the increase in water content observed when lin.seed cake is stored 

 is due to the growth of mold. 



Experiments on the utilization of the protein of gluten, O. Kellxer ( Landu: 

 Vers. Stat., 56 (1901), Xo. 2-3, pp. 149-152). — Exj)erimeiit showed that considerable 

 more ether extract could be obtained from gluten by digesting with pepsin and 

 hydrochloric acid before extracting with ether than was the case by the ordinary 

 method. On the basis of such experimental work the author calculates that the 

 physiological nutritive value of 1 gm. of gluten protein is equal to 4.697 calories. 

 The work is discussed in relation to the author's earlier investigations (E. S. R., 10, 

 p. 669), the opinion being expressed that the new values do not modify the conclu- 

 sions previously reached. 



Methods of analyzing blood and the value of such data for studying pro- 

 teid metabolism, (J. Ascoi.i (Arch. Plnixiol. [f 'finger], S7 {l:iOl), Xt,. l-.\ jip. J03- 

 115). — Experiments are descrilx'd and discussed. 



Experiments on artificially lowering the protein metabolism of a sheep 

 having fever, S. Weber {Arclt. E.rper. Path. n. PharmakoL, 47 {1901), pp. 19-47;
