were made of a iiuiiiIkm- of samples of eotton-seed meal, linseed meal, jrhiteii meal, 

 Lrluteii feed, dried distillers' jirains, malt sprouts, wheat ])y-prodiU'ts, dairy fei'ds, 

 oat middlings, and rye feed. 



The eomparative value of different feeding stuffs is briefly discussed; several typical 

 mixtures for dairy animals are suggested, and four rations quoted, which are actually 

 fed l)y dairymen in JNIassachusetts. 



Commercial feeding stuffs, II. J. Wheeler et al. {Rhode Mand Hia. Bui. OS, 

 l>p. 63-78) . — In accordance with the State feeding-stuff law, analyses are reported of a 

 number of samples of gluten meals and feed, distillers' grains, barley si)routs, wheat 

 feeds including mixed feeds, proprietary feeds, hominy and chop feeds, provender, 

 corn meal, peanut liran, l)eef scraps, and bone and meat meal. 



'■The lots of hominy and provender were quite generally poor, yet . . . this in 

 many cases, particularly as concerns the provenders, was due to the inferior quality 

 of certain of the cereals that were grown in 1902. The poor quality of the 'mixed 

 feeds' was shown to have been due in most cases to gross adulteration with corncol^, 

 and possibly other materials of little feeding value." 



Licensed commercial feeding stuffs, F. W. Woll ( Wiscomin Sl<t. Bui. 109, 

 pp. 3, .}, <j) . — A list is given of 44 brands of connnercial feeding stuffs licensed for 

 sale in the State, with the guaranteed composition of each. The State feeding-stuff 

 law is quoted. 



Condimental feeds, L. Weil {Pharm. Ztg., 4S {1903), pp. 606, 607; abs.inZlxclir. 

 Viih'rsnrh. ^(dn: u. Gcmmmtl., 7 {1904), No. 3, pp. 190, i5i).— The condimental feeds 

 examined were made up of glauber salts, chalk, gentian powder, anis, and other 

 common drugs with the addition of concentrated feeds in some cases. 



The use of molasses as a feeding material, E. Curot, trans, by J. A. Munn 

 {Ballicre, Tindall tO Cox; rev. in Mark Lane Express, SS {1903), No. 3746, pp. 22). — 

 A summary of information regarding the feeding value of molasses. 



A locally manufactured cattle food {Agr. Ga~. New South Wales, I4 {1903), No. 

 7, p. 6/ih) . — An analysis is reported of Maizena cattle food. 



The adulteration of feeding stuffs; rice husks and coffee bean husks {Brit- 

 i.sli Fond Jour., 6 {1904), No. 63, ]}p. 55, 56). — A note on the use of rice husks and 

 coffee-bean husks as adulterants of feeding stuffs in Great Britain. 



Results of some recent agricultural experiments, D. A. Gilchrist {Neuxastle- 

 on-Tiine, [1902'], pp. 26). — Recent English experiments with feeding stuffs and fer- 

 tilizers are briefly summarized. 



Concerning the so-called metallic compounds of proteids in relation to the 

 theory of chemical equilibrium, G. G.vleotti {Ztsehr. I'ln/slol. Chem., 40 {1904), 

 No. 5-6, pp. 492-549, Jhjs. 9). — Experiments are reported and discussed. 



On the percentage of fat in different types of muscle, J. B. Leathes {.Tour. 

 J'hi/slol., 31 {191)4), No. 1, Proc. Physiol. Soc, 1904, pp- IT, III).— The amount of 

 insolul)le fatty acids present as fats, soaps, etc., in different types of muscular tissue 

 (raljbit and cat) was determined. The dried and powdered muscular tissue was 

 extracted twice according to Rosenfeld's method and the combined chloroform and 

 alcohol extracts saponified with alcoholic potash. 



The soaps dissolved in a large volume of water were precipitated with sulphuric 

 acid and heated until a sharp separation took place. The i)reci[)itated fatty acids 

 were filtered while hot, wa.shed with a large amount of water, dried on a filter in 

 vacuo, and extracted with petroleum ether, the extracts being filtered, dried, and 

 weighed in the usual way. The smallest amount of fat was found in the semimem- 

 branosus; the largest amount on an average in the heart. In one case with a rabbit 

 the largest amount was found in the soleus. 



On the adaptation of the pancreas, F. A. BviNHRiixiE {British Med. Jour., 

 1904, No. 2257, pp. 778-781). — Experiments were carried on with pancreatic juice 

 obtained from dogs and cats, some of which liad sjjecial reference to the influence of
