firmed. On the contrary, a very marked effect was noted. In its action on blood 

 pressure and on blood clotting, Vauglian's crude soluble poison strongly resembles 

 the proteoses. Vaughan's preparation differs from the proteoses in that it pro- 

 duces marked symptoms or even death in the rabbit in relatively small doses. 

 Boiling with dilute hydrochloric acid to the abiuret stage destroys the toxicity 

 of Vaughan's product." 



The character of the water-soluble nitrogen of some common feeding 

 stuffs, E. B. Hart and W. H. Bentley (Jour. Biol. Chcm., 22 (1915), Xo. 3, pp. 

 ^77-.'f83). — In dissecting the water-soluble nitrogen of some feeding materials 

 for the purpose of securing a clearer picture of the composition of the so-called 

 " amid " nitrogen, the authors found that this material " is largely composed of 

 free amino acids and peptid linkings. In most cases the nitrogen in these struc- 

 tures constitutes 50 to 70 per cent of the water-soluble nitrogen. The acid amid 

 nitrogen is relatively small, seldom exceeding 20 per cent of the the water-.soluble 

 nitrogen, and more often being below 10 per cent. Corn stover Is an interesting 

 exception, showing approximately 40 per cent of the water-soluble nitrogen in 

 acid amid form. The ammonia nitrogen rarely exceeded 5 per cent of the total 

 water-soluble nitrogen, and in some instances was wholly absent." 



Utilization of rice straw, N. Novelu (Gior. Risicolt., 5 (1915), Xo. 9, pp. 

 I.'f7-154, fiff- !)■ — The average digestible nutrients of rice straw are given as 

 protein 1 per cent, fat 0.44 per cent, and carl>ol\ydrates 28.63 per cent. Ensiled 

 rice straw has been found to be a desirable feed material. 



Analysis of peanut oil cake, A. G. Holborow (Rhodesia Agr. Jour., 12 

 (1915), No. 4, pp. 527, 528). — The following analysis is given of peanut oil 

 cake : Moisture, 10.38 per cent ; protein, 41.18 ; ether extract, 10.96 ; nitrogen-free 

 extract, 20.82 ; crude fiber, 3.08, and ash, 3.08 per cent. 



Inorganic fodder (Sci. Amcr., 113 (1915), Xo. 1, pp. 8, 9.) — Announcement 

 is made of an invention at the Institute of Fermentation Industries, Berlin, 

 which will allow a nouri.'^hiug yeast contafning more than 50 per cent of albumin 

 to be prepared from sugar and ammonium sulphate. In order to supply the 

 albumin, sugar is " fertilized " with ammonia, potash, and magnesia, in the form 

 of their salts, after which some yeast is 'ntroduc^d and a strong air current 

 applied. The yeast then absorbs the sugar and the " fertilizer," thus resulting 

 in the formation of a highly albuminous yeast. It Is claimed that the dry yeast 

 obtained constitutes an excellent nourishing fodder for cattle and horses. 



Feeding stuffs report, 1914, J. W. Kellogg (Pcnn. Dcpt. Agr. Bui. 265 

 (1915) pp. 221). — Analyses are given of cotton-,seetl meal, llnseetl meal, dis- 

 tillers' dried grain (from corn and rye), brewers' drletl grains, malt sprouts, 

 corn gluten feed, corn gluten meal, hominy feed, corn bran, corn feeil meal, low 

 grade flour, wheat middlings, wheat bran, rye middlings, buckwheat middlings, 

 alfalfa meal, dried beet pulp, and various mixed and proprietary feo<ls. 



A system of recording types of mating in experimental breeding opera- 

 tions, R. Pearl (Sciowc, n. scr., ^2 (1915), Xo. 1081, pp. 383-386, fig. i).— The 

 author describes a system of recording types of mating In experimental breed- 

 ing operations which is thought to aid in expressing adequately and completely, 

 and at the same time brictly and simply, the general nature or type of the pedi- 

 gree by which particular individuals in the F: and Fs generations are descended. 



The amount of nuti-iment required by fattening cattle, F. Ho.ncamp et al. 

 {Ber. Landio. Rcichsamtc Inncrn, Xo. 36 (1914). pp. 130). — This Is a review of 

 experiments conducted at eight substations on the relative value of rich and 

 poor rations for cattle feeding. A ration rich In starch value (about 13..") kg. 

 per 1,000 kg. live weight) produced an average daily gain per head of 1.023 kg., 

 and a ration poor in starch value (about 11.5 kg. per 1,000 kg. live weight), 

 0.949 kg.
