EXPERIMENT STATION RECORD. 



The quantitative determination of organic-phosphorus compound in 

 grape seeds and natural wines, J. Weirich and G. Qktlieb (Chem. Ztg., 28 

 (1904), No. //', pp. 153, 154; Arch. Pharm., 242 (1904), No. 2, pp. 138-143).— The 

 identification of small quantities of lecithin in certain wines, according to the authors, 

 explains in part their physiological properties. 



Cucurbit seed oil, J. Schdmkow ( Vyestnik Shirov. Veshch., 4 (1903), pp. 29-31; 

 abs. in Ztschr. Untersuch. Nahr. u. Genussmtl., 8 (1904), No. 7, p. 435). — According to 

 the author's analyses, Russian seed contained more oil than German seed, which is 

 explained as due to the drier climate and soil. 



Concerning oil from olive pits, N. Passerini (>SVr/r. Spcr. Agr. Ital., 37 (1904), 

 No. 7-8, pp. 600-609). — The data reported have to do with oil from the pits of olives, 

 especially with reference to its injurious effect on the quality of olive oil. 



The nucleon in European oysters, E. Cavazzani (Zentbl. Physiol., 18 (1904), 

 No. 21, pp. 666-668). — Determinations of the nucleon (sarco-phosphoric aeid) in 

 European oysters (Ostrea edulis) are reported, as well as the percentage of nitrogen 

 and phosphorus in the nucleon. Tin- amount of nucleon present on an average 

 was 0.3725 per cent, which the author states is more than twice the quantity found 

 in muscles, kidneys, ami other organs of mammalia. The results are discussed in 

 relation to the occurrence and function of nucleon in plants. 



The chemical changes of meat brought about by mold, I'. \V. Butjagin 

 (Arch. Hyg., 52(1905), No. 1, pp. 1-21, pin. 2). — The author reports investigations 

 on the changes brought about in meat by Penicillium glaucum and Aspergillus niger. 

 It was found that the growth of these molds caused a loss in dry matter and nitrogen 

 and an increase in the amount of water-soluble nitrogenous bodies. The percentage 

 amount of ether extract in the dry matter diminished, especially during the first 

 month, and the amount of extractives was markedly increased, while the alkalinity 

 of the meat increased slowly, being greater in the case of /'. glaucum than in the 

 case of A. niger. By the growth of these molds a gradually increasing amount of 

 volatile acid was produced. The effect on the production of other bodies is also 

 spoken of, the general conclusion being reached that the Penicillium studied destroys 

 the constituents of meat more quickly than the Aspergillus. 



Bad results which attend the use of preserved meat; causes and ways of 

 preventing them, Unix and Moxiek (Compl. Rend. Soc. Biol. [Paris'], 56 (1904), 

 No. 8, pp. 383-385). — Thorough inspection of live stock is insisted upon before pres- 

 ervation and the rejection of all suspicious animals. 



ANIMAL PRODUCTION. 



Analyses of cattle foods and miscellaneous substances, M. E. Jaffa (Cali- 

 fornia sin. Ji/it. 1904, PP- 49-53). — Analyses are reported of carob beans, Sesbaniu 

 macrocarpa, cactus plant, sesame oil-cake meal, cotton-seed oil-cake meal, milk, 

 infant foods, and condensed milk, as well as a number of determinations of the fat 

 in cream and of the gluten in wheat. Several of the analyses of cattle foods follow:
