Milk as affected by stable practices and subsequent handling, M. II. 

 ItKYNOLDS iAnitr. 1(7. h'cr., 32 (lOOS), No. (1, mi. U!l()-709, figs. 3, (hjins. 3). — 

 This is a paper read before the American Veterinary Medical Association at its 

 forty-fourth animal meetinjr and previonsly reported (K. S. R., 11), p. 11)0). 



The influence of the sugars on the secretion of milk, G. Piantoni {Arch. 

 FaniKicol. N/>r;-. c Sci. Aff., 7 (/.00,S), Ao.v. 7, pi). 32D-33G; S-0, vp. 337-36.',).— 

 Hypodermic injections of disaccharids administered to a goat produced effects 

 that varied with the amount injected. A small dose increased the amount of 

 milk secreted without altering the proportion of its constituents. Larger doses 

 diminished the quantity of milk and the percentage of milk sugar, and decreased 

 slightly the percentage of fat, but increased the flow of urine which showed- 

 traces of sugar. Monosaccharids i)roduce similar efl'ects jn'ovided doulde the 

 quantity is used. The sugar contained in the urine of the goat is lactose, 

 which conforms with the assertion of Porcher. 



On the variability of milk, O. von Wlndt {Skaiifl. Arc]i. PhijsioJ.,21 (1908), 

 No. 2-3, pp. 80-1 J,5; Mitt. Landw. Inst. Leipzig, 1908, No. 9, pp. 127-179).— 

 Various salts were added to the rations of milch cows and their effect upon 

 the chemical composition of the milk was studied. Some of the author's con- 

 clusions are as follows: 



Common salt, carbonate of lime, sodium phosphate, magnesium bromid, and 

 calcium glycero-phosphate appeared to have no influence on the composition 

 of milk. Acid calcium phosi)hate appears sometimes to influence favorably the 

 amount of fat and to increase the relative amount of original calcium. The 

 percentage of albumin does not increase toward the end of the lactation period. 

 Phosphorus, total nitrogen, and casein are the least variable, while chlorin, 

 Iiotasslum, and albumin are the most variable of milk constituents. 



The effect of rutting on the composition of cow's milk, O. Mezger (Ztschr. 

 Untrrsuch. Nalir. ii. (Icnuxsiiitl, 16 (1908), No. 5, pp. 273-281) .—The author 

 made chemical analyses of the milk of seven cows during the rutting period 

 and found that such variations as occur are largely due to the individuality 

 of the cows. In no case did the amount of fat-free dry matter vary to any 

 extent. 



On the composition of cow's milk of different breeds, with special refer- 

 ence to the lime and phosphoric acid content, T. Katayama {Landw. Vers. 

 f<t<it., 69 {1908). No. .')-6, pp. 3.'i2-3.)8). — Analyses were made of milk from 

 cattle of Roumania, Ceylon, Korea, Africa, and different German breeds, and 

 from the l>uft'alo. There was a great variation between individuals of the 

 same breed, but in the same iJidividual the lime and ])hosphoric acid content 

 varied but little from time to time. The lime cimtent varied from 0.14.') per 

 cent in the East Prussian Holland breed to 0.227 in the black and white East 

 Frisian. The phosphoric acid varie<l from l.n;^, jter cent in the buffalo to 0.209 

 in tlie Korean cattle. 



On the variations of the globules of milk, G. Ai.essi and E. Cabapelle 

 (Tfcr. Ili/g. rt Med. Iiifanf., 7 (1908), No. .',, pp. ,W9-.329, p/.s. 3).— A micro- 

 scoi)ic examination was made of milk from the goat, dog, guinea pig, and cow, 

 as well as of human milk. The globuh's varied much in form and in size 

 under normal as well as al)normal conditions. In some cases the fatty sub- 

 stance did not appear to All the entire globule, while in other cases the pres- 

 ence of a viscous material caused the globules to form clusters. Pathological 

 conditions cause many changes in the fonn and character of the globules.
