474 EXPERIMENT STATION RECOED. 



Agra and Oudh, Agr. Ser., 191S, Bui. 29, pp. i^).- -Among the remedies proposed 

 for the improvement of the town's milk supply are those of municipal control 

 and management of dairies, community breeding schemes, and provisions for 

 town pastures. It is stated that in these Provinces the main difficulties in the 

 way of development of the milk industry for supplying large towns consist of 

 (1) the small capital of the dairymen and the absence of any form of associa- 

 tion among them, (2) the want of proper accommodations, (3) the poverty of 

 most of the breeds of cattle of these Provinces as milkers, (4) the absence of 

 grazing ground for dry cattle, and (5) the scarcity and high price of fodder. 



Certified milk, T. C. McCleave {Jour. Amer. Med. A^soc, 61 {1913), No. 23, 

 pp. 2031-2035). — An account of the origin and development of the certified milk 

 movement, together with a detailed discussion of the methods of organizing 

 and the duties of city milk commissions. 



[Reports of the state dairy and food commissioner and the state chemist 

 on dairy products], W. Hanson and H. Harms {Bien. Rpts. State Dairy and 

 Food Comr., State Chem., and State Dairy and Food Bur. Utah, 1911-12, pp. 

 29-36, 79-105). — These reports discuss the enforcement of the state laws relative 

 to the sale of dairy products in Utah, including a special report on shrinkage 

 in butter. 



Weighings of 15 samples of butter showed an average loss in moisture in 6 

 weeks of 2.78 per cent. Fifteen other samples showed after about 1 month a 

 loss of 2.18 per cent of moisture, while 5 samples of cold storage butter lost 

 1.34 per cent. 



Daily changes in the specific gravity and fat content of milk, Klose 

 {Milchw. ZentU., 42 {1913), No. 13, pp. 385-392) .—The specific gravity and fat 

 content of morning, noon, and night milkings were taken daily for several 

 months in a herd of 70 milch cows. 



The daily changes in specific gravity ranged between and 0.0037 and in fat 

 between and 0.7 per cent. During March 10 per cent of the changes in 

 specific gravity ranged between 0.001 and 0.0019 and 18.9 per cent of the fat 

 changes between 0.2 and 0.45 per cent. In May 33 per cent of the specific 

 gravity changes were between 0.001 and 0.0017, and 30 per cent of the fat 

 changes between 0.2 and 0.5 per cent. In July 31.1 per cent of the specific 

 gravity changes were between 0.001 and 0.0037, and 34.4 per cent of the fat 

 changes between 0.2 and 0.7 per cent. In October 10 per cent of the specific 

 gravity changes were between 0.001 and 0.0018, and 34.4 per cent of the fat 

 changes between 0.2 and 0.5 per cent. 



The elimination of artificial coloring matter by the udder, P. Sisley and 

 C. PoECHEB {Compt. Rend. Acad. Sci. {Parish, 157 {1913), No. 17, pp. 729-732).— 

 Experiments were conducted on she goats with various coloring materials. 



Uranium produced only a slight trace of coloring in the urine, both when 

 taken into the stomach and when injected into the jugular vein. No change 

 was noted in the milk and it is concluded that the udder opposes the passage of 

 certain substances. Rhodamin when taken into the stomach produced rose- 

 colored milk after 10 hours. After that the coloring rapidly diminished. The 

 coloring was also present in the urine. The proportion of rhodamin present in 

 the milk was small compared with the amount taken into the body. One gm. 

 of methylene blue produced no effect on either the milk or urine : 3 gm. produced 

 a trace in the milk and urine. Ponceau taken into the stomach showed no 

 presence in the milk. With dimethylamino-azobenzene, the milk showed a rose 

 coloration on the addition of a small quantity of HCl. However, the elimina- 

 tion was transient. 



These results confirm earlier investigations (Dechavanne, 1909). They indi- 

 cate first, the very diffusibility of these coloring matters in the animal body;
