Ostrich breeding, A. Menegaux (Agr. Prat. Pays Chaiids, 12 {1912), Nos. 

 Ill, pp. Ul-459; 112, pp. 22-30; 113, pp. 111-131; IIJ,, pp. 203-215; 116, pp. 

 S80-39J,; 111, pp. Jf61-481; 13 (1913), Nos. 118, pp. 19-35; 119, pp. 112-129; 

 120, pp. 196-21^, figs. 23). — These articles treat of tlie different varieties of 

 ostriches, the anatomy of the ostrich feather, the down of the ostrich, the 

 market for plumes, and the methods of breeding in different countries, and de- 

 scribe the terms applied to commercial plumes. 



Preservation of eggs by coating with paraffin (Agr. Gaz. N. S. Wales, 21 

 (1910), p. 990; Rpt. Govt. Bur. Microbiol. N. S. Wales, 2 (1910-11), p. 209).— A 

 brief report is given of experiments in preserving eggs by sealing with gelatin 

 and with a mixture of paraffin and vaselin. 



At the end of 12 months those treated with gelatin were not well preserved 

 and had evaporated to a large extent. The paraffin-treated eggs, however, 

 neither evaporated nor decomposed. The white was quite fluid, and although 

 the yolk membrane was easily rupHired the yolk was turned out in an unbroken 

 state. When boiled these eggs had an old taste, but otherwise were satisfac- 

 tory. The control eggs, which received no treatment, had become putrid and 

 most of them had become dry through evaporation. 



DAIRY FARMING— DAIRYING. 



Dairy terminology, B. Maetiny (Milchw. ZentU., 42 (1913), No. 2, pp. 

 34-39).— A list is given of some synonymous dairy terms, with a brief discus- 

 sion of the exact meaning of some of the more important ones. 



Report of the activities of Alnarp Agricultural and Dairy Institute and 

 Agricultural School, 1911, H, L. O. Winbebg (Malmo, 1912, pp. 59+32).— 

 This report includes accounts of the educational work of the year at the insti- 

 tutions given, and also the administrative report of the institute and the farm 

 report of Alnarp estate. 



Report on further experiments on the feeding of dairy cows at Offerton 

 Hall, F. P. Walkee (Durham County Council, Ed. Com., Offerton Bui. 4, 1913, 

 pp. 40). — In 2 experiments lasting 7 weeks each cows fed soy-bean cake pro- 

 duced slightly more milk than those fed cotton-seed cake. In 2 other tests of 8 

 weeks each cows fed concentrates consisting of soy-bean cake, barley meal, and 

 corn meal in the form of " crowdy," a stiff porridge, produced practically the 

 same amount of milk and fat as those fed the same concentrates dry, and the 

 expense and trouble of making it is therefore considered probably unwarranted. 



In 2 other S weeks' tests cows fed Sudan durra, or Kaflr corn meal, produced 

 practically the same amount of milk and milk fat as those fed corn meal. 



Records of 24 cows milked 3 times daily for 2 days showed that 46 per cent 

 of the milk was yielded at 6 a. m., 33 per cent at noon, and 21 per cent at 6 

 p. m., while 10 cows milked twice daily yielded 48 per cent in the morning and 

 .52 per cent in the evening. The poorest milk with 3 milkings was at 6 a. m. 

 and the richest at noon. With 2 milkings the richest milk was obtained in the 

 evening. 



Biological examination of the quality of milk, S. Pabaschtschuk (Milchw. 

 Zentbl., 42 (1913), No. 3, pp. 65-60, figs. 9; abs. in Cream, and Milk Plant Mo., 

 1 (1913), No. 1, pp. 30, 31). — The quality of milk was tested by studying the 

 development of 5 races of lactic acid bacteria, with the following results : 



The Danish streptococci gave an excellent curd in consistency and taste. 

 They required fresh milk and did not develop in milk not thoroughly chilled 

 immediately after milking and kept cold. A small diplococcus, which the 

 author brought from Jaroslav, Russia, gave a fine, thin curd, but its chief dis-
