506 EXPERIMENT STATION RECORD. 



the ether-extraction and the Gottlieb methods of fat determination. The author 

 corroborates the results obtained by Barthel ( E. S. R., 15, p. 1053), showing that the 

 extraction method will give too low results in the case of milk that has been churned 

 or subjected to considerable agitation at a temperature over 40° C. — f. w. woll. 



Sin-acid butyrometry (Milch Ztg., 33 (1904), No. 27-28, pp. 417-410, 436-438).— 

 A general description of a new method of milk analysis devised by A. Sichler, in 

 which the nonfatty solids are brought into solution by a salt solution, the composi- 

 tion of which is withheld from publication. The bottles used in this method are 

 somewhat similar to the Gerber milk-test bottles. It is accurate in comparison with 

 the Soxhlet and Gerber methods, and is claimed to be very simple in manipulation. —

The bacterial contamination of milk and its control, F. C. Harrison ( Trans. 

 Canad. Inst., 7 (1904), III, No. 15, pp. 467-496, figs. 17). — Practically the same as a 

 paper abstracted from another source (E. S. R., 15, p. 183). 



New bacterial species giving- the aroma to butter, Severin ( Messenger Imp. 

 Russ. Soc. Acclim. Animals and Plants, No. 11, pp. 8-14; abs. in Zhur. Opuiln. Agron. 

 {Jour. Expt. Landw.}, 5 (1904), No. 3, p. 415). — The bacterium which imparts to 

 butter the peculiar agreeable aroma is described. The experiments on the practical 

 application of this bacterium have not yet been concluded. — p. fireman. 



Comparative study of the bacterial flora of Russian-Swiss and Emmen- 

 thaler cheeses, Budinov (Messenger Imp. Russ. Soc. Acclim. Animals ami Plants, No. 

 11, pp. 15-38; abs. in Zhur. Opuitn. Agron. [Jour. Expt. Landw.~\, 5 (1904), No. 3, p. 

 414)- — Results of 3 complete analyses are given of two Russian-Swiss cheeses (one 

 young and one 3 years old) and one Emmenthaler cheese. In the young Russian- 

 Swiss cheese were found 3 species of bacteria (2 cocci and 1 bacillus), and in the 

 Emmenthaler 6 (3 cocci and 3 bacilli). The rind proved to be in both cases poorer 

 in bacteria than the cheese itself. The 3-year-old cheese was found entirely sterile. 

 All the bacteria isolated were lactic-acid formers and are facultative anaerobic organ- 

 isms. — P. FIREMAN. 



Contributions from Dr. Johan-Olsen's dairy bacteriological laboratory, 

 G. Troili-Peterson (Nord. Mejeri Tidn., 19 (1904), No. 23, pp. 305, 306). —A descrip- 

 tion of the method of pure yeast culture of Johan-Olsen used in the manufacture of 

 the Norwegian cheeses Gammelost and Pultost. — f. w. woll. 



The manufacture of dried milk, R. Crowe (Jour. Dept. Agr. Victoria, 2 (1904), 

 No. 9, pp. 934, 935). — The manufacture of dried milk on an experimental scale by a 

 local firm is described. It is said that the resulting milk powder may be mixed with 

 water and used in the same way as ordinary milk. 



Milk powder; a new industry, II. Vanderyst (Rev. Gen. Agron. [Louvain~\, 13 

 (1904), No. 5, pp. 233-239). — A summary of data regarding the manufacture of dried 

 and powdered milk. 



State milking- courses of 1903, and what they have taught us, O. L. 

 Danils (Nord. Mejeri Tidn., 19 (1904), No. 12, pp. 152-154).— The beneficial effects 

 of the milking courses conducted during the year 1903, which were arranged for by 

 the Swedish government, are commented upon. — f. w. woll.

VETERINARY SCIENCE AND PRACTICE. 



Report of the State veterinarian, L. Pearson (Pennsylvania Dept. Agr. Rpt. 

 1903, pp. 87-158). — The work of the office of the State veterinarian for 1903 is outlined 

 in considerable detail. Copies are given of acts of the Pennsylvania legislature 

 encouraging the repression of tuberculosis and preventing the spread of rabies. 



A condensed statement is presented regarding the present status of glanders, 

 anthrax, blackleg, hemorrhagic septicemia of cattle, rabies, forage poisoning of
