182 EXPERIMENT STATION RECORD. 



Further investigations on cheese, P. Buttenberg and W. Koenig (Ztschr. 

 L'niersuch. Xahr. u. Genussmtl., 19 (1910), \o. 9, pp. ^75-48-J). — Analyses are 

 reported of Chester, Parmesan, Kiinmiel, Brie, Sahnenschicbt, Roniadour, Mar- 

 garin and many other varieties of European cheeses. The methods of making 

 the analyses are described. 



Dairy products of Montenegro, O. Laxa {Rei\ Gen. LaU., 8 {1910), Nos. 8, 

 pp. 179-186; 9, pp. 201-207, pis. 2). — An -account of the dairy industry in Monte- 

 negro. Some cows are kept but the domesticated animals are chiefly sheep 

 and goats. 



One of the principal dairy products of the Balkan countries is skorup, which 

 is made chiefly from the milk of sheep. The milk is heated and poured into 

 elliptical wooden vessels, where it remains from li to 2 hours. The top layer 

 is removed and constitutes the skorup, which may be eaten fresh on potatoes 

 and other foods. A large projiortion of the skorup is salted and placed in casks, 

 where it undergoes some fermentation, yielding a product intermediate between 

 butter and cheese. In taste it resembles cream cheese, but varies according to 

 the degree of rii)eness. In case it is infected with molds it is much like Roque- 

 fort cheese in taste and smell. In analyses of samples obtained in different 

 places the percentage of dry matter ranged from 70 to 85 per cent, fat from 50 

 to 76 per cent, albuminoids from 5.57 to 14 per cent, and ash from 1.28 to 5.87 

 per cent. 



The native methods of making butter, cheese, and several kinds of fermented 

 milks are described. 



VETERINARY MEDICINE. 



Animal experimentation: The protection it affords to animals themselves 

 and its value to the live-stock industry of the country, X. A. Mooke (Jour. 

 Amer. Med. Assoc, 54 (1910), No. 11, pp. 85-i-S59). — The great importance of 

 animal experimentation, particularly as related to the development of our 

 knowledge of contagious pleuro-pneumonia of cattle, glanders, rabies, anthrax, 

 Texas fever, tuberculosis, hog cholera, etc., is discussed at some length. 



On the distribution of antibodies and their formation by the blood, L. 

 Hektoen and A. J. Carlson (Jour. Infect. Diseases, 7 (1910), No. 2, pp. 319-333, 

 charts 5). — Experiments conducted with dogs are reported. 



Agglutination and sero-reaction in mycoses, F. Widal et al. (Ann. Inst. 

 Pasteur, 24 (1910), No. 1, pp. 1-33; ahs. in Jour. Amer. Med. Assoc., 54 (1910), 

 No. 14, p. 1174)- — '* It seems evident from the research and experience reported 

 that it is possible to differentiate actinomycosis by agglutination and the fixa- 

 tion of complement test using for the purpose spores of the Sporotrichum ; the 

 actinomyces does not resi)ond to the tests, but there is a generic reaction with 

 the spors of the allied Sporotrichum. The latter can be easily cultivated and 

 separated. The reactions also occur constantly in thrush with these spores, but 

 there is no reaction in ringworm or aspergillosis." 



On the variation of the hemolytic complement in experimental trypano- 

 somiasis, W. YoRKE (Ann. Trap. Med. and Par., 3 (1910), No. 5, pp. 565-579). — 

 From experiments conducted and here reported in detail the following conclu- 

 sions have been drawn : 



"The results obtained confirm those of Hartoch and Yakimoff, that in most 

 cases of experimental trypanosomiasis, a marked diminution or total disappear- 

 ance of the hemolytic complement can be observed for a few hours before 

 the animal's death. This decrease of the hemolytic complement is limited to 

 the last stages of the disease, and is not met with in the earlier stages, even 

 when the blood is swarming with trypanosomes. The serum of an animal in
