384 EXPERIMENT STATION EECORD. 



In regard to accidents occurring during vaccination, E. Leclainche (Rev. 

 G^n. M6d. V^t., 18 (1911), Wo. 209-210, pp. 262-211).— The author here reports 

 the deaths ot pigs which were traced directly to the vaccine used for protecting 

 against hog erysipelas. The constitutional condition of the animals had much 

 to do with the mortality. 



New experiences with equine influenza, Rips (ZtscJir. Veterindrk., 22 

 (1910), No. 11, pp. 505-509; abs. in ZiscJir. Immunitdtsf. u. Expt. Thcr., II, Rcf.. 

 3 (1910), No. 8, p. 8Jf/f). — Attention is drawn to the fact that in some cases a 

 petechial fever occurs with this disease in horses. The author points ont that 

 he was able to cope with this disease in 2 cases by using antistreptococcic 

 serum (Gans). 



The cause of equine influenza, J. Basset (Compt. Rend. Acad. Sci. [Paris], 

 153 (1911), No. 8, pp. //85-//S7). — Equine influenza (pinlj eye, pasteurellosis; 

 Ligniere's, contagious pleuro-pneumonia, etc.) according to this investigator is 

 produced by a filterable virus. He was able to reproduce this disease in 3 

 horses by inoculating the defibrinated blood, and in some instances the filtered 

 blood, obtained from a typical case of this disease. 



Equine piroplasmosis, A. Pricolo (Clin. Vet. [Milan'], Rass. Pol. Sanit. e Ig., 

 3-'f (1911), No. 20-21, pp. 915-940). — A summarized account, with a bibliography 

 of 43 titles. 



On Gastrodiscus aegyptiacus and Spiroptera megastoma, Bebk^ (Centhl. 

 Bald, [etc.], 1. AM., Orig., 58 (1911), No. 2. pp. 129-lS-',. fig. i).— The author 

 describes the case of a Kamerun horse which was reduced to extreme emacia- 

 tion by large numbers of trematodes (G. wgyptiacns) and nematodes (S. megas- 

 toma) in the stomach and intestines. 



Septic arthritis in foals, Stevens and Smead (Amer. Vet. Rev., 39 (1911), 

 No. 5, pp. 556-559). — The treatment of septic arthritis resolves itself into 2 

 phases, the prophylactic and curative. The greatest stress, according to the 

 author, must be laid upon prophylaxis. Both methods are described in detail. 



Blackhead (infectious entero-hepatitis or typhlo-hepatitis) : A disease of 

 young turkeys, W. Jowett (Agr. Jour. Union So. Africa, 2 (1911), No. 5, pp. 

 612-617). — The author states that up to the present time he has met with this 

 disease in turkeys only in Capetown and the Western Province. The disease 

 was apparently introduced into one flock examined, by turkeys imported from 

 America. 



RURAL ENGINEERING. 



Experiments with oil burning in boiler furnaces, E. W. Kerr and H. A. 

 Nadler (Louisiana Stas. Bnl. 131, pp. 3-61, figs. 7). — Inasmuch as fuel losses 

 in sugar factories are considered to be as often due to inefficient oil burning as 

 to inefficient bagasse burning, the authors conducted boiler tests with oil which 

 are reported, as well as a comparison of oil and bagasse burned together and 

 separately. 



" The average equivalent evaporation of water per pound of oil in tests 

 where conditions were regulated to give best results, including 11 out of 23 

 tests, was 1-5.53. This is excellent practice. 



" The average equivalent evaporation of water per pound of oil with the dif- 

 ferent forms of settings experimented upon were so nearly the same as to jus- 

 tify the conclusion that the different settings were practically equal in their 

 efficiencies as regards evaporation. . . . The above conclusion adds weight to 

 the contention that combustion chamber volume is the principal requirement 

 for efficiency. . . . 



" In the tests to determine the relative merits of burning oil in the same 

 furnace with bagasse and in specially designed oil furnaces separate from
