{1912), No. 11, p. 111). — This is a critical study of tlie morphology and biology 

 of Bacillus ahortus, the patho-anatomical changes which are present in abort- 

 ing bovines, the avenues of infection, and the occurrence of anti-substances 

 in the blood of spontaneously and artificially infected animals, with particular 

 reference to active and passive immunity. 



It is shown that the production of agglutinins and amboceptors in artificially 

 infected animals is variable, and that much depends upon the method of intro- 

 ducing the vaccine and whether dead or living organisms are employed. Experi- 

 mental data are also presentetl in regard to the behavior of chemical and thermal 

 agencies against the immunizing and anti-substances. In addition some im- 

 munizing and protective tests with rats and mice are reported, which show 

 that spotted rats acquire a decided immunity against this organism when 

 treated with killed cultures or culture filtrates of Bacillus ahortus. 



Therapeutic tests with curative lymph. (Gans) and colpitol (Gans) for 

 contagious vaginal catarrh in bovines, A. Gohler {Ccntbl. Bakt. [etc.], 1. 

 Abt., Orirj., 65 (1012), No. 6-1, pp. 515-538). — Gans' curative lymph was foimd 

 to have only a slight curative power for this disease. Colpitol, on the other 

 hand, affected cures in 30 per cent of the cases, and in all instances where em- 

 ployed improvement was noted in from 16 to 18 days. 



Check list of helminths parasitic in cattle, R. T. Leipeb {Jour. London 

 School Trop. Med., 1 {1912), No. 2, pp. 115-123).— K systematic list of the 

 helminth parasites of Bos taurus, Biiffelus indicus, and Bihos indiciis is fol- 

 Tiowed by an alphabetical list of helminths in cattle and a second list of new 

 genera and species of helminths recorded in 1911. 



The introduction of air into the jugular vein, F. Chambers {Vet. Jour., 

 68 {1912), No. Jifi5, pp. Ifl5, 416). — The author reports experiments made to 

 determine the minimum quantity of air which will kill a bovine when injected 

 into the jugular vein. In the first case, a heifer 3 years old, it took 2,346 cc. 

 of air administered in 12 minutes to cause death; in the second case, that of 

 a 2-year old ox, it took 2,500 cc. of air injected in a period of 4i minutes to 

 cause death ; in the third case, that of 5-year-old cow, 3,000 cc. of air ad- 

 ministered quickly caused the death of the animal in 1 minute. 



Successful vaccination against pluriform septicemia in sheep, Anders 

 {Berlin. Tierdrzil. Wchnschr., 28 {1912), No. 38, pp. 101, 102).— In certain 

 districts in Germany quite a number of deaths in lambs occurred as a result 

 of pluriform septicemia. Vaccinations were made with Miessner and Schern's 

 serum in 1908, 1911, and 1912, and these reduced the mortality considerably. 

 Out of 700 4-week-old sheep, which were vaccinated intravenously in 1912, 

 only 10 died. 



Antisheep pox vaccination with heated virus, E. Ducloux {Compt. Rend. 

 Soc. Biol. [Paris], 12 {1912), No. 16, pp. 109, 110; abs. in Ztschr. Immunitdtsf. u. 

 Expt. Thcr., II, Ref., 6 {1912), No. 1, pp. 380, 382).— Continuing the work pre- 

 viously noted (E. S. R., 27, p. 583) results are now reported which were ob- 

 tained with 6.50 sheep. Of these animals 590 were treated with 0.5 cc. of heated 

 virus, followed 7 days later by an injection of virulent virus, and the remaining 

 60 animals kept as controls. 



Of the treated animals 582 showed no reaction toward the injection, 7 

 showed a slight growth at the site of injection, and 1 had a slight edema. Of 

 the control animals 56 were markedly affected with the pox. 



The method of preparing the vaccine has been slightly modified. 



Congenital bronchial strongylosis in sheep, Neveu-Lemaire {Compt. Rend. 

 Acad. Sci. [Paris], 15J, {1912), No. 20, pp. 13tl, 2312).— The author records 

 observations of the occurrence of adults of Dictyocaulus filaria in 2 young 

 lambs in which the infestation must have taken place prior to birth.
