Immunization of goats against Malta fever, II. Vincent and Collignon 

 (Compt. Rend. Soc. Biol. [Pans], 69 (1910), No. 3f,, pp. //68-470).— Results of 

 tests with the vaccine prepared by the author (by talking an emulsion, in 

 physiological stilt solution, of a 3-day-old gelathi culture of Micrococcus 

 melitensis and treating it with ether and agitating, then evaporating off the 

 ether and heating at 38° C.) on young goats are reported. The results ob- 

 tained were considered good. 



Some recent experiments on infectious anemia of tlie horse, M. Francis 

 and R. P. Marsteller (Amcr. Vet. Rev., 39 {1911), No. 2, pp. 132-lJf7).—This 

 is a report of studies conducted in continuation of those reported in Bulletin 

 119 of the Texas Station, previously noted (E. S. R., 20, p. 1084). 



A horse, which was kept for 2 years in a small iiasture with several in- 

 fected horses and mules, did not become infected, although it ate from the 

 same manger, drank from the same trough, and grazed witli them. At the 

 end of 2 years the horse was injected with 3 cc. of blood from an infected 

 mule, a high fever developing on the twelfth day and again on the twenty- 

 third day, which proved fatal. 



In a second experiment 4 oz. of blood drawn from the jugular vein of the 

 horse mentioned above and given by mouth to a healthy horse on November 

 26 produced the disease but did not prove fatal. Four oz. of blood drawn on 

 January 10 from the animal infected November 26 just at the close of the fifth 

 reaction and injected into a healthy hor.se caused its death on April 10. Four 

 oz. of blood from the horse which died April 10 was given by mouth on March 

 25 to another horse but failed to infect. 



In a tliird experiment large numbers of larvfe of the cattle tick (Margaropus 

 [Boophilus] annulatus), the progeny of females which engorged on an in- 

 fected horse, were applied and attached to an uninfected horse but failed to 

 produce the disease. In a fourth experiment bisulphate of quinin administered 

 by mouth to a 10-year-old mule appeared to arrest the faver. In a fifth ex- 

 periment atoxyl was administered but failed to be of value. In a sixth experi- 

 ment a 12-year-oId mare tliat was subcutaneously inoculated Avith 15 cc. of 

 porcelain-filtered blood from a mule the blood of which was known to be 

 virulent, developed the disease; trypanred was then injected intravenously but 

 apparently had no value as a curative agent. In the seventh and last experi- 

 ment here reported the intravenous injection of trypanblue failed to arrest the 

 disease. 



Temperature tables accompany the reports. 



Observations on bursatti [summer or rain sore], C. L. Roadhotjse (Amer. 

 Vet. Rev., 38 (1910), No. 3, pp. 376-382).— The author, after detailing his clin- 

 ical findings with this disease, concludes "that he was successful in treating 

 bursatti by excising the diseased tissues as completely as possible, followed by 

 the application of antiseptic solutions and dusting powders; that strong solu- 

 tions of formaldehyde prove effective in checking the secretions and excessive 

 granulations, without noticeable ill effects to the animal ; and that animals 

 suffering with the extensive forms of the disease can be treated more success- 

 fully by removing them to cool climates where the disease is not apt to recur." 

 In no case were filaria found in the blood. 



Observations upon equine colic, P. Speiseb (Munchcn. Tierdrzth Wchnschr., 

 55 (1911), No. 6, pp. 87-89; ahs. m Vet. Rec, 28 (1911), No. 1190, p. 696).— 

 Among 65 colic cases treated by the author during the year were 6 fatal cases 

 of verminous embolism of the colic arteries caused by Strongylus armatm.
