380 EXPERIMENT STATION RECORD. 



Secondary and tertiary cholera substances are capable of binding immune 

 substances; cholera-precipitates, on the other liand, do not possess any binding 

 capacity for noi'mal serum. 



Tlie cause of natural immunity in pneumonia, Vl Ungermann (Arl). K. 

 Gsnaiitsamt., 36 (1911), No. 3, pp. 341-357).— It is concluded that normal re- 

 sistance against pneumonia is due to the phagocytic power of the fresh normal 

 serum. 



Studies in reg-ard to tlie complement binding phenomena in hemorrhagic 

 septicema, T. Matsuda (Ztschr. Jlyfi. u. Iiif('L-fion..^krank., 66 (1910), NfK 3, 

 pp. 383-392). — This is in part a verification of the work of Wassermann, Citron, 

 and Piitz." 



From the results it is noted that after a single infection the blood serum is 

 so changed that in conjunction with the antigen it inhibits hemolysis. Further- 

 more, it is seen that it is possible with the method to differentiate the individual 

 members of the septicemia group. 



Treatment of Purpura hemorrhagica with streptolytic serum, J. J. Joy 

 (Amer. Vet. Rev., 38 (1911), No. J/, pp. 539. 5f,0).—The author with 30 cases of 

 this condition and serum had quicker and cleaner recoveries than with the old 

 line treatment. The histories of 3 cases are appended. 



Differentiation of the meningococcus from similar organisms by the 

 peritoneal test, C. Dopter (Conipt. Rend. 8oc. Biol. [Parish, 69 (1910), No. 

 38, pp. 600-602). — The test is based on the reaction of Pfeiffer, and was made 

 with the true meningococcus, the pseudomeningococcus, and the gonococcus. 



The action of spennotoxins upon the female organism and the egg, M. P. 

 TusHNoV (Ziehen. Zap. Kazan, Vet. Inst., 21 (1910). No. 1, pp. 29-31; ahs. i/n 

 Ztschr. Immunitatsf. u. Expt. Ther., II, Bef., 3 (1910), No. 7, p. 820).— The 

 author reports the fact that he was able to immunize actively rabbits with 

 sperma-spermotoxiu, and thus produce sterility. 



Report of the Bombay bacteriological laboratory, W. B. Bannegman 

 {Rpt. Bombay Bact. Lab. 1909, pp. 19). — A report of the activities of the 

 laboratory for the year 1909. It has particular reference to the control of 

 plague and gives statistics in regard to vaccination against this malady. 



Clinical results with bacterial vaccine, F. E. Barnes (Amer. Vet. Rev., 38 

 (1910), No. 3, pp. 392, 393). — A report of 10 cases, among which were poll evil, 

 quittor, and fistula, and which were successfully treated with antisuppuration 

 bacterial vaccine. 



The action of Bacillus coli on the animal organism, J. Studzinski (Compt. 

 Rend. Soc. Biol. [Paris], 70 (1911), No. 7, pp. 225-227).— In this preliminary 

 note the author states that after giving B. coli subcutaneously, intravenously, 

 intraperitoneally, and per buccal cavity, lesions could be noted in the liver and 

 kidneys. The gross and microscopic characteristics are stated in detail. 



Investigations in regard to the serum of sheep infected with the Preisz- 

 Nocard bacillus and that of cachetic horses, G. Finzi (Compt. Rend. Soc. 

 Biol. [Paris], 69 (1910), No. 25, pp. 6Jf-66; abs. in Ztschr. Immunitatsf. u. 

 Expt. Ther., II, Ref., 3 (1910), No. 3, p. 599).— The antitryptic property in the 

 serum of a sheep infected with the Preisz-Nocard bacillus is almost always 

 uniformly diminished, and where • caseous suppuration exists the antitryptic 

 index is always lower. No benefit therefore can be expected by noting the 

 variations in the hemolytic capacity of the serum for detecting tuberculosis,
