these have previously combined themselves with alexin. Alexin, which is 

 necessary for the conglutinin, is inhibitory for the agglutinin proper. 



The relation of bacterial precipitins to agglutinins, W. Gaeiitgens {Ztsclir. 

 Immunitdtsf. u. Expt. Tlier., I, Oriff., 7/ (J910), No. 5, pp. 55.9-574 ) .—In view of 

 the fact that the precipitins appear in the serum of infected animals before the 

 agglutinins the hypothesis of Kraus, that is " that every bacterial filtrate pre- 

 cipitating serum also agglutinates the homologous bacteria," does not hold 

 good. Therefore, agglutination and precipitation, respectively their antigens, 

 are not identical. 



Are methylene blue and hematoxylin antigens ? M. Takemura (Ztschr. Im- 

 munitdtsf. u. Expt. Thcr., I, Orig., 5 (1910), Xo. 6, pp. 697-699 ) .—Rabbits 

 treated with either methylene blue or hematoxylin showed no formation of 

 antibodies. 



About the passive transference of immunity against rabbit sarcoma, von 

 DuNGERN (Ztschr. Immtinitdtsf. u. Expt. Ther., I, Orig., 5 (1910), No. 6, pp. 

 695-697). — It was possible to transfer the immunity 3 weeks after the vaccina- 

 tion with rabbit sarcoma and through the agency of the serum. 



A disease simulating paresis of pregnancy, S. Laufer (Allatorvosi LapoJc, 



31 (190!^), Xo. .'i3, pp. o26, 527; ahs. in Berlin. Tierdrztl. Wchnschr., 26 (1910), 

 No. 22, p. 'I'l't). — A description is given of a disease which simulates the paresis 

 of pregnancy and occurs in pregnant animals which indulge in too much food 

 and too little exercise before parturition. The treatment which was applied 

 with good success consisted of injecting air into the mammary gland with 

 Ewar's air pump. Recovery was obtained in from 1 to 2 hours. The parturi- 

 tion was normal. 



Obstetrical aid to smaller domestic animals, W. Koppitz (Tierdrztl. Zenthl., 



32 (1909), No. 32, pp. 506-508; ahs. in Berlin. Tierdrztl. Wehnselir., 26 (1910). 

 No. 22, p. Jf.'i4). — On the basis of experiments the author recommends manual 

 obstetric aid for small domestic animals. The disadvantages of the obstetric 

 forceps are pointed out. 



Diagnosis of blackleg, Foth (Ztschr. Infektionskrank. u. Hyg. Haustiere, 6 

 (1909), No. 3-.'i, pp. 201-255, figs. 2). — As a result of post-mortem, pathological, 

 and bacteriological findings, the author concludes that symptomatic anthrax can 

 be diagnosed with certainty on the basis of the bacteriological findings, particu- 

 larly in cases where doubt exists after making the usual post-mortem examina- 

 tion. Particular attention is directed to the i^athological appearances as they 

 are described in the average meat inspection text-book and the appearances as 

 noted in the actual examination. 



Anticharbon serum therapy, L. Boidin (Prcsse Med. [Paris], 1910, No. Jf2, 

 pp. 393-395). — A general consideration of this subject, that is, preventive and 

 curative serum therapy, and the mode of action. 



The agglutination test in glanders, Nevermann (Berlin. Tierdrztl. 

 Wchnse}n\, 25 (1909), No. 19, pp. 3.'/ 7-350 ) .—Results of agglutination tests car- 

 ried out from April 1, 1907, to March 31, 1910, in Prussia with 1.750 horses are 

 reported. Of this number 283 were either killed or died, of which 177 on 

 autopsy were found to be glandered, and 09 were killed for other causes than 

 glanders and not on the basis of the agglutination test. From the work the 

 author concludes that the agglutination test is an excellent aid for the early- 

 diagnosis of glanders, but further that the findings with reference to the 

 agglutination figure can only be compared when the tests are conducted by the 

 same method and with the same standard solution, or those of equal strength. 



Concerning the nature of the parasite of epizootic lymphangitis, J. Bridr^ 

 and L. Negrf (Compt. Rend. Acad. Sci. [Paris], 150 (1910), Nos. 16, pp. 998^ 

 1001 ; 20, pp. 1265-1267). — Deviation of complement studies here reported iudl-
