Further investigations in regard to the optimal media for the after cul- 

 ture in testing disinfectants, K. Supfle {Arch. Hug., 87 {1018), No. 5-4}, pp. 

 2S2-2SIf). — Continuing the investigation by Siiptte and Dengler previously noted 

 (E. S. R., 35, p. 279), the author lias found the optimal media for obtaining 

 after cultures of the streptococcus, diphtheria, and colon bacilli to be 1 per cent 

 glucose bouillon with the addition of 5 per cent serum. 



The starch iodin reaction and its use in colorinietric protein determina- 

 tions in immunity processes, C. Lange {Biochem. Ztschr., 95 {1919), Xo. 1-2, 

 pp. .',6-8ji; (lbs. in Zentbl. Biochem. u. Biophijs., 21 {1919), No. 6, p. 296).— The 

 author discusses the possibilities of the starch iodin reaction for determinuig 

 by colorinietric methods the amount of proteins in a solution such as blood 

 plasma or serum and the application o'f the method to the standardization of 

 bacterial vaccines and to the analyses of immunity reactions. In experiments 

 with dogs it has been shown that the injection of various bacteria is followed 

 by an increase of proteins in the total plasma parallel with the increase in the 

 agglutination titer. 



Field observations in the control of abortion disease, G. M. Potter {Jour. 

 Amer. Vet. Med. Assoc, 57 {1920), No. 2, pp. 152-160).— Thin paper consists of 

 a report of an educational campaign which is being conducted under the 

 auspices of the extension division of the Kansas State Agricultural College 

 for the control of abortion according to the plan previously noted (E. S. R., 40, 

 p. 86). The general plan is reviewed, and observations made in connection 

 with the campaign are noted. Among the points discussed are the immunity 

 conferred by the disease as noted in the spontaneous subsidence of the dis- 

 ease, the tendency of offspring of naturally resistant mothers to inherit the 

 same resistance, the transmission of the disease by ingestion of fresh dis- 

 charges from cows that have aborted, and the natural period of incubation, 

 which has been shown to be from three to five months. 



The author states in conclusion that the greatest progress in the investigation 

 and control of abortion can come only by a combination of laboratory investiga- 

 tion and field work. 



The efficacy of normal sera in anthrax infection, F. V. Hutyua and R. 

 Manningee {Centbl. Bakt. [etc.], 1. Abt., Orig., 83 {1919), No. 7, pp. 518, 519; 

 abM. in Jour. Amer. Vet. Med. Assoc, 57 {1920), No. 2, p. iS8).— The authors 

 report that normal horse, cow, and sheep sera have failed to protect rabbits 

 against artifical anthrax infection, while the sera of horses and cows immunized 

 against anthrax protected control animals. 



Protective results obtained by other authors in the use of normal sera are ex- 

 plained on the ground that the animals furnishing such sera must have 

 acquired a certain degree of immunity through feeding in infected pastures. It 

 Is suggested that this phenomenon probably occurs more frequently in the 

 badly infected regions of Argentina tban in Europe. 



Botryomycosis, J. M'Fadyean {Jour. Compar. Path, and Ther., 32 {1919), 

 No. 2, pp. 73-89, figs. 11). — This paper deals with the niorphologj- of the bdtryo- 

 myces granules. Identity of the Botryococcus and the Staphylococcus pyogenes 

 aureus, botryomycosis in other species than the equine, and the lesions of 

 botryomycosis. A list is given of 15 references to the literature. 



Contribution to the determination of the value of polyvalent extracts 

 for the serum diagnosis of glanders by the complement deviation reaction, 

 including observations on the disappearance of glanders-specific deviating 

 substances, W. Pfeileb and F. Gkafe {Centbl. Bakt. [etc.], 1. Abt., Orig., S3 

 (1919), No. 6, pp. 451-^56).— J>:e\v evidence is furnished that polyvalent extracts 

 are preferable to monovalent for the diagnosis of glanders by the complement 

 deviation method previously noted (E. S. R., 42, p. 272). The case reports
