Orig., 7 {1910), No. J,, pj). 4OS-J1 13). —The results show that neither the toxins 

 of fresh bovine, human, or rabbit-sheep serum, nor ana phylaxy toxin produce 

 typical anaphylaxis. These substances were not capable of producing a bron- 

 cho-spasm, but on the contrary brought about an edema of the lung instead. 

 The toxicity of these sera is probably due to an alteration of the coagulation 

 function of the blood, and eventually results in the clTimping of the erythrocytes, 

 with thrombus formation in the alveoli of the lung tissue. 



The antiti-yptic, isolytic, and heterolytic power of the blood serum in 

 different pathological conditions, G. FiNzi (7^cc. Jilccl. Vet., 87 (1910), No. 15, 

 pp. 515-525). — A study of the antitryptic, isolytic, and heterolytic power of the 

 blood serum from animals infected with the tubercle bacillus (cattle), the 

 Preisz-Nocard bacillus (sheep), and others having chronic enteritis (cattle), and 

 from cachectic animals (cattle). 



The results show that with tubercular bovines the antitryptic power of the 

 serum is generally less than that of the normal serum. This is not the case 

 with man. In the case of the Preisz-Nocard infection and chronic enteritis, the 

 index is also lowered. In cachectic animals the index is increased, but this 

 is not directly due to the cachexia present. The hemolytic (heterolytic and 

 isolytic) power was of no clinical value. 



Immunizing agents and therapeutic sera in veterinary medical practice, 

 W. H. Dalkymple (Aincr. Yd. Rev., 38 {1911), No. //, inh 511-511).— A general 

 discussion of the subject. 



About a method of drying serum, S. Frankel and A. Elfer (Biochem. 

 ZtscJir:, 28 {1910), No. 3-//, pp. 330, 331).— The method is described in detail. 



The part played by chemical synthesis in the development of chemotherapy 

 {Osterr. Cliem. Ztg., 13 (1910), No. 21, pp. 263-265).— A review of the existing 

 chemical patent literature, with particular reference to the development of 

 chemotherapy. 



Ehrlich's chemotherapy — a new science, II. Schweitzer (Science, n. scr., 

 32 (1910), No. 832. pp. 809-823) .—After briefly discussing the various tropical 

 diseases of man and animals, particularly those caused by protozoa and their 

 treatment with coal-tar jiroducts, the author with the aid of structural formulas 

 points out the chemistry of the various products used for the above diseases, 

 especially No. GOG for the treatment of lues. 



A description of the Ehrlich-Hata preparation 606 (Ztsclir. Rieeh u. Gesch- 

 maclcst., 2 (1910), No. 24, pp. 267-269; Dcut. Eled. Wchnschr., 36 (1910), No. 

 37, pp. 1693, 1694). — This is the patent specification of Ehrlich-PIata preparation 

 606, which is entitled Methods for Preparing the Amido Derivatives of Oxy- 

 arylarsic Acid and their Reduction* Products. The preparation is chemically 

 dioxydiamidoarsenobenzol. 



About an endotoxin of the Micrococcus melitensis, P. N. Bernard (Compt. 

 Rend. Soc. Biol. [Paris], 69 (1910), No. 24, pp. 36-38; abs. in Ztschr. Immnni- 

 idtsf. u. Expt. Ther., II, Rcf., 3 (1910), No. 3, p. 609).— The author was able 

 to produce a toxin in cultures of M. melitensis which possessed a strong affinity 

 for nerve cells. Intracerebrally it was lethal in from 6 to 9 hours and in- 

 traperitoneally in from 13 to 36 hours. The toxins resisted heat up to 58° C, 

 but at 80° became somewhat weakened. Intracerebrally one one-thousandth 

 part of the dose which is necessary intraperitoneally is fatal. 



The precipitin reaction in erysipelas, A. Vanney (Conipt. Rend. 80c. Biol. 

 IParis], 69 (1910), No. 26, pp. 138, 139; ahs. in Ztschr. Immunitdtsf. u. Expt. 

 Ther., II, Ref., 3 (1910), No. 3, p. 614).— The author was able with filtrates 

 from the erysipelas bacterium and the corresponding immune serum to obtain a 

 precipitation such as Vallee obtained with the serum from horses immunized 

 against tuberculosis and tuberculin. The reaction is most definite at 37° O. and
