588 EXPERIMENT STATION RECORD. I Vol. 88 



The technique of the preparation of the polyvalent antipyogenic vaccine Is 

 described in detail. This can be us-ed not only in the treatment of epizootic 

 lymplianj^itis but also in that of various pyogenic lesions in the horse. 



Some typical cases of treatment of epizootic lymphangitis by pyotherapy, 

 Velu (Bui. Soc. Cent. MM. V^t., 93 (1917), No. 2Jt, pp. 5il-52//).— Several cases 

 are described. 



Leucocytotherapy or aseptic pyotherapy, its use in certain lymphangites 

 of the horse, J. Bridk6 {Compt. Rend. Acad. Sci. [Paris], 165 (1917), No. 27, 

 pp. 1121-1123; abs. in Rev. G^n. Med. Vet., 27 (191S), No. 313, pp. 20, 30; 

 Cheni. Abs., 12 (1918), No. 6, p. 593). — The nonspecificity of cryptococcic pyo- 

 vaccine and the efficacy in ulcerous lymphangites of a pyovaccine very poor in 

 microorganisms suggested to the author that the vaccines owed their efficacy 

 not to the specific microbes which they contained but to leucocytes or leucocytic 

 debris and the products derived from them, and that, consequently, the 

 same satisfactory results will be obtained by the injection of an aseptic pus 

 such as is found in a fixation abscess. To test this theory, horses with epizootic 

 and ulcerous lymphangitis were injected with a dilution of pus obtained from 

 u fixation abscess previously produced by subcutaneous injection of essence 

 of turpentine. The liquid was quickly absorbed and generally no trace of the 

 Injection was left. 



The second treatment was in all cases followed by a very rapid cure, thus 

 confirming the author's theory. " Aseptic pyotherapy can be employed advan- 

 tageously in equine lymphangitis and in diseases where pyovaccines have 

 already been satisfactory. It is possible that it is susceptible of a more general 

 application." 



Some considerations on the efficacy and absolute nonspecificity of anti- 

 cryptococcic pyotherapy in the horse, H. Veltt (Bui. Soc. Path. Exot., il 

 (1918), No. 1, pp. 12-17). — Cases are cited from which the conclusion is drawn 

 that polyvalent nonspecific pyotherapy is a simple economical method which 

 by the results already obtained should occupy a position of the first order in 

 therapeutic veterinary practice. 



The necessity of carbon dioxid for the growth of Bacillus tuberculosis, 

 W. B. Whebry and D. M. Ervin (Jour. Inject. Diseases, 22 (1918), No. 3, pp. 

 194-197, fig. 1). — Tests on culture media showing the effect of different carbon 

 dioxid pressures on the growth of B. tuberculosis are reported. The necessity 

 of carbon dioxid and of a supply of free oxygen for growth of the organism on 

 artificial media Is shown. The optimum requirements have not yet been 

 determined. 



An investigation of strains of tubercle bacilli from animal tuberculosis, 

 A. S. Griffith (Jour. Path, and Bad., 21 (1917), No. 3, pp. 329-3^3) .—The 

 investigations here reported relate to the types of tubercle bacilli from naturally 

 acquired tuberculosis in the monkey, cat, goat, bovine, and bird ; the cultural 

 characteristics of bovine tubercle bacilli ; and human tubercle bacilli in the 

 milk of a vaccinated heifer. 



Infectious abortion in cows, K. BtrcHi-i (Meded. Rijksseruminricht., 1 

 (1917), No. 3-4, pp. 121-205, figs. 2).— The author has reviewed the literature 

 on this disease including the history, etiology, biology, and course of the dis- 

 ease ; symptoms and diagnosis ; abortin and its application ; agglutination and 

 complement fixation ; active and passive immunity ; methods of combating the 

 disease; and veterinary laws for controlling it. A bibliography of 68 titles Is 

 appended. 



Mixed bacterial diseases of swine with differential diagnosis, J. D. Reab- 

 DON (Amer. Jour. Yet. Med., IS (1918), No. 2, pp. 57-61).— The author discusses
