584 EXPERIMENT STATION RECORD. tVol. 43 



tubercle bacilli injected by the use of a standard suspension in salt solution. 

 Tlie injections were made subcutaneously instead of intramuscularly. 



From tlie results reported, the conclusions are drawn tliat a specific solution 

 of tubercle bacilli in a tuberculous organism does not take place, that the 

 biological method for the differentiation of acid-fast bacteria is not reliable, 

 and that the importance of bacteriolysis in tuberculosis immwnity has not yet 

 been proved. 



Benzyl alcohol in experimental tuberculosis (in vitro), J. .Jacobson 

 (Compt. Rend. ,Soc. Biol, [/'(/r/.s], 82 (1919), No. 31, pp. 126J,-126G).— The 

 author reports that benzyl alcohol has the power of dissolving tubercle bacilli 

 and of rendering them less easily stained by fuchsin. Subcutaneous injection 

 of 0.02 gm. of benzyl alcohol into tuberculous rabbits was found to cause no 

 local or general reaction. 



Chemotherapy of tuberculosis with potassium cuprocyanicl, C. Hollanue 

 and J. GATfi (Compt. Rend. Soc. Biol. [Par/.s], S3 (1920), No. 7, pp. 17S-180).— 

 Potassium cuprocyanid lias been found to have properties similar to those of 

 the cyancuprol of Koga (E. S. II., 36, p. 27S). In weak doses it has no bac- 

 tericidal action on the tubercle bacillus. In the experimental tuberculosis of 

 guinea pigs, it first causes congestion aroinid the lesion and then a tendency 

 to form granular tissue. 



The present status of tuberculosis treatment with partial antigens of 

 Deycke-Much, K. Klare (Tnteruatl. Centbl. Gesatn. Tuberkulose Forsch., H 

 (1920), No. 1, pp. 4-16). — A review of tlie literature from 1907 to 1919, includ- 

 ing 119 references. 



Infectious abortion in cattle. — II. Specific measures of control and ulti- 

 mate eradication, G. C. White and L. F. Rettgeb (Connecticut Storrs Sta. 

 Bui. 103 (1919), pp. 139-150, figs. 5). — This second contribution to the subject 

 (E. S. R., 39, p. 491) discusses the rOle of the bull as a carrier of tlie infection 

 and the manner of control by disinfection. The authors recommend the use 

 of a 1 per cent solution of cresol. The sheath should be disinfected by use 

 of a continuous flow suction and injection pump with rubber tube attached. 



The control of contagious bovine pleuropneumonia in French Senegal, 

 L. Teppaz (Rec. MM. Vet., 95 (1919), No. 21, pp. 611,-617; abs. in Trop. Vet. 

 Bui., S (1920)* No. 1, pp. 57, 58). — The method employed in Senegal for com- 

 bating pleuropneumonia in cattle consists in vaccinating all of the cattle in 

 infected herds with material from the lungs of an affected animal slaughtered 

 for the purpose or which had died within six hours. The inoculations are 

 made at the tip of the tail or on the forehead, three incisions being made. 



It is reported that 15,400 cattle were thus vaccinated in 1918, and 6,817 

 during the first half of 1919. 



Malignant catarrhal fever of cattle in Kansas, L. W. Goss (Vet. Notes, 

 13 (1920), No. 2, pp. 29-31). — Tlie author records the occurrence of this disease 

 on several farms in Kansas. In one herd of 30 grown animals, all of which 

 were affected, 5 succumbed and 1 aborted. None of the calves was affected. 

 In none of the herds was there afty indication that the disease was trans- 

 mitted from one animal to another. In two places the opportunity for trans- 

 mission was excellent, if it is a transmissable disease. In most of the herds 

 it seemed that the onset was sudden and the recovery slow. After the trouble 

 developed, the feeds were changed and there was no recurrence. 



A note on the treatment of surra in camels hy intravenous injections of 

 tartar emetic, H. E. Cross (Af;r. Research Inst. Pusa Bui. 95 (1920), pp. 6).— 

 Experiments reported led to the conclusion that a number of camels were 

 cured, and that tartar emetic gives promise of success in the treatment of 

 surra.
