Investigations in regard to the tuberculosis problem, Lydia Rabinowitsch 

 (Deul. Med. Wchnschr., 39 (1913), No. 3, pp. 103-106; nhs. in Ztschr. Flci-sch u. 

 Milchhyg.. 23 (1913), No. 20, p. ^7^).— On injecting the bile from seventeen 

 tuberculous subjects into guinea pigs, that of twelve produced tuberculosis in 

 these animals. With the antiformin and microscopical methods only one case 

 yielded positive findings, consequently it is concluded that the gall bladder is a 

 source of elimination for the tubercle bacillus and must be reckoned with when 

 dealing with preventive measures for this disease. Six strains of organisms 

 isolate^l were more closely examined, and four belonged to the human and two 

 to the bovine type. The author considers these results as confirmatory of the 

 findings of Schroeder and Cotton (E. S. R., 19, p. 181) and Joest and Emshoff 

 (E. S. R., 20, p. m2). 



The virulence of the tubercle bacilli in the so-called " rayed caseation," 

 Hafemann and Bindkr (Zt.'ivhr. Flci><ch u. Milchhiig., 2S (1913), No. 23, pp. 

 529-531). — A continuation of the work previously noted (E. S. R., 30, p. 882). 

 The tubercle bacilli obtained from the rayed foci were found Ho be very virulent. 



A contribution to the occurrence of primary pudic and vaginal tubercu- 

 losis in the bovine, W. Meyer (Ztschr. Fleiseh u. Milehhyg., 22 (1912), No. 10, 

 pp. 303-306, fly. 1; ah.t. in Centbl. Bait, [etc.^, 1. AM., Ref., 56 (1913), No. 7, 

 p. 201).— \ description of a case, the identity of which was established by vacci- 

 nating rabbits with some of the tuberculous material. Tbis affection as of man 

 is rarely observed in animals. 



The diagnosis of tuberculosis with the anaphylactic test in vitro, A. Tadini 

 (Pathologica, Jf (1912), No. 98, pp. 719-721; ahs. in ZUehr. Immunitatsf. u. 

 E.vpt. Thcr., II, Ref., 6 (1913), No. 15, p. 1112).— By injecting into a rabbit a 

 mixture from a tuberculous sul)ject consisting of tuberculin and serum which 

 has been kept in the incubator for two hours, or a control injection of normal 

 serum and tuberculin, no anaphylactic phenomena were ever noted. Likewise 

 no effect was produced by injecting normal or tuberculosis serum alone into 

 rabbits, except in two animals, one of which received tuberculosis serum and 

 the other a normal serum, and which is explained as due to the toxicity of the 

 serum. A passive conveyance of anaphylaxis from a tuberculous subject to an 

 animal is not deemed jiossible. 



The diagnosis of tuberculosis with the anaphylaxis reaction, P. Valenti 

 (Pathologica, 4 (1912), No. 91, pp. Jt88-Jf90 ; ahs. in Ztschr. Immunitatsf. u. 

 Expt. Thcr., II, Ref., 6 (1913), No. 15, p. 1110).— The results were very satis- 

 factory when conducted by a procedure different from that of Yamanouchi's. 

 Further tests should be made with it, however, in order to determine Its value 

 as a diagnostic agent. 



The thermoprecipitation reaction in tuberculosis, A. Fagiuoli (Pathologica, 

 4 (1912), No. 89, pp. JflO, Jfll; abs. in Ztschr. Immunitatsf. u. Expt. Ther., IT, 

 Ref., 6 (1913), No. 15, p. 1112). — The sputum was mixed with physiological salt 

 solution, boiled, and then filtered through asbestos, or the extract was mixed in 

 the cold with concentrated acetic acid, neutralized, and filtered through a 

 bisque filter and paper. The specific serum used was Vallee's. The layer test 

 was characteristic but it was not specific for tuberculous subjects. 



A reaction was obtained also with sputum from subjects affected with pneu- 

 monia and simple bronchitis. 



Tuberculous antigens and antibodies. — Inhibition reaction, A. Calmette 

 and L. Massol (Compt. Rend. Soc. Biol. [Paris], 75 (1913), No. 28, pp. 160, 

 161). — By introducing a stream of carbon dioxid into an inhibiting serum 

 diluted 1 : 10 with distilled water, a precipitate is obtained which shows precipi- 

 tating and inhibiting properties greater than those of the original serum. On 

 the other hand the serum, after removal of the precipitate, while robbed of
