 reliitin? to this question in connectiuii with a l)il)liu};riii)liy uf s:; titles. In 

 testing the virulence of tubercle bacilli of different origin, resort is usually had 

 to the subcutaneous, intravenous, and intraiieritoncil methods of inoculation. 

 The author chose the method of injection into the uddi r without jiroducing any 

 lesion. In these experiments three cultures were used, two of hvu)ian and one 

 of bovine origin. The two cultures obtained from consumptive human patients 

 failed to produce tuberculosis when injected into the udder of cows, and calves 

 which drank the milk also remained healthy. The bovine tubercle bacilli, 

 however, produced a general infection which involved not only the udd(M- but 

 various other organs and tissues and caused infection in the calf which drank 

 the milk. 



Tuberculosis of the male genital organs of cattle. .T. Kowai.ewskv (Rrr. 

 G(hi. MM. 1V^. 7 {1!)06). A'O. 80, pp. .'/ 17 -', 19). —It is stated that in Moscow, 

 tuberculosis of the male genital organs of cattle was only observed in 1 cas(> out 

 of 74,380 which were inspected at slaughterhouses, Onaccoxuit of the unusunl 

 rarity of this form of tuberculosis the author gives detailed notes on two casws 

 wliich came inider his observation. 



Tuberculin tests, X. O, Nielsen ( Maaiirflskr. Dyrhr</cr. IS (IDIIG). A'o. /, 

 /)/). 20~.>.')). — The author undertook the ai)plication of the tuberculin test in his 

 neighborhood for the purpose of determining the extent of infection. The 

 results obtained were very satisfactory in so far as the reliability of the test is 

 concerned. In one locality where 08 hogs were fed on the skim milk obtained 

 from a creamery, 29 were found to be tuberculous. A system of pasteurization 

 of the milk was consequently adopted. 



Tuberculin and the organism, F. Koiiler (Tuhcrl-tilln inuJ Orf/diiisiinii^. 

 Jena: Gusto r Fischer. 100.'). pp. 100). — The extensive tests which have been 

 reported with tuberculin in eow-s of different countries throughout the civilized 

 world have led to differences of opinion regarding the reliability of tuberculin, 

 its use for therapeutic purposes, and other matters connected with the gencn'al 

 problem of tuberculosis. The author has presented in a brief manner a sum- 

 mary fif results obtained by Viirious investigators, the material being arranged 

 under various subheads including chemical investigations, pathology, clinical 

 studies, and therapeutic use of tuberculin. This summary of literature relating 

 to tul)erculin makes it ai)parent that while numerous facts have beeTi worked 

 out with tolerable certainty there still remain many doubtful points for further 

 investigation before positive statements may be made regarding the elTect of 

 tuberculin upon the organism. 



The demonstration of antituberculin and tuberculous tissue, E. Weil and 

 IT. Xak.v.i.vma (Miiiiclicii. Med. Wrhiischr.. .',.] {Willi). .\o. 21. pp. lOOl-lOO.'t).— 

 An attempt was made to determine the specific effect of tuberculin upon tuber- 

 culous tissue, and in these experiments active serum was used after being ren- 

 dered inactive by increasing doses of horse blood. The author believes that the 

 experinients of Wassermann and Bruck proved merely that extractives from 

 tubercle bacilli are found in tuberculous foci. The formation of the complement 

 takes place as a result of a mixture of tuberculin and organic extract. It is 

 believed possible that antituberculin may be present in tuberculous tissue, but 

 this has not been proved. The authon .discards the theory that complement is 

 formed by a chemical affinity between antituberculin and tuberculin. 



The leucocyte and the tubercle bacillus, J. Bartel and W. Neu.mann 

 (Centhl. Bait. \cic.]. 1. Aht.. ()ri</.. )il {lOOG). No. 5. pp. 723-738).— In the e.x- 

 periments reported in this paper the authors made use of guinea itigs, rabbits, 

 and dogs for inoculation, with an intent to deternune the relationship between 

 the leucocyte aud the tubercle bacillus. It appears from these experiments that
