Duriii;; the roiirse of the iuvestif^iilion tests were iiiiule of II' liiheirulous 

 boviues by transferring their blood as raiiidly as iMissililc Id ihc pcrilimcal 

 cavities of guinea pigs. The results obtained liave licen sununarizcd as ridlows; 



"We failed utterly to find tubercle bacilli in flic blood of tuberculous cattl(> 

 which we examined microscopically in accordance with the method described 

 and used by Doctor Rosenberger. 



" The negative results of our microscopic examinations are confirmed by 

 the negative results obtained with 95 guinea pigs, each of which received an 

 intraabdominal injection of blood from a tuberculous cow or bull. 



"As the number of cattle from which blood was injected into the 95 guinea 

 pigs was 42, and as these cattle represented practically all stages of tuber- 

 culosis from mildly affected recent cases to old and completely generalized cases, 

 we feel that our work shows beyond the remotest doubt that tuberculosis is 

 not to be classified, in any sense of the word, as a bacteriemia." 



In an appended note mention is made of an independent investigation by 

 Dr. J. R. Mohler, in which the blood of S infected cattle was examined micro- 

 scopically and the blood of each animal injected into fj guinea pigs. Four of 

 the cattle used were slaughtered for meat, but upon inspection were found to 

 be so extensively affected with tuberculosis that it was necessary to condenui 

 and tank their carcasses under tlie Federal meat-inspection regulations. The 

 other 4 were passing tubei'cle bacilli from their bowels. However, no tubercle 

 bacilli were discovered microscopically and not one of the 40 injected guinea 

 pigs contracted tuberculosis. 



Investig'ations of the tubercle bacillus in cattle, E. Rothhaab (Unter- 

 suchungoi iibcr Tubcrkcl-Bazillcn hcim Rinde. Inaug. Diss., Univ. Bern, J!)08, 

 irp. 25+XLII; rev. in Bui. Inst. Pastcvr, 7 (1909), No. 9, p. 398).— The author 

 confirms the work of Kossel, Weber, and Ileuss (E. .S. R., 15, p. G14) on the 

 characters peculiar to the bovine type of the tubercle bacillus. 



A bibliography of 34 titles is appended. 



The anatamo-patholog'ical forins of bovine tuberculosis, H. Vall^e and 

 P. Chausse (Rci: G^n. Med. Vet., 13 {1909), No. 1-',S, pp. 177-185; abs. in Bui. 

 Inst. Pasteur, 7 (1909), No. 9, p. 396). — During a 2 yeai's' investigation of 

 the forms of bovine tuberculosis, 700 cases were studied. Two forms, the 

 hypei'trophic and the nodular, were distinguished, IG per cent of the cases be- 

 longing to the former and 84 per cent to the latter class. 



Tuberculous lesions of the bovine trachea, A. Chretien (Hyg. Viande ct 

 Lait, 3 (1909), No. 3, pp. 97-102, fig. 1; abs. in Vet. Rec, 21 (1909), No. 1085, 

 pp. 726-728). — The author calls attention to the prevalence of tuberculous 

 lesions of the bovine trachea and describes their nature. 



Tuberculosis of sheep, R. Mayer (Die Schaf Tuberkulose. Inaug. Diss., 

 Univ. Bern, 1908, pp. 77, /^L 1; rev. in Bui. Inst. Pasteur, 7 (190!)), No. 9, p. 

 396). — Tuberculosis is extremely rare in sheep, being found in less than 0.1 of 

 1 per cent. The author here describes very completely 9 cases observed per- 

 sonally. The lesions seem to indicate that the affection originates in the ali- 

 mentary canal, the animals being infected while young through cow's or ewe's 

 milk. The bacilli, which are apparently of the bovine type, are rare and often 

 degenerate. 



A bibliography of 148 titles is appended.
