The second question propounded above is answered in tlie affirmative 

 (although in no instance was the human type of tubercle bacillus isolated from 

 cattle suffering from natural tuberculosis) as follows : " Mammals and man 

 can be reciprocally infected with the disease (tuberculosis)," but whether reci- 

 procity with the fowl and other birds exists must for the present remain 

 unanswered. Mammals generally, with the exception of the rabbit and mouse, 

 were not susceptible to infection with the avian tyiie of bacillus. In addition 

 to this it is pointed out that " bovine animals are not completely immune to the 

 human tubercle bacillus, and adult human beings can be infected with the 

 bovine type, even the pulmonary form of the disease in man being sometimes 

 caused by the bovine tubercle bacillus." 



In regard to question 3, the commission concludes " that the evidence ac- 

 cumulated goes to demonstrate that a considerable amount of the tuberculosis 

 of childhood is to be ascribed to infection with bacilli of the bovine type trans- 

 mitted to children in meals consisting largely of the milk of the cow."

The tuberculo-opsonic index in man and bovine, Steubell and Felbeb 

 (Centbl. Bald, [etc.'], 1. AM., Orig., 54 (1010), No. 1, pp. U-73; abs. in Internat. 

 Centbl. Grsa^n. Tuberknlose Forsrh., // {1910), No. 11, p. 566).— The results of 

 805 determinations with 50 tuberculous subjects show that 38 per cent gave a 

 normal index (between 0.9 and 1.1), 33 per cent were below normal, and the re- 

 mainder above normal. With healthy bovines the values in 98 per cent of the 

 cases were normal with the human tubercle bacillus, and in 71 per cent of the 

 cases with the bovine tyi)e, with 21 per cent of the bovine type above normal. 

 With tuberculous bovines the values with the human type were normal for 83 

 per cent, and with the bovine tyi^e for 58 per cent, with 34 per cent of the bovine 

 type above normal. The active sera of bovines artificially infected with the 

 human tubercle bacillus had normal values in 51 per cent of the cases for th« 

 human type bacillus, and in 45 per cent for the liovine type bacillus. With the 

 human type 4G per cent of the values were below normal, and for the bovine 

 type 52 per cent. 



In regard to renal tuberculosis in the bovine as an open condition, Kal- 

 LiNA {1st die Nicrcntuhcrkulosc des Rindcs znr ''offcnen tuberkulose" zu 

 rechnen? Inaug. Diss., Univ. Giessen, 1910, pp. 40, pi. 1; Arch. Wiss. u. Prakt. 

 Tierheilk., 36 {1910), No. 2, pp. 131-116, pi. 1; abs. in Internat. Centbl. Gesam. 

 Tuberkulose Forscli., 4 {1910). No. 8, pp. 406, 4G7).—On the basis of his work 

 the author puts renal tuberculosis of bovines in the category of open tubercular 

 processes. 



About anaphylaxis in tuberculosis, C. Vallardi {Ztschr. Immunitdtsf. u. 

 Expt. Thcr., I. Orig., 7 {1910), No. 3, pp. 58i-3S8 ) .—Proceeding according to the 

 methods utilized by other workers, typical anaphylactic symptoms could not be 

 noted. Objective symptoms such as a fall in temperature and the lowering of 

 complement were also absent. 



Action of ovarian substance upon tubercle bacilli, H. Wittgenstein 

 {Wiener Klin. Wehnschr., 22 {1909), No. 51, pp. 17S5-178S, figs. 2; abs. in 

 Centbl. Bakt. [etc.], 1. Abt., Ref., 46 {1910), No. 13-14, pp. 398, 3PP).— Tubercle 

 bacilli which were kept in ovarian extracts for from 15 to 20 days lost much of 

 their virulence. 



About tuberculosis immunity — Immunity in active tuberculosis, R. Kbaus 

 and R. A'olk {Wiener Klin. Wehnschr., 23 {1910), No. 19, pp. 699-701; abs. in 

 Internat. Centbl. Gesam. Tuberkulose Forsch., 4 {1910), No. 11, p. 563). — The 

 results show that resolved or healed tuberculosis leaves no immunity behind, 

 and therefore indicate that no immunity can be expected by vaccinating with 

 virulent bacilli. Furthermore, it is apparent that it is not possible to immunize
