were tuberculous. Congenital tuberculosis was found in 0.42 per cent, and 

 from this tbe author concludes that congenital tuberculosis is relatively rare 

 among bovines but occurs frequently enough to be given consideration in com- 

 bating bovine tuberculosis. 



The tonsils of the bovine and their relation to the production of tubercu- 

 losis, M. Devbient (Die TonsiUen dcs Rindes und Hire Bezichung zur Entstc- 

 hiing der Tuherkulosc. Inaiig. Diss., Univ. Bern, 1908, pp. 36, pis. 7). — The 

 work deals chiefly with the part played by the tonsils as avenues for infection, 

 particularly for tuberculosis. The results of anatomical, histopathological, and 

 bacteriological studies show that primary tuberculosis from tonsillar infection 

 is a rare occurrence, the tonsils being as a rule infected secondarily and from 

 the bronchial secretions. 



A case of tuberculosis in the ass, E. Cesari (Hijg. Viande et Lait, Jf (1910), 

 No. 6', pp. 33J-338, figs. 2). — A complete statement of the pathological findings 

 on autopsy in the case of tuberculosis in the ass. Tuberculosis in the ass is of 

 rare occurrence. 



The granular form of tubercle bacilli taking Much's stain, Wehri.i and 

 Knoll [Bcitr. Klinik Tubcrkulosc, t.'i {1909). No. 2; abs. in VentbJ. Bakt. [etc.], 

 1. AM., Rcf., 1,6 (1910), No. 13-1. i. p. 3.97).— The authors were able to obtain 

 material which took both the Much and Ziehl stain, but there were a few bac- 

 teria which could only be identified with Ziehl's stain. In 50 per cent of the 

 cases the bacilli only took Gram-Much's, and from this finding the authors con- 

 clude that the older methods alone will not suffice for the detection of tubercle 

 bacilli. 



The diagnosis of tuberculosis in animals by the conjunctival and cuta- 

 neous reaction, F. Haag (Untersuehungcn iibcr die Feststellnng der Tubcrku- 

 losc nach conjunctivuler und ciitancr Einvcrleibung von Tiibcrkulin^ Inaug. 

 Diss., Univ. Bern. 1908, pp. -'/7). — As a result of testing numerous sheep and 

 bovines with the cutaneous test and utilizing various strengths of old tuber- 

 culin, the author concludes that the test, owing to its unreliability, is of no 

 practical value for animals. The ophthalmic test in a number of instances gave 

 positive results in sound animals. Precautions must therefore be taken in pro- 

 nouncing an animal tubercular on the basis of this test. Neither the cutaneous 

 nor cun.iunctival test gave a rise in body temperature. 



The diagnostic and prognostic value of opsonic investigations with tuber- 

 culosis, FoRNET and Krencker (Arch. Klin. Med., 91 (1909), No. 3-4; obs. in 

 Ccntbl. Bakt. [etc.], Abt., Ref.. .',6 (1910), No. 13-1.',, pp. },15, //i6).— The au- 

 thors investigated 35 definite clinical cases of tuberculosis, 17 of which were 

 suspected of being tubercular and 48 of which exhibited no evidence of tubercu- 

 losis. From the findings it is concluded that the opsonic index estimation is of 

 great A'alue in diagnosis but of no value in regard to prognosis. 



Ophthalmo reaction with bovotuberkulol and tuberculin brut, L. Opalka 

 and A. During (Ztschr. Infcktionskrank. u. Hyg. Haustiere, 6 (1909), No. 3-J,, 

 pp. 270-281). — A description of the new method of utilizing tuberculin (bovo- 

 tuberkulol D. I. 50 per cent solution and tuberculin brut) for the diagnosis of 

 tuberculosis, the results therefrom seeming to furnish concordant results. Each 

 reaction having a purulent secretion after a period of from 10 to IS hours after 

 the injection is considered positive. The intensity of the reaction stands in no 

 relation to the age or degree of the diseased condition. The reaction is purely 

 a local one. 



Tuberculin diagnosis with simultaneous metabolism experiments, Saat- 

 HOFF (Miinchcn. Med. Wchnsehr., r)6 (1909),, No. J,0, pp. 20.',l-20Ji7; abs. in 

 Ccntbl. Bakt. [etc.], 1. Abt., Ref., .',6 (1910). No. 13-1},, pp. J,ll-J,]3).—T\ie au-
