and popliteal glands. The percentage of infection of these glands is shown in tabular 

 form, from which it appears that in cases of tuberculosis the prescapular glands are 

 affected in 26 per cent of cattle, 40 per cent of cows, and 52 per cent of hogs. Similar 

 variations were observed with regard to the other glands. Observations on the 

 various cases studied indicate that mammary tuberculosis in cows occurs in 1.74 per 

 cent of cases. 



Treatment of bovine tuberculosis by means of the serum of Cuguillere, 

 V. Faure {Prog. Yet., n. ser., 18 (1905), Xo. 1, pp. 7-14)- — According to the author's 

 experience, bovine tuberculosis sufficiently well advanced to be recognized clinically, 

 may be cured by treatment with the serum of Cuguillere. Cures effected by this 

 method were tested by means of tuberculin and by subsequent microscopic exami- 

 nation of the old tuberculous lesions. These tubercles were found to be nonvirulent. 



Protective inoculation of cattle against tuberculosis according- to von 

 Behring, Lorenz (Ztschr. Thiermed., 9 (1905), Xos. 1, pp. 1-22; 2, pp. IS 1-1 44). —In 

 order to obtain as extensive and reliable data as possible concerning results of vac- 

 cination experiments thus far carried out a circular letter of instructions was sent to 

 15 official veterinarians in different parts of Germany. The data thus obtained are 

 presented in a tabular form. Attention is called to the fact that while cattle immu- 

 nized against tuberculosis according to the system of von Behring may subsequently 

 react to tuberculin, this fact was known to von Behring and has been referred to by 

 him in his publications on this subject, 



The resisting power to bovine tuberculosis of two cows previously treated 

 with tubercle bacilli of different origin, A. Eber (Ztschr. Thiermed., 9 (1905), Xo. 

 2, pp. 81-130). — Details connected with the vaccination of cattle against tuberculosis 

 according to the von Behring system are outlined. 



As the result of a thorough study of 2 cows treated in this manner it was found 

 that the subcutaneous injection of 1 gm. of tuberculous material from bovine origin 

 produced a swelling the size of a hen's egg at the point of inoculation in the immu- 

 nized animal. The animal was slaughtered 6| months after inoculation, and at this 

 time merely traces of the infection were discovered. In a nonimmunized animal 

 inoculated at the same time and in the same manner much more extensive swelling 

 took place, followed later by the inflammation of the prescapular lymphatic glands, 

 fever, and other evidence of tuberculosis. 



Similar results were obtained when immunized and nonimmunized cattle were 

 inoculated with 2 gm. of tubercle bacilli of bovine origin. The resisting power of 

 the immunized animal was much greater. 



The reaction curve of tubercle bacilli from different sources in bouillon con- 

 taining different amounts of glycerin, T. Smith (Jour. Med. Research, 13 (1905), Xo. 

 4, pp. 405-408) . — The author had already shown that in glycerin bouillon bovine tuber- 

 cle bacilli change the reaction from acid to alkaline, while similar cultures contain- 

 ing human tubercle bacilli do not become alkaline. In the experiments reported in 

 the present paper it was found that in glycerin-free bouillon growth was quite feeble 

 or absent, while with the addition of glycerin growth became more vigorous, reach- 

 ing a maximum when the bouillon contained 1 per cent glycerin. 



The study of the tolerance of cattle for tuberculin, L. Stubbe and G. Mullie 

 {Ann. Med. Yet., 54 (1905), Xo. 4, pp. 198-205).— Statistical data are given regarding 

 the reaction to tuberculin in 578 cattle. In this number 20 showed a reaction within 

 2 hours, 68 within 4 hours, 135 within 6 hours, while only 23 failed to react after 18 

 hours. The reaction began within 12 hours in 441 out of 578 cases. The author 

 believes as a result of his observations that the reaction to tuberculin ordinarily 

 takes place within a shorter period than has usually been named by investigators 

 of this subject.
