critical review of the literature of this subjecl is given together with details secured 

 by the examination of •"><> cases in cattle. 



In this study it was found necessary to separate the cases into two classes accord- 

 ing as the uterus or ovary was more extensively affected. Ini'l cases it was found 

 that the ovary was first attacked and that infection spread to the uterus. In 29 

 cases the disease appeared in a more advanced stage in the uterus and the infection 

 was probably primary in this organ. The author believes, however, thai in a 

 majority of cases infection spreads from the oviducl to the uterus. The infection of 

 these organs may take place as a resull of contagion of tuberculosis from the outside. 



Tuberculous nature of diffuse enteritis in cattle, Lienaux and Van Den 

 Eeckhadt {Ann. Mid. VH.,56 | 1906), No. 9, pp. 84 93).- In many cases the authors 

 have observed the coexistence of ordinary tuberculosis and enteritis. A study was 

 made of this matter for the purpose of determining whether the enteritis observed 

 in such cases was of tuberculous origin. In this study small experimental animals 

 were used, as well as cattle, for inoculation purposes. It was found thai the bacteria 



obtained from such cases of enteritis were identical with the tubercle bacillus. 



Three years' experience in protective vaccination of cattle against tuber- 

 culosis by von Behring's method, Strelingeb (Ztschr. Tiermed., 10 1906), No. 

 l-.\ i>\>. 118-182).— Attention is called to the fact that other investigators have fur- 

 nished convincing experimental proof of the importance and effectiveness of von 

 Behring's method of vaccination. The author describes in some detail experiments 

 along this line. 



The method appears to be absolutely harmless to cattle when attention is given to 

 the most obvious requirements of the technique of the operation, [n 62 cases the 

 method was applied to calves which were already tuberculous, and among this num- 

 ber 49 animals appeared to be completely cured by the treatment. The tuberculin 

 test was given to 590 cattle which had been previously vaccinated and kept under 

 observation for a year or more. Of this number only 9 animals or 1.5 percenl reacted 

 to tuberculin. This percentage is quite satisfactory when it is remembered that in 

 similar herds untreated about 50 per cent reacted to tuberculin. 



Vaccination against tuberculosis, Degive kt al. (Ann. Mid. IV/., .',.', (1906), 

 No. .'. j>i>. 70-84). — This v is the report of the commissioner appointed to make a test 

 of the vaccination method proposed by \on Behring for the control of tuberculosis. 

 The animals, after vaccination, were tested by means of subcutaneous and intrave- 

 nous inoculations as well as by feeding virus and exposure by proximity to infected 

 animals. A& a result of this test it is concluded that the vaccination recommended 

 by von Behring does not cause tuberculosis in any case and produces a great natural 

 resisting power toward ordinary contamination. Vaccinated animals can not be 

 infected with tuberculosis even by the use of large doses of virulent material. In 

 carrying out this method of vaccination on a practical scale, it is desirable to keep 

 vaccinated animals from undue exposure to tuberculosis during the t'u-t few mouths 

 after vaccination. It is also recommended that vaccination be not undertaken in 

 stables where broncho-pneumonia prevails at the time. 



The sugar-producing action of the tubercle bacillus, C. Fermi ( Centbl. Bakt. 

 [rtc.]> ; - ^ !,l -> Orig., .}0 [1905), No. ?,pp. 187, 188).— The author tested the reducing 

 power of tubercle bacillus by cultivating it in a potato medium which had previously 

 been shown to contain no reducing reagent. In all cases positive results were 

 obtained or, in other words, the tubercle bacillus was found to possess a reducing 

 power. 



The species of actinomyces, E. H.AAB8 (Centbl. Bakt. [-/'•.],/. AbU, Orig. , 40 (1906) , 

 No. -, />/>■ 180-186). — Specimens of actinomyces from various sources were examined 

 with particular reference to the determination of the relationship between these 

 forms. As a result of the author's investigations it is proposed that the group of
