82 EXPERIMENT STATION EECOED. 



Contribution to the study of pulmonary tuberculosis induced experi- 

 mentally by inhalation, V. Grysez and D. Petit-Dutaillis {Compt. Read. 

 Soc. Biol. [Paris], 73 {1912), No. 37, pp. 728-730; ahs. in Ztschr. Immunitatsf. 

 u. Expt. Ther., II, Ref., 6 {1912), No. 12, pp. 927, 928).— In the experiments 78 

 guinea pigs were exposed in a si:)ecially constructed lead chamber to a si)ray 

 of an emulsion of bovine tubercle bacilli. Twenty of the animals received one 

 inhalation, and of these 19 died within 17 to 133 days. All showed well- 

 disseminated, cheesy foci, and 3 cavern formations. A second group of animals 

 received 2, 3, 4, 5, 6, 7, and 8 inhalations in from 2 to 36 hours. The guinea 

 pigs which received 4 and 5 inhalations per day showed only slight sclerotic 

 lesions, and almost one-half of the animals were free from tubercular changes. 



In a third group where numerous inhalations were given at intervals of 

 from 8 to 30 days, appreciable evidences of tuberculosis were present in all 

 animals. Some of the animals died, others were killed. 



New researches upon inhalation tuberculosis, P. Chausse {Bui. Soc. Cent. 

 Med. V4t., 89 {1912), No. 16, pp. 361-363) .—This is a summary of a thesis 

 submitted in competition for the Trasbot prize of 1912. See also previous 

 notes (E. S. R., 26, pp. 179, 783). 



Experimental pulmonary tuberculosis in the dog, P. A. Lewis and C. M. 

 Montgomery {Jour. Expt. Med., 17 {1913), No. 5, pp. 527-534, pl- i).— Large 

 quantities of tubercle bacilli of the bovine type introduced directly into the 

 lungs by way of the air passages failed to reproduce a chronic pulmonary 

 tuberculosis in the dog. 



Milk-borne tuberculosis with special reference to impending- preventive 

 legislation, S. Delepine {Jour. State Med., 21 {1913), No. 6, pp. 336-363, figs. 

 2). — This is an extended article dealing with the improvement in the mortality 

 from tuberculosis which has been effected in Manchester, England, by methods 

 of inspection and inoculation. Results obtained in the course of 15 years are 

 summarized as follows: "The proportion of tuberculous milk (as supplied to 

 consumers) has been reduced to nearly one-third of the original amount. The 

 number of farms with cows suffering from tuberculous mastitis has been re- 

 duced to nearly the same extent. The inf activity of the milk which still re- 

 mains tuberculous has been reduced to a much greater extent. The proportion 

 of cases of tuberculosis in children under 5 years of age has been reduced by 

 one-half." 



The author discusses pending legislation looking toward tuberculosis control 

 and eradication. 



Combating bovine tuberculosis with especial reference to the clinical and 

 bacteriological diagnosis of the disease, R. von Ostertag {Die Bekdmpfung 

 der Tuherkulose des Rindes mit besonderer Beriiclcsichtigung der klinischen uiid 

 haktcriologischen Feststellung. Berlin, 1913, pp. XII+591, figs. 88; rev. in 

 Berlin. Tierdrztl. Wchnschr., 29 {1913), No. 17, p. 308). — The successive sections 

 of this work take up the occurrence and distribution of the disease, the signifi- 

 cance which it has from an economic and sanitaiy standpoint, and the necessity 

 for combating the disease in bovines; investigations which have been conducted 

 and the possibility of eradicating the disease: the significance of the various 

 kinds of tuberculosis, i. e., open forms and nonoccult cases, for the distribution 

 of the disease; clinical and bacteriological methods for diagnosing tuberculosis 

 (with 88 illustrations) ; laws in regard to the control and eradication of 

 tuberculosis in bovines; and various kinds of blanks which are used in the 

 control of tuberculosis, official work in regard to tuberculosis, tariffs, etc.
