sanitarium is and should be a safer place than the average com- 

 munity, in which 15 per cent, and upward are tuberculous. The 

 educational influence of such an institution should decrease tuber- 

 culosis in the surrounding districts. 



Cases of Direct Infection from Man to Ox. Chauveau induced 

 tuberculosis in cattle by feeding the tubercle from" the lungs of 

 man. ^ 



Nocard relates that a Beauce farmer, with a finely appointed 

 stable 'and healthy herd, in 1883 employed a dairyman who had 

 cough, profuse expectoration, and occasional haemoptysis, and wha 

 had been several times in the hospital in consequence. He slept 

 in the cow stable directly over the cows. In 1886 two cows, 

 stalled immediately beneath him, showed ill health and were put - 

 up to fatten, but did badly and showed extensive tuberculosis when 

 butchered. The dairyman stayed until 1891, 'having to go to the 

 hospital several times in the interval. In 1892 the tuberculin test 

 was applied and seven more cows were found to be tuberculous. 



Huon tells of a cow bought to furnish milk for calves used to- 

 raise vaccine. She stood the tuberculin test, and was carefully 

 secluded from all other cattle, but soon began to fall off, and in 

 six months was very much emaciated, responded to the tuberculin 

 test, aad when killed showed extensive tuberculosis. Her care- 

 taker at the vaccine establishment had what was believed to be 

 chronic bronchitis, but when he died, soon after, this was found 

 to be extensive pulmonary tuberculosis. 



Bollinger inoculated a three-months' calf with liquid from 

 human tubercle and killed it seven months later. Fibroid 

 pedunculated tumors, from a pea to a walnut in size, hung from 

 the mesentery and spleen, and the mesenteric and retroperitoneal 

 glands were tubercular. ^ 



Sidney Martin furnishes the following : Four calves were fed 

 70 c.c. of sputum containing a large number of bacilli. Three 

 were killed after four, eight, and twelve months respectively,, 

 and had severally 53, 63 and 13 nodules on the small intestine, 

 mostly on Peyer's patches. Two calves received at one dose 440- 

 c.c. of tuberculous sputum, and were severally killed after eight
