scientific observers, proving that the milk is often afiected, 

 even thouali the disease has shown no localization in the milk 

 glands. 



Hirschberger experimented with the milk from twenty tuber- 

 culous cows, and in fifty-five per cent, of all the samples exper- 

 imented with he found the bacillus of tuberculosis. 



Dr. Demme records the case of four infants in the Child's 

 Hospital at Berne, the issue of sound parents, without any 

 tuberculous ancestry, that died of intestinal and mesenteric 

 tuberculosis, as the result of feeding on the unsterilized milk 

 of tuberculous cows. They were the only cases in which he 

 was able to exclude the possibility of other causes of the dis- 

 ease, but in these he was satisfied that the milk was alone to 

 blame. (Law : Cornell University, Experiment Station, Bulle- 

 tin 65, page 137.) 



The infant son of a college mate of one of us, a comparatively 

 strong and healthy child of twenty-one months, visited his uncle 

 for a week. While there he drank the unsterilized milk of a 

 cow which was soon after condemned and killed in a state of 

 generalized tuberculosis. A few weeks after his return, the 

 child began to fail, and died three months after the fatal visit, 

 a mere skeleton, with tabes mesenterica, or consumption of the 

 bowels. Both of the child's grandfathers had died of tubercu- 

 losis wdien over sixty years of age, as well as two grand-aunts 

 and one grand-uncle. The child never saw but one of these, 

 and him but two or three times, and for short intervals only. 

 A second child brought up on sterilized milk is in robust health. 

 Both parents are in excellent health. (Private letter to J. L. H. ; 

 also reported by Law, ibid., page 137.) 



In the practice of Dr. Stang of Amorback, a well-developed 

 five-year-old boy, from sound parents, whose ancestors on both 

 sides were free from hereditary taint, succumbed after a few 

 weeks' illness, with acute miliary tuberculosis of the lungs and 

 enlarged mesenteric glands. A short time before, the parents 

 had their family cow killed, and found her the victim of ad- 

 vanced pulmonary tuberculosis. (Law : Cornell University, 

 Experiment Station, Bulletin 65, page 137.) 



In the spring of 1890, Dr. Gage, city physician of Lowell, 

 Mass., had as a patient an infant which died of tubercular 

 meningitis. Its parents were healthy and surroundings good.
