No. 4.] CATTLE COMMISSIONERS' EEPORT. 391 



It had never been fed on anything but the milk of a single cow. 

 The cow's milk was microscopically examined, and found to 

 contain the bacillus tuberculosis. Guinea pigs inoculated Avith 

 her milk developed the same disease. A second child fed upon 

 the same milk was developing symptoms similar to those dis- 

 covered in the child that died. Dr. Gage could find no way to 

 prevent the sale of the milk, unless he bought and paid for the 

 cow out of his own pocket. So far as he knew, she was still 

 being used as a milk supply a year later. (Ernst: Hearing 

 before Committee on Public Health, Mass. Leg. of 1891; 

 Publications Massachusetts Society Promotion Agriculture, 

 page 19.) 



May 30, 1879, a cow died of generalized tuberculosis in 

 Providence, R. I., the lungs, most of the abdominal viscera, 

 muscular tissue and udder being tuberculous. The milk had 

 been used in the ftimily. In August the baby was taken sick, 

 and died in seven weeks of tubercular menino-itis. Post mor- 

 tern showed tubercular deposits in the membranes covering 

 the brain and some in the lungs. Two years later a two-year- 

 old child in the same family died of tubercular bronchitis ; and 

 seven years later a nine-year-old boy, "delicate" for years, 

 died of " quick" consumption. So far as known, the family on 

 both sides were rugged and healthy. (Ernst: Report to 

 Massachusetts Society Promotion Agriculture.) 



Olliver, at a meeting of the Academic de Medicine of Paris, 

 stated that a patient of his, a young woman twenty years old, 

 of vicrorous health and without constitutional troul)le, had acute 

 tubercular meningitis (inflammation of the membranes of the 

 brain, of tubercular origin). She had been educated at a 

 boarding-school where thirteen pupils had been ill with, and 

 six had died of, tuberculosis within a few months. The milk 

 supplied to the school was from cows kept on the place. Upon 

 examination, these animals were found to have tubercular ulcers 

 upon their udders, and .after being slaughtered were found to be 

 generally tuberculous. (Bacteriological World, August, 1891, 

 translated from Allgem. Med. Cent. Zeit. ; also La Semaine 

 Medical, Paris, Feb. 25, 1802. 



Tuberculosis localized in the mammary gland is of not un- 

 common occurrence in cattle. Milk from such animals is found 

 to contain the bacilli, and is capable of i:)roducing the disease.
