a tuberculous cow, had a tumid, intractable sore, the tissues of 

 which when excised showed tubercle bacilli. 



A veterinarian, of Chester Co., Pa., in opening a tuberculous 

 cow, cut his knuckle, which healed tardily, remained swollen 

 and when excised, showed typical tubercular lesions including 

 giant cells." 



He quotes from Hartzell the ca.ses of two men wounded in 

 cleaning cattle cars, both of whom had resulting tubercle, arrested 

 in one case by excision, but in the other advanced to generalized 

 tuberculo.sis and death. 



Bang gives the following Danish cases : 



A merchant having two chlorotic daughters secured a fine cow 

 to feed them fresh milk. The cow was killed tuberculous and was 

 replaced by another which also showed tuberculosis, this time 

 affecting the udder. The girls died of tuberculosi.5 at 16 and 18 

 years. Two younger children fed on the milk of sound cows 

 grew up healthy. 



A healthy cow became tubercular, after having been placed in 

 the same stall in which another had died of tuberculosis. A 

 child fed almost exclusively on the milk of these two cows died of 

 tuberculosis. 



A peasant at Silkeborg drank freely of milk freshly drawn. 

 He died of tuberculosis, as did also a cow, and later in the same 

 stable, a pig. 



A peasant had an 1 1 year old cow with generalized tubercu- 

 losis, implicating the udder. The wife of the peasant, formerly 

 healthy, became tuberculous shortly after the udder became af- 

 fected and died at 45. A daughter who, like her mother, used 

 the milk of this cow, died consumptive in the same year. The 

 husband who drank beer, and not milk, remained well. 



A physician fed his two children on the milk of his tubercular 

 cow, and lost both from tuberculosis. Neither parents nor 

 grand-parents were tuberculous. (I/. Pearson in Bull. 75, Tuber- 

 culosis of Cattle). 



Thorne had reports from twenty-two Ohio physicians to the 

 effect that they had traced tuberculosis in their patients to the 

 use of the milk of tuberculous cows, and thirty-three who be- 

 lieved they had reason to suspect the meat and milk supply as the 

 source of cases of consumption. (Ohio Exp. Stat. Bull. 108).
