212 BOARD OF AGRICULTURE. 



post-mortem examinations revealed a perfect generalized form of 

 tul)ereulosis, with the local lesion of the bowels, tahes viesenterica^ 

 shown in a marked degree, some of the glands being as large as a 

 man's fist. The morbid deposits in the chest cavity, also, were 

 none the less remarkable. The Inngs were studded with crude 

 tubercles, some forty in number, varying in size from a pea to a fil- 

 bert. The bronchial glands were also involved, but the liver, 

 spleen and kidneys were not affected. 



Thus, in the space of fifty-two days, we have three typical ex- 

 amples, nearly uniform in appearance, of the artificial production of 

 this malignant malady- through the digestive organs. In presence of 

 these facts, therefore, I trust that all inquirers after the truth of this 

 matter will be forced to conclude with our illustrious pathologist 

 that the virulence and contagious properties of tuberculosis are now 

 demonstrated beyond a doubt. And the fact that bovine animals 

 have contracted this disease through the agency of the feed gives 

 us an additional source of danger, for creatures confined in the 

 same stable or pasture, and drinking from the same ponds or 

 trouglis, are constant!}' liable to swallow some of these germs in the 

 mucous discharges from the nostrils of their affected comrades. In 

 fact, it is never safe to put another animal in the same stall where 

 one has sickened and died of this complaint without thoroughly 

 renovating the apartment. Nor would I allow an affected creature 

 to mingle with the healthy stock about the yard. 



DANGERS OF DISEASED MEAT. 



The meat from cattle affected with tuberculosis is not unfre- 

 quently seen in American markets, especiallv in our larger cities, 

 and even in country towns. Yet, owing to the lack of public 

 appreciation of any sanitar)' police measures to control such traffic, 

 little or no complaint is made when we are served with consump- 

 tive beef. Thirteen years ago, after many opportunities for obser- 

 vation on this subject, I called public attention to the prevalence 

 of this malignant malady among our dairy stock, that I believed 

 was not generally recognized ; and I now aflEirm with renewed 

 assurance, in a pathological point of view, that the baneful con- 

 sequences to our health from the use of infected meat and milk are 

 not surpassed in the whole catalogue of contagious affections. 



Such infected meat, therefore, should not be used ; for an}' 

 organ or texture in which tubercle has been deposited is surely a
