The converse is equally possible, at least theoretically. If it is 

 not thought possible to jirohibit cattle-men from sleepinjr in cattle- 

 houses conlaiiiin*; tuberculous cows, the least can be done is to warn 

 the proprietors of the risks of this practice, and of the responsibility 

 they may eventually incur. The nightly supervision of the suspected 

 cow-shed can be etTected by means of a glass building looking on the 

 cattle-sheds, but having no direct communication with them. 



B. — Meat obtained from tuberculous animals is rarely dangerous, 

 and when it is da^igerous it is only slightly so. The established regu- 

 lations for the inspection of tuberculous meat would be suflficient to 

 prevent even the shadow of danger, if such regulations were ap- 

 plied always and everywhere. 



Unfortunately this is not the case. 



The inspection of meat is oi'ganized only in a small number of large 

 towns; it ought to be done everywhere, in villages as well as in 

 towns, and it should be everywhere forbidden to sell meat not bear- 

 ing the stamp showing that it has been declared to be wholesome 

 hy a competent iwspector. This inspection could be easily carried 

 out, and at little cost, on a similar plan to that adopted in Belgium 

 for many years. 



C. — The milk given by tuberculous cows is rarely dangerous, but 

 when it is dangerous it is most often so in a very high degree; hence 

 the necessity of submitting cow^-houses to a periodical inspection 

 when the milk yielded is destined for public consumption. Cows 

 being really only dangerous when they ha^e a tuberculous udder, the 

 inspector's attention should be drawn to the state of the udder. 

 Any cow showing clinical signs causing suspicion of the existence 

 of a tuberculous mastitis, or of serious visceral tuberculosis ought 

 to be isolated at once, pending the making of a diagnosis, this being 

 easily and rapidly done by the present process; the milk should be 

 boiled before being sold and consumed, even by the animals on the 

 farm. The dairyman should be obliged to give information to the 

 inspector as soon as he has ascertained the appearance of a mastitis 

 of any sort. When the diagnosis is confirmed, the diseased cow 

 should be rigorously excluded from giving milk, and should be 

 slaughtered without the least delay. Lastly, the sub-products of 

 butter or cheese manufactories (skimmed milk, butter-milk whey, 

 etc.,) should not be delivered for the consumption of persons or ani- 

 mal until they have been pasteurized at the minimum temperature 

 of 85 centigrade."
