Duntjrr in Meat. The flesh is not so dangerous as the milk > 

 tuberculous cows. It is quite rare to find tubercle in the sub- 

 stance of the muscle of cattle. They are common, however, in 

 the lymphatic glands lying between the muscles: but in s\vin' 

 they are common, even in the red flesh. The flesh of tuberculin ^ 

 pigs is therefore far more dangerous than that of consumptive 

 cattle. 



A further safeguard against the eating of the flesh of animals 

 is that it is cooked before it is eaten, while milk as a general 

 thing is not. In meat that is thoroughly cooked, all the germs 

 of the disease are destroyed. Thoroughly cooking or boiling the 

 milk renders it entirely safe to be used as an article of food. 



BLACKLEG BLACK QUARTER. 



Blackleg is a very fatal and infectious disease of young cattle, 

 which is at the present time causing considerable mortality among 

 calves and young cattle in various portions of Texas, as well as 

 in other States of the Union. It is a world-wide disease, causing 

 large losses among young cattle in Germany, France, Italy, Bel- 

 gium, Australia, England, etc. In this country it is known by 

 various names, such as blackleg, black quarter, quarter evil, quar- 

 ter ill, symptomatic anthrax, etc. Until within the last few years 

 it was considered identical to anthrax, but it is now proven to be 

 a specific disease produced by bacilli (germs), which are easily 

 distinguished from anthrax bacilli. Cattle between six months 

 and four years of age are most susceptible to the disease. Certain 

 pastures and. districts are more favorable to the growth of the 

 bacillus, therefore the disease is more common there. Swamps, 

 bottom lands, or any low lands along streams that are subject to 

 inundations and floods are the most frequent places for outbreaks 

 of the disease, although it will occur in any locality 

 of soil, location, altitude, etc.
