82 THE MULE. 



very diiScult to heal. If there is any such thing a9 

 checking the disease in its progress, it is in these three 

 cases. 



I have observed that when it has been taken in a 

 sore mouth .it has followed down the cheek to the sub- 

 maxillary gland, and ended in a clear case of glanders 

 or farcy. There is another form in which this disease 

 can be taken, and which is, of all others, the most 

 treacherous and dangerous, yet never producing death 

 without the agency of otKer diseases — always carrying 

 with it the germs of infection, and ready to convey it to 

 debilitated subjects and cause their death. The animal 

 will still live himself, and show no sign of disease further 

 than I am about to describe in the position. It is that 

 which is taken in at the nostrils and attacks the sub- 

 maxillary glands, which become enlarged and will 

 remain so. When these become overloaded there will 

 be a discharge at the nose. That being thrown off, it 

 may be some time before any further discharge will be 

 seen from the same source. In some cases, when the 

 discharge is constant, this can be easily distinguished 

 from gleet or ozena, from the healthy and natural appear- 

 ance of the membranes of the nose, which at first are 

 pale, then become fiery red or purple. In gleet the 

 discharges from the nostrils, as in ozena, are of a very light 

 color. In glanders they are first of a deep yellow, then 

 of a dirty gray — almost slate color. 



Mules affected with glanders of this kind, although it 

 may seem hard from their otherwise healthy appear- 

 ance, should be destroyed. They indeed carry with 

 them the germs of infection and death, without any
