GLANDERS. 59 



Hence the necessity of attending to the very earliest 

 symptom which possibly may indicate the presence 

 of this complaint; of seriously regarding a slight 

 increased discharge from the nose, or altered colour of 

 its membrane — whether it be accompanied by enlarged 

 submaxillary glands, or even should no tumour be 

 detected. 



The disease may be long stationary. Entire teams 

 of these horses draw waggons, or are employed upon 

 the roads : they outwardly seem to work well for 

 months and years. This should not be permitted, for 

 the contagion of glanders is often widely spread by 

 such means. 



In the next step the discharge is rapidly augmented; 

 from being mucous or glairy, yet transparent, and 

 always, without smell, it becomes purulent, opaque, 

 yellow and foetid. If the nose is then examined, 

 chancres may be seen upon the membrane of the car- 

 tilaginous septum between the nostrils. They are 

 plainly not the excoriations which are sometimes 

 observed in violent catarrh, but they are distinct 

 ulcers, with ragged edges, surrounding surfaces which 

 look sore, but want the red, even, vascular or puru-

 virus empoisons the whole frame. The horse loses 

 flesh, appetite, and spirit ; the coat is pen-feathered ; 

 the skin is harsh, and clings to the bones. The in- 

 flammation extends down the windpipe, and the
