Inflammation of the Mouth and Tongue {Aphthce^ 



Pustular Stomatitis) . 



The chief forms of mflammation of the mouth and tongue which 

 we usually note in the horse are : 1. A superficial eruption on the 

 mucous membrane, after certain diseases, somewhat similar to that 

 we may see on the lips of a man, at times, during the convalescent 

 stage of intermittent fever. 2. An inflammatory peeling off, in 

 patches, of the mucous membrane of the mouth and tongue ; with, 

 perhaps, the formation of a small amount of matter (pus), at parts 

 where the sores are deep. We may class these two forms under 

 the heading of aphthae. 3. A contagious inflammation (pustular 

 stomatitis) which extends all over the mouth and tongue, and, gene- 

 rally, to the nostrils, as well as to the face, and even to other parts 

 on which the discharge falls. The eruption consists of small 

 nodules, or boils, which ulcerate, and run their course, as a rule, 

 in about a fortnight. A good deal of discharge, and some swelling 

 of the parts, accompany the inflammation. The ulcers lack the 

 chancre-like appearance of those of glanders. The disease may be 

 communicated to cattle and man. In some instances, the horse 

 seems to have received it from cattle, in which case it would appear 

 that contact with the discharge, left, perhaps, on fodder, would be
