Inflammation of the Mouth and Tongue {Aphthm, 

 Pustular Stomatitis). 



The chief forms of inflammation of the mouth and tongue usually 

 noted in the horse are : 1. A superficial eruption on the mucous 

 membrane, after certain diseases, somewhat similar to that seen 

 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. These two forms may be classed under the 

 heading of aphthae. 3. A contagious inflammation (pustular 

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

 generally 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 appea,rance 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,
