242 NASAL GLEET. 



adult or aged horse rather than in the young subject. Some- 

 times the discharge comes from one nostril alone ; more usually 

 from both. Sometimes the submaxillary glands (glands under 

 the jaws), remain tumefied, and sometimes they are not. The 

 Schneiderian membrane (membrane of the nose) discolored by 

 inflammatory action, has become pallid and leaden-hued, but 

 is free from all pustular or ulcerative indications. The dis- 

 charged matter varies in quantity and quality in different in- 

 dividuals, and even in the same horse at different stages of 

 this disease. The ordinary gleet consists of a matter more 

 mucous than purulent, remarkable for its whiteness, about the 

 thickness of cream, and in some cases is smooth and uniform, 

 in others clotty or lumpy ; in other cases it is yellow, and 

 appears to contain in its composition more pus than mucus. 

 At one time it will collect about the nostrils, and become 

 ejected in flakes or masses in pretty regular succession ; at 

 another time there is a good deal of irregularity in this re- 

 spect, the running from the nose ceasing altogether for a 

 while, as though the animal were cured, and then returning 

 with double or treble force. Sometimes fetor is an offensive 

 accompaniment of the discharge ; at other times no fetor is 

 perceptible. The health does not suffer in the least ; on the 

 contrary, it is one of the indications of this disease, that the 

 horse eats and drinks, and has his spirits, as well as though 

 he were quite free from complaint. 



Formerly, these cases were considered to be evidences of 

 glanders, and were called chronic glanders ; many a horse 

 having been destroyed under this mistaken impression. That 

 a case of the kind might not turn to glanders, is, perhaps, 

 more than can be asserted with certainty ; but that, so long as
