NASAL GLEET. 543 



NASAL GLEET OZCENA. 



This consists in a chronic discharge from one or both 

 nostrils derived from the nasal chambers, the nasal sinuses, 

 or the guttural pouches. I include the cases of suppuration 

 in the guttural pouches under this head, because, in practice, 

 such a condition is usually brought under our notice as an 

 ordinary nasal gleet. 



I have carefully studied the different forms of nasal 

 catarrh, which are apt to persist for months unless properly 

 treated, and there is no doubt that a large number of horses 

 have been injudiciously destroyed for glanders, when suffer-

 without intermission. The submaxillary glands are very 

 slightly, if at all, enlarged, loose, and have no tendency to 

 adhere to the jaw. If the animal's constitutional state is 

 bad, there may be slight ulcers on the nose, close to the 

 exterior nares, but such a symptom is usually indicative of 

 a transition from the chronic nasal gleet to true glanders. 



A diagnosis is much facilitated by treating the case. I

 with Key's tube. 



INJECTION OF FLUIDS INTO THE NOSE. 



Fluids are sometimes poured into the nose that they may 

 be swallowed ; but, usually, the internal exhibition of reme-
