terize the discharge of glanders from a very early pe- 

 riod. 



It is a singular circumstance, that when one nostril 

 alone is attacked, it is, in a great majority of cases, the left. 



This discharge may continue in so slight a degree as to 

 be scarcely perceptible, for many months, or even two oi 

 three years, unattended by any other disease, even ul- 

 ceration of the nostril, and yet the horse being decided- 

 ly glandered from the beginning, and capable of propa- 

 gating the malady. In process of time, however, it ming- 

 les with the discharge, and then another and a charac- 

 teristic symptom appears. Some of this is absorbed, and 

 the neighboring glands become affected. If there is 

 discharofe from both nostrils, the sriands within the under 

 jaw will be on both sides enlarged. If the discharge is 

 from one nostril only, the swelled gland will be found on 

 that side alone. Glanders, however, will frequently ex- 

 ist at an early stage, without these swelled glands, and 

 some other diseases, as catarrh, will produce them. Then 

 we must look out for some peculiarity about these 

 glands, and we shall readily find it. The swelling may 

 be at first somewhat large and diffused, but the surround- 

 ing enlargement soon goes off, and one or two small, dis- 

 tinct glands remain ; and they are not in the centre of 

 the channel, but adhere closely to the jaw on the affected 

 side. 



The membrane of the nose should now be examined, 

 and will materially guide our opinion. It will either be 

 of a dark purplish hue, or almost of a leaden color, or of 

 any shade between the tvro ; or if there is some redness 

 of inflammation, it will have a purple tinge. Spots of ul- 

 ceration will probably appear on the membrane cover- 

 the cartilage of the nose — small ulcers, usually approach- 

 ing to a circular form, deep, and with the edges abrupt 

 and prominent. When these appearances are observed, 

 there can be no doubt about the matter. 



When ulcers begin to appear on the membrane of the 

 nose, the constitution of the horse is soon evidently af- 

 fected. The patient loses flesh — his belly is tucked up, 

 his coat unthrifty, and readily coming off — the appetite
