of the disease, and, for many months before this, glanders 

 may have existed in an insidious and highly-contagious form. 

 It must be acknowledged, however, that, in the majority of 

 cases, some degree of stickiness does characterize the dis- 

 charge of glanders from a very early period. 



" It is a singular circumstance, for which no satisfactory 

 account has yet been given, that when one nostril alone is 

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

 M. Dupuy, the director of the veterinary school at Toulouse, 

 gives a very singular account of this. He says that out of 

 eighty cases of glanders, that came under his notice, only one 

 was affected in the right nostril. The difference in the af- 

 fected nostril does not exist to so great an extent in Great 

 Britain ; but, in two horses out of three, or three out of four, 

 the discharge is from the left nostril. 



"This discharge, in cases of infection, may continue, and 

 in so slight a degree as to be scarcely perceptible for many 

 months, or even two or three years, unattended by any other 

 disease, even ulceration of the nostril, and yet the horse be- 

 ing decidedly glandered from the beginning, and capable of 

 propagating the malady. In process of time, however, pus 

 mingles 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 discharge 

 from both nostrils, the glands 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 exist 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 dif- 

 fused, but the surrounding enlargement soon goes off, and 

 one or two small distinct glands remain ; and they are not 

 in the center of the channel, but adhere closely to the jaw 

 on the affected side.
