intervals. The matter discharged in this disease 

 differs from a common catarrh in its specific 

 gravity. If a small quantity is dropped into 

 water it sinks, and it will not mix with water if 

 stirred with it ; whereas the mucous discharge of 

 a common cold swims near the surface, and pre- 

 serves its slimy consistence although stirred, and 

 will not commingle with it. 



A singular character of the glanders is that it 

 always attacks the left nostril, very few cases 

 having ever been seen in which the horse was 

 glandered in the right nostril. Mr. Dupay, a 

 celebrated veterinary surgeon and director of the 

 School of Surgery at Toulouse, mentions that out 

 of eight hundred cases of glanders which came 

 under his care during his practice, only one was 

 affected in the right nostril. Shortly after the 

 discharge from the nostril takes place, the horse 

 becomes affected in the glands of the lower jaw, 

 which swell to a considerable extent, and ulti- 

 mately become attached to the bone. Another 

 character by which this disease is well known is, 

 that at no time is the discharge from the nostrils 

 accompanied by a cough. Some considerable 

 time after the discharge has made its appearance, 

 the gluey substances will be seen accompanying 

 the mucous discharge. It is this pus, mingling 

 with the other gluey matter, which, absorbed by 

 the circulating vessels and carried to the gland, 

 affects it. However, in common cold the gland 

 is sometimes swollen, but in the real glanders 

 the swelling generally subsides considerably in 

 a short time, and the glands are not in the centre
