ing generally subsides considerably in a short time, and 

 the glands are not in the centre of the channel, but 

 firmly adhere to the jaw. This is a never failing test 

 of the disease, and besides, it is quite certain that if the 

 discharge flows from both nostrils it is not glanders. 

 At this stage of the disease the mucous membrane 

 of the nostril becomes dark purple or of a livid colour, 

 sometimes of a tone intermediate between the two 

 shades. In. some instances there is inflammation of 

 those parts which varies from the common appearance* 

 being of a purple cast instead of the high red which 

 usually accompanies inflammation. This is followed 

 by the formation of small circular tubercles on the 

 lining of the nostrils, and these in a short time ulcerate 

 and discharge puss. When this has taken place, there 

 can no longer be a doubt that the horse is glandered, 

 and care must be taken not to mistake the lacrymal or 

 tear-duct for an ulcer. This duct is a continuation of 

 the skin of the muzzle, which is situated a little way 

 up the nostril, while the ulcerated tubercles are placed 

 upon the mucus membrane above the duct, and well 

 marked by a line of separation. After the formation 

 of tubercles, the animal is sure to have become con- 

 stitutionally affected, its coat will stare and fall off, 

 it will lose flesh, and its belly will be tucked up. 

 Cough will follow, the appetite will be much affected, 

 accompanied by a rapid diminution of strength, the 

 tubercles will multiply, discharge will be more abund- 

 ant, and will assume a purulent and bloody ap- 

 pearance, accompanied by a very foetid smell. The 

 ulceration will extend down to the windpipe, and the
