852 DISEASES AND THEIE TREATMENT. 



As stated before, chronic catarrli is a dischai'ge from the nose, 

 affecting only the lining membrane of the nose ; and there may 

 be also enlargement of the glands, staring coat, and debility, so 

 that it is sometimes difficult to distinguish one fi'om the other 

 during the early stage of glanders. Then again, ulcerated teeth 

 may produce the same symptoms of discharge from the nose of a 

 very offensive character, which may be taken for glanders. So 

 that, when there are the characteristic symptoms of glanders, it is 

 very important to look closely to the condition of the teeth — is 

 there any enlargement or ulcerous secretions in their neighborhood, 

 which may extend into the nasal cavity ? When the horse is val- 

 uable, and there is any doubt about the case, the best way is to in- 

 oculate some worthless horse with some of the virus ; if glanders, 

 it will show itself very quickly. 



" The usual method of doing this is to first cut off the hair from 

 the side of the neck or other part of the body about the size of a 

 half dollar ; then take a lancet and pass it under the cuticle, or 

 scarf-skin, only deep enough to bring a few drops of blood. The 

 matter is to be introduced into this opening with a thin slip of 

 wood of the form of the lancet. If the matter is glanderous, the 

 part will become sore in two or three days, and a scab will form on 

 it, which, in a fcAV daya will be thrown off, leaving a peculiar kind 

 of ulcer, which will often spread rapidly, causing a painful swelling 

 of the adjacent pai'ts, with corded lymphatics and farcy buds. In 

 about a fortnight the glanders will appear." 



Prof. Robert Jennings, of Detroit, an old veterinarian of much 

 experience, speaks in the Veterinary Journal of Comparative 

 Medicine of a number of cases supposed to be glanders, which 

 proved to be caused by ulceration of the teeth, which he cured 

 without difficulty. Could refer to a number of cases of this char- 

 acter if necessary. The test of inoculation would of course be 

 conclusive. 



Treatment. — The following arc favored prescriptions for 

 farcy : — 



5 grains arsenic.

 For a drench in a pint of water twice a day. — Prof. Williams.
