cut as short as possible. In either case, a complete 

 cure must not be expected, unless the horse remains 

 at fifrass until the disease be removed. 



47. Fistula in the Withers. 



Symptoms. — This troublesome disorder generally 

 commences at the top of the withers. It is small at 

 first, but soon enlarges and spreads on one or both 

 sides. When suppuration takes place, a sanious 

 discharge is conveyed in small channels or pipes 

 through the cellular membrane. 



Causes. — This disorder frequently proceeds from 

 bruises occasioned by the collar or saddle. Injuries 

 of the bone, or whatever produces inflammation, 

 produces the fistula. If it arises from a bad habit of 

 body, the cure is very hopeless. 



Ciwe. — ^As fistulas, if improperly treated, become 

 very obstinate ulcers, it is ahvays best to call in the 

 assistance of a skilful practitioner. His first object 

 will be to ascertain the direction of the fistula or 

 pipes ; and for this purpose, if there be no danger of 

 wounding any of the large blood-vessels, he will lay 

 it thoroughly open. The next object is to restore 

 the surface of the diseased part to a healthy state by 

 caustic applications. The following is recommended : 



Corrosive sublimate,- - 1 drachm. 

 Dissolved in 2 ounces of spirit of wine. 



A pledget of tow dipped in this lotion to be ap- 

 plied to the part, and in three or four days a slough 

 or core will come away. If the surface appears 

 healthy, nothing more is necessary than to keep it 

 clean ; and if the granulations grow^ too luxuriantly, 

 sprinkle over the surface of the woimd a smaU 

 quantity of verdigrease.
