matter to escape thoroughly. In case the swelling is very deep, 

 and causes serious soreness and swelling of the throat, nurse the 

 horse carefully by feeding with warm gruel, give warm drink,

Poll-Evil and Fistula of the Withers. 



The treatment of these difficulties is the same for one as for the 

 other — their characters being the same. 



Poll-Evil is oftentimes caused by the poll striking a beam 

 or against the floor. Sometimes it may be the result of con- 

 stitutional predisposition. 



When the enlargement and inflammation are first noticed, you 

 may may be able to dispose of it by giving a dose of physic and 

 applying cooling applications to the part. 



If the inflammation has not become reduced, clip the hair 

 from the part and rub on some blistering ointment. 



Should the swelling enlarge, open and allow the pus to escape. 



In the treatment of all ulcers keep one point in mind, which 

 is, to make an opening at the bottom if you can, to allow the 

 matter to run out, as matter will always burrow toward the 

 bottom. 



This is done by running a seaton through, bringing it out 

 just below the bottom of the wound. 



Wash out the sore clean. It should be afterwards bathed with 

 any of the healing preparations for ulcers given in another 

 page. 



If pipes are formed requiring caustic medicine, use either chloride 

 of zinc, corrosive sublimate, or any strong escorotic to destroy this 

 growth, after which treat as before.
