knee on the inside of the foreleg. They usually 

 appear in young horses, seldom cause lameness 

 when the horse is not overworked and are ab- 

 sorbed before the horse reaches maturity. It 

 seldom pays to bother with them, though at 

 times they cause lameness. 



Sweeney is caused by the pressure of the 

 collar in young horses mostly and results in 

 atrophy or wasting away of the muscles of the 

 shoulder. It is a tedious process to restore the 

 muscular tissues to their normal condition, 

 blistering, the insertion of setons and: the injec- 

 tion of turpentine beneath the skin being 

 variously advocated in the treatment of this 

 trouble. Collar galls are caused by the bruising 

 of the tissues by the collar and if net properly 

 attended to result in the formation of fibroid 

 tumors which must be dissected out before the 

 shoulder may be healed over smoothly. Ill- 

 fitting collars frequently cause sitfasts to form 

 on top of the neck. These are pieces of dead 

 skin closely adhering to the tissues beneath and 

 must also be dissected out. It pays to have the 

 collars fit properly. 



Warts are of frequent occurrence about the 

 muzzle of the horse and sometimes they appear 

 on other parts of his body. If the warts are 

 broad and flat saturating them with glacial 

 acetic acid drop by drop daily for a short time 

 will cause them to disappear and the application 

 of castor oil has the same result in many cases.
