BOG SPAVIN.-— A round, smooth tumor at the 

 front and on the inside of the hock. It is the result 



of sprains, bruises, or 

 other injuries. When 

 these injuries occur, too 

 much joint oil is 

 secreted, causing a bulg- 

 ing of the ligament. 

 Lameness seldom ac- 

 companies a bog spavin. 

 If lameness be present 

 other structures are cer- 

 tain to be affected, and 

 some pain and heat will 

 be noticed, together 

 with a stiffness of the 

 joint. 



Treatment consists of 

 applications of cold 

 water to the affected 

 parts and a lotion made 

 of 2 tablespoonfuls of 

 acetate of lead in 2 

 quart of water. A blister 

 made of i teaspoonful biniodide of mercury 

 and 4 tablespoonfuls of lard rubbed in a little with 

 the fingers and repeated in ten days or two weeks 

 and continued for some months will correct the 

 trouble. Wash the part having received the blister 

 twenty-four hours after application. It is also ad- 

 visable to tie the horse's head while the blister is 

 on, so that he cannot bite the part.
