218 DISEASES OF HORSES AND CATTLE. 



one drain, lard two ounces. Rub on a third of 

 this with the fingers. It is not necessary to cut 

 off the hair if the blister is well rubbed in. Let it 

 remain on for twenty-four hours, then wash off and 

 rub on a little lard. Repeat every second week 

 until three blisters have been applied. Keep the 

 horse's head tied up while the blister is on. The 

 horse should have a few months' rest after the 

 blisters. If this does not cure it, then fire. This is 

 done by cutting off the hair and using the firing 

 irons made for the purpose. Have them red hot, 

 and burn five or six tracks up and down the en- 

 largement deep enough to almost burn through 

 the skin. The iron should be drawn up and down 

 lightly several times, making all the tracks, then 

 going over them caxefully until you get them to 

 the desired depth, taking care not to burn the 

 coronary band, then rub on a little lard or vase- 

 line. Nothing more is needed for two weeks. At 

 the end of that time if the marks are drying up 

 and there has been no discharge it will be neces- 

 sary to rub on a little ointment made by mixing 

 two drams of cantharides with one and a half 

 ounces of lard and rub on a little of that once a 

 day until there is a discharge from the burned 

 tracks. Keep this up for five or six weeks, then 

 let it heal up, and give the animal several months' 

 rest.

 very rare in the horse, as this joint and the muscles 

 of the hip are not brought into so severe a strain
