Vaseline, or lard 1 ounce. 



Pulverized Catharides, or Spanish Fly H drams. 



Mix well tog^ether and rub the blister along the swollen part 

 of the neck. Tie the horse's head short so he can not rub it. 

 Rub the blister in well and grease the place where you blistered 

 in three days after ; allow it to remain two or three weeks, 

 or until it heals up, and if the swelling" is not down, blister ag'ain 

 and follow out the same directions in this as in the first blister. 

 In after treatment do not turn the animal out to pasture for a 

 year or so, for his head will swell up on account of his not having- 

 the use of this vein ; keep him in the stable and feed him out of a 

 high manger, and by doing' this he will be just as useful as ever, 

 for after a while the other jugular vein will enlarge so it will do 

 the work of both the veins. In buying a horse look at both sides 

 of his neck to see that the veins are all right.
