leave a permanent mark or blemish. I have 

 therefore omitted it in the above formuliE ; 

 but ill cases of bone spavin, in which severe 

 bhstering is necessary, it may be employed 

 with advantaore. I have for some time em- 

 ployed the following blister for common pm'- 

 poses, and find it more convenient than the 

 others. 



No. 4. 



• Hog's lard, • « ' 6 oz. 



Venice turpentine, : - - 4 oz. 



Bees' wax, - ^ - - 2 oz. 



Yellow resin, -^ - I oz. 



Oil of origanum, .. ^ • i oz. 



Powdered cantharides^ - 3 oz. 



Melt the first four inofreaients; and when 

 removed from the fire, and not too hot, stir 

 in the oil of origanum and cantharides : 

 continue stirring until cold. Should this 

 blister become too hard in winter, it may 

 be softened by rubbing it with a little oil 

 of origanum or turpentine, in a mortar or 

 on a slab.
