The best method is to prick the callous part all 

 over as full of holes as possible, with a bodkin, or 

 a sharp instrument about an inch long : to this 

 may be fixed a bit of cork, or elder, in order 

 to prevent the instrument from going deeper than 

 the callous substance, yet it should always be per- 

 mitted to pass through it. This done, bathe the 

 part with vinegar ; and when the blood is stopped, 

 apply the following 



. (RECIPE, No. 135.)
