 copy, but with some alterations and many additions, which 

 I trust will be found calculated to facilitate and improve

 boiling, witho\it taking them off the fire, add five ounces 

 of white wax, broken into small pieces, stirring and beat- 

 ing the different ingredients together, till the wax is per- 

 fectly melted and has boiled. Then take the composition 

 off the fire, as boiling it longer than necessary would only 

 harden the wax, and prevent its mixing so well afterwards 

 with water. "When the composition is taken off the fire,
