WAX BXTBACTING. 179 



methods are employed. Tie the scraps of comb in 

 a piece of muslin or canvas, with a stone, or some- 

 thing weighty, and drop it into a pan of water. The 

 stone is used to keep the bag below the surface of 

 the water. The wax will then melt and rise to the 

 surface of the water. If the bag is occasionally 

 pressed with a stick, lodgings of the wax among the 

 refuse will be prevented. "When it is thought that 

 all the wax has been melted the pan should be re- 

 moved from the fire and placed on one side until the 

 water is cold. The wax will then be found in a cake 

 at the top, and it then can be removed for remelting 

 and refining if necessary.
