 Water, and cover it with an Earthen Cap, or Covering, 

 which they again cover with lighted Coals; which Fire 

 they feed for fome Hours, that the Mafs may grow violent 

 hot, and the Mercury that is in it evaporate in Smoak $ 

 but that Smoak having no Paffage out, it circulates in. the 

 Hollow that is between the Mafs and the Cap, or Cover- 

 ing, till coming down to the Water that is underneath, it 

 condenfes and (inks to the Bottom, again converted into 

 Quickfilver. Tiros little of it is loft, and the fame ferves 

 ieveral Times ; but the Quantity muft be increas'd, be-
