 latility 5 which Quality depends fo 

 much upon the contexture of the 

 corpufcles that are to be raifed to* 

 gether, that even very ponderous 

 bodies may ferve for volatilizing ad- 

 ditaments, if they be difpofed to fa- 

 llen themfelves Efficiently to the bo- 

 dies they are to carry up along with 

 them. For, though Lead be 5 fave 

 one the heavieft folid we know 

 of, and though Quick-filver be the 

 heavieft body in the world, except 

 Gold 5 yet trialls have affined us, 

 that ghticJ^Jilver it felf being united 

 by Amalgamation with a imall pro- 

 portion of Lead, will by a fire that 

 is none of the violenteft^ and in clofe 

 Veffels^bemade to carry over with it 

 fome of the Lead. As we clearly found 

 by the increafed weight of the Quick- 

 filver that pafled into the Receiver > 

 which., by the way, may make us 

 cautious how we coqciude Quick-
