 better,,) invite you to obferve with 

 me, that though Gold be the body 

 they affed to be moft converfant 

 with 3 yet it will be very hard to (hew, 

 how the fpecific weight of Gold can 

 be deduced from any or all of the 

 three Principle^ fince Mercury it felf, 

 that is of bodies., known to us, the 

 heavieft next to Gold, is fo much 

 lighter than Gold, that, whereas I 

 have ufualiy found Mercury to be to 

 an equal weight of water, fomewhat, 

 though little, lefs than fourteen to 

 one, I find pure Gold to be about 

 nineteen times as heavy as.fo much 

 water. Which will make it very dif- 

 ficulty not to fay impoffible for them 

 to explain, how Gold ftiould barely 

 by participating of Mercury 5 which is 

 a body much lighter than it (elf, ob- 

 tain that great fpecific gravity we 

 find it to have } for the two other 

 Hypoftatical Principles 5 we know, 

 are far lighter than Mercury. And I
