the Richer Mctall. I remember to haue heard of a Man,skilfull in Metals , 
thata Fifteenth Part of Siluer, incorporate with Gold, willnotbeReco- 
uered by any water oi Separation • Except you put a Greater Quantitie 
of Silutr , to draw to it the LefTe • which (he faid) is the lad Refuge in Se- 
parations. -But that is a tedious way, which no Man (almoft)' will thinke 
on. This would be better enquired* And the Quantitie of the Fifteenth 
turned to a Twentieth * And likewife with fome little Additional!, that 
may further the Intrinjjque incorporation. Note that Siluer in Gold will be 
dete&ed by weight, compared with th eDimenJion- But Lead in Siluer, 
(Lead being the weightier Met all ',) will not bee deteded • If you take 
fo much the more Siluer , as will countcruailc the Oner-weight of the 
Lead . 
G O Id is the only Sulfiance, which hath nothing in it Volatile, and yet 
melteth without much difficulty. The Melting fheweththatit is 
not leiune, or Scarce in Spirit. So that the Fixing of it, is not want of Spi¬ 
rit to fly out, but the Equal! Spreading of the Tangible Parts, and the 
Clofe Coaceruauon of them; Whereby they haue the Idle Appetite, and 
no meanes (at all) to ifllie forth. Jt were good therefore to try, whe¬ 
ther Glajfe Re-Moultcn doe leefe any weight For the Parts in Glajfe ate 
cucnlv Spred • But they arc notfo Clofe as in Gold-, As Wee fee by the 
Eafie Admiflion of Lights Ileat i and Cold • Andby the SmalneJJe of the 
Weight , There bee other Bodies , Fixed , which haue little or no Spi¬ 
rit : So as there is nothing to fly out * As wee fee in the Stujfe , where¬ 
of Copples are made * Which they put into Furnaces • Vpon which Fire 
worketh not: So that there are three Caufes of Fixation * The Euen 
Spreadingbotb. of the Spirits , and Tangible Parts * The clofenejje of the 
Tangible Parts * And the leiuneneffe or Extreme Comminution of Spirits: 
Of which Three,the Two Fird may be ioyned with a Nature Liquefiable-

I T is a Profound Contemplation in Nature, to confider of the Empti- 
neJJ'e (as we may call it) or infatisfa&ion of feuerall Bodies • A nd of their 
Appetite to rake in Others. Aire taketh in Lights, and Sounds, and Smels, 
and Vapours * And it is moft manifeft, that it doth it, with akinde of 
Third, as not fatisfied with his owne former Confidence* For elfe it 
would never receive them in fofuddenly, and eafily. Water and all Li¬ 
quors, doe hadily receive Dry and more Terrcjlriall Bodies, Proportio¬ 
nable : And Dry B0dies, on the othe r fide,drinke in Waters, and Licquors: 
So that, (as it is well faid, by one of tHe Ancients, of Earthly and watry 
Subjlances,) One is a Glue to another. Parchment, Skins, cloth, &c. drinke 
in Liquors, though themfelves be Entire Bodies, and not Comminuted, as 
Sand and Ajhes ■, Not apparently Porous : Metals themfelves doe fe- 
ceiue in readily Strong-Waters * And Strong-Waters likewife doe readily 
pierce into Metals, and Stones : And that strong-water will touch vp¬ 
on Gold , that Will not touch vpon Siluer * And e conuerfo. And Gold,
