which to referre to Heat , and Cold ; and Mo'tflure , and Drought, 
is a Compendious and Inutile Speculation. Bat of thefe fee

Wee Hi all handle diuers of them now prefently. 
L iquefiable , and Net Liquefiable , proceed from thefe Caufes : Liquefa. 
8 ton is euer caufedby the Detention of the Spirits, which play vvith- 
“ in the body, and Open it. Therefore fuch Bodies as are more Turgtde of 
Spirit-, Or that hauc their Spirits mor cStraitly Imprifoned- Oragaine 
that hold them Better Pleafed, and Content 5 are Liquefiable: For thefe 
three Diffofuions of Bodies, doe arrefl the Emifiion of the Spirits. An Ex¬ 
ample of the fir ft two Properties is in Metals • And of the Laft in Greafe, 
Pitch, Sulphur*,, Butter, wax, &c. The Difpofition not to Liquefie procee¬ 
ded! from the Eafte Emifiion of the Spirits, whereby the GroJJer Ports 
contrad. And therefore. Bodies leiune of Spirits 5 Or which part with 
their Spirits more willingly-, are not Liquefiable • As wood, clay, Free¬ 
stone, &c. But yet, euen many of thofe Bodies, that will not Melt, or will 
hardly Melt, will notwithftanding Soften ; As Iron in the Forge • And a 
Sticke bathed in HorAfhes, which thereby becommeth more Flexible. 
Moreoner, there are fome Bodies, which doe Liquefie, or diflolue by Fire i 
As Metals, wax, &c. And other Audits, which diflblue in watery As Salt, 
Sugar, &c. The Caufi of the Former proceedeth from the Dilatation of 
the Spirits by Meat: The Ca'ufe of the Latter proceedeth from the Ope¬

there are fome Bodies, that diflblue with both • As Gumme, &c. And 
thole be fuch Bodier, as on the One Side baue good ftore of Spirit And 
on the other Side, haliethe Tangible Parts Indigent of Moifiure ; For the 
former helpeth to the Dilating of the Spirits by the Fire -, And the Lat¬

O F Bodies, fome are Fragile • And fome are Tough, and Not Fragile^ 
And in the Breaking, fome Fragile Bodies breake but where the Force 
is, S ome fhatter and fly in many Peeces. Of Fragilty the Caufeis an lm- 
poter.cy to be Extended:. And therefore Stone is more Fragile t han Metall-, 
And fo Fifiile Earth is more Fragile than Crude Earth ; And Dry wood * 
than Greene. And the Caafcof this Vnaptnefjeto Extension, is the Small 
Quantity of Spirits 5 (For it is the Spirit that furfhefeth the Extenfion or 
Dilatation of Bodies *) And it is euer Concomitant with PorO/ity, and 
with DriueJJc in the Tangible Parts: Contras wife , Tough Bodies haue meve 
Spirit, and fewer Pores, and Moifier Tangible Parts: Therefore wee fee
