GHAP. V. 



TH E fourth means of making a 

 body Volatile is, by aflocia- 

 ting the particles to be raifed with 

 fuch as are more Volatile than them- 

 felves,and of a figure fit to be fattened 

 to them., or are at leaft apt, by be- 

 ing added to them, to make up with 

 them corpyfcles more difpofed than 

 they to Volatility. This being the 

 grand Inftrument of Volatilization^ 

 I (hall fpend fomewhat the more time 

 about it : But 1 (hall firft here a little 

 explain the laft claufe, (that I may not 

 be obliged to refume it elfewhere 5 ) by 

 intimating^ that 'tis not impoffible^ 

 that the particles of ari additament s 

 though not more volatile than thofe 

 of the body ? tis mixt with, and per- 

 haps though not volatile at all, will 

 yet conduce to volatilise the body 

 wherewith 'tis mingled. For the par- 

 ticles of the additament may be of 

 fuch figures, and fo aflbciated with 

 thofe of the body to be elevated^
