take any further pains to trace out their origine: and the likeig 

 of their contraries from the contrary cau!e; to wit, of thofe bo- 

 dies that arc confident, hard, lean, an'" 1 gritty, all which do evi- 

 dently fpringfrosn dcnfuy. As for fmoothncire, we have alrea- 

 dy fhcvved how that proceeded! from an aiery or oily nature} 

 and byconleqiience, from a certain degree ofr?rity. And there- 

 fore roughneflc (the contrary of it) mufi proceed from a pro- 

 portionable degree of denfity. Tough nefle is allb a kind of du- 

 ctiluy, \vhich we have reduced to watrineife, that is, to another 

 degree of rarity; and consequently brittlenefle mud arifc from 

 the contrary degree of denfuy. Laftly, groffeneiTe and fubtil- 

 nefle do confift in a difficulty or facility to be divided into fmali 

 parts, which appearech to be nothing elfe but a certain deter mi- 

 nation of rarity and denfity. And thus we fee how the fevcrall 

 coiyjflexions of bodies arc reduced to the foure elements that 

 compound them : and the qualities of thofe bodies, to the two 

 primary differences of qualitative things by which the elements 

 ate diversified. 



21. And out of this difcourfe it will be evident, that thcfe com- 



and qualities, though in diverfe degree?, muft ofnecef- 

 i ,ke^ fuy be found vvherefocvcr there is any variation in bodies : rbr 

 ^ccing there can be no variation in bodies,but by rarity and den- 

 Hey; aitd that the pure degrees of rarity and denfity do make 

 uponcaith. ^^ ^^ moifture, and drincffe, and(in a vvordjche fonre ele- 

 ments; it is evident, that vvhcrefoever there is varie-.y of bodies, 

 there mitft be the foure Elements; though peradventure far un- 

 like thefe mixed bodies which we call elements. And again, be- 

 caufe tkefc elements cannot confift without motion; and becaufc 

 by motion they do ofneceflity produce mixed bodies, and forge 

 outthofe qualities which we come from explicating; it rnuftby 

 like neceffity follow, that wherefoever there is any variety of 

 active and paflive bodies; there mixed bodies likcwife muft re- 

 fide of the fame kinds, and be indued with qualities of the like 

 natures, as thofe we have treated of;though peradvemure fijch as 

 are in other places of the world remote from us, may be in a de- 

 gree far different from ours. 



Since then it cannot be denied, but that there muft be notable 

 variety of active and pafliye bodies wherefoever there it light: 

 neither can it be denied but that in all thofe great bodies from
