the parts it raifeth. And thus, all of them compared together, 

 do roll along till they tumble into fome low place, out ot which 

 they cannot fo cafily get to wander furthcr.When they are thus 

 fettled, they do the more eafily receive into them, and retain 

 fuch heat as is every where to be met withall , becaufe it is dif- 

 fufcd more or lefTe through the earth. This heat if it be fufficient 

 digefteth it into a folide body :the temper of cold likcwife concur- 

 ring in its meafure to this erFe.ft. And according to the variety of 

 thefubftances whereof the firft liquour was made, and which it 

 afterwards drew along with it; the body that refultcth out of 

 them is diversified. In conconfirmation of all which they that 

 deal in mines tell us they ufc to find metalls oftentimes mingled 

 with ftoncs; as alfo coagulated Joyces with both; and earths of 

 divers natures with all three; and they with it,and one with an- 

 other among themfelves. And that fometimes they find the mines 

 not yet confblidated and digefted throughly into mctall ; when 

 by their experience knowing after how many ycares they will 

 be ripe, they (hut them up again till then. 



Now if the hollow place wherein the body flayed (which at 

 the firft was liquid and rolling)be not at once filled by it, but it 

 taketh up onely part ofit;and the fame liquour continueth after- 

 wards to flow thither: then this body is augmented, and grow- 

 eth bigger and bigger. And although the liqueurs fliould come 

 at fcverall times, yet they become not therefore two fcveraJl bo- 

 dies, but both liqueurs do grow into one bodyrfbr the wet parts 

 of the adventitious liquour do mollifie the fides of the body al- 

 ready baked; and both of them being of a like temper and cog- 

 nation, theyeafily ftickand grow together. 



Out of this difcourfe it followeth evidently, that in all forts 

 of compounded bodies whatfoever, there muft of neceflity be a- 

 6tually comprifed fundry parts of divers natures: for othcrwife, 

 they would be but fo many pure degrees of rarity and deniity; 

 that is, they would be but fb many pure elements, and each of 

 them have but enc determinate virtue or operation.
