_Of the naturall principles, and procreation of Minerals._
Secondly, I will perfectly declare the naturall principles & procreations of Minerals: where first it is to be noted, that the naturall principles in the mynes, are _Argent-uiue_, and _Sulphur_. All mettals and minerals, whereof there be sundrie and diuers kinds, are begotten of these two: but I must tel you, that nature alwaies intendeth and striueth to the perfection of Gold: but many accidents comming between, change the mettalls, as it is euidently to be seene in diuers of the Philosophers bookes. For according to the puritie and impuritie of the two aforesaide principles, _Argent-uiue_, and _Sulphur_, pure, and impure mettals are ingẽdred: to wit, Gold, Siluer, Steele, Leade, Copper, and Iron: of whose nature, that is to say, puritie, and impuritie, or vncleane superfluitie and defect, giue eare to that which followeth.
Gold is a perfect body, engendred of _Argent-uiue_ pure, fixed, cleare, red, and of _Sulphur_ cleane, fixed, red, not burning, and it wanteth nothing.
Siluer is a body, cleane, pure, and almost perfect, begotten of _Argent-uiue_, pure, almost fixed, cleare, and white, & of such a like _Sulphur_: It wanteth nothing, saue a little fixation, colour, and weight.
Steele is a body cleane, imperfect, engendred of Argent-uine pure, fixed & not fixed cleare, white outwardly, but red inwardly, and of the like Sulphur. It wanteth onely decoction or digestion.
Leade is an vncleane and imperfect bodie, engendred of Argent-uiue impure, not fixed, earthy, drossie, somewhat white outwardly, and red inwardly, and of such a Sulphur in part burning. It wanteth puritie, fixation, colour, and fiering.
Copper is an vncleane and imperfect bodie, engendred of Argent-uiue, impure, not fixed, earthy, burning, red not cleare, and of the like Sulphur. It wanteth purity, fixation, and weight: and hath too much of an impure colour, and earthinesse not burning.
Iron is an vnclean and imperfect body, engendred of Argent-uiue impure, too much fixed, earthy, burning, white and red not cleare, and of the like Sulphur: It wanteth fusion, puritie, and weight: It hath too much fixed vncleane Sulphur, and burning earthinesse. That which hath bene spoken, euerie Alchimist must diligently obserue.
