Chap. IX How the Volatile Stone May Againe Be Fixed
AFter all these things, this stone thus exalted, must be incerated with the Oyle that was extracted from it in the first operation, being called the water of the stone: and so often boyle it by sublimation, till by vertue of the firmentation of the earth exalted with it, the whole stone doo againe descende from heauen into the earth, and remaine fixed and flowing. And this is it which the Philosopher sayth: It descendeth agayne into the earth, and so receyueth the vertue of the superiours by sublimation, and of the inferiours, by descension: that is, that which is corporall, is made spirituall by sublimation, and that which is spirituall, is made corporall by descension.
