(7) Now to speak in a creaturely way, Sulphur, Mercurius, and Sal, are understood to be thus. S U L is the Soul or the Spirit that is risen up, or in a Similitude [it is] God: P H U R is the Prima Materia, or first Matter out of which the Spirit is generated, but especially the i Harshness: Mercurius has a fourfold Form in it, viz.

Then it is prepared and becomes a Salt fixed which will melt on hot Silver plate like wax; but before you set this your Salt out, set it again [in] the furnace of putrefaction that it may dissolve of itself, then let it cool, open your Glass and you will find your Matter lessened a third part. But instead of your former Salt Water you will have a fine Sweet and very penetrating Water which the Philosophers have hid under very wonderful Names--It is the Mercury of all true Philosophers, the Water out of which comes Gold and Silver, for they say its Father is Gold and its Mother is Silver. Thus hast thou the strength of both these Luminaries conjoined in this Water, most true, in its right Pondus.
