Since the aforementioned sulfur causing metals is the element of metals along with Mercury, I now pose the difference in the generation of Mercury and sulfur, although they well cause metal from both sides, namely essential Mercury and sulfur as an accidental part. Yet that sulfur is still twofold, namely living and burning. The living causes metals, although they still differ well from one another according to how much it exists infected by the viscosity of the earth, although simple living sulfur, causing gold and silver, is nothing but a hot and dry vapor, generated from the purest terrestrial dryness, in which fire predominates in all ways, and that is called the element of metals with Mercury. But the generation of common sulfur differs from the generation of Mercury, as was said above, because the wateriness of common sulfur is mixed with most viscous earthiness, with boiling heat, and they have become unctuous. Thus, the generation of Mercury differs in the second part from the generation of this sulfur, since it is generated from most subtle, white, sulfurous earth, with most limpid water, since they are transparent through a very strong mixture, so that one cannot be separated from the other, until it does not rest on a flat surface, nor does it adhere to one touching it because of the dryness of the earth, which altered the wateriness by reason of strong commixture, and therefore it is the element with simple sulfur of all malle-
