Let thus much suffice as to the generation of Metals; but now by what means they arrive to the utmost end of perfection and Dye, and are hindred in their growth, we will not pass over in silence.
Thus therefore the Case Stands, There is a certain time prefixt to all Creatures, how far they may come or protract their life, which predestinated time if it be cut off, and attaines not unto its scope or end, it comes by accident and may not be imputed unto Nature, and this is done sundry wayes according to the various tempers of such enemies as they meet withal, some are hurt by the cold Air, prohibiting their growth, as is evident in Metals digged from their mines or trunks and exposed to the air, then ceasing to grow, and were they ripe or unripe Metals, so remaining, but if they get a new matrix, then as the seed of a plant on the Earth, they begin again to grow and hasten towards perfection. To some, as to Vegetables and Animals; the aire is the life, of which being robbed, they expire and Dye. The air destroys Fish, the water is their life, but the death and destruction of two-footed and four-footed Animals.
Even as all the elements have their proper ofspring which they cherish, so are they the destroyers of other things, which the rise and death of Metals clearly teacheth.
For as soon as ever (being conceived in the earth) they begin to grow, they become partakers of a certain saltish Nature, as their matrix, in which, and by which, they are afterwards perfected, wherein as long as they remain uninterrupted, they go forward, and are bettered in quality and quantity, but as soon as ever their contrary, as Aire or common Water meets with them, they are stopt from proceeding further in the matrix and Dye.
They being (because of this most subtle salt) while in being, most impatient of both viz. Water and Aire.
Now if the aire invades them, their life, consisting in a Volatile salt, is elevated and drawn back by the Stars: If water breaks in, they dissolve and are washed away, the matrix being destroyed by its contrary Element, whence ’tis that such Metals in their primum Ens, lying Embryon like, and obnoxious even to the smallest corruption, do perish, and never attain to the appointed perfection by reason of such destructive accidents and injuries, whose tender salt is gon into sulphur, and is no more subject to the corruption of either Water or Aire. As for those that are Mature and perfect, if they are not cut off from their stock being extracted out of the Earth, from which they have no more nutriment, their sulphurious covering being laid aside, the defence and safegard of their Nature being banished, they rightly resemble a decrepid Old man, whose Radical moisture is dryed up and are dissolved and eaten up by the same Astral Salt, or Vehement Corruscation, from whence they did spring, and thus are reduced unto Nothing; amongst which, viz. metals, as well as amongst Vegetables and Animals, Nature observes a perpetual Circulation of Life and Death.
It sometimes happens that the diggers finding a metal excavated by the Astral salt, like to the Hony Comb by the Bees, are accustomed to say, that they came thither too late, whence it is concluded that the same corruscation is the begining and end of metals.
Tis of small moment to know who first digged up metals applying them to use; Adam was the first to whom GOD revealed the Art, because he could not want it.
It seemeth certain, that that which was by his successors discovered to Noah, and from him propagated unto us will undoubtedly be conserved unto the Worlds end, because of its great necessity and benefit.
But as this Art is profitable and useful, and noble, so it is chargable, costly, and dangerous, and also uncertain of getting gain, but yet not to be neglected on that account, it being an honest thing, and pleasing to GOD, and managed heretofore by many Prophets and Kings, and now at length, diservedly had in great estimation by us Christians, because of its necessity.
