In like manner understand, that the first Matter of Metals must be observed, known, and found out by the revelation of their last Matter, which last Matter, as there are the perfect Metals, must be separated and divided asunder, that it may plainly appear singly before the Eyes of men. Out of which separation may be judged and learnt what the first Matter was at the beginning, out of which the last was made. Accept of this Advice concerning _Luna_ at present. I could have said more, but I must desist at this time until another opportunity; and intreat you heartily, admonishing you by your Conscience, that you observe all that which I have revealed unto you, of all those Letters which are contained in the middle between _Alpha_ & _Omega_, & that you keep all the Speeches & Writings, that you may not undergo a denial of pardon for your Sins, & a continued perpetual Vengeance for Eternity; which I at last reveal unto you thus: Take the Sky-coloured Sulphur extracted out of _Silver_, rectified with Spirit of Wine, dissolve it according to its Quantity in the White Spirit of _Vitriol_, and in the sweet-sented Spirit of _Mercury_, coagulate them together by the fixation of the Fire, you have the White Tincture in your Hands with all its Medicines; but if you can get all their _primum Mobile's_, it is then needless, because you can perfect the Work at once. CHAP. VIII. _Of the Soul or Tincture of_ Tin. Good _Jupiter_ possesses almost the mean or middle place between Metals, it being not too hot, nor too cold, not too warm, nor too moist, it hath no excess of _Mercury_, nor of Salt, and it hath the least of Sulphur in it; it is found to be white in Colour, yet one exceeds the other in the three Principles, as it is evidently found in its dissection, the right and true discovery of Nature. It is generated of such a composition and mixture of the three first Principles, being operated, coagulated into a Metal, and brought to the ripeness of perfection. _Jupiter_ is a God of Peace, a Lord of Goodness, a Ruler and Possessor of the middle Region; as concerning its State, Essence, Function, Virtue, Form and Substance; for it holds the mean; no special Disease can happen, that _Jupiter_ should cause any remarkable damage, if its Medicine be used a little at once, not too much in quantity; it is likewise thought needless, where its Medicines are not required, that they should be administred in strange cases with a just Call, but we should rather abide by those, where the Body and its Disease have an equal temper with the superiour Stars and their assistance, in vertue, power, and operation, and so accord together in their juncture, that there is not found the least contrariety in the Operation, nor in the Operative Nature.
