My Child shall take 10, 12, or 15 pound of _Saturn_, wherein is no mixture of any other Metal; laminate it thin, have in readiness a great Stone Jugg, half full of Vinegar, stop the Jugg very close, set it in a Lukewarm Bath, every three or four days scrape off the calcin'd _Saturn_ from the Plates, and reserve it apart, thus do so long till you have 5 or 6 _l._ of the calcin'd _Saturn_, then grind it very well on a Stone with good distilled Wine-Vinegar, so as you may paint therewith, then take two or three great Stone-pots, therein put the _Calx_ of _Saturn_ which you ground, poure good distilled Wine-Vinegar upon it, that two parts of the Pot be full, stir it well together, stop the Pot close with a polished Glass or Pebble-stone, set the Pots in a Bath, stir it four or five times in a day with a wooden Ladle, lay the Glass or Stone Stopple again over it, make the Bath no hotter than that you may well endure your hand therein, that is, lukewarm; so let it stand fourteen days and nights, then decant that which is clear into another Stone-pot, poure other distilled Vinegar upon the _Calx_ which is not well dissolved, mix them well together, set it 14 days in the Bath, again decant it, and poure other Vinegar upon it as before. This decantation and pouring on continue so long till all the _Calx_ of _Saturn_ be dissolved, then take all the dissolved _Saturn_, set it in a Bath, evaporate the Vinegar by a small fire, the _Saturn_ will become a powder or lump. Or stir it about until it be dry, you have a mass or powder of a dark yellow, or honey colour, then grind the powder again very finely upon a Stone with distilled Vinegar; put it into a stone-pot, stir and mix it well together, set it again into a Bath, which is but lukewarm so let it stand five or six dayes, stir it every day from the top to the bottom with a wooden Ladle, cover it again with the glass-Stopple, then let it cool, poure off that which is dissolved into a great stone pot, poure other Vinegar upon it, mix and stir them well together, set it into the Bath as before, reiterate this decantation and pouring on so often, till no more will dissolve, which try with your tongue, if it be sweet, it is not enough dissolved, or put some of it into a glass-gourd, let it evaporate, if any thing remain, it is not yet all dissolved which would be Gold, and then what remaines in the pot are _Faeces_, and sweet upon the Tongue; if you find any thing in the Gourd, it is not yet all dissolved, then may you poure fresh Vinegar upon it, till all be dissolved, then coagulate it as before, poure other Vinegar upon it, stir it, set it again into the Bath, reiterate this operation of solution and coagulation so long till you find no more _Faeces_ at the bottom, but all be dissolved into a pure clear water, then is _Saturn_ freed from all its Leprousness, Melancholy, _Faeces_, and blackness, being pure and white as Snow, for it is cleansed from all its
