How by the help of this liquor to make trees to grow out of metals, with their colours. _Although this process in Physick may be of no great use: yet in regard that to a Chymical Physitian it gives good information of the condition of natural things, and their change. I thought it not amiss to set it down here._ Take of the above described oyl made of sand, pebles or crystals as much as you please, mix therewith a like quantity of the lixivium of Tartar, shake both well together, so that the thick liquor may not be perceived in the lixivium, but be throughly incorporated therewith, both being turned to a thin solution, and then your water is prepared, wherein the metals do grow. The metals must be first dissolved in their proper corrosive _Menstruums_, and the _Menstruum_ must be quite abstracted from thence again, but not too near, that the calx of the metal may not grow red-hot, whereby its growing vertue would be taken from it. Then take it out of the little glass-body, and break it in pieces about the bigness of a pulse, and put them in the above described liquor in a cleer bright glass, that the growing of the metals may be discerned through it; and as soon as the prepared metals are taken out of the glass body, they must be kept from the aire, else they lose their growing vertue. Therefore thus dry they must be broken in pieces, and laid in the bottom of the glass (wherein the liquor is) a fingers breadth one from another asunder, and must not be laid together on a heap. The glass must stand still in a quiet place, and the metal will presently swell in it, and thrust forth some bulks, out of which branches and twigs do grow, so finely, that one shall admire at it; and let none think that this growing serveth only for to please the eye, for some special thing is hid in it; for all sand or pebles, although they be white, invisibly containeth a hidden tincture or golden sulphur, which none without experience will be able to believe; for if for a time you digest the pure filings of lead in it, there will gold come to stick to the outside thereof (which gold may be washed off with water) and the lead will look as if it were gilded. Which gold came from no where else but from the sand or pebles, although they were white and clear, so that it could not be perceived in them. It sheweth also its meliorating vertue, when the metals do grow therein, and for a certain space of time are digested therewith. For it may be seen apparently, that the metals in the growing do increase from this liquor, and attract what is for their turn; which hence also may be perceived, that when but as much as the bigness of a pea groweth therein, it will grow twice or thrice as big, which is worthy to be considered of. Also the pebles or sand-stones are the natural matrixes of metals, and there appeareth a great sympathy between them, especially between the unripe metals and them; as if nature should say
