The preparation of a very good vinegar out of certain vegetables which are to be found every where, which may be compared to that which comes out of France, and in a great abundance, whereof two rundlets of nine Gallons do not exceed the price of one Royal. [A Royal or Imperial is 4 _s._ 6 _d._] The promoting of the ripening of wines of the cold countries of Europe (a very few that are very cold being exempted) that they may yield very good sweet and durable wines, whereas otherwise they could come to no maturity, being very like to those which hotter countries yield. A certain secret way of carrying wines from mountainous places, where carts, ships, and other commodities are wanting, where the carrying of ten pipes, doth not exceed the price of one pipe otherwise carryed, so that by this means, outlandish wines may be brought to any place with great profit. A very good and easie preparation of verdegrease out of copper, whereof one pound doth not exceed the price of six stivers. A new and compendious distillation of vinegar, of which a rundlet of eighteen gallons doth not exceed the price of half a ryal, with which many things may be done, especially the crystallizing of verdegrease, of which one pound prepared after this manner, doth not also exceed the price of half a Royal. A compendious and very easie way of distilling a very strong spirit of urin, and that without any cost and pains, so that twenty or thirty pints shall not exceed the price of one royal, being very excellent in medicine, Alchimy and Mechanique affairs, by the help whereof a most beautiful blew vitriol may be made out of copper, being very profitable in Alchimy and medicine, making silver so fusible, that by the help thereof, glass vessels, as basons, dishes, and candlesticks, _&c._ may be so guilded as to be taken for silver. A way of distilling the spirit of salt in a great quantity, and that with small costs, so that one pound thereof will scarce exceed the price of six stivers being very excellent in Alchymy, Medicine, and other Arts; especially for the doing of these following things, _viz._ the separation of gold from silver without hurt to the Cups or other things, also the solution and separation of gold mixt with copper and silver by the force of precipitation, where the _Menstruum_ that is preserved, may again be used for the same uses, which separation is the easiest of all other humid separations, whereby gold is reduced to the highest degree. The separation of volatile sparkling gold out of sand, _&c._ very profitable, without which otherwise it could never be separated, neither by the help of Washing, nor by Mercury, nor by the force of Melting.
