In the same manner as was taught of Zinck, there may be out of lead also distilled a subtle spirit and a sweet oyl, and it is done thus: Pour strong vinegar upon _Minium_, or any other calx of lead, which is made _per se_, and not with sulphur, let it digest and dissolve in sand or warm ashes, so long till the vinegar be coloured yellow by the lead, and turned quite sweet. Then pour off the clear solution, and pour on other vinegar, and let this likewise dissolve, and this repeat so often, till the vinegar will dissolve no more, nor grow sweet; then take all these solutions, and evaporate all the moisture, and there will remain a thick sweet yellow liquor, like unto honey, if the vinegar was not distilled, but if it was distilled and made clear, then no liquor remaineth, but only a white sweet salt. This liquor or salt may be distilled after the same manner as was taught with the Zinck, and there will come over not only a penetrating subtle spirit, but also a yellow oyl, which will not be much, but very effectual, in all the same uses, as of the spirit, and oyl of the Zinck was taught. N. B. This is to be observed, that for to make this spirit and oyl, you need no distilled spirit, but that it may be done as well with undistilled vinegar, and the undistilled yields more spirit than the distilled. But if you look for a white and clear salt, then the vineger must be distilled, else it doth not shoot into crystals, but remaineth a yellow liquor like unto honey, and it is also needless to make the solution in glasses, and by digestion continued for a long time, but it may as well be done in a glazed pot, _viz._ pouring the vinegar upon the Mineum in the pot, and boyling it on a coal fire; for you need not fear that any thing of the vinegar will evaporate, in regard that the lead keeps all the spirits, and lets only go an unsavory phlegm. You must also continually stir the lead about with a wooden spatulla, else it would turn to a hard stone, and would not dissolve: the same must be done also when the solution is done in glasses; and the solution after this way may be done in three or four hours: and when both kind of solutions are done, there will be no difference betwixt them, and I think it providently done not to spend a whole day about that which may be done in an hour. And if you will have this spirit and oyl better and more effectual, you may mix ℥ i. of crude Tartar made into powder with ℔ j. of dissolved and purified lead, and so distil it after the same manner as you do distil it by it self, and you will get a much subtler spirit and a better oyl than if it were made alone by it self. _To distil a subtile spirit and oyl out of crude Tartar._
