to such raw or unripe metals, return into your mothers womb, and stay there the due time, till you have attained there to perfect ripeness, for you were taken thence too soon against my will. Further, out of this liquor there may be made a good borras to reduce the metals thereby. There may be made also with this liquor fair glased and firm colours upon earthen vessels like unto Porcellan or China. Also by boyling it with water, a tender impalpable snow-white earth may be precipitated out of it, whereof there may be made vessels like unto Porcellan. Many other useful things may be brought to pass thereby in mechanical businesses, needless here to relate. Also the unripe and volatile minerals may be fixed and ripened thereby, so that not only they may be the fitter to be used in Physick, but also the volatile gold and silver contained in them may be saved thereby, whereof more in the fourth part. N. B. Hither belongs also the process of the spirit of lead, Virgins-milk and Dragons blood. _Of the spirit of urine and of the volatile spirit of salt Armoniack._ Out of urine or salt Armoniack, a powerful and penetrating spirit may be made several wayes, which not only is to be used in phisick for many diseases, but is also found very useful in mechanical and chymical operations, as followeth. Take of the urine of sound men living chast, gather a good quantity together in a wooden vessel, let it stand for its time to putrefy, and distil a spirit thereof, which afterward in a great glass retort with a wide neck must be rectified from calcined tartar, and still that which cometh over first, may be saved by it self, and so the second and third also, the strongest may be used for the preparing of metallical medicines, and the weaker for a medicine alone by its self, or else mingled with fit vehicles: The salt which in the rectification cometh over with the strongest spirit; may be put to the weakest, to make it the stronger, or else it may be saved by it self in a good strong glass. But because the spirit of urine is tedious to make, therefore I will shew, how to get it easier out of salt Armoniack. The preparation is thus.
