Four books of Johannes Segerus Weidenfeld concerning the secrets of the adepts, or, of the use of Lully's spirit of wine : a practical work, with very great study collected out of the ancient as well as modern fathers of adept philosophy : reconciled together by comparing them one with another, otherwise disagreeing, and in the newest method so aptly digested, that even young practitioners may be able to discern the counterfeit or sophistical preparations of animals, vegetables and minerals, whether for medicines or metals, from true, and so avoid vagabound imposters, and imaginary processes, together with the ruine of estates.

84. The Aqua Mirabilis of Isaacus. Cap. 29. 2 Oper. Min. & pag. 91. Manus Phil.

TAke old Urine, distil with a weak Fire, then a stronger, that whatsoever can, may ascend; rectifie the destillation, taking away all the Fatness or Oyl, till it leaves no Faeces be∣hind it. The Caput Mortuum left in the bottom, calcine the space of two hours, but without fusion of the Salt, draw all the saltness from the calcined Matter, with common Water; evaporate the Liquor to a thin skin, that the Salt may be Cri∣stalized, repeat sometimes, that the Salt may be made most pure, which dissolve in the distilled Urine. Then take of this regenerated Urine six pounds, of distilled Vinegar, and Spirit of (Philosophical) Wine, of each three measures, of Common Salt two pounds, of Sal Armoniack and calcined Tartar, of each half a pound, dissolve them all together into an Aqua Mirabilis.

The like Water almost hath Basilius, but that he distils his through an Alembick; the Description of which followeth.
