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.

69. The Stinking Menstruum for the dissolution of the Calx of Gold and Silver, in order to the reducing them into Argent vive. Cap. 15. Clav. Pag. 299. Vol. 3. Th. Chym.

TAke of Vitriol two Pounds, of Salt Peter one Pound, of Cinabar three Ounces (I do not understand by what Error Cinabar has crept in among the other Ingredients of this Menstru∣um, for it is a constitutive not of this, but of the following Menstruum for the dissolving of the Philosophers Stone; especially Lully himself, in Cap. 20. Claviculae, speaking of the extracting of Mercury from a perfect Body, having made no mention of Cinabar, whereas notwith∣standing in the same place he gave a Description of this Menstruum in these few Words, saying: Put of our stinking Menstrual, made of two parts of red Vitriol, and one of Salt Peter, and let the aforesaid Menstruum be first distilled seven times, and well recti∣fy'd) let the Vitriol be rubified and pulverized, then put in the Salt Peter and Cinabar, and grind all together, then put the Matter in fit Vessels well luted to be distill'd; let it be distill'd first with a gentle Fire as the Work requires, and as they know how that have done it: Let this Water be distill'd very often, casting away the Faeces which remain at the bottom of the Cu∣curbit, and so it will be your best distilled Menstruum.

Sometimes they added common Vitriol to the Azoquean Vitriol and Nitre: It is thus done.
