A choice collection of rare secrets and experiments in philosophy as also rare and unheard-of medicines, menstruums and alkahests : with the true secret of volatilizing the fixt salt of tartar / collected and experimented by the honourable and truly learned Sir Kenelm Digby, Kt., Chancellour to Her Majesty the Queen-Mother ; hitherto kept secret since his decease, but now published for the good and benefit of the publick by George Hartman.

Monsieur Toysonnier wrought thus:

TAke fresh Urine of young Boys, fill one Pot with it, and evaporate it away, next Morning put on fresh, and evaporate; do thus three or four days, then evaporate to a Honey, and that you feel a Ponticifie smoak from it, then cease, and put your Honey into an earthen Vessel, and expose it

to Celifie in the Air. As soon as it is cold, it will be hard, but the Air will resolve it: Make thus what quantity of Honey you please: Celifie them four days, then have another earthen Pot, covered with a rever∣sed one that hath a hole in the bottom, fasten thereon a neck of a Cucurbite of Glass, ten or twelve inches long, upon which a Retort, with the bottom out for a head, to which fasten a great ballon. He did put fifteen pound of Honey into his Pot, and with a gentle fire first distilled off the Spirit and Vo∣latile Salt; these be put upon new Honey, and in Balneo distilled a purer Spirit and Vo∣latile Salt; (the flegm that followed, if put upon new Honey, will become pure Spirit and Salt) draw the fixed Salt out of all the Caput Mortuums; put ℥xij. of the Spirit up∣on as much pure Spirit of Wine, and it will coagulate it all into a perfect dry Salt: Min∣gle these ℥xxiv. of Volatile Salt with ℥vj. of Salt of Wine, ℥iij. of Volatile Salt of Urine, and ℥iv. of ☿ Precipitate, and put them in∣to a Body with Head, Limbeck, and Re∣ceiver, and Sublime with gentle heat: Part cometh over in Spirit, and part riseth in Salt. Take ℥xiv. of Salt, and vi••. of Spirit, and ℥ss. of Calx of ☽, and distill with exceed∣ing gentle heat in a Body and Head with a Receiver, a liquid Spirit will come over,

and a white Salt Sublime into the head: Put all back upon the Cake of ☽, and distill as before. He hath now ••••eated this Worst eleven times; at the first, the Spirit and Salt were ten days rising from the ☽, but after∣wards seven or eight: The junctures were all perfectly shut, yet above half of the Vo∣latile Matter was vanished. The Salt of Wine was made thus: (Spanish Wine gave none, but French did pretty store.) After you have drawn off the Spirit and the flegm, evaporate the residue (very gently) usque ad pelliculam, then set in a cold place, and in fifteen days there were many Crystals in it; wash these with the flegm of the Wine, from the blackness and foulness that is upon them. The ☿ Precipitate was made thus: Dissolve ℥iv. of ☿ in ℥x. of A. F. made of two parts of Vitriol, and one of Nitre. Ex∣tend the solution, by pouring a great quan∣tity (eight or ten Pints) of fair {water} upon it; then pour upon it a Lixivium made of the fixed Salt of Wine and fair {water}. He made his Lixivium of ℥iv. of fixed Salt, and but one of the ☿•• Precipitate; wherefore he poured upon the Liquor that he poured off from the Precipitate about half a pint of the Spirit of Wine, and then the ☿ Precipitated all down. Take both the Precipitates, and wash them a little from the Spirits of the A. F.
