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.

To prepare a most Excellent Medicine with this Mercurial Water, proceed thus:

TAke of the afore-said Mercurial {water}, and of Spirit of Wine distilled three times upon Honey, and then rectified upon Salt of Tartar, of each equal parts; distil them together, until they be well united: Then to six parts of this Menstruum put one part of a Spungy Calx of ☉, digest them toge∣ther, until the ☉ is totally dissolved, except a little white Earth, which will remain in the bottom. Then distill in a Retort in

Sand, and cohobate so often, until the ☉ come over into the Receiver. Then sepa∣rate it, by distilling in a Cucurbite, and there will remain a red Oyl like a Ruby in the bottom; whereof one drop in some fit Vehicle, is admirable for Health. This dis∣solution of ☉ hath a most Odoriferous scent, better than Amber and Musk.
