Aquila praecipitata.

1. The purgation of Vitriol.

REcip. Of the best blew Hungarian Vi∣triol sixteen lb. put it into a glazed pot, poure on it cleare Fountaine or distill'd raine-water, boyle away a third part of it, filter or straine it into a jar-glasse, set this strained liquor into a moist sand to crystalli∣zing, poure the water on againe, let it boile as formerly, iterate it so long as any Chri∣stals will shoot, then all its venemous qua∣lity is gone. In like manner let the pulverised Salt-Niter be dissolv'd, and be purged, as you heard about the Vitriol.

2. Purgation of Sal Armonicke.

REcip. Of Sal Ammonick, of calcined Tartar, ana lb i. sublime these twice or thrice in ashes.

Aquafort.

REcip. Of the above prepared Vitriol, and rubified lb ii. of the above said pre∣pared Niter, and well exiccated at the Sun lb i. mix these being pulverised, distill gently at first, then increase your fire, let all the Spirits come over.

3. To purge this Aquafort.

REcip. Of this Aquafort ℥ ii or ℥ ii ss dis∣solve it in the thinnest Lamins of fine Lune ʒ ii. which being disolved, put it alto∣gether into a glass; the feces of it being set∣led, cant off the water, let none of the mat∣ter come after. Thus is the Aquafort purged. Of this Aquafort lb i. in which dissolve one graine of the salt Ammonick, prepared afore, distill it gently in a Balmy, then you have the prepared Arcanum Regis, or T R.

4. Purgation of Mercury.

POure hot water on calx vive, shake it, coole and settle, filtrate the water, and distill it hot into Flint-ashes, which if this be setled, then filter it. In this lie made of Calx vive, and ashes of Flints, Mercury must be boyled a sixth or seventh time, and that which boyleth away, must be applyed with fresh Lixivium. In like manner let Mercury be boyled a fourth time in salt and distill'd Vineger, so that the salt be covered with blackness, and the Vineger being evapora∣ted, fresh Vineger to be poured on: At last let it be wash'd a third time with hot wa∣ter, and dryed, then it is fit for subliming, praecipitating, and for other businesses.

5. Purgation of Antimony.

REcip. Of powder of Antimony, of purged Sal-Niter, of Calcined Tartar

ana lb ss. Melt it; thus melted, cast it into horne, which being cold, take off the Regu∣lus, it breaketh freely.

1. ℞. Of Regulus of Antimony ℥ i. grind it small, imbibe in a jar-glasse six times with Aqua Regis, dissolve it in it, reserve that which is dissolved in hot ashes.

2. ℞. Of the best Gold, laminated very thinly ℥ ss. dissolve it apart in a jar-glasse in ℥ i. of Aqua Regis. Let it stand.

3. ℞. Of purged Mercury ℥ iii. dissolve it in a well luted glass body upon warm ashes, pouring on it one pound of Aqua Regis. Put these three dissolutions into a well luted cu∣curbit, still it a sixth or seventh time in hot sand per Alembicum; that which is di∣still'd must alwaies be put on againe. At last increase the fire, and let all come over. Then take out the remaining matter, and reduce

it to an Alcohol on a stone, and reverberate it under a muffle, rule it with a gentle fire; the Mercury will look black, and then of se∣verall colours. Continue the reverberation, and rubifye it, and let all the spirit of Aqua Regis be gone. Then wash it with warm water, to take off all its saltness. Pulverise this Mercury well, poure on it of the best rectified spirit of Wine, let it stand over it three fingers; Standing in a warm place for three daies, and shake three times a day, then separate it.

At last poure on the pulverised Mercury of the best distill'd Rose-water, aromatized with Mosch, let it stand also in a warm place for three daies, shaking it thrice a day, sepa∣rate gently unto a driness, it will be a con∣cin praecipitated Aquila, alias, a purging mercurial essence.
