An Operation upon Jupiter.

DIstill a Menstruum out of Vitriol and {sal armoniac}, with which make Sulphur naturae Iovis: Make also with the same Menstruum Sulphur nat. ☽, which dissolve into Oyl, and with it insere Sulphur Iovis ad fusibilita∣tem, and then project upon Iupiter.

Dunston thus: Having taken our white Earth, you may putrifie it by it self, or with the Calx of other Metals, and change its co∣lour into a new white or red: Then ferment it with the Oyl of ☉ or ☽, &c.

Riply (in his Viaticum) thus: Calcine ♃ into a most subtil Calx (for in it there is pure ☿, not brought to its full perfection by Nature) which is easily hardened with the Oyl of ☽. Do your Work therefore with Tin (until you are Rich ) because so the Work is easily done, and at small charge.

Lullius (in his Magia Naturalis) thus: Make Sulphur naturae (without which no∣thing can be done) and thus of any Metal (which he directeth to do in a very tedious

way) then incere it with Oyl of Ferment (as in his Pract. Brev. or Sermocinal) until it be fluid; then it is a perfect Medica∣ment.
