A Work Copied out of the Original of Mon∣sieur de la Violette's own Hand, whereof he made great Account.

TAke ℥iiij. of the purest and finest ♃, and ℥viij. Spanish ☿ purified with Salt and Vinegar, make an Amalgama. Then take red Minium and AEs stum of each ℥iiij. Danzick Vitriol lbj. reduced to half a lb. 〈1 page duplicate〉〈1 page duplicate〉

by Calcination, grind and mix these all well together, and put them into a Retort coated, and pour upon it one pound and a half of the following A. F.

Take Vitriol two pound, which reduce to one lb by Calcination, which put into a Retort, and pour upon it a good A. F. made of Vitriol and Nitre, Distill it S. A. and you shall have an A. F. fit for this Work, which having poured upon the said Matter, Distill it off, and it will be very ponderous. Break the Retort (being cold) and you will find on the sides of it, and up∣on the Caput Mortuum, a very red and pon∣derous Sublimate, which take off.

Take the half of the Caput Mortuum, and as much of Bay Salt decrepitated, re∣duce all to a fine Powder with the said Sub∣limate, and then put all into a new Retort, and pour upon it the Distilled A. F. Distill it as before, and the said A. F. will come off very red, and the Sublimate will be more red, and more ponderous than before, and will rise very high at this time. Keep this Water very carefully, break the Retort, and take both the Feces and Sublimate, and re∣duce it to Powder, and Sublime it by it self without A. F. and the Sublimate will mount but upon the surface of the Feces, which separate, and it will have acquired more

redness, and will be almost fixed. Put this Sublimate into the said A. F. and it will dissolve it speedily: Distill or evaporate the A. F. in Sand, and the Sublimate will re∣main in the bottom like a deep-red Oyl. Put into this Oyl ℥iij. of the fixed Sulphur of Vitriol, made according to Art; put it into a Matrass with a short neck, and digest in Sand, until all the moisture is exhaled.

Then take an Amalgama made with one part of ☉ and two parts of ☽ Calcined with Salt, and four parts of Spanish ☿ (washed with Salt and Vinegar;) then squeeze out so much ☿ as you can from the Amalgama, then wash and dry this Amalgama, and pour upon it by little and little of the above-said A. F. let it stand half an hour, then pour on more of the Water as before, and you will see the Amalgama dissolve visibly, and will be reduced to a very red Powder.

Note, that once in half an hour you must pour on some of the said Water, and all will be done in less than half a day. Digest it half a day longer in Sand; then break the Vessel, take out this Precipitate, and melt it with a little Borax, and you shall have ☉ at 24. Carats.

Note, that if you take equal parts of ☉ and ☽ to your Amalgama, you shall have in∣crease yet fourty or fifty per Cent. more.
