The Remainder thoügh they could also have casily Resolve d by GnnJing- tyet they thoughr good ro make an Extraft of it by means of their Tbtloso ■phtcil Ocelum, made of Verdigrease, Sulf hur , and a Highly Rettisfd Spirtt ofWtne, by a long Digeßion : Whcreby they gor again a Tir.Eture sufficientlyRed and of very great Vertue. And that little that remain’d, which wasbut very little, they reduccd into a Body by the means of Borax ; but itwanted its du elVeigbt.

’Tis true, faith our Author, that at the first View this Operation ssenistobe gross, requiring much Time and Labour, but little Äre, but wellconsider’d, ’tis highly Admirable, being Assi sied by the wonderful Sah ofthe Air, as the only Catbolick Dijjolvent . And that Salt is by the continualGrindtng Attracted and Intermixr, many othcr Experiments, made bybim about it, have taught him; which he referves for the Publication,bereafter to be made, of the things done in the Gottorpian Laboratory,

The 2 d Experiment ofthe use of this Grindtng, was in a True and GenuinePreparation of the Mercury of Antimony : A Proceß affirm’d not only madeby himselt before bis Trince, but also by the Hands of that very Experienc’dChymifi of the EUclor of Saxony, Johannes Kttnchclius.

The Operation consistsin this; Grind first the Regulus of Antimony into anImpalpable Powder; and to i Tound of it add 2 Poimds of very pure anddry Salt of Tartar , and 8 Ounces of Sal Armoniack ; and mix it well toge-ther. Then moisten it with forne Urine of an Healthy Man, especially" ofone that drinks Wine, if such may be had ; and take care, to have this Mix-ture Ground for a whole Day together without any Intermiffion by two veryflrong young Men; always, if there want Moisture, sprinkling Urine uponit, that it may stand 3 Inches high over it, andClosing it well, keep it inDigeßion for a whole Month, daily stiaking it. And if during that tirne theMass appear to be Dry, pour on more Urine. The Digestion being ended,form the matter into Globales with equal parts of beaten Glafs and Calx vt-ve,and Dry it in th tShade. Of thesr, Extraft the Mercury in mannet follow-ing ;

Lct there be ready an oblong Iron Vessel,likc a Bolt Head, into which pourGold Warer, and dig it into the Ground : Upon it put an Iron Plate withmany Holesinit, and lay thereon the fäid Globales well dry’d; then fit also-an Iron Head, somewhat Flatred, to it, that you may conveniently layCoals thereon, and thus keep a Moderate Fire for 4 Hours, then increase theEure för as many Hours, unto the last. After that, let it Cool, and beware,nottostirihe Vesseldigg’d in the Ground, nor to pour out the Water, be-fore that be altogether Cool’d ; or elfe you will loosc a great deal of the Mer-cury ; ashappen’d, it feems, to our Author, when his Trince, being im-patient of delay, Commanded the Water to be pour’d out before it wasTime : For the Mercury , being by so Strong a Fire refolv’d into Atoms, isto be Coagulated again by Cold.

This Mercury of Antimony our Author Glorieth in, as having Prepared andhandlcd it with his own Hands, and feen it with his own Eyes, after the sinistitDistillation, runningin thebottom ofthe Vessel. Neither doth he care if
