A greyish matter remains after the detonation, and this is what we call liver of antimony. It contains a fixed nitre, a vitriolated tartar, and the reguline part of antimony vitrified.
*The principal use the Chemists make of antimony is to separate gold from the other metals. All metals, gold excepted, have a greater affinity with sulphur than the reguline

part of antimony. As to gold, it is incapable of contracting any union with sulphur. If therefore I have a mass compounded of various metals, and want to get the gold out, I melt it with antimony, and as soon as it flows, every thing in the mass which is not gold, unites with the sulphur, in or of the antimony, and causes two separations, that of the sulphur of antimony from its reguline part, and that of the gold from the metals with which it was mixed: This produces two new combinations. The metals and the sulphur, in fusion, being lighter, rise to the surface; and the gold and the reguline part of antimony being heaviest, the combination of them sinks to the bottom. Now the business is to part these two, and to this purpose, I expose the combination to a degree of fire, capable of dissipating into vapors all the semi-metal the mass contains. The reguline being volatile, goes off by the great heat, and my gold remains pure and fixed in my crucible.
*As to the antimonial wine, made by the essence of antimony, that is, by impregnating the most generous white wine, with the minims or lests of antimony, which the physicians have found out, it is not the part of a chemist to speak of that; and therefore, I shall only observe to you, that it is the best vomit, the best purge, and the best thing for

a sweat, in the world. I will tell you, good Sir, what I heard an eminent Doctor say of it. — Affirmo sanctissime, nihil inde melius, nihil tutius, nihil efficacius, deprehendi unquam, quam tritum illum, ac simplicem vini automonialis infusum ex vino albo generoso, aromate aliquo stomachico adjecto. Epotus largiter maximas movit vomitiones, in minuta tantùm quantitate, ad guttas puta viginta, aut triginta, adhibitus sudores elicit benignos; paulo tamen majorae aleum solvit leniter. Medicamentum, paratu quidem facillimum, at viribus maximum.—And therefore, good Sir, when any thing ails you, let me recommend the antimonial wine to you. Thirty drops will sweat you effectually. About forty or fifty purges in a happy manner.
*But as to the second semi-metal
