    The vitriolic acid, affifted by heat, and even by diftillation, diflolves Regulus of Antimony. The nitrous acid likewife-attacks it; but the loin tion can by no art be made clear and limpid: fo that the Re- gulus is only calcined, in a manner, by this acid. The marine acid diflolves it well enough ; but then it muft be exceedingly concentrated, and ap- plied in a peculiar manner, and efpecially by dif- tillation. One of the belt methods of procuring a perfect union between the acid of lea-falt and Re- gulus of Antimony, is to pulverize the latter, mix it with corrofive fublimate, and djft.il the whole. There rifes in the operation a white matter, thick and fcarce fluid, which is no other than the Regu- lus of Antimony united and combined with the acid of lea-falt. xThis compound is extremely corrofive, and is called Butter of Antimony. It is plain that the corrofive fublimate is here de-^ compounded; that the Mercury is revivified, and that the acid which was combined therewith hath quitted it to join the Regulus of Antimony, with which its affinity is greater. This Butter of Anti- mony by repeated diftijlations acquires a conft- -derable degree of fluidity and limpidnefs. . K the acid of nitre be mixed with Butter of An- timony, and the whole diftilled, there riles an acid liquor, or a fort of aqua regis, which ftil] retains fome of the diflblved Regulus, and is called Bezo- ardie Spirit of Nitre. After the diftillation there remains a white matter, from which frefh fpirit of nitre is again abftra&ed, and which being then wafhed with water is called Bezoar Mineral. This Bezoar Mineral is neither fo volatile, nor fo cauftic, as Butter of Antimony; becaufe the nitrous acid hatn not the property of volatilizing metallic fufi- nances, as the marine acid does, and becaufe it remains much more intimately combined with the reguline part.
