    and distilled with an equal quantity of the whole; of corrosive sublimate, an insipid liquor first comes over, and then white vapours, which condense. into a transparent liquor, that emits.a considerable quantity of vapours, by mere exposure to the air. This is the smoking liquor of Libavius; appearing to bean OXYGENATED MurRraTeE OF TIN. It is dissolved by the Oxi-muriatic Acid with ve- hemence, and when the Acid is highly concentrated, a magma is obtained, resembling Pitch, which har- dens in time. It is dissolved in the common J4qua-fortis, pre- pared with Salt-petre of the first boiling, for the composition for scarlet dye, from Cochinelle. ‘This. solution often disappoints, from the variable pro- portions ofthe muriate of Soda, and nitrate of Pot- ash ; when it contains too little muriate, a precipi- tate falls; and whenthe Acid is in excess, it affords. an obscure colour. ‘The most accurate proportions. for a good solvent of Tin, are two. parts of nitr! Cy and oneof muriatic Acid. ; It islikewise slightly soluble in the vegetable Acids. Combined with Sulphur, it forms SULPHURET OF. Tin, or durum Musivum, or Mosaic Gold. Eight ounces of ‘Pinand of Mercury being amalgamated to- gether, are put ina mattrass with six ounces of sul-. phur and four of muriate of Ammoniac ; the bottom. of the mattrass being ignited, the sulphuret sublimes 3, and if the heatis such as tomake the mixture take fire, - it is sublimed of a dazzling colour ina large hexago- nal
