Do not the ores of metals imbibe this inflammable principle from the ignited charcoal in a surnace, and thereby become metals? for metals will burn and let out this inflammable principle, like any other combustible body. As fire repels itself, this principle can be forced out of the metal by great or continued ignition, and the metal again becomes an ore, or, which is the fame thing, a calx: to this calx I conceive the vitriolic acid to have a stronger affinity; and, therefore, when iron is attacked by that acid, diluted, the inflammable principle is dislodged from the iron, and rises, with water, in the character of inflammable air, while the acid is seizing the calx, and forming with it the falt of iron (green copperas). This copperas consists of the calx of iron united with vitriolic acid, and if distilled in the common apparatus, fig. if Plate XV. yields vital air, and the iron becomes revived, and is found at the bottom of the retort. Iron, also, acquiring more rust when exposed in large towns than on mountains, or in the country, from the acidity of smoke; that acidity qualifies the calx (rust) to produce vital air, when assisted with a little vitriolic acid, in the above apparatus. Do not these prove that vital air may be generated by acid and fire, as well as attracted from the atmosphere? All other metals are liable to nearly the fame routine of composition and decomposition, and therefore Jixtjire may be faid to be one of their most important ingredients. Metals are all susible, though at very different temperatures, and assume a crystallized figure in cooling; for if a hole be opened in the bottom of the melting-pot, after the surface of the metal has become solid, and t...
