Oxygen the Active Agent of the Air.—The burn-ing of substances in air resembles the burning in 0,except that it is never so energetic. It is, indeed, atrue oxidation, and the oxides formed are the sameas those produced in the 0 we prepare. The burn-ing candle gives off C02, sulphur S02, phosphorusP205, the glowing iron which the blacksmith drawsfrom his forge forms scales of Fe304, which flyblazing in every direction under the blows of hishammer.* Comprising about one fifth of the com-mon air, 0 is ever-present, ever-waiting. * Quite in cont
