It burns with a pale-blue flame, and in burning gives off fumes possessed of a strong pun- gent characteristic smell. 3. Phosphorus is a yellowish waxy substance of a peculiar smell, which smokes in the air, shines in the dark, takes fire by mere rubbing, and burns with a large bright flume and much white smoke. Like sulphur, it exists in all plants and animals, though in comparatively small quantity. Like sulphur, also, it is employed largely in the arts, especially in the manufacture of lucifer matches. 4. Hydrogen.—If oil of vitriol (sulphuric acid) be mixed Eig. with twice its bulk of water, and be then poured upon iron filings, or upon small pieces of zinc, the mixture will speedily begin to boil up, and bubbles of gas will rise to the surface of the liquid in great abundance. These are bubbles of hydrogen gas. 1*.
