THE FOUNTAIN OF FIRE.
To six ounces of water in an earthenware dish add by degrees one ounce of sulphuric acid (dangerous), and then three quarters of an ounce of granulated zinc with three or four large grains of phosphorus. These form a gas, amidst much effervescence, take fire and kindle the entire surface, coruscations and spirts of flame leaping out swiftly and most brilliantly; while a beautiful column of smoke will rise above the blue flames.
Note.—Always cut phosphorus under water, and, if burnt by it, apply hartshorn spirits.
