DAZZLING LIGHT.
Suspend a bullet of antimony in a jar of chlorine gas, in which, after the lapse of many minutes, it will acquire a red heat, and slowly burn away. Then pour finely-divided metallic antimony into a tall jar containing chlorine; the metal instantly ignites, and falls to the bottom as a fiery shower; yet the nature of the chemical action in both these experiments is the same. Make a piece of thick iron wire white hot, and insert it in a large tube containing vapour of sulphur, made by boiling some brimstone in the bottom of the tube; the white-hot iron will catch fire, and burn away like wax, and with intense brilliancy, in the sulphur vapour. The iron must first be raised to an intensely white heat, or it will not burn under these conditions.
