1864 'The New Metal.— Magnesium was discovered by Sir Humphrey Davy in 1807, but remained little else than chemical curiosity until 1862-63, when Mr. Edward Sonstadt patented a series of processes, whereby it may be produced in any quantity.

If the end of a piece of wire be held in the flame of gas or candle, it at once takes fire, and burns gently with a dazzling white light, by which a photograph may be taken with perfection equal to sunshine.
