The Luminous Writing








Small pieces of tin-foil may be stuck on a flat piece of glass, so as
to represent various fanciful figures. Upon the same principle is the
word LIGHT produced, in luminous characters.

It is formed by the small separations of the tin-foil pasted on a
piece of glass fixed in a frame of baked wood. To use this, the frame
must be held in the hand, and the ball presented to the conductor. The
spark will then be exhibited in the intervals composing the word, from
whence it passes to the hook, and thence to the ground by a chain. The
brilliancy of this is equal to that of the spiral tubes.
