Abstract
40. The crystal phonopticon
The crystal phonopticon is an arrangement of apparatus whereby illumination characteristics (e.g. such as come from a small portion of any printed page) of variable arrangement, intensity and sequence may be transformed into sound progressions of corresponding variable intensity, arrangement, duration and sequence. It is called the Crystal Phonopticon because by the use of recently discovered crystals, of selenium light impressions are transformed into sound impressions.
