Photographing By Fireflies' Light

Experimente have been made in photographing by the light oí flreflies. A large number of them were placed ia a small box and confined by a netting. The box waa provided with sensitiva plates and in some instances covered closely in order to discover the power of the light emitted by these insects. It was found that they have a quality not unlike the X-rays, and the plates that were closely covered showed unmistakable evidences of a photographic procesa.
