The following item, from the dailies, certainly indicates the nothingness of matter:
A puzzle is now agitating the minds of photographers in Philadelphia. It lies in the fact that in a group of eighteen people, the objects behind the sitters appear in faint outlines, as if the bodies of the sitters were transparent. In some few cases the appearance of the outlines of the doors and panels, against which the people are standing, can be explained on the ground that there was a momentary movement in which the camera caught and reproduced the picture of the object. But the poser is the case of the lady sitting in the centre of the group, in a wicker-work armchair. The twisted outlines of the chair-back are distinctly visible through the neck and body of the sitter, with clear-cut distinctness. The photographer can not understand it, and the Amateur Photographers' Society has tried in vain to solve the mystery. The phenomenon is contrary to the recognized laws of optics, and is believed never to have occurred before.
