14, '96. Prof. Elihu Thomson, of the Thomson-Houston Electric Com- pany, described experiments to determine the practicability of making stereoscopic pictures by X-rays. A solid object may be considered as composed of points which are at different dis- tances from the eye. By monocular vision, the solidity of an object is not assured. However, by the use of both eyes, the objects appear less flat. The experimenter used, as the differ- ent objects, a mouse, also metal wires twisted together, and..., again, a block of wood having projecting nails. In order to produce a stereoscopic picture with X-rays, he took a sciagraph in the ordinary way. He then caused the relative displacement of the discharge-tube and the object, and took another sciagraph. By mounting the two sciagraphs in a stereoscope, he found that the effect was as expected, and in the case especially of the skeleton of the mouse, it was very curious, less like a shadow picture and more like the real object. The picture was more realistic, as in the well known stereoscope for viewing photo- graphs.
