Tesla's Experiments with X Rays

"The Electrical Review" will publish to-day a communication by Nikola Tesla concerning his recent experiments with X rays. He says that the sunburn effects observed in the use of the rays are not due directly to the rays, but to the ozone generated by the rays, and adds: "The ozone, when abundantly produced, attacks the skin and many organic substances most energetically." By the use of perfected oscillators, he asserts, "the production of ozone is so abundant that it is sufficient merely to turn on the current for a few seconds to strongly ozonize the atmosphere of a large hall." He hints at the possible manufacture of fertilizers by the use of the electrical current, and goes on: "If merely fertilizers of the soil could be manufactured in this manner, the benefits to humanity derived therefrom would be incalculable."

The inventor does not think it is possible to make the blind see by means of the X rays, because by means of the rays only the shadow of a small object can be projected. He declares that he cannot confirm some of the experiments reported, and remarks: "When a hand is put before the closed eyes it is easy to distinguish the shadow, much the same as before the light of a candle, but when the tube is inclosed, and all the light from the same excluded, I fall to get such an impression. The latter is, therefore, chiefly due to ordinary light."
