Nikola Tesla, at New York.
Nikola Tesla was the attraction at the Academy of Science April 6th, when he explained several of his discoveries and intimated the direction of the experiments upon which he is now engaged. Mr. Tesla exhibited a new electrical oscillator, based upon a discovery made by him six years ago. Mr. Tesla announced that the manufacture of ozone and other chemical products now attained by costly processes may be done economically and cheaply by the vibrations produced by this apparatus. He said it furnished an ideal instrument for the production of the Rontgen rays. Its advent means the abolition of many devices of older design, particularly, Mr. Tesla said, of the use of the induction coil. Upon the subject of the Rontgen rays, Mr. Tesla announced that he had made two important discoveries. The first is a powerful source in an electric arc under certain conditions. The second is the deflection of the rays by a magnet, the fact needed to establish the identity of the Rontgen ray and the ray discovered by Lenard in 1891. Mr. Tesla said that in 1894 he himself was investigating the actinic action of the phosphorescent bodies and observed the Rontgen rays, but did not recognize them. He said that ever since Rontgen's announcement of his discovery scientists have been endeavoring to establish the identity between the Rontgen and Lenard rays by deflecting them by a magnet. The deflection, however, was so slight that the finest instruments could not record it. Mr. Tesla tried for a long time and failed. A (sic) last he invevted (sic) an instrument by the aid of which, he said, a boy could perform the experiment. Mr. Tesla showed diagrams and designs tending to prove his theory that Rontgen rays were formed by streams of minute electrified particles of matter projected from the bulb at an extreme velocity.
