by TESLA, Nikola (1856-1943).
Paris :: Societe Francaise de Physique, 1892., 1892. 8vo. pp. 62-128. 33 figures (showing Tesla's electric bulbs and schematics for other electrical devices). Whole volume: 4 issues bound together. 466, 63, [1] pp. Contemporary green calf-backed marbled boards, gilt-stamped spine; rubbed. Very good. First printing in French. This work begins (in French) "Gentlemen, some time ago I had the honor of bringing to the American Institute of Electrical Engineers the results I had arrived at in a new direction. I will not dwell on the experiences already described, except to complete or express more clearly some ideas that I have put forward previously, and also with the aim of making a homogeneous whole of the presentation of my work on this subject. / My research, as you know, concerns alternating currents, and more especially those of high voltage and high frequency. To what extent is high frequency essential?" – Tesla. / Mr. Jules Joubert (1834-1910) announces on the meeting of February 18, 1892, a lecture by Nikola Tesla: "Mr. President presents to the Members of the two Societies (1) the American engineer Mr. Tesla, who was kind enough to come to France to show us his great experiments on the effects produced by high frequency alternators". / "Mr. Tesla explains very briefly that he has created an alternator giving 10,000 to 20,000 alternations per second. The current from this alternator passes into the primary circuit of a small, perfectly insulated induction coil immersed in the oil. The terminals of the secondary coil then make it possible to collect electricity under high voltages, with very rapid alternations. We will designate this coil by the letter A in the description of the experiments". – Joubert. / On February 3, 1892, Nikola Tesla delivered a lecture before the Institution of Electrical Engineers in London concerning his then current work on alternating currents. His talk was titled "Experiments with alternate Currents of High Potential and High Frequency". The talk was published the same year in book form by W. J. Johnson in New York. On February 18, about two weeks later, Tesla appeared before the Societe Francaise de Physique in Paris where he addressed the Society, in French, concerning his work and delivered to them the same paper which he had presented in London. In French, his paper was titled "Experiences les Courant Alternatifs de Grande Frequence et de la Haute Tension". This paper and his accompanying remarks are found in Seance de la Societe Francaise de Physique (Janvier – Avril 1892) published in Paris that same year, at pages 58 – 62 (remarks) and 62 – 128 (paper). NOTE: Includes: Pierre and Marie Curie, « Sur la conductibilite des dielectriques solides. » [pp. 261-263].
