A companion piece to Nikola Tesla: Lecture Before The New York
Academy of Sciences, this paper was read in absentia before an 1898 meeting of The
American Electro-Therapeutic Association. It provides additional information about the
construction and use of Tesla's New York oscillator as well as other smaller devices. Also
included are comments on possible applications for high-frequency currents by the medical profession
and Tesla's personal observations of the effects "when a person is subjected to the
action of such a coil."
