Tesla
NIKOLA, an American electrical inventor; born in Smiljan, Austria-Hungary, in 1857; studied engineering in the Ecole Polytechnique, Paris; and in 1884 came to the United States, and for several years was employed at Edison's laboratory, near Orange, N. J.
He then opened a laboratory of his own.
In 1888 he completed his discovery of the rotating magnetic fluid by the invention of the rotary field-motor, the multiphase system of which is used in the 80,000 horse power plant built to transmit the water power of Niagara Falls to Buffalo and other cities. He invented many methods and appliances for the use of electricity, among them the production of efficient light from lamps without filaments, and the production and transmission of power and intelligence without wires. Among his wonderful inventions is that of the electrical oscillator, by which he claimed the electric current can be received from its source and given an intensity which will enable a copper wire to carry 50,000 horse-power across the ocean. In November, 1898, Tesla announced the discovery of, and on May 1, 1900, patented, a method of transmitting electrical energy without wires. TESTING CLAUSE ain. Shell small and ear-shaped, placed at hinder extremity of the body which is elongated, broadest behind, tapering toward the head. The species are subterranean in habit, feeding on earthworms, and visiting the surface only at night. During the winter and in long periods of drought they form a sort of cocoon in the ground by the exudation of mucous; if this be broken away the cocoon in the ground by the exudation animal may be seen in its thin, opaque, white mantle, which rapidly contracts till it extends but a little_way beyond the margin of the shell. Fossil species two, from Tertiary strata.
