Music by Telegraph.

Elisha Gray, of Chicago, well known in the electric telegraph world, has succeeded, almost beyond his own anticipations, in perfecting an instrument which will convey sound by electricity over an unbroken current of extraordinary length without the aid of automatic repeaters. In the ordinary transmission of messages over telegraphic wires to points at a long distance, a message is generally repeated by automatic working instruments about every 500 miles, in order to renew the current of electricity. Mr Gray has transmitted sounds, which were distinctly audible at the receiving point, over an unbroken circuit of 2400 miles. It is one of the greatest discoveries made since the early days of Morse. Such noted electricians have long agreed upon, that we know little at present of the possibilities of the future of electric science. The writer has heard rmisie played <jn a small mdedeon. dr piano

The 'apparatus by means of which the accomplished has been named by Mr Gray the telephone, or an instrument designed , for the , purpose of transmitting sound to a distance' It .consists of three general .parts—-the transmitting instrument, tlie, conducting wire, and the apparatus for receiving the sound at that distant point. The, transmitting apparatus consists of a key-board having a number of electro j magnets corresponding with the number of keys on the ,board, to which are attached vibrating tongues or reeds, tuned to a musical scale. Any one of these tongues can be separately .set in motion by depressing the key corresponding to it. Thus a tune may be played by manipulating the keys in the same way,as those.of an ordinary piano or melodeon. The music, produced entirely by electricity, of these notes is so distinctly audible in the next room that, in spite of much talking, there is no difficulty in determining what the manipulator is playing.— Alta California.
