THE  THEATROPHONE.
____

    We are now threatened with the "theatrophone," an invention which is probably not unknown in England and America, says a Paris letter. Two electricians have, it appears, asked the authorization of the Paris municipal council for the putting down of a line of telegraphic cables in the municipal sewers. These cables comprise the marvelous apparatus known as the "theatrophone," which is said to give musical and dramatic compositions, sound for sound and word for word. Dramatic authors and composers are already beginning to shudder at the contemplation of the consequences which will be brought about by the new scientific abomination as regards their artistic property.
