Indeed, In-deed, the new Bittina machine n neu the human voice with sur prising clearneM and perfect sonority, so-nority, and with snch force of sound that It can be plainly heard by all the byttaudcra without need cf placing the trumps t to the ear. As in the apparatus of the phonograph and tliegrapbophoncof Jdlson, the modulations of the voice are noted on thu dial by the sonorous disk by means of nee lie points, with the difference that a quantity of needle points, arranged to form ras, gather the oscillations from various points of the sonorous disk to a common center, whence to transmit them together to the cj Under.
