The deaf are now able to hear i through their bones, thanks to an ! = invention known as the '*' ossiI phone," by C. G. Brown, a scientist and engineer, of London. The ossiphone is based on the knowledge' that the bones of the skull convey the sound waves caught by the ear drums to the department of the brain connected with hearing. The ossiphone has a sound wave conductor fitted into a vulcanite box containing a magnet and some wire coils. A wire from the sound transmitter connects with the sound box, which has sound passages, a microphone of a special kind and some dry cells. The whole apparatus is about the size of a kodak camera, and looks like one. There is a sound passage made to exact and minute calculations.
