INVENTED BY RICHARD S. RHODES, CHICAGO. Medal Awarded at the World's Columbia Expo- The Audiphone is a new instrument made of a peculiar composition, posessing the property of gathering the faintest sounds (somewhat similar to a telephone diaphragm), and conveying them to the auditory nerve, through the medium of the teeth. The external ear has nothing what' ever to do in hearing with this wonderful instrument. Thousands are in use by those who would not do without them for any consideration. It has enabled doctors and lawyers to resume practice, teachers to resume teaching, mothers to hear the voices of their children, thousands to hear their ministers, attend concerts and theatres, and engage in general conversation. Music Is heard perfectly with it when without i, not a note could be distinguished. It is convenient to carry and to use. Ordinary conversation can be heard with ease. In most cases deafness is not detected. Full instructions will be sent with each instrument. The Audiphone is patented throughout the civilized world.
