Summary

Description Woodcut of the use of an early wax cylinder phonograph, or gramophone, for dictation. Although the phonograph was first invented by Thomas A. Edison, the source text says this was a machine called the 'G', invented by Alexander Graham Bell, Chichester A. Bell, and Sumner Tainter. The user turns the cylinder by pumping the treadle, and speaks into the mouthpiece. The recording is played back by replacing the mouthpiece with the 'stethoscope' type earphones lying on the desk. Extra wax cylinders are seen on the desk. Alterations to image: removed caption, which read: "The Gramophone receiving a dictation".
