Excerpt from The Telephone: Its History, Construction, Principles, and Uses, With Definite Instructions on the Making of Telephones, (by Which Failure Is Impossible), And to Which Is Added a Chapter on the Phonograph

The word Telephone is derived from two Greek words tele - distant, and phone - voice and so may be applied to any instrument which enables us to hear the voice at a further distance than it can be heard by ordinary means.

The name is specially applicable to the instrument just invented by Dr. Bell, by means of which the voice is repeated at the distance of hundreds of miles.
