[D7941ZDV], Letter from Edward Hibberd Johnson to Thomas Alva Edison, September 6th, 1879

Item

Abstract

His inertia transmitter too unreliable & often gets feedback vibrations from receiver. Gets good results with the 4 arm pattern phones TAE sent; used one to dictate story from "Times" office to typeset room. Asked by Times to adapt typesetting machine to telephone for next session Parliament. Bell tried this--"bitter failure." Sorry that TAE has gone for whispering phones by making more sensitive but less perfect trans. Send 12 of old style carbon trans & will produce different report than WU giving. Writing micro- phone/teleph pamphlet; send more info--refuting DuMoncel. Exhibit exchange for press today. Later: demo great success. Describes demo & those present. Forget the inertia teleph: "I want only 1st class lampblack carbon transmitters."
