[D8905AAH], Letter from Charles H Mixer to Thomas Alva Edison, January 16th, 1889
Editor's Notes
Department of the Interior, United States Patent Office. Dear Edison, In the year of our Lord 1874 you promised me a set of instruments-- a key, relay and sounder. You gave me at the time a very nice key for which I was duly thankful. Now however I must have a relay of between 20 and 30 ohms. Have you such an instrument to spare? Yr friend Charles H Mixer
