Title
[D7941ZGM], Letter from Thomas Alva Edison to Edison Telephone Co of London Ltd, October 20th, 1879
Editor's Notes
"After reading Johnson's book consider his report sound except perhaps combination claims induction coil. In provisional I speak of combination of transmitter with coil in final specification I more fully describe combination. The words well known ways means circuit contacts in primary. This point will bear my analysis."
