Title
[D7937U], Letter from Henry Bentley, Philadelphia Local Telegraph Co to Thomas Alva Edison, March 21st, 1879
Editor's Notes
Sends map of Phila for SLG. Still waiting for TAE to send buttons for trial. Don't delay; Bell telephone's Blake transmitter reportedly has metallic contacts--no carbon--and works well.
