Title

[D8020ZBY], Letter from Simon Newcomb to Thomas Alva Edison, February 25th, 1880

Editor's Notes

Just saw that TAE has patented the idea he had about using finely divided metals with nonconductor. Have you tried putting cheap, not highly conductive metal in thin calcium tube? Marg: "Yes tried that but there is too much radiating surface so that there is no economy."
