[LB001288], Letter from Thomas Alva Edison to William Orton, September 17th, 1877

Editor's Notes

In looking over my old caveats tonight I have found an Acoustic caveat practically the same thing as Dolbear & Bell have, ie a tube, a plate, a permanant magnet, and not battery used, this is on record in the patent office and goes back of both, therefore if Dolbear dont catch him I can, Pope I think has copy of caveat
