Title
[D8547ZAG], Letter from Thomas Alva Edison to Edward Hibberd Johnson, June 1885
Editor's Notes
[SELECTABLE; TAE autograph description of transmitter expts. 2 pgs.] After a detailed recount of his experiment, TAE asks Johnson's advice on what to do "to develop the bug?" "platina cannot be roughened in the presence of mercury." [Marg.: "I should let it ground? over until tomorrow & then talk on it again for a half hour. If that does not settle its hash--then you have done it. I think you have any way as it is a more severe test than I have ever put them to successfully." EMJ]
