[LB019399], Letter from Thomas Alva Edison to Societe Generale des Telephones, November 19th, 1884
Editor's Notes
The two letters of 15th & 18th insts addressed to me by your Mr Benlham did not reach me in time to allow of my replying to it before he left today for Paris.##There is no secret about the making of lamp Black for carbon. You simply take ordinary oil lamps cut a V in the Cotton wick so that when the lamp is lighted thus & turned high so as to make the lamp smoke heavily & the particles of lamp black are attracted to the lamp chimney great care must be exercised in selecting the carbon thus obtained. Only the very blackest should be used and any having the slightest possible tinge should be rejected.##I think you will have some trouble in getting good results at first. I have only one man who can make the Buttons in a satisfactory manner & he has attained efficiency simply by constant work.
