Abstract

"A young man called at our office about ca couple of weeks ago, and stated that he was engaged in the manufacture of incadescent lamps, and this morning we received from him the enclosed samples of the material he uses for his filament. Thinking it might be interesting to see what some of your would be competitors are using, we sent it to you. It would seem on casual examination that the material is not sufficiently regular to make a filament of uniform resistance, and we therefore doubt its value unles it is heavily plated. ### We should like to have your opinion about it if you think it worth while to write us concerning it. Of course we do not intend your opinion shal be published and shall keep it to ourselves; we desire it merely to show whether we understand what is necessary for a perfect filament." Yours very truly, Paine & Francis [Marginalia: "Ans. Jan 16/88"]
