Editor's Notes
[Letterhead: E.T. Gilliland] Received yours of 5 April; will make model you suggest.###Also received letter you wrote to Johnson; Johnson says the cutout where you show compound to disintegrate is Greenfield's patent owned by Bergmann Co.; am making another one where compound changes resistance.###Made 19 lamps; all worked well; Batchelor tried to make them miss but couldn't; used peroxide lead & mucilage made into a paste causing it to arc, positive; your idea serves another purpose bringing resistance down, dispensing with device in station; [Provides drawing of another idea--soldering the lamp arcs in the first tube and soldering the wires together].###Hamilton has made a good condenser using tissue paper normally used to wrap silverware to prevent tarnish.
