[D8430D], Letter from William Holzer to Thomas Alva Edison, January 10th, 1884

Editor's Notes

Lamps exhausted without applying current with side tube containing cocoanut charcoal. Lamps exhausted & heating bulb with alchohol flame using no current. Lamps with oxide of magnesia on fibre and then carbonized. Now underway TAE's experiment of burnishing the fibres, will carbonize next Monday. Also underway experimet of fixing[?] carbpm tp omsode [part] by dispensing with shank on carbon and applying a paste made of dissolving finest grade Indian ink & securing the carbon to the pplaintum wire without using any carbon, done neatly and quickly. Will try experiment on cementing carbon to wires by using sponge platinum. Experiment of taking lamp that has given long life and patching it will receive prompt attention. Bamboo paper sent out to be carbonized was handed to John Ott to deliver to TAE. Indicator with the platinum wire in ring forms so as to prevent the breaking of the carbon in transporting.
