Title
[D8123ZCC], Letter from Francis Robbins Upton to Thomas Alva Edison, May 28th, 1881
Editor's Notes
16-candle lamps have passed 480 hours; two failures. Let two in the engine gang go b/c sat around too much. "The lamps with carbons which were high resistance due to the final heat are all right. They are making a fine curve and their resistance is low."
