Title
[D8123ZBE], Letter from Francis Robbins Upton to Thomas Alva Edison, April 25th, 1881
Editor's Notes
An electrical short and resulting insulation fire in motor running pumps led to breakage of fall tubes of 18 pumps and mercury flooded 150 lamps. Sent 1964 A and 556 B lamps into photometer room last week. Wants TAE to personally look at Peters factory; Upton says it's valuable and should buy.
