Title
[D8230ZCN], Letter from Francis Robbins Upton to Thomas Alva Edison, November 16th, 1882
Editor's Notes
For last ten days we've been mixing new isolated lamps with higher economy lamps, about 1/3 isolated. "We are trying expeirments constantly in every department to see if we can find the trouble. I think it is in the carbonizing and Lawon is going to try #97 again."
