[N303122], Technical Note, Francis Robbins Upton, March 30th, 1880

Item

Abstract

in the midst of undated lamp tests, probably from March, that seem to be include current regulation, following TAE note on best conditions: [this may well be Upton taking notes on what TAE wants] I am seeking to account for the irregularities in the lamp. I though perhaps the lamps might lower their resistance after a time. It may possibly be int he clamps leading to the lamp.
