Title
[N103071], Technical Note, Francis Robbins Upton, July 1st, 1880
Editor's Notes
BAst fiber expts, at least some of them on batter current. Resistances; observations of blue coloration (eg "at the top of the lamps a bad spot and blue around it. The lamp when it broke was filled with blue...."). Seems to refer to dynamo as "motor": [fr 163]"wrought iron motor 92 volts running 11 lamps...." Fr 168 looks like wiring scheme for dynamo tests with regulator.
