Title
[N14800A], Technical Note, Francis Jehl, Thomas Alva Edison, October 1880
Editor's Notes
Notes and drawings regarding tests of first 69 lamps of Lot 2. The usual measures: cp, EMF, resis; observations of blue glow at clamps; observation of bad and bright spots on carbons; observations of black on clamps. Nothing exciting.
