  1. This work was completed several years ago in the Nela Wesearch Laboratories. It was well under way before the papers on this and related subjects by Davis, Paris and Tucker and several others came to our notice.
  2. Measured with a millivoltmeter with range of 50 millivolts over a scale of 150 divisions. Resistance 0.935 ohms.
  3. Unfortunately no record was made of this resistance.
