Papers on corona

F. W. Peek, Jr.: It is my opinion that apparent discrepancies in the corona papers presented are not due to error in the different investigations, but rather to the difficulty of comparing different conditions. To illustrate what I mean by one example: An aluminum cable strung at Stanford in a grassy field and another strung at Pit after being dragged over the sharp lava rocks should be expected to give different losses near the critical voltage. It would be difficult to predict the result of the mutilation by the lava beds without direct measurements.
