Abstract :
L. I Komives (The Detroit Edison Company, Detroit, Mich.): This paper, in the opinion of The Detroit Edison Company, is a very valuable and useful addition to the literature on this subject. We believe that the authors have done an excellent job in co-ordinating the data available, and that this paper will be a widely quoted reference. We agree with most of the major conclusions which the authors have drawn and would like to make observations only on some.
