Abstract :
Authors´ closing discussion of a paper published in the December 1934 issue, pages 1581–9, and presented for oral discussion at the cables session of the winter convention New York, N. Y., January 24, 1935. Other discussion of this paper was published in the March 1935 issue, pages 324–6, and in the April 1935 issue, pages 436–7. E. H. Salter, G. B. Shanklin, and R. J. Wiseman: In reference to the comments by R. W. Atkinson in regard to the difference found when the phase rotation of current was reversed, analysis of these data did not give a logical reason why a difference should be found. We could not explain it on the basis of accuracy of test methods because the difference is in the same order of magnitude as was found for other factors which we knew did influence a-c losses. It was decided to include the data in the paper with the hope that someone could offer a reason for that which we found.
