I think I could still argue my point about page 34 of the manuscript but this is not really a matter of importance. I am therefore prepared to accept the paper in its amended form. Yours sincerely, W. J. Duncan'. Written at James Watt Laboratories, The University, Glasgow [England]. [Published in Proceedings A, 1953].
