Copy letter from Robert William Frederick Harrison to J E Littlewood 'Dear Mr Littlewood, As the main results of your paper on Bessel Functions have been unfortunately frustrated in a recent paper by Debyo in the Ann der Physik, it did not appear to the Council that it would serve a useful purpose to print it. Prof Lamb assented to that view, so the MS [manuscript] will be returned to you by him as withdrawn, unless you desire that it should remain in the Archives.' 8 July 1910
