Copy letter from Robert William Frederick Harrison, to Professor [Micaiah John Muller] Hill, Fellow of the Royal Society, Chairman of the Mathematics Sectional Committee Mr Hardy's report on Professor W H Young's paper on 'Trigonometrical series whose cesaro partial summations oscillate finitely' has just been received. He suggests that the author should be asked to give an explicit statement of the results proved by M M Riesz as these appear to be the nearest to the author's results, and that the analysis on page four could be abbreviated slightly for purpose of printing. Asks the Chairman to give instructions. 30 June 1913
