Copy letter from Robert William Frederick Harrison, to Professor Alfred George Greenhill, Fellow of the Royal Society, 1 Staple Inn, W.C. Harrison sends their printers' estimate of the cost of making the transfer of equation numbers in Greenhill's paper, with samples of two pages. Professor Joseph Larmor, who has already seen the samples, dislikes their appearance but states that if Greenhill wishes the changes to be made at his own expense, the Committee of Papers are likely to agree. The question will have to wait until the next Council. 30 May 1904
