Copy letter from Herbert Rix, to Professor Edwin Bailey Elliott, Fellow of the Royal Society 'Dear Sir, Lord Rayleigh desires me to forward to you the inclosed note from himself. May I at the same time ask you whether you consider that the figures might be presented by means of half-page blocks, if I find that is feasible, and if the whole 14 figure are actually necessary? I see that the suggestions of the Referees have not yet been carried out with respect to marking certain points in the figures, and I shall not put them in hand until I hear further about this. I am, yours truly, H Rix Asst. Sec. R.S. [Assistant Secretary, Royal Society]'. 22 December 1893
