Copy letter from Herbert Rix, to [John William Strutt] Lord Rayleigh, [Royal Society] 'My Lord, Kindly say whether I may accept enclosed estimate. The plans of arrangement are gone to another. The estimate seems to be less than that of the Cambridge Co. for some similiar plates which were done for a biological paper. Yours truly Herbert Rix Asst Sec RS [Assistant Secretary, Royal Society]'. 6 January 1892
