Copy letter from Herbert Rix, to Professor W G [William Grylls] Adams, Fellow of the Royal Society 'Dear Prof Adams, Did you have a copy of the referee's criticisms on your paper, or was the original report lent to you? I ask because I cannot find the original report, & it is wanted. If you had a copy did you receive it from this office, or from Lord Rayleigh? Yours truly Herbert Rix Asst Sec RS [Assistant Secretary, Royal Society]'. 23 November 1891
