Copy letter from Herbert Rix, to Dr Arthur Sheridan Lea, [Fellow of the Royal Society] 'Dear Sir, I cannot understand the usual circular not having reached you with the abstract of Prof J R Green's paper. It was certainly written & we seem to remember enclosing it. However, the paper is referred for an opinion as to its suitability for the Philosophical Transactions ['Philosophical Transactions of the Royal Society'], and I inclose herewith the stamps for its return. Yours truly Herbert Rix Asst Sec RS [Assistant Secretary, Royal Society]'. 2 February 1894
