Copy letter from Herbert Rix, to Professor W N Parker 'Dear Professor Parker, I have been obtaining estimates for the typing of your MS. [manuscript]. There is a good deal of German quotation, consisting of lots of long extracts. This adds considerably to the expense. Dr Foster told me to ask you whether these long extracts might not be omitted & the references only given. Yours truly Herbert Rix Asst Sec RS [Assistant Secretary, Royal Society]'. 21 November 1891
