Copy letter from Herbert Rix, to Ferdinand Falk, 34 Old Broad Street, E.C. 'Dear Sir, The copying for Dr Wohlwill has been a most difficult task. The letters are almost undecipherable. I doubt whether we shall be able to finish them. In about a week I shall send you what we have done & let you know the cost. I doubt whether it will be worth Dr Wohlwill's while to have the rest done at the same rate. I am yours faithfully, Herbert Rix Asst Sec RS [Assistant Secretary, Royal Society]'. 24 December 1888
