Copy letter from Robert William Frederick Harrison, to Professor Michael Foster, Secretary, Royal Society Dr [Henry Edward] Armstrong has revised the physical index slips for the new number of 'Proceedings [of the Royal Society]', but did not undertake the biological ones, which Harrison is therefore constrained to send to Foster for Heape, Herbert Thompson and Risien Russell. The fourth paper by [John Bretland] Farmer on Fucus, Armstrong has taken to consult the author about. On the enclosed slips White has copied out the titles for the first heading. Harrison encloses a note of other matters in the form of a memorandum which Foster can return with notes upon if desired. [No attachments]. 10 October 1896
