Copy letter from Robert William Frederick Harrison, to Dr John Scott Haldane, Fellow of the Royal Society Regarding Haldane's letter concerning Dr Pembrey's certificate, Harrison finds that this certificate is just on the border line. It is valid until next 1 December, when the five years from the date it bears will elapse. Harrison could state a case to the Council for allowing it to hang for the next election. However, Harrison suggests getting a new certificate, as all but one of the original signatories survive (Sir John Burdon Sanderson). 7 November 1910
