Copy letter from Robert William Frederick Harrison, to Dr Augustus Desire Waller, Fellow of the Royal Society A new certificate with be necessary for Dr Plimmer, as his certificate cannot be re-suspended, as he was not a candidate last year. Harrison presumes the misunderstanding occurred when Waller did not follow through the new rule that certificates and requests for re-suspension must be sent in by the end of the year preceding that election. The six signatories for Plimmer are accessible, and still in London. 17 October 1904
