Copy letter from Robert William Frederick Harrison to H [Henry Reginald] A [Arnulph] Mallock, Fellow of the Royal Society 'Suggested Soiree exhibits. Mr Goold & Mr Benham. We wrote to Mr Goold for a more detailed description of his and Mr Benham's suggested exhibits. His reply is enclosed. Perhaps Mr Mallock may now be able to advise in the matter. Mr Goold it should be said, has exhibited many times at these Soirees.' 14 April 1908
