Copy letter from Herbert Rix, to Professor Frank Clowes, University College, Nottingham 'Dear Frank, Your paper has not arrived. What has become of it? The 18th is our last meeting & the papers will be mostly if not all taken as read. It is very unlucky. Still, you had better be present, & perhaps they will give you ten minutes. Yours truly Herbert Rix Asst Sec RS [Assistant Secretary, Royal Society]'. 2 June 1891
