  <dc:title>Copy letter from Robert William Frederick Harrison to Dr Edridge Green</dc:title>
  <dc:description>'Dear Dr Edridge Green, 
Your offer to exhibit a spectroscope for testing hue perception has been brought before the Exhibits Committee, and I am directed to say that they regret they are unable to include the exhibit in the programme, owing to lack of space.'</dc:description>
