  <dc:title>Letter, from Robert Hunt to Sir John Herschel, dated at Falmouth</dc:title>
  <dc:description>Autograph letter signed by sender. Returns with grateful thanks the example of photographs recently sent him. They open up a new field of curious processes. Will not have much time this summer for photographic experiments as he is carrying out a series of investigations into the air of mines. Has been experimenting with the cyanurets.</dc:description>
