  <dc:title>Letter, from Sir William Pole to Sir John Herschel, dated at 3 Bird Cage Walk</dc:title>
  <dc:description>Autograph letter signed by sender. Explains why his paper on color vision took the artist, dyer, etc., point of view rather than that of scientific chromatology. Willing to investigate a more scientific approach and asks permission for another visit.</dc:description>
