  <dc:title>Letter, from David Brewster to Sir John Herschel, dated at Edinburgh</dc:title>
  <dc:description>Autograph letter signed by sender. It has been a long time since he last heard from him. Very busy with professional pursuits. Congratulations on receiving the Copley medal. Would like an abstract of his article on aberrations in chromatic lenses. Comments on this.</dc:description>
