  <dc:title>Letter, from Sir William Huggins to Sir John Herschel, dated at Upper Tulse Hill</dc:title>
  <dc:description>Autograph letter signed by sender. Unable to make any observations at the moment as his observatory is being enlarged to receive his new large telescope. Thinks it would be a good idea to carry out observations on Mercury. Is not sorry to be able to rest his eyes from his trying spectrum experiments.</dc:description>
