  <dc:title>Letter, from Joseph Johann Littrow to Sir John Herschel, dated at Vienna</dc:title>
  <dc:description>Autograph letter signed by sender. New Observatory is being planned on the lines of the new one being built at Obo in Finland. Would like an open letter from John Frederick William Herschel on the requirements for an observatory. Is there any news of the clock for [L. A.?] Fallon?</dc:description>
