  <dc:title>Letter, from Adolph C. Petersen to Sir John Herschel, dated at Altona</dc:title>
  <dc:description>Autograph letter signed by sender. No decision has yet been made about closing or moving the observatory, but thanks John Frederick William Herschel for his letter [see John Frederick William Herschel's 1852-5-19], which may become useful support for retaining the observatory.</dc:description>
