  <dc:title>Letter, from Basil Hall to Sir John Herschel, dated at HMS Conway, Valparaiso</dc:title>
  <dc:description>Autograph letter signed by sender. Sending some observations on a comet which appeared last month. Has had the pendulum up for some weeks but has been unable to carry out many observations owing to official duties. Has been working a good deal on occultations. Wishes some had been published as they are of great practical use.</dc:description>
