  <dc:title>Letter, from James Nasmyth to Sir John Herschel, dated at Penshurst</dc:title>
  <dc:description>Autograph letter signed by sender. Regrets that John Frederick William Herschel's engagements prevent them visiting Penshurst. J. Nasmyth too is unable to manage the dates quoted. Hopes his own Herschelian helioscope will be in action by the time the Herschels visit Penshurst.</dc:description>
