  <dc:title>Letter, from John Tyndall to Sir John Herschel, dated at Royal Institution</dc:title>
  <dc:description>Autograph letter signed by sender. John Tyndall does not have 'luxury' of using sunshine; uses electric light. Perhaps this adds to inability to obtain heat spots [see John Frederick William Herschel's 1864-11-16].</dc:description>
  <dc:date>17 November 1864</dc:date>
