  <dc:title>Copy letter, from Sir John Herschel to William Selwyn, dated at Collingwood</dc:title>
  <dc:description>Copy of a letter. Asks whether William Selwyn has photographs of the sun for 21 and 22 April. Notes how curious sunspot activity has been. Doubts that such is reconcilable with the notion of 'meteoric in-falls.'</dc:description>
