  <dc:title>Copy letter, from Sir John Herschel to John Tyndall, dated at Collingwood</dc:title>
  <dc:description>Copy of a letter. Thanks for paper verifying John Frederick William Herschel's prediction that explanation of blue sky color carries with it that of polarization of skylight. Involves ultimate link between chemical and analytical dynamics. Notes that 'neutral points' in sky polarization have yet to be explained; offers tentative explanation based on clues in John Tyndall's work.</dc:description>
