  <dc:title>Copy letter, from Sir John Herschel to James Prescott Joule, dated at Collingwood</dc:title>
  <dc:description>Copy of a letter. Thanks for his paper on amalgams. Regarding the amalgam of iron, he pointed it out many years ago in his Bakerian lecture. Would be interesting to experiment further with iron in solution of mercury.</dc:description>
