  <dc:title>Copy of letter, from Sir John Herschel to Joseph A. F. Plateau</dc:title>
  <dc:description>Copy of letter, copied as part of the correspondence project led by Colonel John Herschel FRS following the death of his father. Apologizes for not having answered earlier. John Frederick William Herschel's health has been 'indifferent.' Received 'Sur un Problème curieux de Magnetisme' yesterday. Discusses 'alleged free suspension of Mahomet's coffin.' Agrees with Joseph Plateau that 'establishment of a stable equilibrium under the influence of mere magnetic forces is impossible.' Elaborates on an experiment relating to the 'problem.' Lists the works by Joseph Plateau that he has.</dc:description>
