  <dc:title>Letter, from Henry Warburton to Sir John Herschel, dated at 45 Cadogan Place</dc:title>
  <dc:description>Autograph letter signed by sender. Glad that John Frederick William Herschel shows renewed interest in mathematics. Besides Henry Warburton, John Frederick William Herschel, Augustus De Morgan, and Mr. Gerard, there appear to be no others interested in researching the differences of the powers of zero. Gave outline of Henry Warburton's paper at Cambridge Philosophical Society. Plans to revise it according to suggestions from John Frederick William Herschel and De Morgan.</dc:description>
