  <dc:title>Letter, from Humphrey Lloyd to Sir John Herschel, dated at Kilcroney, Bray</dc:title>
  <dc:description>Autograph letter signed by sender. Comments that A. J. Fresnel's papers in the Annales de chimie are really incomplete sketches of theories, which he developed later. Theory clearly stated in [Felix] Billet's Traite d'optique physique. Friend of his at Trinity College has produced a peculiar liquid.</dc:description>
