  <dc:title>Letter, from John Henry Griesbach to Sir John Herschel, dated at Carlton Villas, Maida Vale</dc:title>
  <dc:description>Autograph letter signed by sender. Did not realize that John Frederick William Herschel would leave town so quickly. Cast a 10 speculum successfully after William Parsons' (3rd Earl of Rosse) plan. Is having difficulty with his grinding and polishing and would welcome John Frederick William Herschel's advice."</dc:description>
