Copy letter, from Sir John Herschel to Francis Beaufort, dated at Little Hampton Contemporary copy in sender's hand, signed by sender. In reply to Francis Beaufort [see Francis Beaufort's 1831-8-25], John Frederick William Herschel believes that [Henry] Taylor, the person who had done all the reductions of the observations [Stephen] Groombridge's catalogue, should be asked to write the preface, both by reason of his familiarity with the material, as well as having earned the right to do so. 29 August 1831
