Croker, who continually had recourse to him for information on literary subjects. In 1847 he contributed to the _Archæologia_ "Observations on the Division of Man's Life into Stages," with especial reference to Shakespeare's descriptions of the seven ages of man, and about this time wrote several other papers. In 1850 he edited for the Hakluyt Society "Divers Voyages touching the Discovery of America"; and in 1856, "The Travels of Nicolò Conti in the East," translated from the Italian of Poggio Bracciolini. In 1858 he translated for the same Society the Oriental travels of Lodovico di Varthema, edited, with a preface, by his friend Dr. G. P. Badger. Upon the death of the Rev. Richard Garnett in 1850, Mr. Jones became Assistant-Keeper of Printed Books, and succeeded Mr. Panizzi as Keeper upon the latter's promotion to the Principal Librarianship in March 1856. His period of office as Assistant-Keeper was chiefly distinguished by the erection of the new Reading Room, and the libraries in connection with it. The design of this grand and commodious structure belongs entirely to Sir A. Panizzi; but Mr. Jones saw the original sketch (engraved in the catalogue of the Reading Room reference library) as soon as it was made, and was consulted upon every detail during the progress of the work. One of his first duties as Keeper was to edit, with a valuable preface, the above-mentioned catalogue, which had been entirely prepared by Mr. W. B. Rye, late Keeper of the Printed Books. As Keeper Mr. Jones paid the greatest attention to the organisation of his department, which he maintained in the highest condition of efficiency. The number of titles written annually for the catalogue was unequalled before or since, and the department never had so many assistants of literary distinction. He followed in his predecessor's steps in using every possible endeavour to increase the library, both numerically and by the acquisition of special bibliographical treasures. The annual grant, long diminished from want of room to store accessions, was raised to £10,000 in 1857, and Mr. Jones proceeded to expend it with the assistance of the vast literary knowledge of his colleague Mr. Watts, and valuable aid in the acquisition of German and other old foreign books from Mr. Albert Cohn, of Berlin; in American literature from the enterprising and indefatigable Mr. Henry Stevens; and in ancient service-books from Mr. William Maskell. Among the many important official documents prepared by him may be mentioned a memorandum of objections to the recommendations of the Royal Commissioners; and reports on additions to the staff, on the superannuation of assistants, on Civil Service examinations, and on vellum books.
