At the end of each of the taller cases, in small compartments with doors, are class catalogues written about 1685. These catalogues have been pasted over original catalogues written about 1640; small portions of the earlier catalogues are yet to be seen in some of the cases. Of the treasures in manuscript and print only a slight account can be given here. One of the most interesting to members of the College is the following note by John Couch Adams:-- "1841 July 3. Formed a design, in the beginning of this week, of investigating, as soon as possible after taking my degree, the irregularities in the motion of Uranus, wh. are yet unaccounted for; in order to find whether they may be attributed to the action of an undiscovered planet beyond it; and if possible thence to determine the elements of its orbit, &c. approximately, wh. wd. probably lead to its discovery." The original memorandum is bound up in a volume containing the mathematical calculations by which Adams carried out his design and discovered the planet Neptune. Lord Keeper Williams, who was instrumental in building the Library, presented to it many books; amongst others, the Bible known as Cromwell's Bible. Thomas Cromwell employed Miles Coverdale to revise existing translations, and this Bible was printed partly in Paris and partly in London, "and finished in Aprill, A.D. 1539." Two copies were printed on vellum--one for King Henry VIII., the other for Thomas, Lord Cromwell, his Vicar-General. This College copy is believed to be that presented to Cromwell, and is now unique, the other copy having disappeared from the Royal Library; the volume is beautifully illustrated, and has been described as "the finest book in vellum that exists."
