'5. No register is kept of persons consulting the Library; accordingly, the number of students who have frequented it during the last ten years cannot be ascertained. 'I have, &c. 'BULKELEY BANDINEL, '_Bodleian Librarian_. 'George Cornewall Lewis, Esq., 'Under-Secretary of State, Whitehall.' The estimate of printed volumes here given is believed to be as nearly accurate as it was possible to make it, as considerable pains were taken in forming the calculation. The number of separate printed books and tracts may be reckoned as at least treble the number of volumes. With regard to the reply to the fifth enquiry some explanation is requisite. A register is kept of all the octavo and most of the quarto volumes taken out for readers, of all the volumes from special and separate collections, and of all the MSS.; but no account is kept of the folios and other books on the ground-floor of the great room, which are accessible to readers themselves, and frequently used by them without the help of the assistants. Consequently, any return of the number of readers entered on the register would not adequately represent the whole number of students who use the Library, although, of course, it would, with a margin for allowance, afford a very fair approximation. No record, however, of separate _visits_ of readers is kept, as distinct from the books required; so that although a reader may be at work for days or weeks together, yet, if he continue to use only the same books, one entry alone will be made of his name. [346] A separate list of the books purchased at Jacobs' sale is appended to the annual Catalogue. A.D. 1850.
