In this year Sir Kenelm Digby gave a collection of 238 MSS. (including five rolls) all on vellum, uniformly bound, and stamped with his arms, which still form a distinct series. They are, for the most part, of the highest interest and importance, especially with reference to the early history of science in England. Amongst them are works by Roger Bacon, Grosteste, Will. Reade, John Eschyndon or Ashton, Roger of Hereford, Richard Wallingford, Simon Bredon, Thomas of New-market, and many others. They also comprise much relating to the general history of England, and are almost entirely the work of English scribes. Many of them had previously belonged to Thomas Allen, of Gloucester Hall, who himself was a liberal donor to the Library. [_See_ p. 19.] Two additional MSS., which formerly belonged to Digby, and which each contain his inscription, 'Hic est liber publicæ Bibliothecæ academiæ Oxoniensis, K.D.,' were purchased in 1825. One of these, _R. Baconis opuscula_, was bought for £51; the other, a Latin translation, by W. de Morbeck, of Proclus' Commentary on Plato, for £31 10_s._ They are uniformly bound with the rest of the series, and are numbered 235 and 236 respectively. The donor stipulated that his MSS. should not be strictly confined to use within the walls of the Library. Archbishop Laud says, in the letter in which, as Chancellor, he announced the gift to the University, 'hee will not subiect these manuscripts to the strictnes of Sir Thomas Bodley's statutes[92], but will haue libertie given for any man of woorth, that wilbee at the paines and charge to print any of these bookes, to haue them oute of the Librarye vpon good caution giuen; but to that purpose and noe other[93].' But he afterwards left the University at liberty to deal as it pleased with his MSS. in this particular, as well as in all other questions that might arise concerning his books. In a letter to Dr. Langbaine, dated Nov. 7, 1654, he says: 'The absolute disposition of them in all occurrences dependeth wholly and singly of the University; for she knoweth best what will be most for her service and advantage, and she is absolute mistress to dispose of them as she pleaseth[94].' He mentions in the same letter two trunks of Arabic MSS. which he gave to Archbp. Laud to send to the University or to St. John's College, but he never heard whether they reached their destination or no. He promises also to send over some more MSS. from France when he has returned thither; since, when the troubles of the Rebellion drove him into exile, he had carried his library with him. Upon the Restoration, however, and his own return to England, he unfortunately left his books behind; and after his death they were confiscated by the French King as belonging to an alien, and subsequently sold. Doubtless the two MSS. acquired in 1825 were among those to which his letter refers.
