Vaillant, the bookseller, who had an unlimited commission from the Earl of Sunderland.' Among the items was an edition of Virgil, printed by Zarothus _circa_ 1475: 'It was noted that when Mr. Vaillant had bought the printed Virgil at L46, he huzza'd out aloud, and threw up his hat, for joy that he had bought it so cheap.' When this famous book-collector died, Wanley observes that 'by reason of his decease some benefit may accrue to this library [Lord Oxford's], even in case his relations will part with none of his books. I mean, _by his raising the price of books no higher now_; so that, in probability, this commodity may fall in the market; and any gentleman be permitted to buy an uncommon old book for less than forty or fifty pounds.' The third son of this famous book-collector, Charles, fifth Earl of Sunderland, and second Duke of Marlborough, greatly enlarged the collection formed by his father; and it was removed to Blenheim probably in 1734. This famous library remained practically intact until it came under the hammer at Puttick and Simpson's, occupying fifty-one days in the dispersal at intervals from December 1, 1881, to March 22, 1883, the total being L55,581 6s. It is stated that the library originally cost about L30,000. Dr. David Williams, who from 1688 to the end of his life was minister of a Presbyterian congregation which met at Hand Alley, Bishopsgate Street, was a contemporary book-collector and book-hunter. His special line was theology, and his library, which absorbed that of Dr. Bates, once Rector of St. Dunstan's-in-the-East, is still preserved intact, and is now, to a certain degree, a free library. Archbishop Tenison was another great book-hunter of this period, and his library was preserved more or less intact until 1861, when it was dispersed at Sotheby's, under an order of the Charity Commissioners.
