Robert Whipple amassed a large collection of the works of Robert Boyle (1627–1691), including some extremely rare editions. There are around 140 items, covering all aspects of Boyle's published work, including books on theology and natural history as well as his better-known chemical work, The Sceptical Chymist (1661). Whipple took particular care over this important collection, as evidenced by the careful annotations in his copies of the bibliography and handlist of Boyle's works, which include the prices paid by him for the books, written in an alphabetical code.
