Lot Essay
The Royal Society of London was officially incorporated in 1662, although there had been preliminary meetings in London, which Boyle attended, as early as 1647. In Part I of The Usefulness of Experimental Philosophy, which was drafted in about 1650, Boyle attempted to justify the activities of the virtuoso experimentalists in the eyes of their contemporaries. Part II was written later and published in 1671 (see Fulton p. 37).
