Sir Hans Sloane (1660-1753) is remembered more for his activities in the spheres of science and medicine than for his original contributions to these fields. His large treatise on the natural history of Jamaica (2 vols., 1707- 1725) and other writings were useful additions to the scientific literature, but they were overshadowed by his activities as President of both the Royal Society (1727-1741) and the Royal College of Physicians (1719-1735) and by his having provided the collections which became the foundation of the British Museum. There is no definitive study on him, but the two recent biographies by De Beer and Brooks provide a good picture of his life and work (1). Sloane carried on a voluminous correspondence, and most of the letters written to him are preserved in the British Museum—largely unpublished (2). Among them are a dozen letters from Richard Bradley (1688?—5 November 1732), which throw somewhat more light on Bradley than on Sloane. They also illustrate the adverse conditions under which men without wealth have sometimes worked when pursuing scientific activities. Bradley was a prolific author of books on agriculture, horticulture, biology, and medicine. As will appear from his letters, he was often the pawn of booksellers, and John Martyn (1699-1768), his malicious rival, commented shortly after his death that ‘The booksellers have lost a good easy pad’ (3). Bradley was at times only a popularizer or a hack, but he also produced writings having scientific merit (4). Furthermore, he was a Fellow of the Royal Society and the first Professor of Botany at the University of Cambridge. His correspondence with Sloane is therefore of interest for adding to our knowledge of both men and the scientific activities of their time.
