The Royal Society in the eighteenth century cuts a poor figure in comparison with its robust parent of the seventeenth century. Contemporary satirists and modern historians alike have found little to recommend the weak and well-padded institution. After Newton's death in 1727, it was no longer the centre for natural philosophy, and even during his tenure as President the Society did not escape censure. Fascination with monstrous curiosities and antiquarian puzzles replaced serious scientific work, according to various detractors. Recently scholars have begun to re-evaluate this caricature and point to the myriad ways in which the Society cultivated natural philosophy and natural history during the eighteenth century. This essay focuses on one of the Society's frequently overlooked strengths: its extensive correspondence.
