Object history
This manuscript was sold at Sotheby's in June 1893 (Phillips sale) and acquired by the Royal Society from a purchaser of that lot. Some of the material is signed by Robin Bacon, who was also Robert Boyle's scribe (see William Poole, 'Sir Robert Southwell's Dialogue on Thomas Burnet's Theory of the Earth: "C & S Discourse of Mr Burnett's Theory of the Earth" (1684): Contexts and an Edition', The Seventeenth Century, 23 (2008), 72-104).
