A good copy. A complementary pair of scarce eighteenth century treatises by two unabashedly eccentric and colourful figures from eighteenth century science. The first work, A Short Comment on Sir I. Newton's Principia, is written by William Emerson, (1701-1782), a talented Darlington mathematician and latterly a central character in Thomas Pynchon's 1997 postmodernist novel Mason and Dixie. Taking an egalitarian approach to the teaching of Newton's Principia, it attempts to elucidate complex and difficult mathematical ideas for a common audience rather than the narrow niche of academics. The Second work is the first and only edition of Bedford's rare and outlandish astronomical treatise written in response to Newton's studies in chronology. With printer's ledgers recording only 500 copies being printed. [ESTC]. There is an interesting inter-textual relationship between the two as Emerson dedicates a whole chapter to a comically scathing critique of Bedford's work. The texts side by side offer an insight into the dissemination of and response to Newtonian ideas in the eighteenth century. ESTC: T77159; ESTC: T109509.…
