First edition. Taylor was a computer for the Nautical Almanac, and produced 'the largest sexagesimal table ever issued' (Sotheran's Price Current of Literature, issue 770 (c. 1922), no. 1259, price 14s). He worked successfully as a freelance computer, gaining over £4000 from his table computations. His Sexagesimal Tables proved to be highly useful to astronomers and surveyors. Maskelyne had spotted Taylor's talent, completed and published his work on logarithms, sines and tangents after his death in 1789.
