2o (303 x 190 mm). Paginated: [1585]-1594. Disbound. James Watt (1736-1819) first obtained a patent for his steam or "fire" engine in 1769. By 1775, the improvements he had made to the design necessitated this second patent, which gave Watt and his partner, Matthew Boulton, a monopoly on the manufacture of the machine until 1800.
