    More Information:

    A lovely copy of one of Roy's most famous works. Elected to the Royal Society in 1767, he carried under its auspices a geodetic survey linking London to the coast of France. From 1763, he strongly advocated the establishment of an official national survey, which came into existence a year after his death and is now the Ordnance Survey.
