The plan was published in George Staunton’s ‘An Authentic Account of an Embassy from the King of Great Britain to the Emperor of China’, a work which recorded Britain’s first official embassy to China, headed by Lord Macartney, in 1792. The plan is upon a scale of 1000 yards to 3.5 inches, and not only shows the city in great detail but also gives information on soundings and seabed notation. Beneath the title is a 37-point key listing forts, parishes, colleges, convents, chapels, and other buildings and places ‘most remarkable’. Among the more remarkable buildings are Sang-miau a Chinese Temple, the English Factory, and the Island of Isla Verde.
