An UNRECORDED STATE. A fine large scale plan of London extending to Newington, East India Docks, Camberwell and Paddington. Robert Holmes Laurie succeeded to the business of Laurie and Whittle upon his father’s death in 1812. In 1818 Whittle died leaving him in sole control. The title refers to the degree of accuracy used in producing this plan. It is drawn from the trigonometrical surveys of General Roy using 52 stations at elevated positions from which 450 steeples etc. were determined by over 5000 measured angles. The first state according to Darlington and Howgego is c.1820. A second state is recorded dated 1821. The third he cites is dated ‘Improved Edition 1823-4’ in the imprint below with a similar date in the title. Here ours is dated 1823 as it is in the title. Clearly an intermediate state 2a not recorded. Provenance: owners label pasted to slipcase ‘Charles Lavender’; private English collection. Darlington & Howgego (1964) 283 2a.
