The earlier Christopher Saxton plate of the county included several neighbouring ones and Philip Lea desired a new plate for his edition of the atlas. He instructed Francis Lamb to engrave a map which remained unsigned, The map draws on Sir Jonas Moore’s great survey on the Fenns published in 16 sheets in 1684. This is a very rare map as it was not acquired by George Willdey at the sale of Anne Lea’s stock in 1730. It was acquired by the Bowles family whose own imprints are even rarer. Willdey had to fill in the gaps in the set of Saxton county plates. The maps were made available individually and Hodson was unable to locate any advert for an atlas. Only four such atlases survive each with varying content. It features inset plans of Cambridge and Ely both with keys and is extensively decorated with 18 coats of arms. Hodson I p. 145.
