Lewis's Topographical Dictionary
This is the first edition of this map, drawn by Creighton, engraved by T Starling and published by J&C Walker.
Scale correct at 15 miles = 52.5mm, or 7.25 miles/inch, ie 1:460,000.
The maps appeared in later volumes of the Dictionary in 1833, 35, 38, 40, 42, 45 and 49, often with further information added/removed. Examples are Election and Polling places (1833) and Poor Law Union Boundaries (1841).
