Having done me the honour of exhibiting to the Society of Antiquaries in March 1824, a rough draft of a Map of Roman Norfolk, with other Plans which related to Norwich, I now beg leave to transmit to the Society through you a more finished Map, accompanied by a descriptive Outline of the Roman Remains in that county: and in so doing I cannot but suggest, that if others, conversant with antiquarian pursuits, would construct similar Maps of other counties of Great Britain, the whole might form the basis of a Map of Roman Britain, which is much wanted. The advantages resulting, would, I am convinced, fully compensate the labour; much light would be thrown upon the works of Gale, Horsley, Reynolds, and other learned Antiquaries, who have written on the Itinerary of Antoninus; and the early history of this country be placed in a much clearer point of view than it has hitherto been. The accurate Surveys which have been taken of every County have removed the obstacles which before impeded such an attempt; and these, combined with the geological researches which have of late years been made, particularly in our maritime counties, afford sure data for such an undertaking.
