Harris's plan of London, Westminster and the borough of Southwark with all the additional streets, squares &c.; also the improved roads, to the year 1794
Publisher: Harris, John
This map is the seventh edition of an original plan of 1779. Differences between the fifth and sixth edition five suggest that the plate was re-engraved, at least in parts, as additional buildings appear in the sixth edition, dating from 1791. This edition claims to show London as it was in 1794, although no discernible features distinguish it from the previous edition.
An alphanumeric table of references and a grid of half-mile squares aids orientation. A small diagram in the bottom right corner instructs the user on how to use the grid. The bottom margin has been trimmed away, removing the print seller's imprint.
