List of the Principal Streets, Squares, Public Buildings, etc,

with Reference to the accompanying Plans.

The large Map of London, on the scale of 1: 21,200, is divided into three sections, of which the uppermost is distinguished by a red, the central by a white (or colourless), and the lowest by a blue border. Each section contains 72 numbered squares. In the accompanying index the capital letters R, W, B, following the name of a street or building, refer to the different sections, while the numbers correspond with those on the squares in each section. When the name required is also to be found on one of the special plans, this is indicated by an italicised Roman numeral. Thus, Adam Street, Adelphi, will be found on the section bordered with white, square 30; and also on the second special map.

The numbering of the squares is so arranged, that squares in different sections bearing the same number adjoin each other. Thus, square 16 on the red section finds its continuation towards the S. in square 16 on the white section.

The squares will also be useful for calculating distances, each side of a square being exactly half a mile, while the diagonals if drawn would be 1,244 yards.

Names, to which Great, Little, Old, New, Upper, Lower, or Saint are prefixed, are to be sought for under these prefixes.
