Detail from OSD 152 (Hampstead)
1 : 31680
The individual settlements that make up this area of London are shown by red blocks, with boundary lines indicating the fields separating them. Shading and soft interlining indicate relief, neatly illustrated at Primrose Hill, the summit of which is left bare. The barracks at the edge of Hyde Park are illustrated at the very bottom of the map. The dark blue-black line running from West Drayton to Brentford and Paddington is the Grand Junction Canal. This was London's principal link to the rest of Britain's canals, allowing the passage of goods to and from the industrial towns of the North and Midlands. Hyett includes a ground plan of Kenwood House in Hampstead, showing a level of detail much greater than might be expected from a map with a scale of two inches-to-the-mile.
This map of London was produced for the 1832 Reform Bill that established the metropolitan boroughs. The map's title features along the top; with a compass star at top right, an explanatory note at bottom right. At bottom left is a list of the 'liberties' of the city - the name given to areas exempt from the jurisdiction of the country sheriff, being subject to a separate commission of the peace (in this case royal and governmental authorities). The new boroughs are highlighted in colour, with the shaded area representing the old boundaries of London, Westminster and Southwark.

LONDON AND ITS ENVIRONS LEVELS TAKEN BY ORDER OF THE COMMISSIONERS OF SEWERS
The cholera outbreaks of the 1830s and 1840s forced the government to make drastic improvements to the methods of drainage and sewage disposal in London. A Metropolitan Commission of Sewers was charged with the central task of unifying the existing piecemeal drainage system and forming a plan for a completely new one. A new map showing the levels of the land to be drained was needed for this. In March 1848, officers of the Royal Engineers began to prepare stations for triangulation. Observation posts were set up on one of the towers of Westminster Abbey and over the cross of St Paul's. This map is the result of the survey, showing the relative altitude of the land, a necessary preamble to planning drainage systems, as sewage can only be washed away downhill.
JURISDICTION OF THE METROPOLITAN POLICE
This map illustrates plans for the reform of the jurisdiction of Metropolitan Police. Based on Dawson's map of 1832, the map’s title appear along the top, with compass star at top right, explanatory note at bottom left, and a scale bar at bottom right. District boundaries are highlighted in colour, with the old limits of London, Westminster and Southwark shaded. Formed in 1829, the Metropolitan Police had its jurisdiction extended in 1839to Greater London - an area taken to mean all parishes partly within twelve miles of Charing Cross or wholly within fifteen miles of Charing Cross. In the same year, the City of London formed its own police force.

Plan of a Proposed TURNPIKE ROAD From St. JOHN'S CHAPEL, ST. MARYLEBONE into the Great North Road Near the 8 Mile Stone at Finchley
1 : 31680
Plan of the proposed turnpike road from Regent's Park to Finchley, today's Finchley Road. The plan features title at top right, scale bars at lower right and sections of the road in elevation at the foot of the plate, with the new road represented by a double dotted line coloured red. Down the left of the plate a table gives distances between stations along the road and shows the savings in milage generated by the new road.
