Large and detailed plan of London.

The map bears grid lines for ease of reference, the major public buildings such as Westminster Abbey, the Houses of Parliament, St Paul's Cathedral, Buckingham House, and the Tower of London are represented as birds-eye views.

The text upon the map gives the extent of London as "7500 Geometric paces, that is above 7 English Miles and a half" from west to east and "2500 paces, or 2 miles and a half" from north to south. There are about 5000 streets. The number of houses is calculated to be 110,000. The population is guessed at "by what is eaten": "There were in one Year, when it was less by two thirds [ie. in the mid seventeenth century], 67500 Beefs, 10 times as many Sheep, Besides Poultry &c. also every Year is brought into the River 400,000 at least Charldon of Coales". Also the number of "Buryings" was said to number 26,000 per year. The amount of ale and beer produced is said to be 20,000 barrels. Bowles acknowledges the source of these numbers as Sir William Petty (1623-1687), who through some crude statistical analysis calculated the population in the mid-seventeenth century. He estimated that there were 115,846 families and 695,076 souls; more than Paris, Rome, Rouen or Amsterdam, which were said to have some 500,000 souls. To the left of the text is a list of watermen and hackney carriage rates.
