TWO ESSAYS IN POLITICAL ARITHMETIC,
Concerning the People, Housing, Hospitals, &c., of London and Paris.
TO THE KING’S MOST EXCELLENT MAJESTY.
I do presume, in a very small paper, to show your Majesty that your City of London seems more considerable than the two best cities of the French monarchy, and for aught I can find, greater than any other of the universe, which because I can say without flattery, and by such demonstration as your Majesty can examine, I humbly pray your Majesty to accept from
Your Majesty’s
Most humble, loyal, and obedient subject,
William Petty.
AN ESSAY IN POLITICAL ARITHMETIC
Tending to prove that London hath more people and housing than the cities of Paris and Rouen put together, and is also more considerable in several other respects.
1. The medium of the burials at London in the three last years—viz., 1683, 1684, and 1685, wherein there was no extraordinary sickness, and wherein the christenings do correspond in their ordinary proportions with the burials and christenings of each year one with another, was 22,337, and the like medium of burials for the three last Paris bills we could procure—viz., for the years 1682, 1683, and 1684 (whereof the last as appears by the christenings to have been very sickly), is 19,887.
2. The city of Bristol in England appears to be by good estimate of its trade and customs as great as Rouen in France, and the city of Dublin in Ireland appears to have more chimneys than Bristol, and consequently more people, and the burials in Dublin were, A.D. 1682 (being a sickly year) but 2,263.
