12. An appendix concerning the different number of sea-fish and wild-fowl at the end of every thousand years since Noah’s Flood. 13. An hypothesis of the use of those spaces (of about 8,000 miles through) within the globe of our earth, supposing a shell of 150 miles thick. 14.

Twelve ways whereby to try any proposal pretended for the public good. 8. How the city of London may be made (morally speaking) invincible. 9. A help to uniformity in religion. 10. That it is possible to increase mankind by generation four times more than at present. 11. The plagues of London is the chief impediment and objection against the growth of the city. 12.

BY the city of London we mean the housing within the walls of the old city, with the liberties thereof, Westminster, the Borough of Southwark, and so much of the built ground in Middlesex and Surrey, whose houses are contiguous unto, or within call of those aforementioned. Or else we mean the housing which stand upon the ninety-seven parishes within the walls of London; upon the sixteen parishes next without them; the six parishes of Westminster, and the fourteen out-parishes in Middlesex and Surrey, contiguous to the former, all which, 133 parishes, are comprehended within the weekly bills of mortality. The growth of this city is measured. (1) By the quantity of ground, or number of acres upon which it stands. (2) By the number of houses, as the same appears by the hearth-books and late maps. (3) By the cubical content of the said housing. (4) By the flooring of the same. (5) By the number of days’ work, or charge of building the said houses. (6) By the value of the said houses, according to their yearly rent, and number of years’ purchase. (7) By the number of inhabitants; according to which latter sense only we make our computations in this essay.
