The Third Way.

It was proved by Grant, that one-fifth of the people died of the plague, but A.D. 1665 there died of the plague near 98,000 persons, the quintuple whereof is 490,000 as the number of people in the year 1665, whereunto adding above one-third, as the increase between 1665 and 1686, the total is 653,000, agreeing well enough with the other two computations above mentioned.

Wherefore let the proportion of 1 to 30 continue till a better be put in its place.

Memorandum.  That two or three hundred new houses would make a contiguity of two or three other great parishes, with the 134 already mentioned in the bills of mortality:  and that an oval wall of about twenty miles in compass would enclose the same, and all the shipping at Deptford and Blackwall, and would also fence in 20,000 acres of land, and lay the foundation or designation of several vast advantages to the owners, and inhabitants of that ground, as also to the whole nation and government.

THE FOURTH ESSAY.

Concerning the proportions of People in the eight eminent Cities of Christendom undernamed, viz.:-

1.  We have by the number of burials in healthful years, and by the proportion of the living to those who die yearly, as also by the number of houses and families within the 134 parishes called London, and the estimate of the heads in each, pitched upon the number of people in that city to be at a medium 695,718.

2.  We have, by allowing that at Paris above 80,000 families, viz., 81,280, do live in 23,223 houses, 32 palaces, and 38 colleges, or that there are 81,280 kitchens within less than 24,000 street doors; as also by allowing 30 heads for every one that died necessarily there; we have pitched upon the number of people there at a medium to be 488,055, nor have we restrained them to 300,000, by allowing with Monsieur Auzout 6 heads for each of Moreri’s 50,000 houses or families.

3.  To Amsterdam we allow 187,350 souls, viz., 30 times the number of their burials, which were 6,245 in the year 1685.

4.  To Venice we allow 134,000 souls, as found there in a special account taken by authority, about ten years since, when the city abounded with such as returned from Candia, then surrendered to the Turks.

5.  To Rome we allow 119,000 Christians, and 6,000 Jews, in all 125,000 souls, according to an account sent thither of the same by Monsieur Auzout.

6.  To Dublin we allow (as to Amsterdam) 30 times its burials, the medium whereof for the last two years is 2,303, viz., 69,090 souls.

7.  As to Bristol, we say that if the 6,400 houses of Dublin give 69,090 people, that the 5,307 houses of Bristol must give above 56,000 people.  Moreover, if the 29,325 hearths of Dublin give 69,090 people, the 16,752 hearths of Bristol must give about 40,000; but the medium of 56,000 and 40,000 is 48,000.
