491,430.

And the medium of the said two Paris accounts is 488,055.

The medium of the London burials is really 23,212, which, multiplied
by thirty (as hath been done for Paris), the number of the people
there will be 696,360.

The number of houses at London appears by the register to be
105,315, whereunto adding one-tenth part of the same, or 10,315, as
the least number of double families that can be supposed in London,
the total of families will be 115,840, and allowing six heads for
each family, as was done for Paris, the total of the people at
London will be 695,076.

The medium of the two last London accounts is 695,718.

So, as the people of Paris, according to the above account, is
488,055.
Of Rouen, according to Monsieur Auzout's utmost demands 80,000.
Of Rome, according to his own report thereof in a former letter
125,000.
Total 693,055.

So as there are more people at London than at Paris, Rouen, and Rome
by 2,663.

Memorandum.--That the parishes of Islington, Newington, and Hackney,
for which only there is any colour of non-contiguity, is not one-
fifty-second part of what is contained in the bills of mortality,
