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.

8. As for Rouen, we have no help, but Monsieur Auzout's fancy of
80,000 souls to be in that city, and the conjecture of knowing men
that Rouen is between the one-seventh and one-eighth part of Paris,
and also that it is by a third bigger than Bristol; by all which, we
estimate, till farther light, that Rouen hath at most but 66,000
people in it.

Now it may be wondered why we mentioned Rouen at all, having had so
little knowledge of it; whereunto we answer, that we did not think
it just to compare London with Paris, as to shipping and foreign
trade, without adding Rouen thereunto, Rouen being to Paris as that
part of London which is below the bridge, is to what is above it.

All which we heartily submit to the correction of the curious and
candid, in the meantime observing according to the gross numbers
under-mentioned.


London 696,000
Paris 488,000
Amsterdam 187,000
Venice 134,000
Rome 125,000
Dublin 69,000
