34 OBSERVATIONS on THE 
ty-fix and an half inhabitants.---Dr. Price prefumes, that 
591,580, is nearly the true number of inhabitants, in 
London; but, that 651,580, though fhort of the number 
fappofed in that city, is very probably greater, and can- 
not be lefs, than the true number.—In the firft cafe, the 
number of inhabitants in London, divided by the annual 
number of deaths (including therein an addition of 6,000, 
for omiffions,) gives 21,°°,,asthe proportion out of which 
one dies annually:—and, in the fecond cafe, that pro- 
portion will be one out of 23 ,4°.. There are, notwithftand- 
ing, fome circumftances, which difpofe me to conclude, 
that London contains 711,516 fouls---Firft ; we find, by 
taking the medium of two eftimates (one by Mefirs. du 
Sejour, Condorcet and dela Place, and the other by M. 
Buffon,) that Paris contains about 626,285 fouls, and 
that there are nearly thirty-two and an half living in that 
city, to each annual death.— We alfo find, that the mor- 
tality of London exceeds that of Paris, about one fourth: 
part,—as eftimated from the births and deaths for each ci- 
ty, refpeQtively: confequently, the number of perfons liv- 
ing, to each annual death, in London, will be twenty- 
fix; agreeably to my hypothefis---Secondly; although 
Graunt, Petty, Morris, Smart, and other Englith authors,. 
have adopted the number of thirty of the living, to each. 
death, for London; yet the Count de Buffon fuppofes--- 
that thirty-one to one, is near the truth: and Dr. Price 
ftates the proportion to be twenty-one to one :---The me- 
dium, therefore, of M. Buffon’s and Dr. Price’s eftimates 
is twenty-fix to one. Now, if we aflume the proportion of 
one birth to twenty-fix inhabitants, annually, for France, 
which is lefs favorable, with refpectto theratio of births to 
inhabitants in that kingdom, than the eftimate of M. du 
Sejour, &c.---and, if it be aflumed as a fad, that one in 
twenty-fix dies, annually, in London; the proportions of 
the births in a year, for the feveral places herein mention- 
. ed,
