‘The expeBation of the former, it has been (hewn,, 
cannot exceed 20 years, and 30 years have been al-_ 
lowed to the latter. One with another, then, they 
will h-^' 7 Q expe^ation of 2 2.1 years. That is, one- 
of 224- every year. ^And, confequently, 
* The whole number of inhabitants in Rome, in the year 
1761, was 157,452; of whom 90,239 were males, and 67,213 
females. And the annual medium of births, for 3 years from 
1759 to 1761, was 5,167, and of burials 7,153. According to 
this account, therefore, a 22d part of the inhabitants die in 
Rome every year. See Dr. Short’s Comparative Hiflary of the 
increafe and decreafe of mankind in England and fever al countries 
abroad^ p. 59, 60. -In Berlin, as the fame author relates, 
p. 69, in fix years, from 1734 to 174O, the annual medium of 
births was 3,504, of burials 3,639, and the number of inha-- 
hitants was 68,t97; males 32,990, and females 35,207. A 
19th part, therefore, of the inhabitants of Berlin are buried every 
year. As numbers taken by a£lual furvey are generally too 
little, fuppofe, in the prefent inftance, an error committed in 
reckoning the number of inhabitants, equal to a loth of the 
whole number; or to the whole number of children under 5 ; 
and fuppofe likevvife no omiffions in the burialsi The confe- 
quence will be; that about i in 21 are buried at Berlin every 
year. At Dublin, in the year 1695, the number of inhabit- 
ants was found, by an exadl furvey, to be 40,508 (fee Philof. 
Tranfa<Sl:ions, N° 261). I find no account of the annual 
burials juft at that time; but from 1661 to 1681, the medium 
had been 1613; and from 1715 to 1728 it was 2123. There 
can, therefore, be no material error in fuppofing that in 1695 it 
was 1800; and this makes i in 22 to die annually.' In 1745 
the number oi families in the fame city appeared, by an exa<^ 
account laid before the Lord Mayor, to be ^,214. It is pro- 
bable, this number of families did not confift of more than 
50,000 individuals. Suppofe them, however, 55.OCO ; and, as at 
this time the medium of annual burials appears to have been 2,360; 
I in 23 died annually ; fee Dr. Short’s Comparative Hijlory^ 
p. 15, and New Obfervations, p. 228. 1 know not how 
far thefe fadts may be depended on. If they come at all near the 
truth, they demonftrate that I have been very moderate in making
