At ROME, an account is taken every year of the num- 
ber of inhabitants ; and, in the year 1 7 7 i , it was 159675. 
The average of deaths for ten years had been 7367 ; 
one, therefore, in 21^ died annually. 
In LONDON I have fliewn, with an evidence which I 
think little fliort of demonftration, that at leall i in 2o|- 
of the inhabitants die annually And, from a parti- 
cular furvey and a very accurate regilfer of mortality at 
NORTHAMPTON, it appears^ that i in 267 die there an- 
nually. 
Let thefe fa6ls be compared with the following. In 
1767, a furvey was made of the inhabitants of the illand 
of MADEIRA, under the diredtion of Dr. thomas heber- 
DEN, and their number was found to be 64614. The 
average of burials for eight pi'eceding years had been 
1293. Only I in 50, therefore, of the inhabitants died 
annually (fee Philofophical Tranfadtions, vol. LVII. p. 
461.). 
to the prefent time; but the vefult of it, for the nine years I have mentioned, as 
given by M. wargentin in this Memoir,, contains indeed a moil curious ac- 
count of the Rate of population in Sweden; and it is particularly to my prefent 
purpoft to mention, that it Brews, that though a igth part of the inhabitants of 
Stockholm die every year, yet in the whole kingdom, taking all the towns and 
country together, not more than a 35th part die every year. In 1757, Sweden 
conlifted of 1101595 males and 1221600 females; in 1760, of 1121053 
males and 1246445 females; and in 1763, of 1165489 males and 1280905 
females. The annual average of births, from 1755 to 1763, was 46223 males 
and 44017 females; of marriages, 21219; of deaths, 34088 males and 35037 
females.
