DURATION or HUMAN LIFE. 6r 
fa y as Out of 193 deaths, in the congregations of Chrift-church and St. Peter’s, from Chrift- 
mas 1781 to Chriltmas 1782,---24 died of the fmall pox, 21 of purging and vomiting, and 27 
of fits andconvulfions. ‘The average. number of deaths, in the fame congregations---during 
the ‘years 1788, 1759 and 1790---is only 145; and not quite 145. 7-8, during the, 22 years, 
from which the table for Philadelphia N°. 1 is formed--'The deaths, therefore, in 1782, exceed- 
ed the average number of thofe for the 22 years, in the proportion of £36 to 109: and, con- 
fequently, the year 1782 was unufally fickly in Philadelphia, as wellas at Salem in Maflachu- 
fetts. Inthe year 1789, alfo (viz. from Chriftmas 1788 torChriftmas 1789,) out of 164 per- 
fons, who died in the congregations of Chrift-church and St. Peter’s, 29 died of the meailes. 
From thefe circumitances, it is reafonable to fuppofe---that even the /econdtable for Philadelphia 
gives the probabilities of life too low, for this city; becaufe, out of the four years above menti- 
ened, one was more fickly than common; and, during another, near one eighth of the deaths 
from which that table is formed, were occafioned by a diforder not annually epidemic.----In 
the year 1782, there died between the age of 80 and go years, out of 198,---3 perfons; in 1788, 
outot 126,---1; in 1789, out of 164,----3; and in £790, outof 145,---5; being, in the whole, 
12 out of 633: and this gives the proportion of 6 perfons, out of 1000, attaining to go years of 
age. 
(6) The meafles having been very mortal at Salem, in 1783,---that year has been omit- 
ted, in calculating the proportion of deaths, for the firft twenty years of the ages. AOR 
(¢) ‘The number of deaths at Salem, exclufive of the fill-born, during the years 1782, 
1783, 178y---av-raged 1674 per annum; and the number of thofe who died between Soand 
go years of age, during the fame term, averaged 4 per annum---This gives the proportion of 
thofe dying, between the 80th and goth year of life, in that town, as 23. 88 out ef 1000 deaths. 
‘The biils for 1782 and 1783 do not notice any deaths, afler 90 years of age, and this is alfo the 
cafe; with the bill for 1789 : but, in the two former, the lifts of ages comprehend 36 deaths 
of “ages unknown,” and, inthe year 1790, three furvived go'years of age. See the tabis 
for Salem, for the year 1790. 
(¢) Out of 191 deaths, from which this table is found, two were between the age of go 
and 109 years, and I at 103 years. . 3 
fe) According to M. Buffon, the proportion of deaths, at Paris, in the two firt years of 
life, is 313, 21 out of 10003 and, at London, 334..59, out of tooo. The number of deaths, “he 
obferves, is greater at Paris than.in London, from two years of age to five; lefs at Paris than 
at London, between § and 50 years ;- pretty nearly equal, in both cities, between 50 and 60; 
and much greater at Paris than at Londen, from the both year of age to the end of life --'This 
fhews, continues M. Buffon, that o/d age is, in general, much lefsin London than in Paris? 
for, out of 1000 perfons,) 222 died after compleating their Goth year, at Paris ; whereas, only 
138, out of rooo, died after that age, at London.--The continual fupply of peopie, moftly from 
about twenty years of age and: upwards, which great cities draw from the country, gives the 
proportion of thofe who die at o// age, in fuch cities, much higher than the number of thofe 
born in them would give. Hence the favorable appearance, with relpect to longevity, which 
many great cities exhibit, is cxtremely fallacious: and this obfervation is particularly applica- 
ble to London, where the continual diminution of the number of its inhabitants, occafioned by 
the great excels of deaths beyond the births, renders fuch fupplies neceflary, to fupport its po- 
pulation. $ eae sre ae

(g)- This town contains, according to M. de Buffon, 2337 inhabitants. | _ 
(b) From the rit of July, 1790, to the rft of fuly, 1791, the number of deaths at Sayan- 
na, was inthe proportion of one out of every 31 7-10 of the total number of white inhabitants 
(exclufive of Mariners and Sojourners) in that city. It appears by the cenfus, that, in Janu- 
ary 1797, Savanna contained 1712 white inhabitants--- j ; 
(i) Berlin contains, according to Dr. Price, 134,000 inhabitants, if 
(j) Dr, Price fuppofes the p-oportion of annual deaths to the whole number of the living in 
Edinburgh, to be nearly the jame as in London---I have therefore given the proportion of ons 
to twenty-fix, for both cities; and my reafons for affuming ‘bis proportion---which differs 
confiderably from that ftatec by Dr. Price---willappear, in the courfe of the foregoing obfer- 
tions.--- 
v2 (4) By the London Bill of Mortality, made up from the 16th of Dee. 1788, to the 1sth 
Dec. 1789, it appears---that, in the 123 parifhes in London and Weitmintter, and the 23 
Out-parifbes in Middlefex and Surry, 20,749 perfons were buried within the year. Of this 
number, thofe who died after compleating the feveral periods of age, after mentioned, give 
the following proportions, viz. \ ;
