obferve, that the difference which this furvey gives be- 
tween the rate of mortality in the town of Manchefter 
and the adjacent country, is confirmed by a variety of 
other accounts. It may be ftated in general, that whereas 
in great towns, the proportion of inhabitants dying an- 
' nually is from i in 19 to i in 22 or 23, and in mode- 
rate towns from i in 24 to i in 28 in country parifiies 
and villages on the contrary, this proportion feldom ex- 
ceeds I in 40 or 50. The proofs of this are numerous 
and unexceptionable ; and I have elfewhere given a par- 
ticular account of them (O. I will here only mention the 
following fa6ls. 
The number of inhabitants at Stockholm in 1763 
was 72979. The average of deaths for the fix preceding 
years had been 3802 (d). One, therefore, in nineteen died 
there annually. 
At 
(b) The n^imber dying annually in towns is feldom fo low as i in 28, ex- 
cept in confequence of a rapid increafe produced by an influx of people, at thofe 
periods of life when the feweft die. This is the cafe at Manchefter. It is alifb 
the cafe at Liverpool and at Berlin; in the former of which towns, i in 27 dies 
annually; and in the latter, i in 26f died from 1755 to 1759. See Obferva-

(d) See a Memoir by M. w argentin, in the 15th volume of the Colhnlon 
Academlquey printed at Paris, 1772. From this memoir I learn, that in 1757, 
and 1760, and 1763, a furvey was made of the inhabitants of Sw'eden, diftin- 
guifhing, particularly, the numbers of both fexes living at every age; and that 
alfo, for nine yeare (or from 1755 to 1763), an exaift regifter was kept of the 
number of births and burials in each year, diftinguifhing the age and fex of 
every one that died. I do not know whether this regulation has been continued
