which the births bear to the number of inhabitants 
who attain the age of 80, is as 30 to 1. Difeafes 
are moil frequent and fatal here, in the months of 
January, February, and March: and lead fo, in 
July, Auguft, and September. The mortality, of 
thefe two feafons, is as 1 1 to 8 ; and, of the firft 
fix months of the year compared with the lail fix 
months, as 7 to 6. 
In April, 1773, feveral Gentlemen, from mo- 
tives of curiofity, undertook an enumeration of the 
people of bolton y a manufacturing town about 
twelve miles diilant from Manchefter. The houfes 
were found to be 946; the males 2159 ; the fe- 
males 2392 ; and perfons aged feventy years 
and upwards 74. To thefe numbers 17- muft be 
added,, which, by a miftake, were notclalfed under 
either denomination. The inhabitants of Bolton 
therefore amount to 4568 ; the number of indi- 
viduals to a houfe is 4 .8 ; and about a fixtieth 
part of the people have attained the age of feventy. 
little bolton, a fuburb of Bolton, including 
the manor, and extending into the country as far 
as the inhabitants are fubjeCl to fuit and fervice, 
contains 232 houfes; 771 individuals; 361 males;: 
410 females ; and 15 perfons aged feventy years- 
and upwards. From this account it appears that 
the inhabitants are 3 .3 to a houfe ; and that 1 in 
51 has reached the age of feventy. The difference, 
in thefe proportions, between a fmall town, and a 
country manor contiguous to it, is worthy of ob- 
fervation.
