But Table IV, will, at one view, fhew, in the 
mod fatisfadtory manner, the comparative ftate of 
health* between this and fome other towns of dif- 
ferent magnitudes* It is curious to compare, by 
this table, in the early part of life, the probabi- 
lity that the inhabitants in Chefter have, to live 
longer than in Northampton, Norwich, and efpe- 
cially much longer than in London. But when 
they have arrived to 70 years old, the chance of 
living* at all the places, is nearly equal. 
It is a matter of curiofity, to obferve how much 
longer women live than men. This fadt is well 
eftabliffied, by former obfervations on this fubjedf, 
and is confirmed by the following regifler (Table!.). 
During the laft year 1 2 widowers have died, and 
53 widows that is above four times the number. 
Between 80 and 90 years old, 2 men and 18- 
women have died; that is nine times as many*, 
Above 90 years old, 4 have died, and all women,. 
To know at what period of life each difeale 
is moft fatal to mankind, is manifeftly a fort of 
intelligence the moft important, both to the patient 
and the phyfician; and though an enquiry, of this 
nature, may be attended with confiderable difficul- 
ties,, yet the advantage of fuch information is fo 
obvious to all, it fee ms wonderful, that no attempt 
has been made, to execute a plan lb generally be- 
neficial to mankind. 
The Table of difeafes (N°. II.) has been com- 
piled with all poffible accuracy. At the beginning 1
