of age, is inconfiderable } and that above that age, 
the numbers of burials may be confidcred, as ariling 
from the natural degrees of mortality ; and then by 
proportion, increaling the numbers of- the living cor- 
refponding to all ages below 25 ; , fo that the table, 
altered in this manner, is the fame with Mr. Smart’s 
above that age. And it mufl: be confelTed, that this 
corredion is very proper, and worthy of its au- 
thor. But ftill the table is greatly defective, as he 
has made no allowance for the recefs of great num- 
bers, who after they have been a number of years 
in town, leave it, if they fiirvive; and of many 
others who, after the age of yo, retire from bufinefs 
into the country. And which is fo very obvious, 
that our burials are fewer, than by proportion they 
ought to be after yo years of age, as I have men- 
tioned above, and by confequence the people ap- 
pear more healthy after that age ; fo that after 70 
they feem more healthy than at Breflau. For at 75 
there appears from this table to die 4 out of 4y, 
whereas at Breflau there die 10 out of 88. 
And that a great number retire from the town, after 
the age of yo, or before, is farther evident j if we 
fuppofe, even according to this correfled table, that 
one in 2y die at the age of jo. For then the num- 
ber of people alive, between 40 and 50, will be 
greater than 2604 multiplied by 25, or 65 lOO; which 
ought to be exhaufled by all the deaths in the fubfe- 
quent periods. But all the deaths which ought to 
arife from that number of living, in the following 
years to 90, according to the bills in the ;^d column, 
is y3iy multiplied by 10, or y^iyo; which is lefs 
than the people that were alive between 40 and yo, 
by
