The City of Leyden comes next in Consideration^ 
It appears by a Lift for 50 Years, namely, from the 
Year 1690 to 1739 incluftve, that there have been 
buried in that City annually, on an Average, 1919 
Perfonsj and married during the fame Time, annu- 
ally, on an Average, 558 Couple, which, agreeable 
to the former Rule, would produce 1813 Children per 
Annum , but is found to have been 1834 per Annum y 
on a Medium, as aforefaid; the Author concludes 
confequently, that this City contains 63000 Souls. 
The next City in View is Amfterdayn : It appears 
by a Lift, that ftnee the Year 1696 to 1738 incluftve, 
there have been buried in this City 7323 Perfons 
annually (Jews excepted) ; and there having been 
married, during the fame Time of 43 Years, 2311 
Couple annually, produced, according to the Author's 
Computation, 7134 Children annually, at a Me- 
dium j and takes it thence for certain, that Arnfler- 
dam contains (including 20000 Jews, as obferved in 
his Firft Treatife, Page 21.) 241000 Souls. The 
Author proceeds, in the like curious Manner, about 
other Places ; but left, dwelling too long on this 
Particular, it might prove tedious in this Place, I 
will proceed with obferving, that the Author gives 
next a Table how long 432 Widows lived during 
a Century, and fhews it to have been near 14 Years 
each on a Medium ; and then fubjoins a Lift how 
many Years married People of different Ages con- 
tinue to live probably together, before the Bonds of 
Matrimony, by the Death of cither Party, arc dif- 
folvedj namely, ,
