of Holland and Weft-Frieftand : Which, I think, 
will be no difficult matter to make appear, by allow- 
ing that Gentleman his fuppos'd Number of 28000 a 
Children to be annually born in the faid Province; 
whereas, according to the above-fpecified ten Years 
Account, and the Faris Proportion of Births, there 
mud be annually born in London thirty-one thoufand 
and eight Children : Therefore, as this Number, ac- 
cording to my Calculation b , is the Produce of 72 5*903 , 
the prefent Number of the Inhabitants of London } 
fo muft 28000 c , the Number of Children fuppofed to 
be born yearly in the Province of Holland and Weft - 
Frieftand y be the Produce of 657485*, the prefent 
Number of the Inhabitants of the faid Province, 
Notwithstanding Mr. KerJfeboom y by his exceffive 
and unprecedented reckoning of the Births at a thirty- 
fifth part of the People, has calculated them at 
• 980000 ; whereas by the ingenious and learned Dr, 
Halle/s Method of Calculation (which is fo highly 
approv'd of by Mr. Kerftfeboom , that he feemingly 
would be thought to make it the Standard of his Cal- 
• culations) the Inhabitants of the Province of Holland 
and Weft-Frieftand do not amount to twenty-nine 
times the Number of the Births s which gives room 
to fufpeft, that Mr. Kerftfeboom has introduc'd this 
unheard-of Excefs, to increafe the Number of People 
in the faid Province of Holland and Weft-Frieftand .
