 true number, which in a calculation pf tliis kind is not great, 

 as the data cannot be perfecSUy accurate. 



The mean annual number of deaths in the preceding places 

 of obfervation is nearly .98, and the births nearly 213; the 



natural increafe therefore is lie. Now, if 2000, the number 

 of inhabitants deduced from the tables, were the real flock, 

 this rate of increafe would be fufficient to double the number 

 in a Httle more than rS years and one tliird. But as the real

ftock of inhabitants to be doubled by this increafe -is 6359, 

 the period of duplication is 38 years and 7 tenths. It hence
