336 Of the Checks to Population, S$c. Bk. ii. 



riages as 4 to 1 ; of births to the population as 1 to 

 23.2 ; of deaths to the population, of males, as 

 1 to 33 ; of females, as 1 to 36 ; of both together, 

 as 1 to 34| ; and of marriages to the population as 

 1 to 94. The proportion of the excess of the 

 births above the deaths to the population is as 1 

 to 62 ; an excess which, if continued, would double 

 the population in about 43 years. As it is not 

 however stated how long these proportions have 

 continued, no very certain conclusions can be 

 drawn from them ; but there is little doubt that the 

 population is proceeding with great rapidity.
