In the division of this Table, which comprises the period from 
1800 to 1810, the male increment attains its maximum, in the 
class of persons under ten years of age ; and its least value in 
the class of twenty-six, and under forty-five. In the same di- 
vision, the maximum of female increment occurs in the class of 
persons of sixteen, and under twenty-six, and accords with the 
greatest male and female increments of the succeeding division. 
In this last division also, the minimum increments occur for 
each sex, in the class of persons under ten years of age. The 
male and female increments of the class of persons under ten 
years of age, in the second division, exhibit a remarkable con- 
trast to the corresponding increments of the third division ; the 
former having a difference of nearly 10 per cent, in the rates of 
their increase, while the latter is nearly in a state of equality. 
The same remark will also apply to the class of forty-five and 
upwards, in the same divisions : for in the second division, the 
male increment of this class has an ascendancy over the female 
increment of the same class of 6 per cent . ; whereas the corres- 
ponding increments of the succeeding division approach nearly 
to a state of equality. The near approximation also of the'
