54 Mr Harvey on the Increase of' the Population of the 
close approach to equality, between the male and female incre- 
ments, in four classes out of five, into which the ages are divid- 
ed. The single class, indeed, where this degree of equality does 
not exist, namely, in that of twenty-six and under forty-five, the 
difference is not very considerable. The causes, therefore, that 
have operated in Kentucky to increase its population, have acted 
almost uniformly on all ages. In Delaware, the rates of increase 
are very singular. Both the male and female classes under ten, 
and also the fourth and fifth classes of each sex, present exam- 
ples of moderate increments ; but the third class of females we 
find stationary, the corresponding class of males with only an in- 
crement of /jjthsy^r cent . ; and in the second class of males and 
females, increments almost equally feeble. The first class of 
males in Connecticut, and the last class of females in Virginia, 
present the only instances of decrements. 
The maximum increments of the different ages for both sexes, 
appear to exist in some of the States, in the class of persons of 
sixteen and under twenty-six ; and in other States, in the class 
of forty-five and upwards ; the females in Virginia, Tennessee 
and Kentucky, being the only exceptions in this curious law. 
In the following columns, the States and Territories are arran- 
ged, according to the ages in which the maximum increments are 
found.

Although the maximum increments which both sexes have

degree of uniformity, and appear to be the result of some
