provinces, we cannot but consider it as singular that so close an 
approximation to equality should exist. 
In the state of Delaware, the first, second, and fourth classes 
of males, and also the first and second classes of females, are 
distinguished by changes of a decreasing kind. Two other 
classes of the females, namely, the third and fourth, received 
only increments of a very feeble kind. The results also of 
the enumeration for the period comprised between 1800 and 
1810, exhibited some singular relations, containing the only 
example of a class of persons, altogether stationary, and also of 
two other classes approximating very closely to the same state. 
In the decade from 1810 to 1820, there are likewise three classes 
of a similar kind. The magnitudes, also, of the increments of 
the last class of each sex, must be considered as very great, 
when contrasted with those which precede them. Causes of a 
very peculiar nature must have operated on the state of Dela- 
ware, to have produced such a series of increments as have here 
been referred to. 
The equality which exists in the first class of the male and 
female increments of Ohio, has been already noticed ; but it is 
also deserving of remark, that the fourth class of males pos- 
sesses an increment precisely similar to the first. In the period 
from 1800 to 1810, the maximum male and female increments 
were found in the final classes ; but in the succeeding census, 
it was only found to hold good in the females, the greatest in- 
crement in the male population being found in the third class. 
This circumstance is most probably to be accounted for, from 
the immense number of young men who have been known to 
emigrate to the state of Ohio, in consequence, probably, of an 
impression which was at one time very strong in the public mind, 
that it possessed advantages superior to any other American 
state, and hence was resorted to by multitudes of the young me- 
chanics of England. 
In Indiana, notwithstanding the increments are so very great, 
a considerable degree of uniformity prevails among them, the 
average of the male rates being 513, and of the females 514.4, 
— a remarkable approach to equality, when the irregular nature 
of the operating causes is considered. This tendency of nature 
to produce a balance in her aggregate operations, is also cu~
