the results will be found of a very dissimilar kind. The large 
increment of Alabama, is succeeded by one of a comparatively 
small magnitude in both sexes ; whereas in Missisippi, the con- 
trary takes place, the lesser rate of increase being followed by 
the greater ; and it would seem as if the greatest and least rates 
of increase had mutually interchanged places with each other. 
How uncertain must have been the causes which contributed to 
produce conclusions so much opposed to each other as these ! 
In Illinois, considering the great magnitude of all the incre- 
ments, a greater degree of uniformity will be observed to pre- 
vail among them, than in either of the territories last reviewed. 
The transitions from one rate of increase to another, are not of 
so abrupt a kind as in those prevailing in the state of Alabama. 
In Michigan, the greatest male increment will be found in the 
third class, produced probably by the causes operating on Ala- 
bama. If we contrast the increments of the sexes of this state, 
as in the next Table,

their great irregularities will be immediately apparent. If the 
results of the first column, for example, be compared with each 
other, no one could anticipate such conclusions as the third and 
fourth columns present, at least not from the ordinary laws of 
human procreation *.
