et the first compartment remain as it stands.
Let East Prussia, which contains a much larger population than his last
compartment, stand alone in the second division. Let the third
consist of the New Mark, the Mark of Brandenburg, East Friesland and
Guelderland, and the fourth of the remaining provinces. Our readers
will find that, on this arrangement, the division which, on Mr Sadler's
principle, ought to be second in fecundity stands higher than that which
ought to be first; and that the division which ought to be fourth stands
higher than that which ought to be third. We will give the result in one
view.

The number of births to a marriage is--

In those provinces of Prussia where there are fewer than
1000 people on the square league.......................4.72

In the province in which there are 1175 people on the
square league..........................................5.10

In the provinces in which there are from 1190 to 2083
people on the square league............................4.10

In the provinces in which there are from 2314 to 3461
people on the square league............................4.27

We will go no further with this examination. In fact, we have nothing
more to examine. The tables which we have scrutinised constitute the
whole strength of Mr Sadler's case; and we confidently leave it to our
readers to say, whether we have not shown that the strength of his case
is weakness.

Be it remembered too that we are reasoning on data furnished by Mr
Sadler himself. We have not made collections of facts to set against
his, as we easily might have done. It is on his own showing, it is out
of his own mouth, that his theory stands condemned.

That packing which we have exposed is not the only sort of packing which
Mr Sadler has practised. We mentioned in our review some facts relating
to the towns of England, which appear from Mr Sadler's tables, and which
it seems impossible to explain if his principles be sound. The average
fecundity of a marriage in towns of fewer than 3000 inhabitants is
greater than the average fecundity of the kingdom. The average fecundity
in towns of from 4000 to 5000 inhabitants is greater than the average
fecundity of Warwickshire, Lancashire, or Surrey. How is it, we asked,
if Mr Sadler's principle be correct, that the fecundity of Guildford
should be greater than the average fecundity of the county in which it
stands?

Mr Sadler, in rep
