which, according to Mr
Sadler's principle, it ought to occupy.

That which ought to be highest in fecundity is tenth in one table,
fourteenth in another, and only thirty-first according to the third.
That which ought to be third is twenty-second by the table, which places
it highest. That which ought to be fourth is fortieth by the table,
which places it highest. That which ought to be eighth is fiftieth or
sixtieth. That which ought to be tenth from the top is at about the same
distance from the bottom. On the other hand, that which, according to Mr
Sadler's principle, ought to be last but two of all the eighty-four is
third in two of the tables, and seventh in that which places it lowest;
and that which ought to be last is, in one of Mr Sadler's tables, above
that which ought to be first, in two of them, above that which ought to
be third, and, in all of them, above that which ought to be fourth.

By dividing the departments in a particular manner, Mr Sadler has
produced results which he contemplates with great satisfaction. But, if
we draw the lines a little higher up or a little lower down, we shall
find that all his calculations are thrown into utter confusion; and
that the phenomena, if they indicate anything, indicate a law the very
reverse of that which he has propounded.

Let us take, for example, the thirty-two departments, as they stand in
Mr Sadler's table, from Lozere to Meuse inclusive, and divide them into
two sets of sixteen departments each. The set from Lozere and Loiret
inclusive consists of those departments in which the space to each
inhabitant is from 3.8 hecatares to 2.42. The set from Cantal to Meuse
inclusive consists of those departments in which the space to each
inhabitant is from 2.42 hecatares to 2.07. That is to say, in the
former set the inhabitants are from 68 to 107 on the square mile, or
thereabouts. In the latter they are from 107 to 125. Therefore, on Mr
Sadler's principle, the fecundity ought to be smaller in the latter set
than in the former. It is, however, greater, and that in every one of Mr
Sadler's three tables.

Let us now go a little lower down, and take another set of sixteen
departments--those which lie together in Mr Sadler's tables, from
Herault to Jura inclusive. Here the population is still thicker than
in the second of those sets which we before compared. The fecundity,
therefore, ought, on Mr Sadler's principle, to be less than in that set.
But it is again great
