inaccurate. In his book on the Law
of Population, he tells us that "in the slave-holding States of America,
the male slaves constitute a decided majority of that unfortunate
class." This fact we turned against him; and, forgetting that he had
himself stated it, he tells us that "it is as erroneous as many other
ideas which we entertain," and that "he will venture to assert that the
female slaves were, at the nubile age, as numerous as the males." The
increase of the negroes in the United States puzzles him; and he creates
a vast slave-trade to solve it. He confounds together things perfectly
different; the slave-trade carried on under the American flag, and
the slave-trade carried on for the supply of the American soil,--the
slave-trade with Africa, and the internal slave-trade between the
different States. He exaggerates a few occasional acts of smuggling into
an immense and regular importation, and makes his escape as well as he
can under cover of this hubbub of words. Documents are authentic and
facts true precisely in proportion to the support which they afford
to his theory. This is one way, undoubtedly, of making books; but we
question much whether it be the way to make discoveries.

As to the inconsistencies which we pointed out between his theory and
his own tables, he finds no difficulty in explaining them away or facing
them out. In one case there would have been no contradiction if, instead
of taking one of his tables, we had multiplied the number of three
tables together, and taken the average. Another would never have existed
if there had not been a great migration of people into Lancashire.
Another is not to be got over by any device. But then it is very small,
and of no consequence to the argument.

Here, indeed, he is perhaps right. The inconsistencies which we noticed,
were, in themselves, of little moment. We give them as samples,--as
mere hints, to caution those of our readers who might also happen to be
readers of Mr Sadler against being deceived by his packing. He complains
of the word packing. We repeat it; and, since he has defied us to the
proof, we will go fully into the question which, in our last article, we
only glanced at, and prove, in such a manner as shall not leave even to
Mr Sadler any shadow of excuse, that his theory owes its speciousness to
packing, and to packing alone.

That our readers may fully understand our reasoning, we will again state
what Mr Sadler's proposition is. He a
