The difference is small, but not smaller than differences which Mr. Sadler has brought forward as proofs of his theory. We say, that these English tables no more prove that fecundity increases with the population than that it diminishes with the population. The thirty-four counties which we have taken make up, at least, four-fifths of the kingdom: and we see that, through those thirty-four counties, the phenomena are directly opposed to Mr. Sadler’s principle. That in the capital, and in great manufacturing towns, marriages are less prolific than in the open country, we admit, and Mr. Malthus admits. But that any condensation of the population, short of that which injures all physical energies, will diminish the prolific powers of man, is, from these very tables of Mr. Sadler, completely disproved.
It is scarcely worth while to proceed with instances, after proofs so overwhelming as those which we have given. Yet we will show that Mr. Sadler has formed his averages on the census of Prussia by an artifice exactly similar to that which we have already exposed.
The number of births to a marriage is—
We will go no farther 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 reply, talks about “the absurdity of comparing the fecundity in the small towns alluded to with that In the counties of Warwick and Stafford, or those of Lancaster and Surrey.” He proceeds thus—
