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, {295}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-- “_In Warwickshire, far above half the population is comprised in large towns, including, of course, the immense metropolis of one great branch of oui’ manufactures, Birmingham. In the county of Stafford, besides the large and populous towns in its iron districts, situated so close together as almost to form, for considerable distances, a continuous street; there is, in its potteries, a great population, recently accumulated, not included, indeed, in the towns distinctly enumerated in the censuses, but vastly exceeding in its condensation that found in the places to which the Reviewer alludes. In Lancashire again, to which he also appeals, one-fourth of the entire population is made up of the inhabitants of two only of the towns of that county; far above half of it is contained in towns, compared with which those he refers to are villages; even the hamlets of the manufacturing parts of Lancashire are often far more populous than the places he mentions. But he presents us with a climax of absurdity in appealing lastly to the population of Surrey as quite rural compared with that of the twelve towns, having less than 5000 inhabitants in their respective jurisdictions, such as Saffron-Walden, Monmouth, &c. Now, in the last census, Surrey numbered 398,658 inhabitants, and, to say not a word about the other towns of the county, much above two hundred thousands of these are within the Bills of mortality! ‘We should, therefore, be glad to know’ how it is utterly inconsistent with my principle that the fecundity of Guildford, which numbers about 3000 inhabitants, should be greater than the average fecundity of Surrey, made up, as the bulk of the population of Surrey is, of the inhabitants of some of the worst parts of the metropolis? Or why the fecundity of a given number of marriages in the eleven little rural towns he alludes to, being somewhat higher than that of an equal number, half taken for instance, from the heart of Birmingham or Manchester, and half from the populous districts by which they are
