cording to the first alarm given by the Essay. Again, the advance of civilization and of population in consequence with the same degree of moral restraint (as there exists in England at this present time, for instance) is a good, and not an evil--but this does not appear from the Essay. The Essay shews that population is not (as had been sometimes taken for granted) an abstract and unqualified good; but it led many persons to suppose that it was an abstract and unqualified evil, to be checked only by vice and misery, and producing, according to its encouragement a greater quantity of vice and misery; and this error the author has not been at sufficient pains to do away. Another thing, in which Mr. Malthus attempted to _clench_ Wallace's argument, was in giving to the disproportionate power of increase in the principle of population and the supply of food a mathematical form, or reducing it to the arithmetical and geometrical ratios, in which we believe Mr. Malthus is now generally admitted, even by his friends and admirers, to have been wrong. There is evidently no inherent difference in the principle of increase in food or population; since a grain of corn, for example, will propagate and multiply itself much faster even than the human species. A bushel of wheat will sow a field; that field will furnish seed for twenty others. So that the limit to the means of subsistence is only the want of room to raise it in, or, as Wallace expresses it, "a limited fertility and a limited earth." Up to the point where the earth or any given country is fully occupied or cultivated, the means of subsistence naturally increase in a geometrical ratio, and will more than keep pace with the natural and unrestrained progress of population; and beyond that point, they do not go on increasing even in Mr. Malthus's arithmetical ratio, but are stationary or nearly so. So far, then, is this proportion from being universally and mathematically true, that in no part of the world or state of society does it hold good. But our theorist, by laying down this double ratio as a law of nature, gains this advantage, that at all times it seems as if, whether in new or old-peopled countries, in fertile or barren soils, the population was pressing hard on the means of subsistence; and again, it seems as if the evil increased with the progress of improvement and civilization; for if you cast your eye at the scale which is supposed to be calculated upon true a
