sins, preferred telling a falsehood to exaggerating; and that he has consequently underrated the number of emigrants. We will take it at double of the Doctor's estimate, and suppose that, in 1817, 45,000 Europeans crossed to the United States. Now, it must be remembered that the year 1817 was a year of the severest and most general distress over all Europe, a year of scarcity everywhere, and of cruel famine in some places. There can, therefore, be no doubt that the emigration of 1817 was very far above the average, probably more than three times that of an ordinary year. Till the year 1815, the war rendered it almost impossible to emigrate to the United States either from England or from the Continent. If we suppose the average emigration of the remaining years to have been 16,000, we shall probably not be much mistaken. In 1818 and 1819, the number was certainly much beyond that average; in 1815 and 1816, probably much below it. But, even if we were to suppose that, in every year from the peace to 1820, the number of emigrants had been as high as we have supposed it to be in 1817, the increase by procreation among the white inhabitants of the United States would still appear to be about 30 per cent. in ten years. Mr. Sadler acknowledges that Cobbett exaggerates the number of emigrants when he states it at 150,000 a year. Yet even this estimate, absurdly great as it is, would not be sufficient to explain the increase of the population of the United States on Mr. Sadler's principles. He is, he tells us, "convinced that doubling in 35 years is a far more rapid duplication than ever has taken place in that country from procreation only." An increase of 20 per cent. in ten years, by procreation, would therefore be the very utmost that he would allow to be possible. We have already shown, by reference to the census of the slave population, that this doctrine is quite absurd. And, if we suppose it to be sound, we shall be driven to the conclusion that above eight hundred thousand people emigrated from Europe to the United States in a space of little more than five years. The whole increase of the white population from 1810 to 1820 was within a few hundreds of 2,000,000. If we are to attribute to procreation only 20 per cent. on the number returned by the census of 1810, we shall have about 830,000 persons to account for in some other way;-and to suppose that the emigrants who went to America between the peace of 1815 and the census of 1820, with the children who were born to them there, would make up that number, would be the height of absurdity. We could say much more; but we think it quite unnecessary at present. We have shown that Mr. Sadler is careless in the collection of facts,—that he is incapable of reasoning on facts when he has collected them,-that he does not understand the simplest terms of science, that he has enounced a proposition of which he does not know the meaning, that the proposition which he means to enounce, and which he tries to prove, leads directly to all those consequences which he represents as impious and immoral,—and that, from the very documents to which he has himself appealed, it may be demonstrated that his theory is false. We may, perhaps, resume the subject when his next volume appears. Meanwhile, we hope that he will delay its publication until he has learned a little arithmetic, and unlearned a great deal of eloquence. 263 SADLER'S REFUTATION REFUTED. A Refutation of an Article in the Edinburgh Review (No. CII.) entitled "Sadler's Law of Population, and Disproof of Human Superfecundity," containing also Additional Proofs of the Principle enunciated in that Treatise, founded on the Censuses of different Countries recently published. By MICHAEL THOMAS SADLER, M.P. 8vo. London: 1830. "Before anything came out against my Essay, I was told I must prepare myself for a storm coming against it, it being resolved by some men that it was necessary that book of mine should, as it is phrased, be ran down."-JOHN LOCKE. WE have, in violation of our usual practice, transcribed Mr. Sadler's title-page from top to bottom, motto and all. The parallel implied between the Essay on the Human Understanding and the Essay on Superfecundity is exquisitely laughable. We can match it, however, with mottoes as ludicrous. We remember to have heard of a dramatic piece, entitled "News from Camperdown," written soon after Lord Duncan's victory, by a man once as much in his own good graces as Mr. Sadler is, and now as much forgotten as Mr. Sadler will soon be, Robert Heron. His piece was brought upon the stage, and damned, "as it is phrased," in the second act; but the author, thinking that it had been unfairly and unjustly "run down," published it, in order to put his critics to shame, with this motto from Swift: "When a true genius appears in the world, you may know him by this mark-that the dunces are all in confederacy against him." We remember another anecdote, which may perhaps be acceptable to so zealous a churchman as Mr. Sadler. A certain Antinomian preacher, the oracle of a barn, in a county of which we do not think it proper to mention the name, finding that divinity was not by itself a sufficiently lucrative profession, resolved to combine with it that of dog-stealing. He was, by ill-fortune, detected in several offences of this description, and was in consequence brought before two justices, who, in virtue of the powers given them by an act of parliament, sentenced him to a whipping for each theft. The degrading punishment inflicted on the pastor naturally thinned the flock; and the poor man was in danger of wanting bread. He accordingly put forth a handbill, solemnly protesting his innocence, describing his sufferings, and appealing to the Christian charity of the public; and to his pathetic address he prefixed this most appropriate text: "Thrice was I beaten with rods."—St. Paul's Epistle to the Corinthians. He did not perceive that, though St. Paul had been scourged, no number of whippings, however severe, will of themselves entitle a man to be considered as an apostle. Mr. Sadler seems to us to have fallen into a somewhat similar error. He should remember that, though Locke may have been laughed at, so has Sir Claudius Hunter; and that it takes something more than the laughter of all the world to make a Locke. The body of this pamphlet by no means justifies the parallel so modestly insinuated on the title-page. Yet we must own that, though Mr. Sadler has not risen to the level of Locke, he has done what was almost as difficult, if not as honourable-he has fallen below his own. He is at best a bad writer. His arrangement is an elaborate confusion. His style has been constructed, with great care, in such a manner as to produce the least possible effect by means of the greatest possible number of words. Aspiring to the exalted character of a Christian philosopher, he can never preserve through a single paragraph either the calmness of a philosopher or the meekness of a Christian. His ill-nature would make a very little wit formidable. But, happily, his efforts to wound resemble those of a juggler's snake. The bags of poison are full, but the fang is wanting. In this foolish pamphlet, all the unpleasant peculiarities of his style and temper are brought out in the strongest manner. He is from the beginning to the end in a paroxysm of rage, and would certainly do us some mischief if he knew how. We will give a single instance for the present. Others will present themselves as we proceed. We laughed at some doggerel verses which he cited, and which we, never having seen them before, suspected to be his own. We are now sure that, if the principle on which Solomon decided a famous case of filiation were correct, there can be no doubt as to the justice of our suspicion. Mr. Sadler, who, whatever elements of the poetical character he may lack, possesses the poetical irritability in an abundance which might have sufficed for Homer himself, resolved to retaliate on the person, who, as he supposed, had reviewed him. He has, accordingly, ransacked some collection of college verses, in the hope of finding, among the performances of his supposed antagonist, something as bad as his own. And we must in fairness admit that he has succeeded pretty well. We must admit that the gentleman in question sometimes put into his exercises, at seventeen, almost as great nonsense as Mr. Sadler is in the habit of putting into his books at sixty. Mr. Sadler complains that we have devoted whole pages to mere abuse of him. We deny the charge. We have, indeed, characterised, in terms of just reprehension, that spirit which shows itself in every |
