MR. MIALL, however, uses a correct expression when he calls himself a "convert" to Homoeopathy. Science has no "converts." Scientific truths are either self-evident or demonstrable. Philosophical systems are not "denominations" or "persuasions." It is systems of another kind that exercise faith--such faith as Mr. MIALL appears to repose in Homoeopathy. To medical nonconformity, however, let MR. MIALL be welcome, if he will only suffer nonconformity of another kind to constitute him no obstacle to that "secular" education which is so needful a preservative against all manner of humbug. We say Amen to Mr. MIALL'S thanksgiving for never having experienced the effects of Homoeopathy in his own person; that is to say, never having experienced the effects of a serious illness unchecked by the quackery resorted to for its cure. * * * * * A HELP TO JEWISH EMANCIPATION. The Jews are excluded from Parliament by bigotry--but not merely by the bigotry of the House of Peers. Facts are stubborn things; they are also bigoted things: at least Matter-of-fact exhibits a remarkable bigotry in regard to the Jews. Last week, in the law reports, appeared the old story of the plucked pigeon; dissipation, horse-dealing, bill-discounting, cheating, and rascality. Bigoted Matter-of-fact, as usual, exhibited the scoundrel of the tale as a gentleman of the Hebrew persuasion. How is it, that if there is any villany, if there is any wickedness of a particularly dirty sort; a case of bill-stealing, receipt of stolen goods, fraudulent gambling, marine store-shop, or other disreputable establishment, the party chiefly implicated is sure, in the great majority of instances, to be a gentleman rejoicing in the name, slightly corrupted, of one of the prophets or patriarchs? For so it is, according to bigoted Matter-of-fact. While so much bigotry exists, a corresponding amount of prejudice must also exist, tending to obstruct the entrance of Israelites into the House of Commons. For if the bigot Matter-of-fact's assertion, that in nine cases out of ten a bill discounter, low-hell-keeper, fence, or other trader in wickedness, is a Jew, be believed, then the supposition that it is ten to one that a Jew is a rogue, is not very unreasonable. Now the Jewish community is not numerous and poor, but just the reverse; and its chiefs are wallowing in riches. Would they not take the most effectual means of getting their disabilities removed, if, by diffusing education throughout their body, they could manage to abate that bigotry of Matter-of-fact which ascribes to it so large a portion of discreditable members? * * * * * TO PROFESSOR FARADAY.
