We observe that Mr Cardwell, in a late speech delivered by him in the House of Commons, reasserts, in pretty strong terms, his belief in the prosperity of the country, and dwells especially upon the cheering fact that the exports and imports have increased. Now, as he is one of the representatives of Liverpool, and ought to know something about mercantile matters, we beg to call his attention to the foregoing article, which surely is specific enough to admit of refutation, if it is not consistent with the truth. There has been, of late, a great deal of babble about prosperity, but no proof of its existence. This is an easy way, no doubt, of disposing of the question; and it may succeed with people who are not accustomed to watch the flux of public events, and the rise and fall of commerce. It is not difficult to deal in general terms and rounded periods, or to make broad averments, without substantiating them, in a parliamentary speech; but it is full time that the public should be led to discriminate between what is matter of fact and what is matter of opinion. We submit a statement from Liverpool to the notice of the member for Liverpool. It contains allegations which, if true, show that the large and important mercantile constituency which he represents is very far from sharing in that general prosperity which he believes to exist somewhere. In the language of a late eminent statesman, three courses are open to Mr Cardwell. He can either deny the statement of our correspondent, in which case we shall be glad to be furnished with a refutation; or, he may admit the statement, in which case nothing more need be said on the subject; or he may maintain a dignified silence, in which case he must pardon us if we arrive at the conclusion that, in reality, he knows very little about the matter--and so we commend him to his constituents.] THE MOTHER'S LEGACY TO HER UNBORN CHILD. _The Mothers Legacie to her Vnborne Childe._ By ELIZABETH IOCELINE.
