WE have no doubt that by this time it is pretty generally understood, that we have an engagement to fulfil, with the co-operation which, for the present, requires our almost constant attentions. We offer this as an excuse, partly for some very excellent extracts from the press, which our readers will accept, together with our best wishes. We also indulge in the hope that in our Geological researches among the islands of the sea, that we shall make some valuable discoveries which will be of use to the inhabitants of the earth, and to the dwellers in Gotham in particular. ------------------------------------ A CAPITAL HOAX.—Some men plagiarise the thoughts of others, without being at all aware of the pungency of the fact as regards themselves. The _Herald_, in alluding to a few of the “minor press,” gotten up and “spiced” precisely as the _Herald_ itself originally was, when it first attracted public attention, remarked: “These fellows must be taught that they cannot use the liberty of the press so far as to make it the vehicle of their dirty thoughts and dirtier expressions, and that an honorable profession is not to be degraded because they hang upon its skirts, like foul birds hovering over their prey.” The beauty of it is, this extract is, word for word, the language employed by the _Courier and Enquirer_, in March, 1842, in relation to the _Herald_ itself!—_Mercury._ ------------------------------------ FRANK LESLIE AGAIN ARRESTED. RICH SCENE AT THE TOMBS! [_From the Sunday Times._] Frank Leslie was again arrested yesterday morning, on complaint of Aldermen Reed and Tuomy. The officer told Mr. Leslie that his orders were imperative to take him at once before Justice Osborne at the Tombs, without allowing him to send for counsel or seek for bail. On arriving at the Tombs, they were met by Aldermen Tuomy and Reed, accompanied by Mr. John Graham, their counsel. Justice Osborne asked Mr. Leslie if he demanded an examination. Mr. Leslie stated that he had not been allowed time to send for his counsel, and did not know what course to pursue. Justice Osborne said he could have time to send for counsel and for bail. Mr. Graham then produced the complaints. That of Alderman Reed set forth that Mr. Leslie had published a picture representing him in the garb of a butcher, with a party of Irishmen driving a miserable and diseased-looking cow, without tail or horns, up to his stall. The leader of the party, Mr. Mike O’Flannagan, is represented as saying: “I read you tould the aldermen t’other day that swill-fed beef was worth half a cent a pound more than any other kind of meat. Here’s a beauty, yer honor; doesn’t he look fat and luscious? Arrah! don’t yer eyes wather to look at it?—Here’s the baste; we’ve brought it on purpose fer yez. Hand us over the dimes!”
