We agree with Mr. COOPER, entirely, in very many of his views in relation to the society and manners of England and America. The ridiculous affectation of simplicity, the heartlessness and the flippancy of the English, whom he met in society, are defects which lay them bare to the lash, and the lash has been well laid on. This putting a rein upon the lungs, and drilling of muscles to order, for mere fashion's sake, is a legitimate theme for satire; and we are glad to see, by the squirming of the malevoli among the English critics, who are nibbling away at the excrescences of the work, that our author's random shots have '_told_' well. Mr. COOPER is equally just and felicitous in many of his comments upon American society. The mere tyranny of public opinion he sets forth in its true light. He very justly, too, repudiates the influence of those among us, whose narrow souls never moved in a wider circle than the circumference of a dollar, and who carry their brains in their pockets; and he ridicules, with proper motives and good grounds, the American propensity to use 'great swelling words' to express the commonest ideas, or merest matters of fact, which he illustrates by a characteristic anecdote. A rail-car companion, at Bordentown, who wished to say, 'They have laid the foundations of a large building here,' oracularly observed, instead: 'Judging from external symptoms, they have commenced the construction, in this place, of an edifice of considerable magnitude, calculated, most likely, to facilitate the objects of the rail-road company!' This lingual magniloquence is proverbial of American parvenus. Some months since, just as that sweet singer, Mrs. AUSTIN, was leaving New-York in the steam-boat for a Liverpool packet, lying in the stream, some inflated personage called out: 'It is proposed to pay a parting tribute to the distinguished vocalist who has, by her fine powers of music, so long delighted our citizens, and who is now about to depart from us!' 'Three cheers for Mrs. AUSTIN!' would have been understood, and heartily responded to; but this rigmarole only induced a sort of bastard applause, which fell feebly on the ear, and sent its prompter away, covered with confusion. Our author's repeated sneers at the public press, and literary men, coming from one who is a writer by profession, and sucks his sustenance through a quill, is in exceeding bad taste; and his allusion to New-England editors, constitutes a characteristic specimen of aimless spite, which is quite beneath a person of his standing as an author. Some one native of New-England, obnoxious, from some cause, to Mr. COOPER, is undoubtedly at the bottom of this sweeping allusion. Had we that honor, or had we leisure, we should be glad to show _who_ are the men whom Mr. COOPER would thus traduce, _en masse_.
