MR. COOPER has a new book in press which, in New-York, will produce a profounder sensation, than any he has yet written. It is entitled "The Men of Manhattan," and reveals the social condition of the city, past and present, as it is known only to the author of "The Littlepage Manuscripts." Mr. Cooper is a thorough New-Yorker; he is intimately acquainted with all the sources of her past and present and prospective greatness; and he has watched, with such emotions as none but a gentleman of the old school can feel, the infusion and gradual diffusion of those principles of plebeianism and ruffianism, from discontented improvidence, immigration, and other causes, which threaten to destroy whatever has justified the wisest pride; and to sink--not raise--all the mob of people to a common level. He has his whims, and though they have won for him little popularity, we regret that they are not shared more largely by the public, which will never appreciate his merits as a censor, until the best features of our civilization are quite obliterated. * * * * * MR. JUDD, the author of "Margaret," an original, indigenous, striking, and in many respects brilliant New-England story, and of "Philo," a crude, extravagant, ridiculous mass of versified verbiage, has lately published (through Phillips & Sampson, of Boston,) a new work entitled "Richard Edney, or the Governor's Family; a Rus-Urban Tale, simple and popular, yet cultured and noble, of morals, sentiment and life." It is worthy of the author of "Margaret." Though it evinces very little of the constructive faculty, it illustrates in every page a quick and intelligent observation, a happy talent for characterization, and great independence in speculation. * * * * * Mr. C. P. CASTANIS, formerly known in this country as an agreeable lecturer upon various subjects connected with Modern Greece, has just published (through Lippencott, Grambo & Co., of Philadelphia), a narrative of his captivity and escape during the massacre by the Turks on the Island of Scio, together with various adventures in Greece and America. * * * * * MR. E. G. SQUIER, whose large work upon American antiquities, published by the Smithsonian Institute, made for him a most desirable reputation, is now engaged in the preparation of an elaborate work upon the remains of ancient civilization in Central America, to contain the results of investigations during his recent official residence there. * * * * * NATHANIEL HAWTHORNE'S new work, "The House of Seven Gables," is in the press of Ticknor, Reed & Fields, of Boston. * * * * * MISS FENIMORE COOPER, whose beautiful work entitled "Rural Hours in America" has been so much and so justly applauded, has a new volume in the press of Putnam. * * * * *
