"THE CAESARS," by De Quincy, is the last of the works by that great author issued by Ticknor, Reed, & Fields, who promise us in their beautiful typography all that the "Opium Eater" has written. "The Caesars" is a very remarkable book. * * * * * OF THE EDITION OF THE WRITINGS OF WASHINGTON by JARED SPARKS, we published some years ago in the Philadelphia _North American_ an opinion which was amply vindicated by citations and comparisons, and more recently, in the _International_ for last December, we substantially repeated our judgment in the following words, in reply to some observations on the subject in the Paris _Journal des Debats_: "But the omissions by Mr. Sparks--sometimes from carelessness, sometimes from ignorance, and sometimes from an indisposition to revive memories of old feuds, or to cover with disgrace names which should be dishonored, and his occasional verbal alterations of Washington's letters, prevent satisfaction with his edition of Washington." Since then an able and ingenious writer in the _Evening Post_ has criticised the labors of Mr. Sparks in the same manner, and in a second paper conclusively replied to his defenders. We profess thoroughly to understand this matter; we have carefully compared the original letters of Washington, as they are preserved in the Department of State, in the Charleston Library, the New-York Historical Society's Library, and in numerous other public and private collections, and we have come to the conclusion that instead of having done any service to American History by his editions of Morris, Franklin, and Washington, Mr. Sparks has done positive and scarcely reparable injury; since by his incomplete, inaccurate and injudicious publications, he has prevented the preparation of such as are necessary for the illustration of the characters of these persons and the general history of their times. We shall not at present enter into any particulars for the vindication of our dissent from the very common estimation of the character of Mr. Sparks as a historian; but we may gratify some students in our history by stating that _A Complete Collection of the Writings of Washington, chronologically arranged, and amply illustrated with Introductions, Notes, &c._, is in hand, and will be published with all convenient expedition. It will embrace about twice as much matter as the edition by Sparks, but will be much more compactly printed. It would have appeared before the present time, but for an absurd misapprehension in regard to certain assumed copyrights, which one of our most eminent justices, and several lawyers of the highest distinction, have declared null and impossible. * * * * *
