THE DEMOCRATIC LEAGUE.--Amongst all the papers and pamphlets issued from the press during our present war, none, perhaps, have exercised a more salutary influence than those emanating from this association. The article entitled SLAVERY AND NOBILITY vs. DEMOCRACY was originally published in this periodical for July, 1862. Pronounced by critics to be among the best magazine articles ever appearing in print, it commanded a very marked attention as an exposition of the atrocious motives that underlaid the great Southern rebellion. The public mind was startled at the developed evidence of a great conspiracy to subvert the fundamental principles of free government in the South. The coalition between the conspirators of the South and their allies amongst the aristocracy of England was laid bare, whilst a great portion of the English press and reviews was shown to be suborned into the service of the most atrocious objects and purposes that ever disgraced the annals of civilization. This article, whilst it elucidated to our own countrymen the secret motives of the rebellion, assisted powerfully to bring a new phase over a perverted English public opinion. The result has been that the vitiated disposition of the English aristocracy to assist the rebels, through intervention, has slunk away before British morality, and is now seen only in aid of piracy on our commerce. Following this masterly production, the speech of Mr. Sherwood at Champlain was a renewed onslaught upon the anti-democratic coalition. In this speech the most irrefragable evidence, drawn from the recitals in the records of treason, is produced against the conspirators. The perusal of this speech leaves the mind in no doubt as to the purpose of the traitors to overthrow democratic government in the South, and to establish a new form of government, based on exclusion of the democratic principle, and resting on a cemented slave aristocracy. These, amongst other papers of the Democratic League, are so replete with the evidence by which their positions are fortified, and so comprehensive in the scope and magnitude of subjects of which they treat, that they must take a high position in the political literature of the day. The manifold opinions of the press demonstrate how highly they are appreciated. They are now being reproduced in THE IRON PLATFORM, published by Wm. Oland Bourne, 112 William street, New York, and intended for extensive circulation in the cheapest form. BOOKS RECEIVED. THE CHRISTIAN EXAMINER for May, 1863. Boston: By the proprietors, Thomas B.
