MILTON, BURKE, MAZZINI, and DANIEL WEBSTER, present the most extraordinary examples of the harmonious and effective combination of political and literary genius, that have appeared in modern times. There have been and there are now many politicians who are eminent as authors: but these are preeminently great in both statesmanship and letters. Mazzini is now the chief apostle of republicanism in Europe, as Milton was in the time of the Protector. He devises and executes the schemes which promise advances of liberty and happiness, and he is equal to the defence with the pen of every thing he essays in affairs. "Young Italy," since it was put down by French bayonets, has had as little quarter from parasite writers as from patristic governors; but Mazzini has come to her defence with as vigorous a pen as that with which Milton vindicated the people of England against the hireling Salmasius, under similar circumstances. In another part of this number of the _International_, we have copied from the London _Examiner_ a reviewal of Mazzini's work on the Italian revolution. We should be glad to see it criticised by Mr. Walsh also, or by Professor Bowen, in his _North American Review_. * * * * * Since SIR FRANCIS HEAD went home from Canada, and finished the last edition of his "Bubbles" and "Travels," and the funny anathema of poor Mr. William Lyon Mackenzie, in the _Times_, he has been very quiet, except now and then, when he has given an explosive and amusing paper in the _Quarterly_. But now he has published a new book, on "The Defenceless State of Great Britain," in which, the _Examiner_ says "he has made up for lost time." Says the critic, "It is calculated to rouse all the old women in the country. Such a fee-fa-fum of a book we never read. The Duke's letter to Sir John Burgoyne was nothing to it, and it beats even Lord Ellesmere hollow." The baronet thinks every thing portends a French invasion, and he advocates the largest "war footing." * * * * * The REV. DR. BLOOMFIELD, whose edition of the Greek Testament is so well known in this country, has just published two volumes of additional Notes, critical, philological, and explanatory, in fulfilment of a promise made in the third edition of his New Testament, in 1839. This promise was, that he would make no further change in the notes to the New Testament, but reserve all additions for a separate supplementary work. That work, after the direct labor of eleven years, is now published; forming a companion to all the editions of Bloomfield's Greek Testament except the first two. The annotations relate to a critical examination of the readings of the text, with the reasons for that selected, philological notes on the meaning of words, and exegetical annotations on the verbal interpretations of passages. * * * * *
