M. MIGNET has nearly completed his _Life and Times of Mary, Queen of Scots_, the third work on the subject produced in France within a year and a half. Mignet, however, is the most eminent person who has ever essayed this service, and he has had some peculiar and important advantages. He has made use of the collection of letters published by Prince Labanoff; of researches made in the State Paper Office of England by Mr. Tytler, and of other unpublished documents which he has himself collected, in order to form more correct opinions with regard to some of the darkest and most controverted events in the queen's life. These documents, chiefly from the archives of Spain, (to which M. Mignet was enabled to obtain access only at the express request of the French Government,) are of much importance, for they bring to light the negotiations carried on with Philip II. for the deliverance of Mary from her imprisonment--a part of her history to which previous biographers have paid little attention. * * * * * In the political literature of France a new pamphlet by CORMENIN is remarkable. It is entitled _Revision_, and its substance is this: Having recounted the history of the Republican Charter, elaborated during many months by men especially delegated to the work, and by a suffrage really universal, debated long and earnestly in the committee, amended by the eighteen delegates of the assembly, reviewed by the commission, deliberated by the chamber, discussed by the press,--M. Cormenin establishes that this constitution, so elaborately matured, if it has nothing which promises eternal duration, yet satisfies all the conditions essential to present permanence, and will well lead the nation to that moment, when, personal passion being somewhat allayed, it may be wisely and conscientiously reviewed. This is the pith of the pamphlet. It appeals to no passions, and justifies no excess, and is a notable and intelligent effort at the resolution of the question. * * * * * M. DE MARCELLUS, an old French ambassador, has published two volumes entitled _Literary Episodes in the East_. His oriental travel dates back as far as 1818, but the beautiful vision has pursued him ever since, and he knew no better way to lay it than by painting it, and making it real. The volume opens with a confession that all travel and all scenery have only reminded him most strongly of his eastern experiences, and that now, chilled with age, and hoping nothing of the future, he has especial pleasure in recurring to the past. It is a series of colloquial, familiar sketches and anecdotes, and will doubtless be a pleasant companion for the eastern tour. M. de Marcellus will follow this work with _A Collection of Popular Songs in Greece_. * * * * *
