The French National Assembly met on the 9th for the last time of the session, and then adjourned until the 4th of November. A manifesto was at once issued by the Republican members, complaining that the sovereign power was in the hands of men opposed to all reforms, but predicting a certain victory as the fruit of union, perseverance, and devotedness on the part of the people. The document declares that the Constitution is the supreme law, and must be maintained inviolate; and that any attempt to re-elect Bonaparte, or to prolong existing powers, will not be a crisis, but a revolution; that resistance to all such attempts will be "legitimate as right, holy as justice, sacred as liberty;" and that the Republican members, under the flag of the Constitution, will not fail in any of the duties which the salvation of the Republic may impose upon them. Preparations for the coming Presidential election are in active progress. The Orleanists seem to be settling down upon the Prince de Joinville as their candidate, and several of the most distinguished among them, recently paid a visit to the Duke of Nemours to ascertain the feelings of the family in regard to it. The conversation seems not to have been very satisfactory: the most that the Duke would say was, that they would not be responsible for the action of their friends. The Republicans have not yet fixed upon a candidate. Public attention in France has been drawn to the trial at Lyons of a number of persons charged with conspiracy. It seems that in November last a club was discovered there, of which a person named Gent was a leading member. His plan is said to have been to give the southern provinces a thorough secret organization, so as to enable them to rise on a given signal, to secure the frontiers of Switzerland and Savoy as a means of assistance or retreat, and to take steps to inflame the whole country, and thus bring about a general republican movement. The trial had not been concluded at our last advices. A singular accident occurred at the funeral ceremonies of Marshal Sebastiani, at the Invalides in Paris, on the 13th. The flame of a wax candle was brought in contact with the hangings of the catafalque, and the whole splendid drapery of the church was speedily in a blaze. Before the fire could be extinguished, nearly one half of the magnificent collection of trophies taken by the French armies were destroyed.
