From FRANCE the political news is of little moment, or at least is without any distinguishing event. The project for a revision of the constitution having failed, all parties are preparing for the important event of electing a new President. The Prince Joinville may be considered to be in the field as the representative of the Bourbon dynasty; and it is probable that the real conflict will be fought between the adherents of Napoleon and those of the exiled monarchy. A majority of the Councils of Arrondissement--according to some, a majority of no less than two thirds--have decided against any revision of the Constitution. At Lyons a conspiracy against the state was discovered, its leaders arrested, and their trial has excited much attention. Their object it is said was to give the south-eastern departments of France a secret organization, sufficiently strong and complete to enable them to break out in simultaneous insurrection on a given signal; to secure the frontier of Switzerland and of Savoy as a means of assistance or retreat; to support the French movement by the advance of the refugees collected at Geneva; to take possession, if possible, of the ports of Toulon and Marseilles, and thus to command Algiers and the fleet; to inflame by this insurrection the south-eastern provinces pledged to the movement, and subsequently the eastern departments supposed to be favorable to it; and thus to lead to a general republican rising throughout the country, especially where the garrisons--were weakest. The prisoners were tried by a council of war, and their council in the course of the trial threw up their briefs in despair of obtaining a fair inquisition. Three of the prisoners, M. Gent, their leader, who had been conspicuous in affairs during the provisional government, and Longomazino, and Ode--were condemned to deportation; thirteen to detention for terms from three to fifteen years as felons, with police surveillance for life; nine to imprisonment for short terms; eleven were acquitted, besides ten who were condemned, and two acquitted by default. The punishment of deportation is the highest penalty for political offences now known to the French law, and has been expressly substituted by a recent enactment for the punishment of death. It consists in transportation to Nonkahiva or Vuitkan, in the Marquesas, the most desolate islands in the Pacific Ocean, one day to be peopled, as an enterprising public writer has observed, with the chiefs and leaders of political parties in France. At Paris, on the 31st of August, 125 persous were arrested, charged with a conspiracy against the State. Among the number was an advocate, named Maillard, formerly Secretary to Ledru Rollin. Rollin is said to be implicated in the conspiracy. A general Socialist Revolution was the object of the conspiracy. There was less excitement upon the subject in Paris than might have been anticipated. It is reported that an expedition
