Italy is fermenting with the elements of revolution. The bandits, who have been committing such depredations in the Roman States, are not robbers, it now appears, but revolutionary bands. Their extermination is almost impossible, on account of the secrecy and adroitness with which the peasants are enrolled into the service of their chief, Il Passatore. They only meet at a general rendezvous, when some important expedition is contemplated, and afterwards return to their own avocations. They receive regular pay from the moment of their enlistment, and as the links of the organization extend over a wide extent of country, the system must require a considerable amount of money. It is conjectured that this band is the preparative of a political revolution, instigated by the agents of Mazzini. In Lombardy the most severe restrictions have been issued by Radetsky. An interdict has been laid upon a hat of particular form, and a republican song in favor of Mazzini. The populace, however, inserted the name of Radetsky in place of the triumvir, and now sing the song with impunity. A plot has been discovered among the aristocratic party of Piedmont, to deliver the country into the hands of the Absolutists. The army of the kingdom is to be put upon a war footing. Washington's birthday was celebrated in Rome, with interesting ceremonies. About one hundred Americans met in the Palazzo Poli, where they partook of a splendid banquet, at which Mr. Cass, the U. S. Chargé, presided.

In Norway the Thirteenth Storthing, or National Assembly, has been opened by King Oscar. In his speech, he spoke of the tranquillity which the Scandinavian Peninsula had enjoyed, while the other nations of Europe had been convulsed with revolutions, and warned the people against delusive theories and ideas which lead only to discontent with existing relations. He also recommended the construction of a railroad from the city of Christiana to Lake Mjösen. Several serious riots have taken place in Stockholm, and Drontheim, in Norway. On February 14th, the students of the University of Upsala, to the number of 500, paraded the streets of Stockholm, and were not dispersed till a collision took place between them and the police. The same scenes were renewed next day, when the students were joined by the people; the streets were cleared by squadrons of cavalry, and the principal rioters arrested.

The dispute between Turkey and Egypt is still far from being settled. Abbas Pacha, however, is not at present in a condition to come to an open rupture with the Sublime Porte, and these differences will probably be quietly settled. The Pacha is also involved in a dispute with the French Consul-General, in relation to the claims of certain French officers, who were dismissed from the Egyptian service before the expiration of their terms. Late advices from Constantinople state that a definite arrangement has been made with regard to the Hungarian refugees. The Emperor of Austria has granted a full amnesty to all except eight, among whom are Kossuth and Bathyany, on condition that they shall make no attempt to return to Hungary. The eight proscribed persons are to remain at Kutahya until further orders. General Dembinski had reached Constantinople, where he was well received, and would shortly leave for Paris.

BRITISH AMERICA.

An interesting election has just been held in the county of Haldimand, Canada West, to supply a vacancy in the Canadian Parliament, occasioned by the death of David Thompson, Esq. There were four candidates, one of whom was the noted William Lyon Mackenzie, leader of the Rebellion of 1837. The election resulted in the choice of Mackenzie, who, after an exile of twelve years, resumes his seat in the Legislative Assembly. The Government had previously recognized his claim for $1,000, with interest, for services rendered antecedent to the rebellion. The annexation feeling is reviving in some portions of Lower Canada. At a public meeting recently held in the county of Huntingdon, several of the speakers expressed themselves very strongly in favor of annexation to the United States. The Catholic clergy oppose the movement. One of the leading Canadian politicians has drawn up a scheme of Federal Union for the British Provinces, including the Hudson's Bay Company's Territories, modelled on the federal system of the United States. The Canadian Government recently had under consideration the expediency of closing the Welland Canal against American vessels, on account of the refusal of the United States Government to adopt reciprocity measures. This course, which would seriously injure our commercial interests on the Lakes, has not yet been pursued, and the Government will probably abandon the idea.

MEXICO.

The administration of Gen. Arista is still a subject of much interest and some curiosity. According to the representations of his friends, he is about to take a firm stand in the accomplishment of his leading measures; while, on the other hand, he is charged with weakness and subjection to the influence of irresponsible favorites. Our latest accounts from the Mexican capital predict that the Government will soon be in a state of great embarrassment. The American indemnity money was nearly spent, and there was already a deficiency of near $2,000,000 in the Treasury. In consequence of the many robberies recently committed in and around the city of Mexico and on the road to Vera Cruz, the most stringent measures have been adopted for the preservation of order. Congress is still in session, but has made no modification in the Tariff bill, as was anticipated. It is feared that the Tehuantepec Railroad Treaty will be rejected, notwithstanding that Arista is known to be strongly in its favor. The exclusive privilege of a railroad from Vera Cruz to Medellin, has been granted for one hundred years to Don José Maria Estera.

The revolutionary difficulties in the State of Oaxaca, have not yet been settled. A treaty was made not long since, between Muñoz, the Governor of the State, and the rebel, Melendez, which gave great offence to the people. In order to reinstate himself in their favor, Muñoz pretended that the treaty had been violated on the part of Melendez, marched against him, and drove him and his followers into the mountains of Chimalapa, where he has since remained concealed. The Tehuantepec Surveying Expedition is now encamped at La Ventosa, a port on the Pacific. The route of the Railroad across the mountains has not yet been decided upon, the survey being a matter of difficulty on account of the dense forests with which the country is covered.

In Yucatan, the war between the Spanish and Indian races is raging with great ferocity. The Indians, who are supplied with arms and ammunition by the English at Belize, have advanced to within thirty miles of Merida, where a line of defence has been established by the Spaniards. Fourteen thousand soldiers are there opposed to more than twenty thousand Indians, and the subjugation of the latter, without help from abroad, is impossible. The troops of Yucatan are destitute of clothing and supplies, and as most of the wealthy citizens of the State have been reduced to beggary by these reverses, the threatened extermination of the Spanish race seems near at hand. A conspiracy to burn the city of Merida, formed by some of the soldiers, in conjunction with the convicts in the city prison, was discovered but a short time before it was to have been carried into effect. The conspirators were condemned to death.
