The relations of France to Belgium are assuming a character of considerable interest and importance. The fact that most of the exiled Frenchmen found refuge in Belgium, excited the fears of the government that they would thence exert a dangerous influence upon French affairs. Strong representations were therefore made to the Belgian authorities, who have adopted every possible means of satisfying the French government, by suppressing distrusted journals, exercising strict vigilance over refugees, and ordering many of them out of the country, or away from Brussels. It is also stated that the Duke of Bassano, the new French envoy to the Belgian court, has been authorized to demand from that government the removal of the monumental lion erected by the British government to commemorate the battle of Waterloo, and to demolish the other trophies. The rumors of hostile designs on the part of Louis Napoleon, have led to the publication of an official denial in the _Moniteur_. That article states that the French government has addressed no demands whatever to foreign powers, excepting Belgium, where it was necessary, in order to prevent a system of incessant aggression. It has not armed a single soldier, neither has it done any thing to awaken the least susceptibility in its neighbors. All the views of the power in France are bent upon interior improvements. "It will not depart from its calm demeanor, except on the day when an attack shall have been made on the national honor and dignity." The London _Morning Chronicle_ states, as a fact of considerable historical interest, that, as early as 1849, Louis Napoleon distinctly solicited General Changamier to join with him in such a usurpation as he has since achieved, offering to make him Constable of France, with a million of francs a year and the palace of the Elysée for a residence; and that he was met by a peremptory refusal.
