DISCOVERY OF A REPUBLICAN CONSPIRACY AT ROME—FINE AliT GOSSIP, &c.  ROME, Nov. 24.—Another of those fatal conspiracies of the Republican party has a few days since been discovered and frustrated. The particulars of it have nob transpired as yet. Arrests in great numbers are being made by day and night, and so many " compromised " are still untaken, that the police keep the matter as quiet as its importance admits of. One of the leaders in the conspiracy, indeed the chief, is a man named Mancini, who was convicted of capital crimes committed during the last Republic in Rome, but affected insanity with such success as to completely gull the authorities who sent him to the Bedlam of Rome. He made his escape from the mad-house some time ago, and has since that time been hiding in the house of a bellfounder, whose foundry exists in the Via Tor di Nona, on the way to the Castle St. Angelo. This bell-founder is himself an old defaulter, baying made a very free use of the Triumvirates' order to destroy the bells of the Roman churches, but on the score of extreme penitence he was subsequently pardoned by the Pope. The police were previously informed of every detail connected with the affair, and hearing of a meeting being appointed for a certain night in the house of a butcher in the Via Laurina, occupied the houses in the vicinity in great numbers, guarding all the windows and doors in front and rear At two hours after midnight, the bell-founder joined the conspirators, as had been expected by the police, who had arranged his arrival as the signal for the attack. They accordingly sallied forth in strong force, and made their way into the house with such promptitude that the party had not time to light a snatch to set fire to their papers, and one or two were caught by the throat and compelled to give out &Turnouts they were attempting to swallow. Other papers were thrown out of a window into the street, manned by the police, who possessed themselves of them, and, it is believed, have obtained intelligence of the utmost importance from them. I hope speedily to be able to say more about the matter. All I know as yet is that murder on a grand scale, as an act of intimidation, was intended as the first step in the affair. The French army of occupation being now small, in consequence of so many having been sent to the Crimea, and the Roman troops being at all times more ready to attack than to defend the Government employieg them, the conspirators were sanguine of success. You will remember, in my letters of last summer, that I mentioned the disembarkation, clandestinely, of large numbers of armed men, who separated themselves off into divisions of front 20 to 30 strong, and who, spreading out from the thickets (Macchie) adjoining the Pontine marshes, were heard of trom time to time. The day fixed for making the grand coup was the coming Bth December, being the feast in honour of the Immaculate Conception of the Blessed Virgin, which is to be held with more than ordinary solemnity and splendour at the Lateran Basilica, as a finale or windup to the year of devotion and thanksgiving, celebrated all over the Catholic world, but especially in Rome.
