Fieschi's experiment with his infernal machine created a sensation all over Europe; and the papers for some time afterwards were full of particulars, more or less authentic, of the diabolical attempt upon King Louis Philippe's life. The Revolutionists, whose action against Charles X. had led to the establishment, not of a Republic, but of a Monarchy--hateful to them in whatever form--had evidently sworn that he should die. It was ascertained by M. Thiers, the First Minister, that on the occasion of a journey which the King intended to make from Neuilly to Paris certain conspirators had arranged to throw a lighted projectile into the royal carriage; and His Majesty, therefore, was requested to let the royal carriage proceed on its way, at the appointed time, without him, and occupied simply by his aides-de-camp, no previous announcement being made as to the absence of the King. Louis Philippe having protested against this suggestion as unfair to the aides-de-camp: "Sire," replied M. Thiers, "it is their duty to expose themselves for the safety of your person, and they surely will not complain when they find the Minister of the Interior by their side in the threatened carriage." The King, however, rejected this proposition, declaring that he had resolved on the journey, and, hazardous as it might be, would undertake it. His resolution having been combated in vain by M. Thiers, the preparations for departure were ordered. Just as the King was about to get into the carriage, the Queen and the princesses suddenly presented themselves in an agony of terror and of tears. "It is impossible," says M. Louis Blanc, "to say whether a skilful indiscretion on the part of the Minister had initiated them into the secret of what had taken place, or whether they had received no other intimation than that supplied by the instincts of the heart." However this may have been, the Queen, finding that Louis Philippe would not abandon his intention, insisted on accompanying him, and it was quite impossible to prevent her from doing so. M. Thiers then begged the honour of a seat in the threatened carriage, and the journey was risked. The attack apprehended was not, however, on this occasion to be made; and it was as long afterwards as the 28th of July, 1835, on the occasion when Louis Philippe drove through Paris in memory of the "Three Days" of July, 1830, that Fieschi put his murderous project into execution. "On the 28th of July," says M. Louis Blanc, "the sun rose upon the city, already perplexed with fears and doubts. The drum which summoned the National Guards early in the morning beat for some time in vain: a heavy apathy, in which there mingled a sort of morbid distrust, weighed upon everyone. At ten o'clock, however, the legions of the Garde Nationale stretched in an immense line along the boulevards, facing 40,000 of the regular troops, horse and foot. The Boulevard du Temple having been pointed out by rumour as the scene of the contemplated crime, the police
