It seems almost miraculous that Napoleon should have escaped the innumerable conspiracies which at this time were formed against him. The partisans of the Bourbons though that if Napoleon could be removed, the Bourbons might regain their throne. It was his resistless genius alone, which enabled France to triumph over combined Europe. His death would leave France without a leader. The armies of the allies could then, with bloody strides, march to Paris, and place the hated Bourbons on the throne. France knew this, and adored its preserver. Monarchical Europe knew this, and hence all the engergies of its combined kings were centred upon Napoleon. More than thirty of these consipracies were detected by the police. London was the hot-house where they were engendered. Air-guns were aimed to Napoleon. Assassins dogged him with their poniards. A bomb-shell was invented, weighing about fifteen pounds, which was to be thrown in at his carriage-window, and which exploding by its own concussion, would hurl death on every side. The conspirators were perfectly reckless of the lives of others, if they could only destroy the life of Napoleon. The agents of the infernal-machine had the barbarity to get a young girl fifteen years of age to hold the horse who drew the machine. This was to disarm suspicion. The poor child was blown into such fragments, that no part of her body. excepting the feet, could afterwards be found. At last Napoleon became aroused, and declared that he would "teach those Bourbons that he was not a man to be shot at like a dog." One day at St. Helena, as he was putting on his flannel waistcoat, he observed Las Casas looking at him very steadfastly. "Well! what is your Excellency thinking of?" said Napoleon, with a smile. "Sire," Las Casas replied, "in a pamphlet which I lately read, I found it stated that your majesty was shielded by a coat-of-mail, for the security of your person. I was thinking that I could bear positive evidence that at St. Helena at least, all precautions for personal safety have been laid aside."
