“Did you see Madame Blanchard fall?” said he. “I saw her; yes, I! I was at Tivoli on the 6th of July, 1819. Madame Blanchard rose in a small sized balloon, to avoid the expense of filling, and she was forced to entirely inflate it. The gas leaked out below, and left a regular train of hydrogen in its path. She carried with her a sort of pyrotechnic aureola, suspended below her car by a wire, which she was to set off in the air. This she had done many times before. On this day she also carried up a small parachute ballasted by a firework contrivance, that would go off in a shower of silver. She was to start this contrivance after having lighted it with a port-fire made on purpose. She set out; the night was gloomy. At the moment of lighting her fireworks she was so imprudent as to pass the taper under the column of hydrogen which was leaking from the balloon. My eyes were fixed upon her. Suddenly an unexpected gleam lit up the darkness. I thought she was preparing a surprise. The light flashed out, suddenly disappeared and reappeared, and gave the summit of the balloon the shape of an immense jet of ignited gas. This sinister glow shed itself over the Boulevard and the whole Montmartre quarter. Then I saw the unhappy woman rise, try twice to close the appendage of the balloon, so as to put out the fire, then sit down in her car and try to guide her descent; for she did not fall. The combustion of the gas lasted for several minutes. The balloon, becoming gradually less, continued to descend, but it was not a fall. The wind blew from the north-west and drove it towards Paris. There were then some large gardens just by the house No. 16, Rue de Provence. Madame Blanchard essayed to fall there without danger: but the balloon and the car struck on the roof of the house with a light shock. ‘Save me!’ cried the wretched woman. I got into the street at this moment. The car slid along the roof, and encountered an iron cramp. At this concussion, Madame Blanchard was thrown out of her car and precipitated upon the pavement. She was killed!” These stories froze me with horror. The unknown was standing with bare head, dishevelled hair, haggard eyes! There was no longer any illusion possible. I at last recognized the horrible truth. I was in the presence of a madman! He threw out the rest of the ballast, and we must have now reached a height of at least nine thousand yards. Blood spurted from my nose and mouth! “Who are nobler than the martyrs of science?” cried the lunatic. “They are canonized by posterity.” But I no longer heard him. He looked about him, and, bending down to my ear, muttered,—
