"As we have already stated, we were the first to give the public the intelligence of his strange disappearance, and so intense was the interest the news excited that our printing-machines could not supply one-fourth of the demand for the various editions of our journal. The letters we received upon the subject would form a curious chapter in a new 'Curiosities of Literature.'
"'Dear sir' (wrote one correspondent), 'you speak of the disappearance of the body of M. Felix as an unparalleled incident. Allow me to correct you, and from my own experience to furnish your readers with an identical case. It is now ten years ago since I formed the acquaintance of a gentleman of great attainments and peculiar habits, and whose nationality was always a matter of curiosity with me. Once or twice I delicately approached the subject, but he skilfully evaded it, and I did not feel warranted in pressing it. He was a wonderful chess-player, an accomplished linguist, and his knowledge of the niceties of every new discovery in science was simply marvellous. He had only one failing--he drank and smoked too much. In those days I also was a free liver. We were both single men, I certainly, he presumably; there are topics upon which it is good breeding to preserve a friendly delicacy. We met frequently, and dined together at least twice a week, at my expense. He was a good judge of wine and liquor, and very choice in his food. Being much superior to me in this respect, I invariably left it to him to decide where to dine and to arrange the courses. Perhaps occasionally we took half a bottle of wine too much, but that is neither here nor there. It was no one's business but our own. He took a peculiar interest in all new inventions, and was in the habit of throwing out hints of an extraordinary invention of his own which one day was to revolutionize the world. He told me very little of his discovery of which anyone could make use, but he was so jealous of his secret that he bound me down to solemn secrecy on the point; and I trust I am too much of a gentleman to violate the confidence he reposed in me. I may, however, without scruple, reveal that his invention related to combustion. One evening, when we had arranged to dine as usual together at the Royal, in Regent Street, he confided to me that he was in temporary want of funds, and I lent him all the money I had about me, some fifteen or sixteen pounds. Then we dined, and he paid for the dinner. Over the meal he talked more frequently than he was in the habit of doing of his invention. "It is near completion," he said, "and before I go to bed I intend to make some experiments which I am in hopes will put the finishing touch to it." Then he looked at me searchingly and thoughtfully, and said I might accompany him home if I liked, and assist in the experiments. Burning with curiosity, and delighted at this mark of his confidence, I gladly consented, and we issued forth and proceeded to his rooms, which, singularly enough, were in Glasshouse Street, at no very great distance from the house in which M. Felix lived. On our way he purchased two bottles of brandy, remarking that even when the soul was in its highest state of exaltation the body required nourishment and sustaining. I acquiesced. He lived on the second floor, in two rooms, one his bedroom, the other the room in which he conducted his experiments. There was no evidences of the nature of these experiments visible, and he explained this to me by stating that, distrusting his housekeeper, he kept them in his cupboard. The first thing he did was to light a large fire; then he brought forth a brass frying-pan, upon which he emptied a packet of powder. "You must not be frightened at what I am about to do," he said. "There is no very great danger in it, but it needs courage." Being already primed with the wine we had at dinner, and with three glasses of the brandy he had purchased, I told him I was prepared for anything. Then he informed me that his experiments must be made without light from candle or lamp; so that, with the exception of the fire, we were in darkness. Then he put the brass frying-pan on the fire, and a blue vapor floated through the room. I felt a little nervous, but I would not confess it, and I helped myself to another glass of brandy, and puffed away at a very large and very strong cigar with which he presented me. He bade me sit in a particular chair by a little table (upon which he considerately placed the two bottles of brandy, one by this time half empty), and he drew around me upon the floor, which was destitute of carpet, a circle with a piece of billiard chalk, and said that as long as I did not move outside that charmed circle I should be safe.
