A solution of spermaceti in sulphuric ether tinged with alkanet root, which solidifies at 50 degrees F., and melts and boils with the heat of the hand, is described in Beckmann's History of Inventions, Vol. II., page 121. Dennison's No. 2 sealing wax may be melted in the flame of a candle and, while still blazing, dropped upon the tongue without causing a burn, as the moisture of the tongue instantly cools it. Care must be used, however, that none touches the hands or lips. It can be chewed, and apparently swallowed, but removed in the handkerchief while wiping the lips. The above is the method practiced by all the Fire-Eaters, and absolutely no preparation is necessary except that the tongue must be well moistened with saliva. Barnello once said, "A person wishing to become a Fire-Eater must make up his or her mind to suffer a little at first from burns, as there is no one who works at the business but that gets burns either from carelessness or from accident." This is verified by the following, which I clip from the London Globe of August 11th, 1880: Accident to a Fire-Eater. A correspondent telegraphs: A terrible scene was witnessed in the market place, Leighton Buzzard, yesterday. A travelling Negro fire eater was performing on a stand, licking red-hot iron, bending heated pokers with his naked foot, burning tow in his mouth, and the like. At last he filled his mouth with benzolene, saying that he would burn it as he allowed it to escape. He had no sooner applied a lighted match to his lips than the whole mouthful of spirit took fire and before it was consumed the man was burned in a frightful manner, the blazing spirit running all over his face, neck and chest as he dashed from his stand and raced about like a madman among the assembled crowd, tearing his clothing from him and howling in most intense agony. A portion of the spirit was swallowed and the inside of his mouth was also terribly burnt. He was taken into a chemist's shop and oils were administered and applied, but afterwards in agonizing frenzy he escaped in a state almost of nudity from a lodging house and was captured by the police and taken to the work-house infirmary, where he remains in a dreadful condition. REMEMBER! Always have a large blanket at hand to smother flames in burning clothing--also a bucket of water and a quantity of sand. A siphon of carbonic water is an excellent fire extinguisher. The gas of gasoline is heavier than air, so a container should never be held ABOVE a flame. Keep kerosene and gasoline containers well corked and at a distance from fire. Never inhale breath while performing with fire. FLAME DRAWN INTO THE LUNGS IS FATAL TO LIFE. So much for the entertaining side of the art. There are, however, some further scientific principles so interesting that I reserve them for another chapter.
