Then he melted pitch and wax with sulphur, which he drank down as it flamed: I saw it flaming in his mouthe a good while; he also took up a thick piece of iron, such as laundresses use to put in their smoothing-boxes, when it was fiery hot, held it between his teeth, then in his hand, and threw it about like a stone; but this I observ'd he cared not to hold very long. Then he stoode on a small pot, and, bending his body, tooke a glowing iron with his mouthe from betweene his feete, without touching the pot or ground with his hands, with divers other prodigious feats. The secret methods employed by Richardson were disclosed by his servant, and this publicity seems to have brought his career to a sudden close; at least I have found no record of his subsequent movements. About 1713 a fire-eater named De Heiterkeit, a native of Annivi, in Savoy, flourished for a time in London. He performed five times a day at the Duke of Marlborough's Head, in Fleet Street, the prices being half-a-crown, eighteen pence and one shilling. According to London Tit-Bits, "De Heiterkeit had the honor of exhibiting before Louis XIV., the Emperor of Austria, the King of Sicily and the Doge of Venice, and his name having reached the Inquisition, that holy office proposed experimenting on him to find out whether he was fireproof externally as well as internally. He was preserved from this unwelcome ordeal, however, by the interference of the Duchess Royal, Regent of Savoy." His programme did not differ materially from that of his predecessor, Richardson, who had antedated him by nearly fifty years. By far the most famous of the early fire-eaters was Robert Powell, whose public career extended over a period of nearly sixty years, and who was patronized by the English peerage. It was mainly through the instrumentality of Sir Hans Sloane that, in 1751, the Royal Society presented Powell a purse of gold and a large silver medal. Lounger's Commonplace Book says of Powell: "Such is his passion for this terrible element, that if he were to come hungry into your kitchen, while a sirloin was roasting, he would eat up the fire and leave the beef. It is somewhat surprising that the friends of REAL MERIT have not yet promoted him, living as we do in an age favorable to men of genius. Obliged to wander from place to place, instead of indulging himself in private with his favorite dish, he is under the uncomfortable necessity of eating in public, and helping himself from the kitchen fire of some paltry ale-house in the country." His advertisements show that he was before the public from 1718 to 1780. One of his later advertisements runs as follows: SUM SOLUS Please observe that there are two different performances the same evening, which will be performed by the famous MR. POWELL, FIRE-EATER, FROM LONDON:
