With regard to this I would like to record the following fact: Not many years ago there lived in Aversa, a small town near Naples, Italy, a certain Don Angelo Fontanella, a violin player, who professed himself to be the possessor of an infallible remedy against toothache. When summoned by the sufferer, he carried with him, in a bundle, a tile, a large iron plate, a funnel, a small curved tube adjustable to the apex of the funnel, a piece of bees’ wax, and a small packet of onion seed. Having placed the tile on a table, the iron plate was put upon it, after it had been heated red hot. Then the operator let a piece of bees’ wax fall upon the red-hot iron, together with a certain quantity of the onion seed; then, having promptly covered the whole with the funnel and made the patient approach, he brought the apex of the said funnel close to the sick tooth, in such a way as to cause the prodigious, if somewhat stinking, fumes produced by the combustion of the wax with the onion seed to act upon it. In the case of a lower tooth, the above-mentioned curved tube was adapted to the funnel, so that the fumes might equally reach the tooth. The remedy, for the most part, had a favorable result, whether because the beneficial effect was due to the action of the hot vapor on the diseased tooth, or to the active principles resulting from the combustion of the wax and onion seed, or to both, or perhaps also, at least in certain cases, to the suggestion that was thus brought to bear upon the sufferer. It would not be at all worth while to discuss here such a point. The interesting part is that when the patient had declared that he no longer felt the pain, Don Angelo, with a self-satisfied smile, turned the funnel upside down, and showed on its internal surface a quantity of what he pretended to be worms, which he affirmed had come out of the carious tooth. Great was the astonishment of the patient and of the bystanders, none of whom raised the least doubt as to the nature and origin of these small bodies, no one having the faintest suspicion even that these, instead of coming from the tooth, might come from the onion seed!
