He alleged, that fire was the sole vivifying principle that pervaded all nature; that, as the heat of the sun concocted the juice of vegetables, and ripened those fruits that grow upon the surface of this globe, there was likewise an immense store of central fire reserved within the bowels of the earth, not only for the generation of gems, fossils, and all the purposes of the mineral world, but likewise for cherishing and keeping alive those plants which would otherwise perish by the winter's cold. The existence of such a fire he proved from the nature of all those volcanoes, which in almost every corner of the earth are continually vomiting up either flames or smoke. "These," said he, "are the great vents appointed by nature for the discharge of that rarefied air and combustible matter, which, if confined, would burst the globe asunder; but, besides the larger outlets, there are some small chimneys through which part of the heat transpires; a vapour of that sort, I conceive, must pass through the bed or channel of this spring, the waters of which, accordingly retain a moderate warmth."

This account, which totally overthrew the other's doctrine, was so extremely agreeable to the audience, that the testy doctor lost his temper, and gave them to understand, without preamble, that he must be a person wholly ignorant of natural philosophy, who could invent such a ridiculous system, and they involved in worse than an Egyptian fog, that could not at once discern its weakness and absurdity. This declaration introduced a dispute, which was unanimously determined in favour of our adventurer. On all such occasions the stream of prejudice runs against the physician, even though his antagonist has nothing to recommend himself to the favour of the spectators; and this decision depends upon divers considerations. In the first place, there is a continual war carried on against the learned professions, by all those who, conscious of their own ignorance, seek to level the reputation of their superiors with their own. Secondly, in all disputes upon physic that happen betwixt a person who really understands the art, and an illiterate pretender, the arguments of the first will seem obscure and unintelligible to those who are unacquainted with the previous systems on which they are built; while the other's theory, derived from common notions, and superficial observation, will be more agreeable, because better adapted to the comprehension of the hearers. Thirdly, the judgment of the multitude is apt to be biassed by that surprise which is the effect of seeing an artist foiled at his own weapons, by one who engages him only for amusement.

Fathom, besides these advantages, was blessed with a flow of language, an elegant address, a polite and self-denying style of argumentation, together with a temper not to be ruffled; so that the victory could not long waver between him and the physician, to whom he was infinitely superior in every acquisition but that of solid learning, of which the judges had no idea. This contest was not only glorious but profitable to our adventurer, who grew into such request in his medical capacity, that the poor doctor was utterly deserted by his patients, and Fathom's advice solicited by every valetudinarian in the place; nor did he forfeit the character he thus acquired by any miscarriages in his practice. Being but little conversant with the materia medica, the circle of his prescriptions was very small; his chief study was to avoid all drugs of rough operation and uncertain effect, and to administer such only as should be agreeable to the palate, without doing violence to the constitution. Such a physician could not but be agreeable to people of all dispositions; and, as most of the patients were in some shape hypochondriac, the power of imagination, co-operating with his remedies, often effected a cure.

On the whole, it became the fashion to consult the Count in all distempers, and his reputation would have had its run, though the death of every patient had given the lie to his pretensions. But empty fame was not the sole fruit of his success. Though no person would presume to affront this noble graduate with a fee, they did not fail to manifest their gratitude by some more valuable present. Every day some superb piece of china, curious snuffbox, or jewel, was pressed upon him; so that, at the end of the season, he could almost have furnished a toyshop with the acknowledgments he had received. Not only his avarice, but his pleasure, was gratified in the course of his medical administration. He enjoyed free access, egress, and regress with all the females at the well, and no matron scrupled to put her daughter under his care and direction. These opportunities could not be lost upon a man of his intriguing genius; though he conducted his amours with such discretion, that, during the whole season, no lady's character suffered on his account, yet he was highly fortunate in his addresses, and we may venture to affirm, that the reproach of barrenness was more than once removed by the vigour of his endeavours.

CHAPTER THIRTY-SIX
HE IS SMITTEN WITH THE CHARMS OF A FEMALE ADVENTURER, WHOSE ALLUREMENTS SUBJECT HIM TO A NEW VICISSITUDE OF FORTUNE.

Among those who were distinguished by his gallantry was the young wife of an old citizen of London, who had granted her permission to reside at the hot well for the benefit of her health, under the eye and inspection of his own sister, who was a maiden of fifty years. The pupil, whose name was Mrs. Trapwell, though low in stature, was finely shaped, her countenance engaging, though her complexion was brown, her hair in colour rivalled the raven's back, and her eyes emulated the lustre of the diamond. Fathom had been struck with her first appearance; but found it impracticable to elude the vigilance of her duenna, so as to make a declaration of his flame; until she herself, guessing the situation of his thoughts, and not displeased with the discovery, thought proper to furnish him with the opportunity he wanted, by counterfeiting an indisposition, for the cure of which she knew his advice would be implored. This was the beginning of an acquaintance, which was soon improved to his wish; and so well did she manage her attractions, as in some measure to fix the inconstancy of his disposition; for, at the end of the season, his passion was not sated; and they concerted the means of continuing their commerce, even after their return to London.

This intercourse effectually answered the purpose of the husband, who had been decoyed into matrimony by the cunning of his spouse, whom he had privately kept as a concubine before marriage. Conscious of her own precarious situation, she had resolved to impose upon the infirmities of Trapwell, and, feigning herself pregnant, gave him to understand she could no longer conceal her condition from the knowledge of her brother, who was an officer in the army, and of such violent passions, that, should he once discover her backsliding, he would undoubtedly wipe away the stains of his family dishonour with her own blood, as well as that of her keeper. The citizen, to prevent such a catastrophe, took her to wife; but soon after perceiving the trick which had been played upon him, set his invention at work, and at length contrived a scheme which he thought would enable him, not only to retrieve his liberty, but also indemnify himself for the mortification he had undergone.

Far from creating any domestic disturbance, by upbraiding her with her finesse, he seemed perfectly well pleased with his acquisition; and, as he knew her void of any principle, and extremely addicted to pleasure, he chose proper occasions to insinuate, that she might gratify her own inclination, and at the same time turn her beauty to good account. She joyfully listened to these remonstrances, and, in consequence of their mutual agreement, she repaired to Bristol Spring, on pretence of an ill state of health, accompanied by her sister-in-law, whom they did not think proper to intrust with the real motive of her journey. Fathom's person was agreeable, and his finances supposed to be in flourishing order; therefore, she selected him from the herd of gallants, as a proper sacrifice to the powers which she adored; and, on her arrival in London, made her husband acquainted with the importance of her conquest.

Trapwell overwhelmed her with caresses and praise for her discreet and dutiful conduct, and faithfully promised that she should pocket in her own privy purse one-half of the spoils that should be gathered from her gallant, whom she therefore undertook to betray, after he had swore, in the most solemn manner, that his intention was not to bring the affair to a public trial, which would redound to his own disgrace, but to extort a round sum of money from the Count, by way of composition. Confiding in this protestation, she in a few days gave him intelligence of an assignation she had made with our adventurer, at a certain bagnio near Covent Garden; upon which he secured the assistance of a particular friend and his own journeyman, with whom, and a constable, he repaired to the place of rendezvous, where he waited in an adjoining room, according to the directions of his virtuous spouse, until she made the preconcerted signal of hemming three times aloud, when he and his associates rushed into the chamber and surprised our hero in bed with his inamorata.

The lady on this occasion acted her part to a miracle; she screamed at their approach; and, after an exclamation of "Ruined and undone!" fainted away in the arms of her spouse, who had by this time seized her by the shoulders, and begun to upbraid her with her infidelity and guilt. As for Fathom, his affliction was unutterable, when he found himself discovered in that situation, and made prisoner by the two assistants, who had pinioned him in such a manner, that he could not stir, much less accomplish an escape. All his ingenuity and presence of mind seemed to forsake him in this emergency. The horrors of an English jury overspread his imagination; for he at once perceived that the toil into which he had fallen was laid for the purpose; consequently he took it for granted that there would be no deficiency in point of evidence. Soon as he recollected himself, he begged that no violence might be offered to his person, and entreated the husband to favour him with a conference, in which the affair might be compromised, without prejudice to the reputation of either.
