Bone-setter is due to the eminent naturalist for his testimony of the value of, and his vindication of, the art they practise. His own quoted case is a peculiar one, but the experience of every Bone-setter could furnish a parallel and even more surprising instances of cures effected when the resources of scientific surgery have failed. Of the older Bone-setters we find some extraordinary accounts, and evidently not penned by friendly hands. One of the most famous of the Bone-setters of the last century was Mrs. Mapp, of Epsom, who was the daughter of a Bone-setter named Wallin, of Hindon, Wiltshire. The accounts of her life and career, which have come down to us, are very contradictory. For instance, the _London Magazine_ tells us that in August, 1736, the town was surprised with the fame of a young woman at Epsom, who, though not very regular in her conduct (so it was said) wrought such cures that seem miraculous in the Bone-setting way. The concourse of people to Epsom on this occasion is incredible, and it is reckoned she gets nearly 20 guineas a day, she executing what she does in a very quick manner. She has strength enough to put in any man’s shoulder without any assistance; and thus her strength makes the following story the more probable. A man came to her, sent, as is supposed by some surgeons, on purpose to try her skill, with his hand bound up, and pretended his wrist was put out, which upon examination she found to be false; but, to be even with him in his imposition, she gave it a wrench which really put it out, and bade him _go to the fools who sent him and get it set again_, or, if he would come to her that day month, she would do it herself. It is further stated that since she became famous she married one Mr. Hill Mapp, late servant to a mercer on Ludgatehill who, it is said, soon left her and carried off £100 of her money. Her professional success, however, says another account, must have gone far to solace her for matrimonial failure. Besides driving a profitable trade at home, she used to drive to town once a week in a coach-and-four, and return again bearing away the crutches of her patients as trophies of honour. She held her levees at the “Grecian” Coffee House, where she operated successfully upon a niece of Sir Hans Sloane. The same day she straightened the body of a man whose back had stuck out two inches for nine years; and a gentleman who went into the house with one shoe-heel six inches high came out again cured of a lameness of twenty years standing, and with both his legs of equal length. It does not appear that she was always so successful, for one Thomas Barber, tallow-chandler, of Saffron-hill, thought proper to publish a warning to her would-be patients. The cure of Sir Hans Sloane’s niece made Mrs. Mapp town talk, and, if it was only known that she intended to make one of the audience, the theatre favoured with her presence, was crowded to excess.
