The most remarkable woman doctor made mention of in English literature, was Mrs. Mapp, _née_ Sally Wallin. We have collected these facts respecting her origin, character, and career, from _Chambers' Miscellany_ and the _Gentlemen's Magazine_, 1736-7. Hogarth has immortalized her in his "Undertaker's arms." She is placed at the top of that picture, between Josh Ward, the _Pill_ doctor, and Chevalier Taylor, the quack oculist. (See page 668.) She was born in Weltshire, in 169-. Her father was a "bone-setter," which occupation "run in the family," like that of the Sweets, of Connecticut, or like the marine whom Mrs. Mapp saw one day, as she, in her carriage, was driving "along the Strand, O." Said sailor having a wooden leg, the doctress asked, "How does it happen, fellow, that you've a wooden leg." "O, easy enough, madam; my father had one before me. It sort o' runs in the family, marm," was the laconic reply. From a barefooted school-girl at Weltshire, where Sally obtained barely the rudiments of a common education, she became her father's assistant in bone-setting and manipulating. The next we hear of Miss Wallin, is at Epsom, where she became known as "Crazy Sally." She has been described as a "very coarse, large, vulgar, illiterate, drunken, bawling woman," "known as a haunter of fairs, about which she loved to reel, screaming and abusive, in a state of roaring intoxication." It is astonishing as true, that this unattractive specimen of the female sex became so esteemed in Epsom, where she set up as a physician, that the town offered her £100 to remain there a year! The newspapers sounded her praise, the gentry, even, lauded her skill, and physicians witnessed her operations. "Crazy Sally" awoke one morning and found herself famous. Patients of rank and wealth flocked from every quarter. Attracted by her success and her accumulating wealth, rather than by her _beauty_ or _amiable_ disposition, an Epsom swain made her an offer of marriage, which she, like a woman, accepted. This fellow's name was Mapp, who lived with her but for a fortnight, during which time he "thrashed her" (or she him, it is not just clear which) "three times," and appropriating all of her spare change, amounting to five hundred dollars, he took to himself one half of the world, and quietly left her the other. Our informant adds, "She found consolation for her wounded affections in the homage of the world. She became a notoriety of the first water; every day the public journals gave some interesting account of her, and her remarkable operations."
