The room in which we were was the operating one of the office, where patients were examined, and surgical operations performed. It was furnished with all the usual appliances of such an establishment. In the middle of the room, securely fastened to the floor by screws, was a large arm-chair, with head-board and straps, to confine the body and limbs of the patient whilst the operator was at work, in such cases as required it. On either side of the house, driven into the wall, were a couple of iron bolts, to which were fastened blocks and pulleys, used when reducing old dislocations, when all milder means had failed. The chair, pulleys, and a small hand-vice were the apparatus intended to be used by me in the extraction of the Kentuckian's tooth, by the “Mississippi patent plan.” The patient watched all our preparations--for I quickly let the other students into the plan of the intended joke--with great interest, and seemed hugely tickled at the idea of having his tooth pulled without pain “for a quarter,” and a dose of castor-oil extra. Everything being ready, we invited the subject to take his seat in the operating chair, telling him it was necessary, agreeably to our mode of pulling teeth, that the body and arms should be perfectly quiet; that other doctors, who hadn't bought the right to use the 'patent plan,' used the pullikins, whilst I operated with the pulleys. I soon had him immoveably strapped to the chair, hand and foot. Introducing the hand-vice in his mouth, which, fortunately for me, was a large one, I screwed it fast to the offending tooth, then connecting it with the first cord of the pulleys and intrusting it to the hands of two experienced assistants, I was ready to commence the extraction. Giving the word, and singing, “Lord, receive this sinner's soul,” we pulled slowly, so as to let the full strain come on the neck bones gradually. Though I live till every hair on my head is as hollow as a dry skull, I shall never forget the scene. Clothed in homespun of the copperas hue, impotent to help himself, his body immoveably fixed to the chair, his neck gradually extending itself, like a terrapin's emerging from its shell, his eyes twice their natural size, and projected nearly out of their sockets, his mouth widely distended, with the vice hidden in its cavity, and the connexion of the rope being behind his cheeks, giving the appearance as if we had cast anchor in his stomach, and were heaving it slowly home, sat the Kentuckian, screaming and cursing that we were pulling his head off without moving the tooth, and that the torment was awful. But I coolly told him 'twas the usual way the 'Mississippi patent plan' worked, and directed my assistants to keep up their steady pull.
