I began to fit myself for duty by hammering big nails into a block of wood, and drawing them out again. This was a device of my own, for I wished to give my father another surprise, and did not wish to betray what I was about, by asking his advice as to how I should proceed. I then extracted the teeth from the jaw-bones of all the sheeps-heads that I could lay hands on; after a good deal of practice in this way, I tried to tempt our cook with an offer of five shillings to let me extract a back tooth which had caused her a great deal of suffering at intervals for many months; but she was a timid woman, and would not have allowed me for five guineas, I believe, even to look into her mouth. I also tried to tempt our small stable-boy with a similar sum. He was a plucky little fellow, and, although there was not an unsound tooth in his head, agreed to let me draw one of the smallest of his back teeth for seven and sixpence if it should come out the first pull, and sixpence for every extra rug! I thought the little fellow extravagant in his demands, but, rather than lose the chance, submitted. He sat down quite boldly on our operating chair, but grew pale when I advanced with the instrument; when I tried to open his mouth, he began to whimper, and finally, struggling out of my grasp, fled. I afterwards gave him sixpence, however, for affording me, as I told him, so much pleasurable anticipation.
After this I cast about for another subject, but failed to procure a live one. It occurred to me, however, that I might try my hand on two skeletons that hung in our garret, so I got their heads off without delay, and gradually extracted every tooth in their jaws. As there were about sixty teeth, I think, in each pair, I felt myself much improved before the jaws were toothless. At last, I resolved to take advantage of the first opportunity that should offer, during my fathers absence, to practise on the living subject. It was not long before I had a chance.
