2d. In September, 1836, I was called by a physician to see his wife. He said she was suffering terribly from facial neuralgia, and thought it was caused by a tooth. She was in her eighth month of pregnancy. He had applied the usual remedies, which gave no relief. I examined her teeth; found both the third-molars on upper jaw decayed, and on slightly tapping them with the handle of an instrument, the pain was greatly increased. He said he was afraid of the consequences, in her state, of having the teeth extracted. I told him nothing else would give relief. She said take them out, it cannot be worse than I am now suffering. I parted the gums from the teeth with a lance; I had barely completed this part of the operation when she fainted; her mouth was open; I took my forceps and extracted both teeth; brought her head forward to prevent the blood running down her throat; we soon brought her back to consciousness, and the first thing she said was: "I cannot have them out." Her husband said: "Darling, they are both out." She said, "Are they? I did not feel it; I am so glad; the pain is all gone." The Doctor said to me--"You are a bold man: I would have stopped you if I could, but you was too quick for me." I afterwards learned that no serious result followed the operation. 3d. In August, 1856, a young lady, aged about twenty, came to my office at eight o'clock A. M. Temperament nervous, lymphatic. Said she had not slept a wink all night. Her face was pale, hands cold, pulse feeble. Said she had a mortal dread of having a tooth extracted. I put my mouth-mirror into her mouth for examination, and saw the tooth caused the trouble. In an instant she fainted. I took my forceps and extracted the tooth, used restoratives and soon brought her to. The first thing she said was--"I cannot have it out." I showed her the tooth. She said: "Oh! I am so glad I did not feel it;" and left the office laughing about it. 4th. In the Fall of 1858 a lady called to have the two upper front incisors filled. She appeared to be middle-aged, and apparently in good health. On examination, the teeth were very close together--not badly decayed, but must be separated for sufficient room to enable me to do the work properly. Our only means, then, was either wedging or filing them. I filed about one quarter of what was necessary, and she fainted. I then filed as rapidly as possible while she was unconscious, and completed this part of the operation, and used restoratives, and soon brought her to. I gave her a glass of wine, and completed the operation without further trouble.
