The following, from a Philadelphia journal, gives a striking illustration of the fact that the imagination is a _real_ factor in many cases of physical ailment: "The fact that the throes of the imagination under great nervous excitement often produce a corresponding physical frenzy was illustrated recently in the case of a man who had gone to sleep with his artificial teeth in his mouth. Waking suddenly with a choking sensation, he found his teeth had disappeared. He looked in the glass of water where they were usually deposited, did not see them and realized they must be far down his throat. Choking and struggling, he hammered on the door of a friend sleeping in the house, who, seeing his critical condition, vainly tried to draw the teeth out of the sufferer's throat. He could feel the teeth, but had not the strength to extract them. He ran for a blacksmith who lived a few doors away, but the blacksmith's hand was too big to put into the man's mouth. A doctor had been sent for, but he was so long in coming that the victim of the accident seemed likely to die of suffocation before the physician arrived. A little girl of ten years was brought under the impression that her small hand might reach the obstacle and withdraw it, but she got frightened and began to cry. The sufferer became black in the face, his throat swelled out, and his friends expected every moment to be his last, when finally the doctor arrived. He heard the history of the case, saw that the teeth were not in the man's jaws nor in their nightly receptacle, felt the throat and cast his eyes seriously upon the floor. _There, on the floor, he saw the whole set of teeth._ He adjusted them to the jaws of the patient, told him to breathe freely, and every symptom of suffocation disappeared."
