In this experiment request the subject to stand facing you with his eyes open and feet together. Have him look directly into your eyes, or at a small, bright object which you hold a few inches in front of his eyes. Request him to imagine what it would feel like to fall toward you. Stare at him steadily for a few moments and then gradually draw yourself, or the object at which he is gazing, away from him and downward. Do not move too rapidly and stop if you see there is not a tendency on his part to follow.

If you perform this experiment carefully, you will find that in many cases the subject will fall toward you. There is very little likelihood of his going to sleep, and if he does, he can be awakened in the same manner as in the preceding experiment.
