Quick perceptive powers will enable a hypnotist to instantly realize the peculiar characteristics of his subjects and to notice the effect his efforts are having upon them. All subjects cannot be hypnotized by the same methods. Some yield readily to mysterious words and movements; others are impressed best by music or monotonous sounds; others require passes or manipulations; and, again, in some cases, fear of the operator must be aroused. while in others their complete confidence must be obtained.

The study of human nature becomes very important in connection with hypnotism, and the habit of quickly observing minute details should be cultivated. In choosing subjects it is valuable and in controlling them while under hypnotic influence it may save much trouble and annoyance.

Self-Possession is always very desirable. A person who "loses his head" will make a poor hypnotist. Occasions are constantly arising where the self-possession of the operator is of the utmost importance. For example, a subject may not awaken at once when commanded to do so, which will require either some other suggestion quickly made or the adoption of another method of awakening. If there should be the least hesitation or loss of self-control, those witnessing the performance would be quickly thrown into a state of consternation. Again, it frequently happens that a new subject will not readily yield and will manifest the most stubborn resistance to all efforts to hypnotize him. The operator must not then lose his self-possession and pronounce the attempt a failure or abandon it without suitable comment, such as, "Well, that was pretty well done; you're a difficult subject; but you can be hypnotized;" or, "I will hypnotize you when the conditions are more favorable; there is something disturbing you and we'll have to find out what it is." Never should the least discomfiture be manifested.

It detracts from the operator's power and self-confidence; it weakens the susceptibility of his subjects and causes spectators to lose confidence in his ability.
