It is a part of the suggestion that a certain personal _Rapport_ is necessary; so the patient must have this _Rapport_.

This is shown by the fact that when such a patient is hypnotized, the operator _en rapport_ with him can transfer the so-called control to any one else simply by suggesting to the patient that this third party can also hypnotize him.

_Rapport_, therefore, and all the amazing claims of charlatans to powers of charming, stealing another's personality, controlling his will at a distance--all such claims are explained, so far as they have anything to rest upon, by suggestion under conditions of mental hyperaesthesia or exaltation.
I may now add certain practical remarks on the subject.
In general, any method which fixes the attention upon a single stimulus long enough is probably sufficient to produce Hypnosis; but the result is quick and profound in proportion as the patient has the idea that it is going to succeed, i.e., gets the suggestion of sleep.

It may be said, therefore, that the elaborate performances, such as passes, rubbings, mysterious incantations, etc., often resorted to, have no physiological effect whatever, and only serve to work in the way of suggestion upon the mind of the subject.

In view of this it is probable that any person in normal health can be hypnotized, provided he is not too sceptical of the operator's knowledge and power; and, on the contrary, any one can hypnotize another, provided he do not arouse too great scepticism, and is not himself wavering and clumsy.
