he mental states of those who experiment with him.

4. So-called _Rapport_. This term covers all the facts known, before
the subject was scientifically investigated, by such expressions as
"personal magnetism," "will power over the subject", etc. It is true
that one particular operator alone may be able to hypnotize a
particular patient; and in this case the patient is, when hypnotized,
open to suggestions from that person only. He is deaf and blind to
everything enjoined by anyone else. It is easy to see from what has
already been said that this does not involve any occult nerve
influence or mental power. A sensitive patient anybody can hypnotize,
provided only that the patient have the idea or conviction that the
experimenter possesses such power. Now, let a patient get the idea
that only one man can hypnotize him, and that is the beginning of the
hypnotic suggestion itself. 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. It is probable, however, that
suscept
