difficult to produce under hypnosis. The phlegmatic person
may become choleric, the reserved person become flippant and
rude, the irreligious become pious, etc. Commonly, if the
hypnotic sleep has been deep, there is, upon awakening, little
or no memory of what has occurred during the trance. But
all the facts can usually be recalled during a subsequent
hypnotisation. A curious phenomenon is that of post-hyp-
notic suggestion. A person told to perform some action after
awakening may have no recollection of the injunction upon
arousing from the hypnotic slumber, but with few exceptions
he will at the time designated faithfully execute the act.
Facts of this kind have led to a good deal of need-
less alarm as to the dangers of hypnotism. In point of fact
it is practically impossible to force a person to do anything
seriously offensive to his moral or æsthetic sense of the right
and the decent. Moreover, persons of normal make-up can
not be hypnotised against their wills -- at all events not until
the process has been performed so often as to become more or
less habitual. A thing much more to be feared in our day
is the auto-suggestion of a hypnotic character by virtue of
which mobs and great crowds give way to the wildest and
most beastly excesses, as often occurs in lynchings. Although
hypnotism undoubtedly has therapeutic value, it should not
be indiscriminately cultivated by untrained persons. The
same statement holds true only in less degree of "suggestion"
used as a medical method without actual hypnotising. Of
its value there can be no question, for it has been demonstrated
repeatedly from the dawn of time to the present day, and every
successful general practitioner inevitably makes more or less
use of it. But it must be intelligently employed, otherwise
it may prove harmful.

C. Dreams and Sleep. -- Dreams afford a familiar instance
of disturbed personality. Sometimes this is manifested sim-
ply in the ridiculous judgments which we pass upon dream
situations, and the absurd sentiments which they call forth.
