which, were it better understood, might perhaps serve to explain certain
cases of insanity. Mme. B., during her somnambulism (_i.e._ Leonie
II.) had had a sort of hysterical crisis; she was restless and noisy and
I could not quiet her. Suddenly she stopped and said to me with terror.
'Oh, who is talking to me like that? It frightens me.' 'No one is
talking to you.' 'Yes! there on the left!' And she got up and tried to
open a wardrobe on her left hand, to see if some one was hidden there.
'What is that you hear?' I asked. 'I hear on the left a voice which
repeats, "Enough, enough, be quiet, you are a nuisance."' Assuredly the
voice which thus spoke was a reasonable one, for Leonie II. was
insupportable; but I had suggested nothing of the kind, and had no idea
of inspiring a hallucination of hearing. Another day Leonie II. was
quite calm, but obstinately refused to answer a question which I asked.
Again she heard with terror the same voice to the left, saying, 'Come,
be sensible, you must answer.' Thus the Unconscious sometimes gave her
excellent advice."

And in effect, as soon as Leonie III. was summoned into communication,
she accepted the responsibility of this counsel. "What was it that
happened?" asked M. Janet, "when Leonie II. was so frightened?" "Oh!
nothing. It was I who told her to keep quiet; I saw she was annoying
you; I don't know why she was so frightened."

Note the significance of this incident. Here we have got at the root of
a hallucination. We have not merely inferential but direct evidence that
the imaginary voice which terrified Leonie II. proceeded from a
profounder stratum of consciousness in the same individual. In what way,
by the aid of what nervous mechanism, was the startling monition
conveyed?

Just as Mme. B. was sent, by means of passes, into a state of lethargy,
from which she emerged as Leonie II., so Leonie II., in her turn, was
reduced by renewed passes to a state of lethargy from which she emerged
no longer as Leonie II. but as Leonie III. This second waking is slow
and gradual, but the personality which emerges is, in one important
point, superior to either Leonie I. or Leonie II. Although one among the
subject's phases, this phase possesses the memory of every phase. Leonie
III., like Leonie II., knows the normal life of Leonie I., but
distinguishes herself from Leonie I., in whom, it must be said, these
subjacent personalities appear to take little interest. But Leonie III.
