B. has been so often hypnotised, and during so many years (for
she was hypnotised by other physicians as long ago as 1860), that Leonie
II. has by this time acquired a considerable stock of memories which
Madame B. does not share. Leonie II., therefore, counts as properly
belonging to her own history and not to Madame B.'s all the events which
have taken place while Madame B.'s normal self was hypnotised into
unconsciousness. It was not always easy at first to understand this
partition of past experiences.

"Madame B. in the normal state," says Professor Janet, "has a husband
and children. Leonie II., speaking in the somnambulistic trance,
attributes the husband to the 'other' (Madame B.), but attributes the
children to herself.... At last I learnt that her former mesmerisers, as
bold in their practice as certain hypnotisers of to-day, had induced
somnambulism at the time of her accouchements. Leonie II., therefore,
was quite right in attributing the children to herself; the rule of
partition was unbroken, and the somnambulism was characterised by a
duplication of the subject's existence" (p. 391).

Still more extraordinary are Leonie II.'s attempts to make use of Leonie
I.'s limbs without her knowledge or against her will. She will write
postscripts to Leonie I.'s letters, of the nature of which poor Leonie
I. is unconscious.

It seems, however, that when once set up this new personality can
occasionally assume the initiative, and can say what it wants to say
without any prompting. This is curiously illustrated by what may be
termed a conjoint epistle addressed to Professor Janet by Madame B. and
her secondary self, Leonie II. "She had," he says, "left Havre more than
two months when I received from her a very curious letter. On the first
page was a short note written in a serious and respectful style. She was
unwell, she said--worse on some days than on others--and she signed her
true name, Madame B. But over the page began another letter in quite a
different style, and which I may quote as a curiosity:--'My dear good
sir,--I must tell you that B. really makes me suffer very much; she
cannot sleep, she spits blood, she hurts me. I am going to demolish her,
she bores me. I am ill also. This is from your devoted Leontine' (the
name first given to Leonie II).

"When Madame B. returned to Havre I naturally questioned her concerning
this curious missive. She remembered the first letter very distinctly,
but she had not
