M.Janet began by the following simple command: "When I clap my hands you will write Bonjour." This was done in the usual scrawling script of automatism, and Lucie, though fully awake, was not aware that she had written anything at all.
M.Janet simply ordered the entranced girl to write answers to all questions of his after her waking.

The command thus given had a persistent effect, and while the awakened Lucie continued to chatter as usual with other persons, her Unconscious Self wrote brief and scrawling responses to M.Janet's questions.

This was the moment at which, in many cases, a new and invading separate personality is assumed.
A singular conversation gave to this limited creation, this statutory intelligence, an identity sufficient for practical convenience.

"Do you hear me ?" asked Professor Janet.

Answer (by writing), "No." "But in order to answer one must hear." "Certainly." "Then how do you manage ?" "I don't know." "There must be somebody that hears me." "Yes." "Who is it ?" "Not Lucie." "Oh, some one else?
Shall we call her Blanche ?" "Yes, Blanche." Blanche, however, had to be changed.
