, just after
passing into the second stage, she attended the funeral of an
acquaintance. Returning in a cab she felt the period coming on which
she calls her crisis (normal state). She dozed several seconds, without
attracting the attention of the ladies who were in the cab, and awoke
in the other state, absolutely at a loss to know why she was in a
mourning carriage with people who, according to custom, were praising
the qualities of a deceased person whose name she did not even know.
Accustomed to such positions, she waited; by adroit questions she
managed to understand the situation, and no one suspected what had
happened. Once when in her abnormal condition she discovered that her
husband had a mistress, and was so overcome that she sought to commit
suicide. Yet in her normal mind she meets the woman with perfect
equilibrium and forgetfulness of any cause for quarrel. It is only in
her abnormal state that the jealousy recurs. As the years went on the
second state became her usual condition. That which was at first
accidental and abnormal now constitutes the regular center of her
psychic life. It is rather satisfactory to chronicle that as between
the two egos which alternately possess her, the more cheerful has
finally reached the ascendant."

Jackson reports the history of the case of a young dry-goods clerk who
was seized with convulsions of a violent nature during which he became
unconscious. In the course of twenty-four hours his convulsions abated,
and about the third day he imagined himself in New York paying court to
a lady, and having a rival for her favors; an imaginary quarrel and
duel ensued. For a half-hour on each of three days he would start
exactly where he had left off on the previous day. His eyes were open
and to all appearances he was awake during this peculiar delirium. When
asked what he had been doing he would assert that he had been asleep.
His language assumed a refinement above his ordinary discourse. In
proportion as his nervous system became composed, and his strength
improved, this unnatural manifestation of consciousness disappeared,
and he ultimately regained his health.

A further example of this psychologic phenomenon was furnished quite
meetly at a meeting of the Clinical Society of London, where a well
known physician exhibited a girl of twelve, belonging to a family of
good standing, who displayed in the most complete and indubitable form
this condition of dual existence. A desc
