Cases of so-called double consciousness or multiple personality are
rather numerous in medical and psychologic literature and are generally of
a common type—the individual possesses or is subject to two conditions
of consciousness, in either or both of which he or she is unconscious or amnesic
of his doings in the other. Such conditions are not at all infrequent in epileptics
and often afford opportunities for interesting studies and speculations. It
is not often, however, that we have a well reported observation of multiple
personalities, co-existing as it were simultaneously in the subject from their
first appearance to their final exit from the scene. What appears to be such
a case forms the subject of a recent article by Dr. Morton Prince,1
whose reputation as a physician and neurologist gives it the credibility that
might otherwise be questioned.
