as hypnotised, and showed that
he remembered perfectly all that happened to him between these two
dates. The confusion of his two memories in his earlier life is
puzzling, but it in no way impairs the value of this illustration of the
existence of two independent memories--two selfs, so to speak, within a
single skin.

The phenomenon is not uncommon, especially with epileptic patients.
Every mad-doctor knows cases in which there are what may be described as
alternating consciousnesses with alternating memories. But the
experiments of the French hypnotists carry us much further. In their
hands this Sub-conscious Personality is capable of development, of
tuition, and of emancipation. In this little suspected region lies a
great resource. For when the Conscious Personality is hopeless,
diseased, or demoralised the Unconscious Personality can be employed to
renovate and restore the patient, and then when its work is done it can
become unconscious once more and practically cease to exist.

Louis V. and His Two Souls.

There is at present[2] a patient in France whose case is so
extraordinary that I cannot do better than transcribe the report of it
here, especially because it tends to show not only that we have two
personalities, but that each may use by preference a separate lobe of
the brain. The Conscious Personality occupies the left and controls the
right hand, the Unconscious the right side of the head and controls the
left hand. It also brings to light a very curious, not to say appalling,
fact, viz., the immense moral difference there may be between the
Conscious and the Unconscious Personalities. In the American case Bourne
was a character practically identical with Brown. In this French case
the character of each self is entirely different. What makes the case
still more interesting is that, besides the two personalities which we
all seem to possess, this patient had an arrested personality, which was
only fourteen years old when the age of his body was over forty. Here is
the report, however, make of it what you will.

[2] 1891.

"Louis V. began life (in 1863) as the neglected child of a turbulent
mother. He was sent to a reformatory at ten years of age, and there
showed himself, as he has always done when his organization had given
him a chance, quiet, well-behaved, and obedient. Then at fourteen years
old he had a great fright from a viper--a fright which threw him off his
