CHAPTER II.
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.
