Two cases are covered by Dr. Myers. The first case is of Louis V. He suffered from epilepsy, hysteria and paralysis after a great fright from a viper. His memory would occasionally relapse back to a previous time period. Later in life he would oscillate back and forth between two personalities. Each personality seemed to be controlled by a different side of the brain. The second case is that of Felidia X. She suffered from the presence of a second personality. She was able to function in both of these states due to being put into a hypnotic trance. Dr. Myers compares the two cases on the grounds of morals vs. biology.
The multiple personality case of Blanche Witt is discussed. One of her personalities suffered from blindness in one eye, the other personality had perfect vision. Her condition was treated with hypnotism. The case of Marceline R. is also discussed. She suffered from an eating disorder, but when hypnotized she was able to eat properly, but returned to her former state when not hypnotized. Neither woman was cured, but was able to be symptom free while hypnotized.
