Alma Z. was an unusually healthy and intellectual girl, a strong and attractive character, a leading spirit in whatever she undertook, whether in study, sport, or society. From overwork in school, and overtaxed strength in a case of sickness at home, her health was completely broken down, and after two years of great suffering suddenly a second personality appeared. In a peculiar child-like and Indian-like dialect she announced herself as "Twoey," and that she had come to help "Number One" in her suffering. The condition of "Number One" was at this time most deplorable; there was great pain, extreme debility, frequent attacks of syncope, insomnia, and a mercurial stomatitis which had been kept up for months by way of medical treatment and which rendered it nearly impossible to take nourishment in any form. "Twoey" was vivacious and cheerful, full of quaint and witty talk, never lost consciousness, and could take abundant nourishment, which she declared she must do for the sake of "Number One." Her talk was most quaint and fascinating, but without a trace of the acquired knowledge of the primary personality. She gave frequent evidence of supranormal intelligence regarding events transpiring in the neighbourhood. It was at this time that the case came under my observation, and has remained so for the past ten years. Four years later, under depressing circumstances, a third personality made its appearance and announced itself as "The Boy." This personality was entirely distinct and different from either of the others. It remained the chief alternating personality for four years, when "Twoey" again returned.
All these personalities, though absolutely different and characteristic, were delightful each in its own way, and "Twoey" especially was, and still is, the delight of the friends who are permitted to know her, whenever she makes her appearance; and this is always at times of unusual fatigue, mental excitement, or prostration; then she comes and remains days at a time. The original self retains her superiority when she is present, and the others are always perfectly devoted to her interest and comfort. "Number One" has no personal knowledge of either of the other personalities, but she knows them well, and especially "Twoey," from the report of others and from characteristic letters which are often received from her; and "Number One" greatly enjoys the spicy, witty, and often useful messages which come to her through these letters and the report of friends.
Dr. Mason goes on to say:—
Here are three cases [the one just given, that of another patient of his own, and that of Félida X.] in which a second personality—perfectly sane, thoroughly practical, and perfectly in touch and harmony with its surroundings—came to the surface, so to speak, and assumed absolute control of the physical organisation for long periods of time together. During the stay of the second personality the primary or original self was entirely blotted out, and the time so occupied was a blank. In neither of the cases described had the primary self any knowledge of the second personality, except from the report of others or letters from the second self, left where they could be found on the return of the primary self to consciousness. The second personality, on the other hand, in each case, knew of the primary self, but only as another person—never as forming a part of, or in any way belonging to their own personalities. In the case of both Félida X. and Alma Z., there was always immediate and marked improvement in the physical condition when the second personality made its appearance.
The case of Mollie Fancher,[24] which, had it been observed and recorded with scientific accuracy, might have been one of the most instructive of all, seems to stand midway between the transformations of Louis Vivé—each of them frankly himself at a different epoch of life—and the "pseudo-possessions" of imaginary spirits with which we shall in a later chapter have to deal.
The case of Anna Winsor[25] goes so far further in its suggestion of interference from without that it presents to us, at any rate, a contrast and even conflict between positive insanity on the part of the organism generally with wise and watchful sanity on the part of a single limb, with which that organism professes to have no longer any concern.
The last case[26] that I shall mention is that of Miss Mary Lurancy Vennum, the "Watseka Wonder."
The case briefly is one of alleged "possession," or "spirit-control." The subject of the account, a girl nearly fourteen years old, living at Watseka, Illinois, became apparently controlled by the spirit of Mary Roff, a neighbour's daughter, who had died at the age of eighteen years and nine months, when Lurancy Vennum was a child of about fifteen months old. The most extraordinary feature in the case was that the control by Mary Roff lasted almost continuously for a period of four months.
For the present we must consider this case as a duplication of personality—a pseudo-possession, if you will—determined in a hysterical child by the suggestion of friends, but at a later stage, and when some other wonders have become more familiar than now, we may find that this singular narrative has further lessons to teach us.
We have now briefly surveyed a series of disintegrations of personality ranging from the most trifling idée fixe to actual alternations or permanent changes of the whole type of character. All these form a kind of continuous series, and illustrate the structure of the personality in concordant ways. There do exist, it must be added, other forms of modified personality with which I shall not at present deal. Those are cases where some telepathic influence from outside has been at work, so that there is not merely dissociation of existing elements, but apparent introduction of a novel element. Such cases also pass through a long series, from small phenomena of motor automatism up to trance and so-called possession. But all this group I mention here merely in order to defer their discussion to later chapters.
