The kind of soil on which the germs of erotic symbolism may develop is well seen in cases of sexual hyperæsthesia. In such cases all the emotionally sexual analogies and resemblances, which in erotic symbolism are fixed and organized, may be traced in vague and passing forms, a single hyperæsthetic individual perhaps presenting a great variety of germinal symbolisms.

Thus it has been recorded of an Italian nun (whose sister became a prostitute) that from the age of 8 she had desire for coitus, from the age of 10 masturbated, and later had homosexual feelings, that the same feelings and practices continued after she had taken the veil, though from time to time they assumed religious equivalents. The mere contact, indeed, of a priest's hand, the news of the presentation of an ecclesiastic she had known to a bishopric, the sight of an ape, the contemplation of the crucified Christ, the figure of a toy, the picture of a demon, the act of defecation in the children entrusted to her care (whom, on this account, and against the regulations, she would accompany to the closets), especially the sight and the mere recollection of flies in sexual connection—all these things sufficed to produce in her a powerful orgasm. (Archivio di Psichiatria, 1902, fasc. II-III, p. 338.)

A boy of 15 (given to masturbation), studied by Macdonald in America, was similarly hyperæsthetic to the symbols of sexual emotion. "I like amusing myself with my comrades," he told Macdonald, "rolling ourselves into a ball, which gives one a funny kind of warmth. I have a special pleasure in talking about some things. It is the same when the governess kisses me on saying good night or when I lean against her breast. I have that sensation, too, when I see some of the pictures in the comic papers, but only in those representing a woman, as when a young man skating trips up a girl so that her clothes are raised a little. When I read how a man saved a young girl from drowning, so that they swam together, I had the same sensation. Looking at the statues of women in the museum produces the same effect, or when I see naked babies, or when a mother suckles a child. I have often had that sensation when reading novels I ought not to read, or when looking at a new-born calf, or seeing dogs and cows and horses mounting on each other. When I see a girl flirting with a boy, or leaning on his shoulder or with his arm round her waist, I have an erection. It is the same when I see women and little girls in bathing costume, or when boys talk of what their fathers and mothers do together. In the Natural History Museum I often see things which give me that sensation. One day when I read how a man killed a young girl and carried her into a wood and undressed her I had a feeling of enjoyment. When I read of men who were bastards the idea of a woman having a child in that way gives me this sensation. Some dances, and seeing young girls astride a horse, excited me, too, and so in a circus when a woman was shot out of a cannon and her skirts flew in the air. It has no effect on me when I see men naked. Sometimes I enjoy seeing women's underclothes in a shop, or when I see a lady or a girl buying them, especially if they are drawers. When I saw a lady in a dress which buttoned from top to bottom it had more effect on me than seeing underclothes. Seeing dogs coupling gives me more pleasure than looking at pretty women, but less than looking at pretty little girls." In order of increasing intensity he placed the phenomena that affected him thus: The coupling of flies, then of horses, then the sight of women's undergarments, then a boy and a girl flirting, then cows mounting on each other, the statues of women with naked breasts, then contact with the governess's body and breasts, finally coitus. (Arthur Macdonald, Le Criminel-Type, pp. 126 et seq.)

It is worthy of remark that the instinct of nutrition, when restrained, may exhibit something of an analogous symbolism, though in a minor degree, to that of sex. The ways in which a hyperæsthetic hunger may seek its symbols are illustrated in the case of a young woman called Nadia, who during several years was carefully studied by Janet. It is a case of obsession ("maladie du scrupule"), simulating hysterical anorexia, in which the patient, for fear of getting fat, reduced her nourishment to the smallest possible amount. "Nadia is generally hungry, even very hungry. One can tell this by her actions; from time to time she forgets herself to such an extent as to devour greedily anything she can put her hands on. At other times, when she cannot resist the desire to eat, she secretly takes a biscuit. She feels horrible remorse for the action, but, all the same, she does it again. Her confidences are very curious. She recognizes that a great effort is needed to avoid eating, and considers she is a heroine to resist so long. 'Sometimes I spent whole hours in thinking about food, I was so hungry; I swallowed my saliva, I bit my handkerchief, I rolled on the floor, I wanted to eat so badly. I would look in books for descriptions of meals and feasts, and tried to deceive my hunger by imagining that I was sharing all these good things,'" (P. Janet, "La Maladie du Scrupule," Revue Philosophique, May, 1901, p. 502.) The deviations of the instinct of nutrition are, however, confined within narrow limits, and, in the nature of things, hunger, unlike sexual desire, cannot easily accept a fetich.
