Of Caligula who, however, was scarcely sane, it was said "et quidem stercus uxoris degustavit."[[30]] In Parisian brothels (according to Taxil and others) provision is made for those who are sexually excited by the spectacle of the act of defecation (without reference to contact or odor) by means of a "tabouret de verre," from under the glass floor of which the spectacle of the defecating women may be closely observed. It may be added that the erotic nature of such a spectacle is referred to in the Marquis de Sade's novels.

There is one motive for the existence of coprolagnia which must not be passed over, because it has doubtless frequently served as a mode of transition to what, taken by itself, may well seem the least æsthetically attractive of erotic symbols. I refer to the tendency of the nates to become a sexual fetich. The nates have in all ages and in all parts of the world been frequently regarded as one of the most æsthetically beautiful parts of the feminine body.[[31]] It is probable that on the basis of this entirely normal attraction more than one form of erotic symbolism is at all events in part supported. Dühren and others have considered that the æsthetic charm of the nates is one of the motives which prompt the desire to inflict flagellation on women. In the same way—certainly in some and probably in many cases—the sexual charm of the nates progressively extends to the anal region, to the act of defecation, and finally to the feces.

In a case of Krafft-Ebing's (Op. cit., p. 183) the subject, when a child of 6, accidentally placed his hand in contact with the nates of the little girl who sat next to him in school, and experienced so great a pleasure in this contact that he frequently repeated it; when he was 10 a nursery governess, to gratify her own desires, placed his finger in her vagina; in adult life he developed urolagnic tendencies.

In a case of Moll's the development of a youthful admiration for the nates in a coprolagnic direction may be clearly traced. In this case a young man, a merchant, in a good position, sought to come in contact with women defecating; and with this object would seek to conceal himself in closets; the excretal odor was pleasurable to him, but was not essential to gratification, and the sight of the nates was also exciting and at the same time not essential to gratification; the act of defecation appears, however, to have been regarded as essential. He never sought to witness prostitutes in this situation; he was only attracted to young, pretty and innocent women. The coprolagnia here, however, had its source in a childish impression of admiration for the nates. When 5 or 6 years old he crawled under the clothes of a servant girl, his face coming in contact with her nates, an impression that remained associated in his mind with pleasure. Three or four years later he used to experience much pleasure when a young girl cousin sat on his face; thus was strengthened an association which developed naturally into coprolagnia. (Moll, Untersuchungen über die Libido Sexualis, bd. i, p. 837.)

It is scarcely necessary to remark that an admiration for the nates, even when reaching a fetichistic degree, by no means necessarily involves, even after many years, any attraction to the excreta. A correspondent for whom the nates have constituted a fetich for many years writes: "I find my craving for women with profuse pelvic or posterior development is growing and I wish to copulate from behind; but I would feel a sickening feeling if any part of my person came in contact with the female anus. It is more pleasing to me to see the nates than the mons, yet I loathe everything associated with the anal region."

Moll has recorded in detail a case of what may be described as "ideal coprolagnia"—that is to say, where the symbolism, though fully developed in imagination, was not carried into real life—which is of great interest because it shows how, in a very intelligent subject, the deviated symbolism may become highly developed and irradiate all the views of life in the same way as the normal impulse. (The subject's desires were also inverted, but from the present point of view the psychological interest of the case is not thereby impaired.) Moll's case was one of symbolism of act, the excreta offering no attraction apart from the process of defecation. In a case which has been communicated to me there was, on the other hand, an olfactory fetichistic attraction to the excreta even in the absence of the person.

In Moll's case, the patient, X., 23 years of age, belongs to a family which he himself describes as nervous. His mother, who is anæmic, has long suffered from almost periodical attacks of excitement, weakness, syncope and palpitation. A brother of the mother died in a lunatic asylum, and several other brothers complain much of their nerves. The mother's sisters are very good-natured, but liable to break out in furious passions; this they inherit from their father. There appears to be no nervous disease on the patient's father's side. X.'s sisters are also healthy.

X. himself is of powerful undersized build and enjoys good health, injured by no excesses. He considers himself nervous. He worked hard at school and was always the first in his class; he adds, however, that this is due less to his own abilities than the laziness of his school-fellows. He is, as he remarks, very religious and prays frequently, but seldom goes to church.

In regard to his psychic characters he says that he has no specially prominent talent, but is much interested in languages, mathematics, physics and philosophy, in fact, in abstract subjects generally. "While I take a lively interest in every kind of intellectual work," he says, "it is only recently that I have been attracted to real life and its requirements. I have never had much skill in physical exercises. For external things until recently I have only had contempt. I have a delicately constituted nature, loving solitude, and only associating with a few select persons. I have a decided taste for fiction, poetry and music; my temperament is idealistic and religious, with strict conceptions of duty and morality, and aspirations towards the good and beautiful. I detest all that is common and coarse, and yet I can think and act in the way you will learn from the following pages."

Regarding his sexual life, X. made the following communication: "During the last two years I have become convinced of the perversion of my sexual instinct. I had often previously thought that in me the impulse was not quite normal, but it is only lately that I have become convinced of my complete perversion. I have never read or heard of any case in which the sexual feelings were of the same kind. Although I can feel a lively inclination towards superior representatives of the female sex, and have twice felt something like love, the sight or the recollection even of a beautiful woman have never caused sexual excitement." In the two exceptional instances mentioned it appears that X. had an inclination to kiss the women in question, but that the thought of coitus had no attraction. "In my voluptuous dreams, connected with the emission of semen, women in seductive situations have never appeared. I have never had any desire to visit a puella publica. The love-stories of my fellow-students seemed very silly, dances and balls were a horror to me, and only on very rare occasions could I be persuaded to go into society. It will be easy to guess the diagnosis in my case: I suffer from the sexual attraction of my own sex, I am a lover of boys.
