4. _Paræsthesia_, (perversion of the sexual instinct, _i.e._,

excitability of the sexual functions to inadequate stimuli). These cerebral anomalies fall within the domain of psychopathology. The spinal and peripheral anomalies may occur in combination with them, but these affect persons, as a rule, that are free from mental disease. They may occur in various combinations, and become the cause of sexual crimes. For this reason, they demand consideration in the following description. However, the cerebral anomalies claim the principal interest, since they very frequently lead to the commission of perverse and even criminal acts. A. PARADOXIA. SEXUAL INSTINCT MANIFESTING ITSELF INDEPENDENTLY OF PHYSIOLOGICAL PROCESSES. _1. Sexual Instinct Manifested in Childhood._ Every physician conversant with nervous affections and diseases incident to childhood is aware of the fact that manifestation of sexual instinct may occur in very young children. The observations of Ultzmann concerning masturbation in childhood[31] are worthy of attention in relation to it. It is necessary here to differentiate between the numerous cases where, as a result of phimosis, balanitis, or oxyuris in rectum or vagina, young children have itching of the genitals, and experience a kind of pleasurable sensation from manipulations thus induced, and thus come to practice masturbation; and those cases in which sexual ideas and impulses occur in the child as a result of cerebral processes without peripheral causes. It is only in this latter class of cases that we have to do with the early manifestation of sexual instinct. In such cases it may always be regarded as an accompanying symptom of a neuro-psychopathic constitutional condition. A case of Marc’s (“Die Geisteskrankheiten,” etc., von Ideler, i, p. 66) illustrates very well these conditions. The subject was a girl of eight years, of respectable family, who was devoid of all child-like and moral feelings, and had masturbated from her fourth year; at the same time she consorted with boys of the age of ten or twelve. She had thought of killing her parents, that she might become her own mistress and give herself up to pleasure with men. In these cases of early manifestation of libido the children come also to masturbate; and, since they are greatly predisposed constitutionally, they frequently sink into dementia, or become subjects of severe degenerative neuroses or psychoses. Lombroso (_Archiv di Psichiatria_, iv, p. 22) has collected a number of cases of children affected with very decided hereditary taint, which belong in this category. One was that of a girl who masturbated shamelessly and almost constantly at the age of three. Another girl began at the age of eight, and continued to practice masturbation when married, and even during pregnancy. She was pregnant twelve times. Five of the children died early, four were hydrocephalic, and two boys began to masturbate,—one at the age of seven, the other at the age of four. Zambaco (_L’Encéphale_, 1882, Nr. 1, 2) tells the disgusting story of two sisters affected with premature and perverse sexual desire. The elder, R., masturbated at the age of seven, practiced lewdness with boys, stole wherever she could, seduced her four-year-old sister into masturbation, and at the age of ten was given up to the practice of the most revolting vices. Even _ferrum candens ad clitoridem_ had no effect in overcoming the practice, and she masturbated with the cassock of a priest while he was exhorting her to reformation. _2. Re-awakening of Sexual Instinct in Old Age._[32] There are infrequent cases in which the sexual instinct persists until a great age. “Senectus non quidem annis sed viribus magis æstimatur” (Zittmann). Oesterlen (Maschka, Handb., iii, p. 18) mentions the case of a man aged 83, who was sentenced to three years’ imprisonment by a Wurtemberg court on account of sexual misdemeanors. Unfortunately nothing is said of the nature of the crime or of the mental condition of the criminal.[33] The manifestation of sexual instinct in old age is not in itself pathological; but presumption of pathological conditions must necessarily be entertained when the individual is decrepit and his sexual life has already long become extinct; and when the impulse, in a man whose sexual needs were in his early life, perhaps, not very marked, manifests itself with greater strength, and strives for even perverse satisfaction in a shameless and impulsive manner. In such cases there is at once suggested a presumption of pathological conditions. Medical science recognizes the fact that such an impulse depends upon the morbid alterations of the brain which lead to senile dementia. This abnormal manifestation of sexual life may be the precursor of senile dementia, and make its appearance even long before there are any well-defined manifestations of intellectual weakness. The attentive and experienced observer will always be able to detect in this prodromal stage an alteration of character _in pejus_, and a deterioration of the moral sense accompanying the peculiar sexual manifestation. The libido of those passing into senile dementia is at first expressed in lascivious speech and gesture. The next objects of the attempts of these senile subjects of brain atrophy and psychical degeneration are children. This sad and dangerous fact is explained by the better opportunity they have of falling in with children, but more especially by a feeling of imperfect sexual power. Defective sexual power and greatly diminished moral sense explain the additional fact of the perversity of the sexual acts of these aged men. They are the equivalents of the impossible physiological act. The annals of legal medicine distinguish, as such, exhibition of the genitals,[34] lustful handling of the genitals of children,[35] inducing them to perform manustupration of the seducer, and performing masturbation[36] or flagellation on the victim. In this stage the intellect may still be sufficiently intact to allow avoidance of publicity and discovery, while the moral sense is too far gone to allow consideration of the moral significance of the act and resistance to the impulse. With the progress of dementia, these acts are more and more shamelessly committed. Then care on account of defective sexual power disappears, and adults also become the objects of the senile passion; but the defective sexual power necessitates equivalents for coitus. Not infrequently sodomy results, and, as Tarnowsky (_op. cit._, p. 77) points out, in the sexual act performed with geese, chickens, etc., the sight of the dying animal and its death-struggles at the time of coitus afford complete satisfaction. The perverse sexual acts with adults are quite as horrible, and may be explained psychologically in the same way. Case 49, in the author’s “Text-Book of Legal Psychopathology,” second ed., p. 161, demonstrates how enormously increased sexual lust may be during the course of senile dementia. Quum senex libidinosus germanam suam filiam æmulatione motus necaret et adspectu pectoris sciosi puellæ moribundæ delectaretur. Erotic delirium and states of satyriasis may occur, in the course of the malady, with or without maniacal episodes, as the following case shows:— Case 1. J. René, always given to indulgence in sensuality and sexual pleasures, but always with regard for decorum, has shown, since his seventy-sixth year, a progressive loss of intelligence and increasing perversion of his moral sense. Previously bright and outwardly moral, he now wasted his property in concourse with prostitutes, frequented brothels only, asked every woman on the street to marry him or allow coitus, and thus became so publicly obnoxious that it was necessary to place him in an asylum. There the sexual excitement increased to a veritable satyriasis, which lasted until he died. He masturbated continuously, even before others; took delight only in obscene ideas; thought the men about him were women, and followed them with indecent proposals (Legrand du Saulle, “La Folie,” p. 533). Moreover, women previously moral, when affected with senile dementia, may manifest similar conditions of great sexual excitement (nymphomania, furor uterinus). It may be seen from a reading of Schopenhauer,[37] that, as a result of senile dementia, the abnormally excited and perverse instinct may be directed exclusively to persons of the same sex (_v. infra_). The manner of the satisfaction is here passive pederasty, or, as I ascertained in the following case, mutual masturbation:— Case 2. Mr. X., aged 80, of high social position, from a family having hereditary taint. He was always very sensual and a cynic, of uncontrollable temper, and, according to his own confession, as a young man, preferred masturbation to coitus. However, he never showed signs of contrary sexual instinct, and kept mistresses, raising a child by one. At the age of forty-eight he married, out of inclination, and begat six children, and never gave his wife cause for complaint. I could obtain but an incomplete history of his family. It was certain that his brother was suspected of love for men, and that a nephew became insane as a result of excessive masturbation. The patient, always peculiar and quick-tempered, for years has been growing more extreme in character. He has become exceedingly suspicious, and slight opposition to his wishes induces attacks of anger which may become actual raving, and in which he may raise his hand against his wife. For a year there have been unmistakable signs of incipient senile dementia. The patient has become forgetful, localizes past events incorrectly, and has false ideas of time. For fourteen months it has been noticed that he manifests affection for certain male servants, especially for a gardener’s boy. Otherwise rude and overbearing to servants, he surfeits his favorite with favors and presents, and commands his family and his house officials to treat the boy with the greatest respect. The aged patient awaits the hour of rendezvous in true sexual excitement. He sends his family away, that he may be with his favorite undisturbed, and remains shut up with him for hours; and when the doors are opened again, he is found lying on the bed exhausted. Besides this object of his passion, the patient had intercourse episodically with other servants. It is certain that he enticed them, asked them for kisses, exhibited himself, allowed manipulation ad genitalia, and practiced mutual masturbation. By these practices absolute demoralization was brought about. The family was powerless; for any opposition caused violent outbreaks of anger and even threats against his relatives. The patient was completely without appreciation of his perverse sexual acts; and therefore the only course left to the afflicted family was to remove all authority from his hands and place him in an asylum. No erotic inclination toward the opposite sex was observed, though the patient occupied a sleeping-apartment with his wife. With reference to the perverse sexuality and the defective moral sense of this unfortunate man, it is worthy of note that he questioned the servants of his daughter-in-law as to whether she had a lover. B. ANÆSTHESIA SEXUALIS (ABSENCE OF SEXUAL FEELING). _1. As a Congenital Anomaly._ Only those cases can be regarded as unquestionable examples of absence of sexual instinct dependent on cerebral causes, in which, in spite of generative organs normally developed and the performance of their functions (secretion of semen, menstruation), the corresponding emotions of sexual life are absolutely wanting. These functionally sexless individuals are seldom seen, and are, indeed, always persons having degenerative defects, and in whom other functional cerebral disturbances, states of psychical degeneration, and even anatomical signs of degeneration, are observed. Legrand du Saulle describes a classical case that falls under this head (_Annales médico-psychol._, May, 1876). Case 3. D., aged 33, had a mother who suffered with insanity of persecution. The mother’s father also suffered with persecutory insanity, and committed suicide. Her mother was insane, and this woman’s mother became insane in the puerperal state. Three of her mother’s children died in babyhood, and those that lived longer had an abnormal character. As early as his thirteenth year, D. was troubled with the thought of becoming insane. At fourteen he attempted suicide. Later, vagabondage, and, as a soldier, repeated insubordination and crazy pranks. His intelligence was very limited; no sign of degeneration, genitals normal. At seventeen or eighteen he had emissions of semen, had never masturbated or had sexual feeling, and never had sought intercourse with women. Case 4. P., aged 36, common laborer, was received at my clinic in the beginning of November on account of spastic spinal paralysis. He declares he comes of a healthy family. A stutterer from his youth. Cranium microcephalic (cf. 53 cm.). Patient somewhat imbecile. He was never sociable, never had a sexual emotion. The sight of a woman never had anything enticing for him. He never had a desire to masturbate. Erections frequent, but only on waking in the morning with a full bladder, and without a trace of sexual feeling. Pollutions very infrequent,—about once a year, in sleep,—and usually while dreaming that he is concerned with a female. These dreams, however, as his dreams in general, are not markedly erotic. He says the act of pollution is not accompanied by any pleasurable sensation. Patient does not feel this absence of sexual sensations. He gives the assurance that his brother, aged 34, is in exactly the same sexual condition as himself, and he makes it seem probable that a sister, aged 21, is in a similar state. A younger brother, he says, is normal sexually. The examination of his genitals reveals nothing abnormal besides phimosis. Hammond (“Sexual Impotence”), even with his wide experience, reports only the following three cases of anæsthesia sexualis:— Case 5. Mr. W., aged 33; strong, healthy, with normal genitals. He had never experienced libido, and had vainly sought to awaken his defective sexual instinct by means of obscene stories and intercourse with prostitutes. On the occasion of such attempts he experienced only disgust, with even a feeling of nausea, and became nervously and mentally exhausted. Only once, when he forced the situation, did he have a transitory erection. W. had never masturbated, and had had pollutions about once every two months from his seventeenth year. Important interests demanded that he marry. He had no _horror feminæ_, and longed for a home and a wife, but felt that he was incapable of the sexual act. He died, unmarried, in the American civil war. Case 6. X., aged 27; genitals normal; never felt libido. Mechanical or thermic stimuli easily induced erection, but instead of libido sexualis there was regularly a desire for alcoholic indulgence. Such excesses also induced erections, and he then sometimes masturbated. He had a disinclination for women and a loathing of coitus. If, with an erection, he made an attempt at coitus, it disappeared at once. Death in coma during an attack of cerebral hyperæmia. Case 7. Mrs. O., normally developed, healthy, menstruated regularly; aged 35, fifteen years married. She never experienced libido, and never had any erotic excitement in sexual intercourse with her husband. She was not averse to coitus, and sometimes seemed to experience pleasure in it, but she never had a wish for repetition of cohabitation. In connection with such pure cases of anæsthesia there should be considered other cases in which the mental side of the vita sexualis is a blank leaf in the life of the individual, but where elementary sexual sensations manifest themselves at least in masturbation (comp. the transitional Case 6). According to Magnan’s ingenious classification, which, however, is not strictly correct and somewhat too dogmatic, in such cases the sexual life is so limited as to be designated spinal. Possibly in some such cases there exists virtually a mental side of the vita sexualis, but it is very weak, and undermined by masturbation before it attains development. These represent the transitional cases from the congenital to the acquired (psychical) anæsthesia sexualis. This danger threatens many masturbators of vicious constitution. It is psychologically interesting that when the sexual element is early vitiated, then an ethical defect is manifested. The two following cases, previously published by me in the _Archiv für Psychiatrie_, vii, are given here as illustrations worthy of consideration:— Case 8. F. J., aged 19, student; mother was nervous, sister epileptic. At the age of four, acute brain affection, lasting two weeks. As a child he was not affectionate, and was cold toward his parents; as a student he was peculiar, retiring, preoccupied with self, and given to much reading. Well endowed mentally. Masturbation from fifteenth year. Eccentric after puberty, with continual alternation between religious enthusiasm and materialism,—now studying theology, now natural sciences. At the university his fellow-students took him for a fool. He read Jean Paul almost exclusively, and wasted his time. Absolute absence of sexual feeling toward the opposite sex. Once he indulged in intercourse, experienced no sexual feeling in the act, found coitus absurd, and did not repeat it. Without any emotional cause whatever, he often had a thought of suicide. He made it the subject of a philosophical dissertation, in which he contended that it was, like masturbation, a justifiable act. After repeated experiments, which he made on himself with various poisons, he attempted suicide with fifty-seven grains of opium; but he was saved, and sent to an asylum. Patient is destitute of moral and social feelings. His writings disclose incredible frivolity and vulgarity. His knowledge is of a wide range, but his logic is peculiarly distorted. There is no trace of emotionality. He treats everything (even the sublime) with incomparable cynicism and irony. He pleads for the justification of suicide with false philosophical premises and conclusions, and, as one would speak of the most indifferent affair, he declares that he intends to accomplish it. He regrets that his penknife has been taken from him. If he had it he would open his veins as Seneca did,—in the bath. A short time before a friend had given him, instead of a poison as he supposed, a cathartic. Instead of having been a means to send him to the other world, it had sent him to the water-closet. Only the Great Operator could eradicate his foolish and fatal idea by removing his senses, etc. The patient has a large, rhombic, distorted skull, the left half of the forehead being flatter than the right. The occiput is very straight. Ears far back, widely projecting, and the external meatus forms a narrow slit. Genitals very lax; testicles unusually soft and small. Now and then the patient suffers with onomatomania. He is compelled to think of the most useless problems and give up to an interminable distressing and worrying thought; and is so fatigued after it that he is no longer capable of any rational thought. After some months the patient was sent home unimproved. There he spent his time in reading and frivolities, and busied himself with the thought of founding a new Christianity, because Christ had been subject to grand delusions and had deceived the world with wonders (!). After remaining at home some years the sudden occurrence of a maniacal outbreak brought him again to the asylum. He presented a mixture of primordial delirium of persecution (devil, anti-christ, persecution, poisoning, persecutory voices) and delusions of grandeur (Christ, redemption of the world), with impulsive, incoherent actions. After five months there was a remission of this intercurrent acute mental disease, and the patient returned to the level of his original intellectual peculiarity and moral defect. Case 9. E., aged 30, journeyman-painter, was arrested while trying to cut off the scrotum of a boy he had caught in the woods. He gave as a motive for this act that he wished to cut into it in order that the world should not multiply. Often in his youth, with like purpose, he had cut into his own genitals. It is impossible to learn anything of his ancestry. From his childhood he was mentally abnormal, violent, never lively, very irritable, irascible, selfish, and weak-minded. He hated women, loved solitude, and read much. He sometimes laughed to himself and did silly things. Of late years his hatred of women had increased, especially of those that were pregnant, they being responsible for the misery of the world. He also hated children, and cursed his father. He entertained communistic ideas, and berated the rich and the ministry, and God, who had allowed him to come into the world so poor. He declared that it would be better to castrate all children than to allow others to come into the world that could only be fated to endure poverty and misery. He had always had the intention, from his fifteenth year, to castrate himself, in order to have no part in increasing unhappiness and adding to the number of men. He hated the female sex because it was a means of procreation. Only twice in his life had he allowed women to practice manustupration on him, and, with the exception of this, he had never had anything to do with them. Occasionally he had sexual desire, but never for a natural satisfaction of it. When nature did not help him, he occasionally helped himself by means of masturbation. He is a powerful, muscular man. The formation of the genitals presents no abnormality. On the scrotum and penis are numerous scars, which resulted from his attempts at self-emasculation, but which, he asserts, were not carried out on account of pain. Genu valgum of right limb. No evidence of onanism could be discovered. He is moody, defiant, irritable. Social feelings are absolutely foreign to him. With the exception of imperfect sleep and frequent headaches, there are no functional disturbances. From cases of this kind, depending on cerebral causes, there must be distinguished others where the absence of function arises from an absence or malformation of the generative organs, as in certain hermaphrodites, idiots, and cretins. A case belonging here is found in Maschka’s hand-book. Case 10. Complainant pleads for divorce on account of impotence of her husband, who has never had intercourse with her. She is thirty-one years old, and a virgin. The husband is somewhat weak mentally, physically strong; the genitals well developed. He declares that he has never had a complete erection or a flow of semen, and says that he is totally indifferent about intercourse with women. Ultzmann’s[38] observations show that anæsthesia sexualis is not caused by aspermia simply. He shows that even in congenital aspermia the vita sexualis and sexual power may be entirely satisfying; an additional proof that defective libido _ab origine_ is to be sought for in cerebral conditions. The _naturæ frigidas_ of Zacchias are examples of a milder form of anæsthesia. They are met more frequently among women than among men. The characteristic signs of this anomaly are: slight inclination to sexual intercourse, or pronounced disinclination to coitus without sexual equivalent, and failure of corresponding psychical, pleasurable excitation during coitus, which is indulged in simply from sense of duty. I have often had occasion to hear complaints from husbands about this. In such cases the wives have always proved to be neuropathic _ab origine_. Some were at the same time hysterical. _2. Acquired Anæsthesia._ Acquired diminution of sexual instinct, extending through all degrees to extinction, may depend on various causes. These may be organic and functional, psychical and somatic, central and peripheral. The diminution of libido, as age advances, and its temporary disappearance after the sexual act, are physiological. The variations with reference to the duration of the sexual instinct are dependent upon individual factors. Education and manner of life have a great influence upon the intensity of the vita sexualis. Intense mental activity (hard study), physical exertion, emotional depression, and sexual continence decidedly diminish sexual inclination. Continence at first induces increase, but sooner or later, according to constitutional conditions, the activity of the generative organs decreases, and with it libido. At all events, in a person sexually mature, a close connection exists between the activity of the generative glands and the degree of libido. That this relation is not determinate is shown by the cases of sensual women, who, after the climacterium, continue to have sexual intercourse, and may manifest states of sexual excitement (cerebral). Also in eunuchs it is seen that libido may long outlast the production of semen. On the other hand, however, experience teaches that libido is essentially conditioned by the function of the generative glands, and that the facts mentioned are exceptional manifestations. As peripheral causes of diminution or extinction of libido, may be mentioned castration, degeneration of the sexual glands, marasmus, sexual excesses in the form of coitus and masturbation, and alcoholism [cocainism]. In the same way, the disappearance of libido in general disturbances of nutrition (diabetes, morphinism, etc.) may be explained. Finally, the atrophy of the testicles should be remembered, which has sometimes been observed to follow focal lesions of the brain (cerebellum). A diminution of the vita sexualis, from degeneration of the tracts of the cord and genito-spinal centre, occurs in diseases of the spinal cord and brain. A central interference with the sexual instinct may be organically induced by cortical disease (dementia paralytica in its advanced stages); functionally, by hysteria (central anæsthesia?) and emotional insanity (melancholia, hypochondria). C. HYPERÆSTHESIA (ABNORMALLY INCREASED SEXUAL DESIRE). Pathology has no easy task, in the single case, when it has to decide whether the impulse to sexual satisfaction has reached a pathological degree. Emminghaus (“Psychopathologie,” p. 225) declares that the immediate re-awakening of desire after satisfaction, with its occupation of the entire attention, and no less the excitation of libido by the sight of persons and things which in themselves should have but an indifferent sexual effect, are decidedly abnormal. In general, sexual instinct and its corresponding needs are in proportion to physical strength and age. Sexual desire rapidly increases after puberty, until it reaches a marked degree; is strongest from the twentieth to the fortieth year, and then slowly decreases. Married life seems to preserve and control the instinct. Sexual intercourse with many persons increases the desire. Since woman has less sexual need than man, a predominating sexual desire in her arouses a suspicion of its pathological significance; and the more, when this finds expression in desire for adornment, coquetry, or male society, which, passing beyond the limits set by good breeding and manners, becomes quite noticeable. The constitution, in both sexes, is of the greatest significance. An abnormally strong sexual instinct is frequently accompanied by a neuropathic constitution; and such individuals pass a great part of their lives heavily burdened with the weight of this constitutional anomaly of their sexual life. The power of the sexual impulse in such cases may at times rise to the importance of an organic necessity, and really endanger the freedom of the will. The want of satisfaction of this impulsive desire may, under such conditions, induce a condition allied to actual rutting, or a psychical condition, accompanied by emotions of fear, in which the individual gives up to the impulse, and responsibility becomes doubtful. If the individual does not give up to his powerful impulse, he is in danger, by reason of his enforced abstinence, of ruining his nervous system by inducing a neurasthenia, or seriously increasing such a condition if it be already present. In normally constituted individuals, too, the sexual instinct is an inconstant quantity. Aside from the temporary indifference following satisfaction, and the diminution of sexual desire in long-continued continence after a certain reactionary stage of sexual desire is overcome, the manner of life has a great influence. Those living in large cities, who are constantly reminded of sexual things and incited to sexual enjoyment, certainly have more sexual desire than those living in the country. A dissipated, luxurious, sedentary manner of life, preponderance of animal food, and the consumption of spirits, spices, etc., have a stimulating influence on the sexual life. In woman the sexual inclination is post-menstrually increased. At this time, in neuropathic women, the excitement may reach a pathological degree. The great libido of consumptives is remarkable. Hofmann tells of a consumptive peasant who satisfied his wife sexually on the evening before his death. The sexual acts are coitus (eventually rape) and, _faute de mieux_, masturbation; and, with defective moral sense, pederasty or bestiality. If sexual power is diminished or extinct, with excessive sexual desire, all manner of perversity of sexual acts becomes possible. Excessive libido may be peripherally or centrally induced. The former manner of origin is the more infrequent. Pruritus and eczema of the genitals may cause it; and likewise certain substances, like cantharides, which powerfully stimulate sexual desire. Not infrequently, in women at the climacteric, sexual excitement occurs, occasioned by pruritus; and also in cases where there is neuropathic taint. Magnan (_Annales médico-psychol._, 1885, p. 157) reports the case of a lady who was afflicted mornings with attacks of frightful erethismus genitalis, and the case of a man, aged 55, who was tormented at night by unbearable priapism. In each case there was a neurosis. The central origin of sexual excitement is of frequent occurrence[39] in persons having neurotic taint or hysteria, and in conditions of psychical exaltation. Here, where the cortex and the psycho-sexual centre are in a condition of hyperæsthesia (abnormal excitability of the imagination, increased ease of association), not only visual and tactile impressions, but also auditory and olfactory sensations, may be sufficient to call up lascivious concepts. Magnan (_op. cit._) reports the case of a young woman who had an increasing sexual desire from puberty, and satisfied it by masturbation. Gradually she grew to become sexually excited at the sight of any man pleasing to her; and, since she was unable to control herself, she would sometimes shut herself up in a room until the storm had passed. At last she gave herself up to men of her choice, that she might get rest from her tormenting desire; but neither coitus nor masturbation brought relief, and she went to an asylum. The case of a mother of five children is added, who, in despair about her inordinate sexual impulse, attempted suicide, and then sought an asylum. There her condition improved, but she never trusted herself to leave it. There are several illustrative cases in men and women in the author’s article, “On Certain Anomalies of Sexual Instinct,” Cases 6 and 7 (_Archiv für Psychiatrie_, vii, 2); Cases 3 and 5 are given here. Case 11. On the afternoon of July 7, 1874, Clemens, engineer, being on his way, on business, from Trieste to Vienna, left the train at the town of Bruck, and, passing through the town to the neighboring village of St. Ruprecht, attempted a rape on an old woman, aged 70, whom he found alone in a house. He was seized by the neighbors and arrested by the local police. At his hearing he declared that he had tried to find the pound, in order to satisfy his sexual desire with a bitch. He said that he often suffered with such sexual excitement. He did not deny his act, but excused it as the result of disease. The heat, the motion of the cars, and anxiety about his family, to which he wished to go, had confused him and made him ill. Shame and remorse were not shown. His conduct was open, his mien gay; eyes red and bright, head hot, tongue coated; pulse full, soft, beating over 100; fingers somewhat tremulous. The statements of the accused were precise, but hurried; his glance uncertain, and with an unmistakable expression of lasciviousness. To the medical expert summoned to examine him, he gave the impression of one suffering with disease,—as if he were in the beginning of alcoholic insanity. C. is forty-five years old, married, father of one child. He does not know what diseases his parents or other members of his family have had. In childhood he was weak and neuropathic. At the age of five his head was injured by a blow with a hoe. A scar one-half cm. broad by one cm. long, situated on the right parietal and frontal bones, dates from that injury. The bone is here somewhat depressed. The overlying skin is united to the bone. Pressure at this point causes pain, which radiates along the lower branch of the trigeminus. This spot is also frequently spontaneously painful. In his youth he had frequent attacks of “fainting”; before puberty, pneumonia, rheumatism, and intestinal catarrh. At the age of seven he experienced a peculiar inclination for men,—_i.e._, for a certain superior. Whenever he saw this man he had a peculiar feeling in his heart; kissed the ground he walked on. At ten he fell in love with a certain deputy. Later he had an enthusiasm for men, though it was entirely platonic. He began to masturbate at the age of fourteen; first intercourse at seventeen. Then the earlier manifestations of contrary sexual feeling disappeared entirely. At that time he passed through a peculiar acute psychopathic condition, which he described as a kind of clairvoyance. From fifteen, hæmorrhoids, with symptoms of plethora abdominalis. When he had profuse hæmorrhoidal hæmorrhage, which occurred usually every three or four weeks, he was better. At other times he was constantly in a condition of painful sexual excitement, which he satisfied partly by means of onanism and partly by coitus. Every woman he met excited him; even when he was among female relatives he was impelled to make indecent proposals. Sometimes it was possible for him to master his desire; sometimes he was driven to indecent acts. If, after these, he was kicked out-of-doors, it seemed perfectly right to him; for he thought that he needed such correction and support against his powerful impulse, which was a burden to him. No periodicity in this sexual excitement was recognizable. Until 1861 he committed excesses in venery and was several times infected with gonorrhœa and chancres. In 1861, marriage. He was sexually satisfied, but became a burden to his wife on account of his great sensuality. In 1864 he passed through an attack of mania in the hospital at Fiume, and in the same year he again fell ill, and was taken to the insane asylum at Ybbs, where he remained until 1867. There he suffered with recurrent mania accompanied by great sexual excitement. He says that intestinal catarrh and anxiety were the cause of his illness at that time. Thereafter he was well, but he suffered much on account of his excessive sexual desire. If he were absent from his wife but a short time, the impulse became so powerful that man or animal was indifferent to him for the satisfaction of his lust. In summer these impulses were much stronger, and were always accompanied by abdominal plethora. Something that he remembered in medical reading, made him think that in his case the ganglionic system was more powerful than the cerebral. In October, 1873, on account of business, he had to leave his wife. From that time until Easter, with the exception of occasional masturbation, there was no sexual indulgence. After that he made use of women and bitches. From the middle of June until July 7, he had no opportunity for sexual indulgence. He felt nervously excited, relaxed, and as if he were going crazy. Of late he had slept badly. A longing for his wife, who lived in Vienna, drove him to leave his business. He obtained leave of absence. The heat and the noise of the train confused him, and he could no longer hold out against his sexual excitement and the pressure of blood in his abdomen. Everything danced before his eyes. He left the car at Bruck, and was absolutely confused, not knowing where he went; and for a moment the thought came to him to throw himself in the water; all was like a mist before his eyes. Then he saw a woman, exposed his genitals, and tried to embrace her. She cried for help, and thus he was arrested. After the attempt it suddenly became clear to him what he had done. He openly confessed his crime, which he remembered in all its details, but which seemed to him to be something abnormal. He could not help it. For some days after this, C. suffered with headache and congestions, and was now and then excited and restless, and slept badly. His mental functions are undisturbed, but he is, nevertheless, a congenitally peculiar man, with a character weak and devoid of energy. The facial expression has something lascivious and peculiar about it. He suffers with hæmorrhoids. The genitals present nothing abnormal. The cranium is narrow and retreating at the forehead. Body large and well nourished. With the exception of diarrhœa, there is no disturbance of the vegetative functions. Case 12. Mrs. E., aged 47. Uncle on father’s side was insane; father was sanguine, and given to excess in venery. Patient’s brother died of an acute cerebral affection. Patient from childhood has been nervous, eccentric, and romantic; and while little more than a child manifested excessive sexual desire, and at ten began sexual indulgence. At nineteen, marriage. Unhappy married life; her husband, who was normal, did not satisfy her, and until recent years she constantly had other friends besides her husband. She was well aware of the immorality of her life, but felt her powerlessness against her insatiable desire, which she sought to keep, at least outwardly, a secret. Later she thought that she had suffered with a “mania for men.” Patient has borne six children. Six years ago she was thrown from a wagon and received a severe cerebral concussion. Following this there was melancholia, with delusions of persecution, which sent her to the asylum. She is approaching the climacterium, and of late the menses have been profuse and too frequent. Since this period she is pleased to note that the previously powerful sexual impulse has declined. Proper behavior. Slight degree of descensus uteri and prolapsus ani. Hyperæsthesia sexualis may be continuously present with exacerbations, or it may be intermittent or periodic. In the latter case it is a cerebral neurosis _per se_ (_vide_ “Special Pathology”), or an accompanying symptom of a condition of general psychical excitement (mania; episodically in dementia paralytica, dementia senilis, etc.). Lentz has published a remarkable case of intermittent satyriasis (_Bulletin de la société de méd. légale de Belgique_, Nr. 21):— Case 13. For three years the generally respected farmer D., married, aged 35, has manifested states of sexual excitement, with increasing frequency and severity, which, during the past year, have become true paroxysms of satyriasis. It was impossible to discover hereditary or other organic cause. D. was compelled, at times when his sexual excitement was excessive, to perform the sexual act from ten to fifteen times in twenty-four hours, without deriving any feeling of satisfaction. Gradually he developed a condition of general nervous hyper-irritability (_éréthisme général_) with increased emotional irritability to the extent of pathological outbreaks of anger, and impulse to over-indulgence in alcohol, which induced symptoms of alcoholism. His attacks of satyriasis became so violent that consciousness was interfered with, and the patient raged about in blind impulse to sexual acts. He demanded that his wife give herself to other men or to animals in his presence; that she allow copulation with him, _presentibus filiabus_, because this would afford him greater enjoyment. Memory for the events at the height of these attacks, in which the extreme irritability even led to outbreaks of maniacal rage, was entirely wanting. D. himself thought that he must have had moments in which he no longer had control of his senses, and without satisfaction from his wife would have been compelled to seize the next best female. After an attack of violent emotion, these attacks of sexual excitement suddenly disappeared entirely. The two following cases show how powerful, dangerous, and painful sexual hyperæsthesia may become in those afflicted with this anomaly:— Case 14. _Hyperæsthesia Sexualis_—_Delirium Acutum ex Abstinentia._—On May 29, 1882, F., aged 29, single, shoemaker, was received at the clinic. Father was of passionate temper; mother neuropathic, and had an insane brother. Patient had never been seriously ill previously, and was not a drinker, but had always been sexually very passionate. Five days before, he was taken acutely ill mentally. He made two attempts at rape in broad daylight, before witnesses, and when arrested talked in delirium only of obscene things, and masturbated without stint, and for three days had been raving mad. On admission he presented the picture of a severe acute delirium, with violent motor symptoms of irritation, and fever. Under treatment with ergotin a cure was effected. On January 5, 1888, second admission, in a state of violent mania. On January 4, he had become morose, irritable, whining, and sleepless; and then, after vain assaults on women, had manifested symptoms of increasing angry excitement. On January 6, progress of the condition to severe acute delirium (great disturbance of consciousness, jactation, grinding of the teeth, grimacing, and other motor symptoms of irritation; temperature as high as 40.7° C.); impulsive masturbation. Recovery was complete by January 11, under energetic treatment with ergotin. After his recovery the patient gives an interesting account of the cause of his illness. Always very passionate sexually; first coitus at the age of sixteen. Continence caused headache, great psychical irritability, lassitude, great loss of pleasure in work, and sleeplessness. Since he had few opportunities in the country to satisfy his desire, he had recourse to masturbation. It was necessary for him to masturbate once or twice daily. No coitus in two months. Increasing sexual excitement; could think of nothing save means for the gratification of his impulse. Masturbation was not sufficient to banish the constantly increasing torment _ex abstinentia_. During the last four days violent impulse to coitus; increasing sleeplessness and irritability. There was only a summary recollection of the height of the illness. Patient recovered in December. A very respectable man; he considers his inordinate desire decidedly pathological, and is anxious about his future. Case 15. On July 11, 1884, R., aged 33, servant, was admitted suffering with paranoia persecutoria and neurasthenia sexualis. Mother was neuropathic; father died of spinal disease. From childhood he had an intense sexual desire, of which he became conscious as early as his sixth year. From this age, masturbation; from fifteenth year, _faute de mieux_, pederasty; occasionally, sodomitic indulgences. Later, abusus coitus in marriage cum uxore. Now and then even perverse impulse to commit cunnilingus and to administer cantharides to his wife, because her libido did not equal his own. His wife died after a short period of married life. Patient’s circumstances became straightened, and he had no means to indulge himself sexually. Then masturbation again; employment of lingua canis to induce ejaculation. At times, priapism and conditions approaching satyriasis. He was then driven to masturbate, in order not to become stuporous. Beneficial diminution of the libido nimia, with the gradually predominating sexual neurasthenia and hypochondria. The following case, valuable for an understanding of many Messalinas, some of whom are historically celebrated, is a classical example of pure hyperæsthesia sexualis, which I take from Trelat’s “Folie lucide”:— Case 16. Mrs. V. has suffered with a passion for men since her earliest youth. Of good family, well bred, of pleasant disposition, exceedingly modest, she was, as a little girl, a terror to her family, because she could scarcely be alone with a person of the opposite sex, no matter whether it was with child or man of any age, without exposing herself immediately and demanding satisfaction for her sexual passion, even going so far as to lay hold of him. An attempt was made to cure her by marriage. She loved her husband passionately, but even with him she could not keep from demanding coitus of every one with whom she could be alone, no matter whether it was servant, laborer, or school-boy. Nothing could cure her of this impulse. Even when she became a grandmother, she was still a Messalina. One day she locked a twelve-year-old boy in her room and tried to seduce him. The boy defended himself and escaped. She was severely punished by his brother. All was in vain. She was put in a cloister. There she was an example of morality, and gave not the slightest cause for blame. Immediately after her return the scandal began again. The family banished her, and set aside money to support her. She earned by her own hand-work enough to buy herself lovers. Any one seeing this neatly dressed matron, of good manners and amiable disposition, would never suspect how recklessly passionate she still was at the age of sixty-five. On January 7, 1854, her family, in despair at new scandals, placed her in an asylum. She lived there until May, 1858, when she died of apoplexia cerebri, in her seventy-third year. Her conduct in the asylum was exemplary. Left to herself, and under favorable conditions, her sexual impulses manifested themselves shortly before her death. With the exception of this, during an observation of four years by physicians of the asylum, she never showed a sign of mental abnormality. D. PARÆSTHESIA OF SEXUAL FEELING (PERVERSION OF THE SEXUAL INSTINCT). In this condition there is perverse emotional coloring of the sexual ideas. Ideas physiologically and psychologically accompanied by feelings of disgust, give rise to pleasurable sexual feelings; and the abnormal association finds expression in passionate, uncontrollable emotion. The practical results are perverse acts (perversion of the sexual instinct). This is more easily the case if the pleasurable feelings, increased to passionate intensity, inhibit any opposing ideas with corresponding feelings of disgust; or the influence of such opposing concepts may be impossible on account of the absence or loss of all ideas of morality, æsthetics, and law. This loss, however, is only too frequently found where the spring of ethical ideas and feelings (a normal sexual instinct) has been poisoned from the beginning. With opportunity for the natural satisfaction of the sexual instinct, every expression of it that does not correspond with the purpose of nature,—_i.e._, propagation,—must be regarded as perverse. The perverse sexual acts resulting from paræsthesia are of the greatest importance clinically, socially, and forensically; and, therefore, they must here receive careful consideration; all æsthetic and polite disgust must be overcome. Perversion of the sexual instinct, as will be seen from what follows, is not to be confounded with perversity in the sexual act; since the latter may be induced by conditions which are not psychopathology. The concrete perverse act, monstrous as it may be, is not decisive. In order to differentiate between disease (perversion) and vice (perversity), one must investigate the whole personality of the individual and the original impulse leading to the perverse act. Therein will be found the key of diagnosis (_v. infra_). Paræsthesia may occur in combination with hyperæsthesia. This association seems to be frequent clinically. Sexual acts are then confidently to be expected. The perverse direction of sexual activity may be toward sexual satisfaction with the opposite or the same sex. Thus two great groups of perversions of the sexual life may be distinguished. _1. Sexual Inclination toward Persons of the Opposite Sex, with Perverse Activity of the Instinct._
