The following case, borrowed from my own clientele, very clearly shows the connection between lust and cruelty, with desire to shed and see blood:— Case 24. Mr. X., aged 25; father syphilitic, died of paretic dementia; mother hysterical and neurasthenic. He is a weak individual, constitutionally neuropathic, and presents several anatomical signs of degeneration. When a child, hypochondria and imperative conceptions; later, constant alternation of exaltation and depression. While yet a child of ten, the patient felt a peculiar lustful desire to see blood flow from his fingers. Thereafter he often cut or pricked himself in the fingers, and took great delight in it. Very early, erections were added to this, and also if he saw the blood of others; for example, when he saw a servant-girl cut her finger it gave him an intense lustful feeling. From this time his vita sexualis became more and more powerful. Without any teaching he began to masturbate, and always during the act there were memory-pictures of bleeding girls. It now no longer sufficed him to see his own blood flow; he longed to see the blood of young females, especially those that were attractive to him. Often he could scarcely overcome the impulse to injure two cousins and a certain servant. But also young women that were in themselves not attractive induced this impulse when they excited him by some peculiarity of dress or adornment, especially coral jewelry. It was necessary for him to overcome these desires; but in his imagination bloody thoughts were constantly present, and induced lustful excitement. There was an inner relation existing between both thoughts and feelings. Often there were other cruel fancies. He imagined himself in the _rôle_ of a tyrant who had the people shot in crowds with grape-shot. He was compelled to fancy a scene as it would be if enemies were to take a city and mutilate, torture, kill, and rape the young women. In times of quiet this patient, who had a mild disposition and was not morally defective, was shamed and horrified by such cruel, lustful fancies, and they always became immediately latent as soon as his sexual excitement had been satisfied by masturbation.
