organic impulses arising in the sexual organs, as well as all concepts, and visual, auditory, and olfactory sense-impressions, fail to excite the individual sexually. This is physiological in childhood and old age.
3. Hyperæsthesia (increased desire, satyriasis). In this state there is an abnormally increased impressionability of the vita sexualis to organic, psychical, and sensory stimuli (abnormally intense libido, lustfulness, lasciviousness). The stimulus may be central (nymphomania, satyriasis) or peripheral, functional or organic.
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[1] 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
