The depraver of children satisfies his desires in very various ways. It will readily be understood that the progressive paralytic (paralytic dement) will act in one way, and the true paedophile in another. I shall not, however, discuss these details here, but shall merely endeavour to give some general ideas on the subject. Often, and especially at first, the depraver of children merely seeks opportunities for seeing children; then he wants to touch the children with his hands, and often to handle their genital organs; and while attempting this, or while doing it, he has ejaculation. In other cases he presses the child more and more closely into contact with himself, and especially against his own genital organs. Finally, we may have more complete sexual acts; and, especially when the child is a girl, there may be attempts at intercourse, and even defloration; where the child is a boy, pseudo-coitus may take place. The depraver of children gains his opportunities by appeals to the child's peculiar weaknesses. He will, for instance, tempt the child by the offer of sweets, and in this way will obviously often gain his ends. Many such persons hang about in the neighbourhood of a school or a children's playground, simply with this end in view. Some years ago the police of a certain large town were informed that "child-lovers" haunted a particular place. It appears that here the children were in the habit of swinging on a chain suspended between two pillars, and that the watchers waited to catch a glimpse of the children's genital organs, or merely of their bare legs, when their petticoats flew up occasionally in the act of swinging. Many paedophiles become sexually excited at the mere sight of children sympathetic to them. In other cases, by no means rare, men experience sexual excitement whenever they see a little girl with short petticoats; these men will follow such little girls all over the place, without, as a rule, speaking to them or interfering with them in any way, being withheld from doing so either by the fear of punishment or by moral restraint. To many the mere sight of the child appears to afford sufficient sexual gratification; and to others the simple contact of their hands with the child suffices, and nothing more is attempted. But, in other cases, handling the child's genital organs plays the chief part, frequently because the offender can himself obtain sexual gratification only through inducing sexual excitement in the child and watching this excitement. Sometimes, however, the offender has no interest in the child's genital organs; far from being excited sexually by regarding or handling these organs, he may even find them repulsive; but in such cases the sight of general nakedness often induces sexual excitement. This is often associated with sadistic feelings, and this alike in men and in women. In other cases, a woman will make attempts at coitus with a little boy, having first induced erection of his penis by manipulating
