A clerk in a solicitor's office, at Alton, Hampshire, England, one afternoon took a walk outside the town, when he met some children. He persuaded one of these, a girl of nine, to go with him into a neighboring garden. A short while after, he was seen walking quietly home; he was seen to wash himself in the river and then go back to his office. The little girl did not return home, and, search having been instituted, her dismembered body was found strewn about the garden. The clerk was arrested, and in his diary was found this entry, recently made: "Killed a little girl; it was fine and hot." This man was either a sadistic sexual pervert, or a victim of homicidal impulse. Maudsley gives this instance as an example of the latter, while Krafft-Ebing gives it as an example of the former. There is a great difference between these two mental derangements. The victim of homicidal impulse kills without any ulterior object, while the sadist kills in order to gratify his unnatural and perverted sexual appetite. The victim of homicidal impulse is, to all outward appearances, perfectly sane otherwise. His impulse frequently leaves him for years and then returns with overpowering force. Epileptics who have just passed through violent convulsions, will frequently attack bystanders with great fury. Some alienists declare that homicidal mania is frequently only a masked epilepsy. All epileptics should be carefully watched; they may become dangerous to society at any moment. Numerous instances are recorded of murder committed by sufferers from _petit mal_, a form of epilepsy. I once saw a negro walk up to a white man, who was a stranger and unknown by him, and fell him to the earth by striking him with a club. The negro was arrested, and the next day swore that he was entirely unconscious of having struck anyone. It was proven at his trial that he was subject to mild epileptic attacks. I believe that all suicides are due to mental aberration. It may be the result of a momentary and sudden loss of mental equipoise, or the final and fatal ending of a premeditated desire carried through days, weeks, months, and even years. We see a man, blessed with everything that makes life enjoyable, genial, gay, with a ready smile and kindly word for everyone, suddenly, in a moment, pass forever out into the unknown--self-killed, a victim of his own creation. We stand amazed! Why did he do it? We can find nothing in his past or present condition to warrant such an action. He was the victim of momentary aberration, or, perhaps, deep in his mind, buried and hidden even from himself, there dwelt a desire for self-slaughter, when a "physical pain, an unexpected impression, a moral affection, an indiscreet proposition" uncovered this desire, and he at once committed the deed!
