In Lombroso’s case a girl of three years of age faciebat stuprum manu aperte et pæne jugiter until marriage, and even afterwards. She bore twelve children, neque desistebat a stupro manu even during pregnancy. Of her twelve children, five died in infancy, four were hydrocephalous, and the three surviving children were confirmed masturbators, the oldest having begun the practices at seven, the youngest at four years of age. One of the writer’s patients, a young woman of twenty-four years of age, incipiebat masturbari, tres annos nata, ponendo pulvinum in femoribus et premendo eum quoad muliebria humescebant. In Blackmer’s case, a girl eight years of age impudenter se stuprabat from her fourth year and, at the same time, sollicitans pueros of ten to twelve years of age ad stuprum. She planned to kill her parents that she might devote herself completely to such enjoyment. Zambaco relates the histories of two sisters, one of whom at the age of seven feminabat cum pueris, corrumpebat sororem, quattuor annos natam, ad stuprum manu, and at the age of ten was given to the practice of cunnilingus. In Moll’s case, a girl of seven had an impulsive inclination to her brother, three and a half years of age, cujus virilia amabat contrectare et quem inducebat ad contrectandum muliebria sua. Jacobi (A. Am. Jour. of Obstetr. 1876, p. 597) relates the history of a case of a girl of three who, at irregular intervals, had attacks of stuprum when sitting down. She began by keeping her thighs closely joined or by crossing her legs. She then started to move and rub her limbs violently. The face became purple, and there was twitching about the eyes which looked excited, and the child perspired freely. After the attack she used to lean back exhausted, sighing and breathing hurriedly. In another case Jacobi saw thigh friction, up and down movements, quick breathing, perspiration, in a female infant of nine months. Magnan cites a case of a seven-year-old girl who jugiter se stuprabat with great violence. Even in the moment of being photographed, she turned up her petticoat and gave herself up to her favorite pastime. Rachford (Archive of Pediatry, 1907) has collected 52 cases, 48 occurring in female and 4 in male children, of pseudomasturbation, as he calls it. But since the same symptoms of orgasm, as interrupted panting respiration, flushed cheeks, redness of face, staring eyes, large immobile pupils, perspiration and exhaustion are seen in the infant during its practice, as are found in the masturbating practices of older children, there is no reason to call these infantile manipulations by any other name than masturbation. Precocity of sexual activity is usually based upon a neuropathic predisposition. Such children are, as a rule, tainted hereditarily. The following case is very instructive on account of the severity of the attacks and the attending circumstances:
