HISTORY I.--E.T. (I reproduce this history, written in the third person, as it reached my hands.) T.'s earliest recollections of ideas of a sexual character are vaguely associated with thoughts upon whipping inflicted on companions by their parents, and sometimes upon his own person. About the age of 7 T. occasionally depicted to himself the appearance of the bare nates and genitalia of boys during flagellation. Reflection upon whipping gave rise to slight curious sensations at the base of the abdomen and in the nerves of the sexual system. The sight of a boy being whipped upon the bare nates caused erection before the age of 9. He cannot account for these excitations, as at the time he had not learned the most rudimentary facts of sex. The spectacle of the boy's nudity had no attraction for him, while the beating aroused his indignation against the person who administered it. T. knew a boy and girl of about his own age whose imaginations dwelt somewhat morbidly upon whipping. The three used to talk together about such chastisement, and the little girl liked to read "stories that had whippings in them." None of these children delighted in cruelty; the fascination in the theme of castigation seemed to be in imagining the spectacle of the exposed nates, though actual witnessing of the whipping made them angry at the time. Accustomed to watch a young sister being bathed, T. had no distinct curiosity concerning the differences in sex until the age of 9. About this time he asked his father where babies came from, and was told to be quiet. When he persisted in the inquiry his father threatened to box his ears. His mother told him subsequently that doctors brought babies to mothers. He credited the story so far as to carefully watch the doctor who came when his mother "was going to have a new baby," in the hope of seeing a bundle in his arm. T. was 9 when he interrogated a servant-girl of 16 about babies and their origin. She laughed and said that one day she would tell him how children came. One Sunday this servant took T. for a country walk and initiated him in sexual intercourse, telling him he was too young to be a father, but that was the way babies were made. The girl took him into a field, saying she would show him how to do something which would make him "feel as though he was in heaven," informing him that she had often done this with young men. She then succeeded in causing erection and instructed him how to act. His feeling at the time was one of disgust; the appearance and odor of the female genitalia repelled him. Afterward, however, he wished to repeat the experience with girls of his own age. Finding the boy unresponsive, the girl took the masculine position and embraced him with great passion. T. can recall the expression of the
