as far as possible, from his brothers and sisters to save
these latter from being corrupted by him. But notwithstanding this
precaution, by the time he was five years old he had begun to make
sexual attacks on a sister one year older than himself. He was cunning
enough to arrange matters in such a way that he was alone with his
sister, at times when the usual safeguards to keep him separate from the
other children were suspended--for example, when his parents were away,
and when his governess (who had been made fully acquainted with the
circumstances) was keeping some assignation of her own. (All this was
fully elucidated at a later date. The distressed parents were foolish
enough to imagine that a child with inherited morbid predispositions of
this character could be adequately safeguarded by means of hired help;
they were painfully disillusioned when it appeared that the hired
assistant, instead of watching the child, was pursuing her own
pleasures--a point in which she merely imitated the parents, themselves
earnest pleasure-seekers, deluding themselves with the belief that
everything possible was being done for their child.) Although the
parents had known all about the boy's habit of masturbation for many
years past, it was only through a fortunate accident, and after the
sexual malpractices with the sister had been going on for a long time,
that these at length came to light. It appears that the boy had from
time to time made sexual advances to other girls than his sister. One
day, while playing with the little daughter belonging to a neighbouring
family, he endeavoured to lead this child sexually astray. The little
girl told her parents what had happened, and these latter consequently
refused to allow her to play with Y. any more. This prohibition led Y.'s
parents to inquire into the whole matter with great care. It was then
discovered that for years past Y. had been engaged in sexual misconduct
with his sister, his usual method being to play with her genital organs
with his hands. In the girl, the frequent repetition of this act had
given rise to abrasions and local inflammations.

The following case, the leading features of which are the early age at
which seminal ejaculation occurred, and the marked hyperaesthesia of the
sexual impulse, may also be regarded as an example of sexual paradoxy.
This patient exhibits a number of different perverse modes of sexual
sensibility, some of which have persisted to the pres
