ertaking, to be abandoned with the like precipitation.

"Having command of abundant means, I now, at the age of fifteen, became
enabled to gratify my sexual desires without restraint with dependents
of the other sex; nor did any untoward physical consequences arise to
impose limitations. After a time, ordinary sexual intercourse ceased to
furnish adequate gratification; and I began to excite myself sexually by
contact with special parts of the body, most often the breasts. But the
woman must not, as had formerly been my desire, strip herself completely
nude; for I found the most powerful sexual stimulus was now exerted by
her white drawers. The display, intentional or unintentional, of this
article of feminine attire sufficed to arouse in me sexual feelings. For
this reason I now came to frequent the skating rink, in order to obtain
a sexual stimulus from the glimpse of a woman's drawers when putting on
her skates. But even when a girl was physically beautiful and elegantly
dressed, if her drawers were not white but coloured, she produced in me
no sexual appetite whatever.

"As a result of long-continued excesses, attempts at ordinary
intercourse no longer evoked an adequate sexual stimulus, so that I now
began the practice of cunnilinctus. It was when the woman herself became
excited through the cunnilinctus, that I experienced the highest sexual
gratification. In the intervals, when I had no opportunity for sexual
intercourse, I would endeavour to secure sexual gratification by
exposing my genital organs in the presence of females, or when passing
them in the street--especially female children. I also sought every
possible opportunity of watching female dependents engaged in the act of
urination. This gave me especially great gratification if, when they
were urinating, I could see their white underlinen. I also procured
pornographic literature, and masturbated frequently while reading it."

The next period in this patient's history now begins. But I shall not
recount his case further, since the subsequent episodes have no bearing
on the questions with which we are especially concerned. It will suffice
to remark that Z. now exhibits numerous neuropathic and psychopathic
characteristics. But the various psychopathic symptoms, some of which
are very severe, lie altogether outside our chosen field of study.

Paradoxical sexual impulse is observed also in the lower animals. Weston
reports the case of a colt which when on
