ter, and under the influence of this
attraction erections occasionally occurred. Somewhat later came the time
when I began to masturbate. I can no longer remember with certainty
whether I was seduced to this practice by any of my school-fellows. We
sometimes talked to one another about the matter. I continued at times
to be influenced by the inclinations previously mentioned, viz., that
for my schoolmaster, and that for my friend's sister. I experienced also
transient passion for one of my school-fellows, who was remarkable for
his pleasing and delicately girlish exterior. It was not until several
years had elapsed, and the occurrence of seminal emissions had shown
that I had attained some degree of sexual maturity, that all inclination
towards the male sex disappeared, and the inclination towards the female
sex persisted in isolation. When I left the town, in order to attend a
different school, my fondness for my friend's sister passed away. I was
then sixteen years of age; from this time onwards my sexual passion was
exhibited exclusively towards members of the female sex."

CASE 2.--This case provides us with another description of the
undifferentiated sexual impulse. X. is thirty years of age. No morbid
condition is demonstrable in him. He remembers that the first sentiments
which he regards as sexual were experienced by him in the country. His
home was in a town, but during the holidays he was sent to board in the
country, in the house of a clergyman. He played much in the open air,
and he still recalls quite distinctly the passion with which, first of
all, he approached animals. "As if by an irresistible impulse I was
attracted, now by a goat, now by a dog, sometimes even by a horse. No
excitement of the genital organs was noticeable at this time, but I have
no doubt whatever now that these inclinations were sexual in their
nature. Not only did I touch the animals, but I embraced them and kissed
them. The warmth and the odour proceeding from such an animal, which is
now as a rule distasteful to me, was then a source of pleasure. When I
left the country, I took these memories away with me, but gradually they
faded and became faint. Next a fondness for one of my school-fellows
became most marked, and this lasted for a long time. I know not how to
describe the feeling I had for him otherwise than as an immeasurable,
passionate love. I was unhappy when I sat above him in the class.
Occasionally we sat side by side, but
