as young animals do, and of
running about madly, and she would clap her hands every morning, when the
sun shone into her room, and would insist, by signs, on being dressed as
quickly as possible, so that she might get out.

"She did not appear to distinguish between people, between her mother and
her nurse, or between her father and me, or between the coachman and the
cook. I particularly liked her parents, who were very unhappy on her
account, and went to see them nearly every day. I dined with them quite
frequently, which enabled me to remark that Bertha (they had called her
Bertha) seemed to recognize the various dishes, and to prefer some to
others. At that time she was twelve years old, but as fully formed in
figure as a girl of eighteen, and taller than I was. Then the idea struck
me of developing her greediness, and by this means of cultivating some
slight power of discrimination in her mind, and to force her, by the
diversity of flavors, if not to reason, at any rate to arrive at
instinctive distinctions, which would of themselves constitute a kind of
process that was necessary to thought. Later on, by appealing to her
passions, and by carefully making use of those which could serve our
purpose, we might hope to obtain a kind of reaction on her intellect, and
by degrees increase the unconscious action of her brain.

"One day I put two plates before her, one of soup, and the other of very
sweet vanilla cream. I made her taste each of them successively, and then
I let her choose for herself, and she ate the plate of cream. In a short
time I made her very greedy, so greedy that it appeared as if the only
idea she had in her head was the desire for eating. She perfectly
recognized the various dishes, and stretched out her hands toward those
that she liked, and took hold of them eagerly, and she used to cry when
they were taken from her. Then I thought I would try and teach her to
come to the dining-room when the dinner bell rang. It took a long time,
but I succeeded in the end. In her vacant intellect a vague correlation
was established between sound and taste, a correspondence between the two
senses, an appeal from one to the other, and consequently a sort of
connection of ideas--if one can call that kind of instinctive hyphen
between two organic functions an idea--and so I carried my
experiments further, and taught her, with much difficulty, to recognize
meal times by the clock.

"It was impossible for me for a
