"She began to walk very early, but she could not talk. At first I thought she was deaf, but I soon discovered that although she heard perfectly, she did not understand anything that was said to her. Violent noises made her start and frightened her, without her understanding how they were caused.
"She grew up into a superb woman, but she was dumb, from an absolute want of intellect. I tried all means to introduce a gleam of sense into her head, but nothing succeeded. I thought that I noticed that she knew her nurse, though as soon as she was weaned, she failed to recognize her mother. She could never pronounce that word, which is the first that children utter, and the last which soldiers murmur when they are dying on the field of battle. She sometimes tried to talk, but she produced nothing but incoherent sounds.
"When the weather was fine, she laughed continually, and emitted some low cries which might be compared to the twittering of birds; when it rained she cried and moaned in a mournful, terrifying manner, which sounded like the howling of a dog when a death occurs in a house.
"She was fond of rolling on the grass, like young animals do, and of running about madly, and she used to clap her hands every morning, when the sun shone into her room, and would jump out of bed and 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 liked her parents, who were very unhappy on her account, very much, and went to see them nearly every day. I dined with them tolerably 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 these means to try and produce some slight powers of distinguishing into 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 species of work that was material to thought. Later on, by appealing to her passions, and by carefully making use of those which could serve us, we might hope to obtain a kind of reaction on her intellect, and by degrees increase the insensible 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 towards 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, there was a fixed correlation between the sound and her taste, a correspondence between 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 on the face of the clock.
"It was impossible for me for a long time to attract her attention to the hands, but I succeeded in making her remark the clockwork and the striking apparatus. The means I employed were very simple; I asked them not to have the bell rung for lunch, and everybody got up and went into the dining room, when the little brass hammer struck twelve o'clock, but I found great difficulty in making her learn to count the strokes. She ran to the door each time she heard the clock strike, but by degrees she learned that all the strokes had not the same value as far as regarded meals, and she frequently fixed her eyes, guided by her ears, on the dial of the clock.
"When I noticed that, I took care, every day at twelve and at six o'clock to place my fingers on the figures twelve and six, as soon as the moment she was waiting for, had arrived, and I soon noticed that she attentively followed the motion of the small brass hands, which I had often turned in her presence.
"She had understood! Perhaps I ought rather to say that she had seized the idea. I had succeeded in getting the knowledge, or rather the sensation of the time into her, just as is the case with carp, who certainly have no clocks, when they are fed every day exactly at the same time.
"When once I had obtained that result, all the clocks and watches in the house occupied her attention almost exclusively. She spent her time in looking at them, in listening to them and in waiting for meal times, and once something very funny happened. The striking apparatus of a pretty little Louis XVI. clock that hung at the head of her bed, having got out of order, she noticed it. She sat for twenty minutes, with her eyes on the hands, waiting for it to strike ten, but when the hand passed the figure, she was astonished at not hearing anything; so stupefied was she, indeed, that she sat down, no doubt overwhelmed by a feeling of violent emotion, such as attacks us in the face of some terrible catastrophe. And she had the wonderful patience to wait until eleven o'clock, in order to see what would happen, and as she naturally heard nothing, she was suddenly either seized with a wild fit of rage at having been deceived, and imposed upon by appearances, or else overcome by that fear which some frightened creature feels at some terrible mystery, and by the furious impatience of a passionate individual who meets with some obstacle, she took up the tongs from the fireplace and struck the clock so violently that she broke it to pieces in a moment.
