What was in the little mind? Was she beginning to discriminate and compare, for the first time setting apart as two separate things the two faces that had bent over her oftenest? Or was she simply using, on the most convenient object, a new power of adjusting her eyes, which filled her with serious interest by the new clearness it gave to what she saw? At all events, she would not have looked from one to the other with such long and attentive regard if she had not been able to focus both faces, at their different distances; so that I felt sure the power of accommodation was really there. But there was more in the incident than just the advance in vision. Hitherto when the baby had turned her head to look, it had been only at something that she had already a glimpse of, off at the edge of the field of vision. Now she turned to look for something quite out of sight,--something, therefore, that must have been present as an _idea_ in the little mind, or she could not have looked for it. And in view of what I have said of the mother’s face as the great educational appliance in the early months, it is worth noticing that it was this which gave the baby her first idea, so far as I could detect. We come a step nearer, too, to true memory, when the baby can keep thus, even for a few minutes, the idea of something formerly seen. It was still mainly habit memory, however. She looked for an accustomed sight in an accustomed place, bringing it to the point of clear vision by an accustomed movement of the neck muscles. There was no evidence till considerably later that she was capable of remembering a single, special experience. The next day she was singularly bright and sunny, smiling all day at every one. She stopped in the middle of nursing to throw her head back and gaze at the bow at her mother’s neck, and would not go on with the comparatively uninteresting business of food till the bow was put out of sight. That night she slept eight hours at a stretch, longer than she had ever done. Was the little brain, perhaps, wearied with the new rush of impressions, which came with the new power of focusing? The day after she would lie a while unusually silent and sober, looking about her and moving her hands a little; then she would fret to be lifted and held against one’s shoulder, where she could hold her head up and look about. She was able now to hold it up a long time by resting it for a few seconds every half minute or so, against my cheek, which I held close to give her the chance. But to-day she was not satisfied with having her head erect: she persistently straightened her back up against the arm that supported her--a new set of muscles thus coming under control of her will. As often as I pressed her down against my shoulder, she would fret, and straighten up again and set to work diligently looking about her.
