How far the power of imitation and of articulation is developed, is shown especially by the fact that now, at last, _pa_ is correctly pronounced in response; in the beginning _ta_ was still frequently the utterance, then _ba_, finally _pa_ almost invariably given correctly. Further, these results were obtained: Words said to him. Response. bitte _bis_, _bits_, _bit_, _bets_, _beest_, _be_, _bi_, _bit-th_ (Eng., _th_). hart _hatt_, _att_, _haat_. Fleisch _da-ich_, _dai-s-ch_, _dai-s-j_. ma _moe_, _ma_. In _bits_ appears with perfect distinctness (as already in the fifteenth month) the very rare _ts_ = _z_. The "hart" was once only confounded with "haar," and responded to by grasping at the hair. The _bits_ soon served to add force to the putting together of the hands in the attitude of begging; it is thus the first attempt at the employment of a German word to denote a state of his own, and that the state of desire. The other words said to him, and illustrated by touching and putting the hands upon objects, could not be given by him in response. When he was to say "weich" (soft), "kalt" (cold), "nass" (wet), he turned his head away in repugnance, as formerly. To "nass" he uttered in reply, once only, _na_. Smacking, when made for him, was imitated perfectly. The early morning hours, in which the sensibility of the brain is at its highest, are the best adapted to such experiments; but these experiments were not multiplied, in order that the independent development might not be disturbed. The progress in the discrimination of words heard, and in the firm retention of what has been repeatedly heard, is shown particularly in more prompt obedience, whether in abstaining or in acting. To the list of objects correctly pointed out upon request are added "leg, nail, spoon, kettle," and others. It is noteworthy, too, that now, if the syllables _pa_ and _ma_, or _papa_ and _mamma_, are prefixed to the names of the known parts of the face and head, the child points these out correctly; e. g., to the question "Where is Mamma-ear," the child responds by taking hold of the ear of his mother, and to "papa-ear," of that of his father; so with "nose, eye," etc. But if asked for "mamma-beard," the child is visibly embarrassed, and finally, when there is a laugh at his hesitation, he laughs too.
