Of isolated vowels, _a_ only was correctly repeated on command. Of syllables, besides those of the previous month, _moe_ and _ma_; and here the child's excessive gayety over the success of the experiment is worthy of remark. He made the discovery that his parrot-like repetition was a fresh source of pleasure, yet he could not for several weeks repeat again the doubled syllables, but kept to the simple ones, or responded with all sorts of dissimilar ones, like _attob_, or said nothing. The syllable _ma_ was very often given back as _hoema_ and _hoemoe_; _pa_ was never given back, but, as had been the case previously, only _ta_ and _tai_ were the responses, made with great effort and attention, and the visible purpose of repeating correctly. To the word "danke," pronounced for him with urgency innumerable times, the response is _dakkn_, given regularly and promptly, and this in the following months also. If all persuasion failed, and the child were then left to himself without any direction of his attention, then not infrequently new imitations of sounds would be given correctly--e. g., when I said "bo"--but these, again, would no longer succeed when called for. Indeed, such attempts often broke down utterly at once. Thus the child once heard a hen making a piteous outcry, without seeing the creature, and he tried in vain to imitate the sound, but once only, and not again. On the other hand, he often succeeds in repeating correctly movements of the tongue made for him to see, as the thrusting out of the tongue between the lips, by reason of the extraordinary mobility of his tongue and lips; he even tries to smack in imitation. The more frequent partial contractions of the tongue, without attempts at speaking, are especially surprising. On one side, toward the middle of the tongue, rises a longitudinal swelling; then the edges are brought together, so that the tongue almost forms a closed tube; again, it is turned completely back in front. Such flexibility as this hardly belongs to the tongue of any adult. Besides, the lips are often protruded a good deal, even when this is not required in framing vocables.
