impatience, by screaming in vowels
which pass over into one another.

The only word that is unquestionably used of the child's own motion to
indicate a class of perceptions is still _atta_, _ha-atta_, which during
the following month also is uttered softly, for the most part, on going
out, and which signifies "away" or "gone" (weg), and still continues to
be used also as it was in the eleventh month, when a light is dimmed (by
a lamp-shade). Beyond this no syllable can be named that marked the dawn
of mental independence, none that testified to the voluntary use of
articulate sounds for the purpose of announcing perceptions. For the
_brrr_, the frequent _dakkn_, _mamam_, _moemoe_, and _papap_, are without
significance in the monologues. Even the saying of _atta_, with turning
of the head toward the person going away, has acquired the meaning of
"away" (fort) only through being repeatedly said to the child upon his
being carried out; but no one said the word when the lamp was
extinguished. Here has been in existence for some time not only the
formation of the concept, but also the designation of the concept by
syllables. The similarity in the very different phenomena of going away
and of the dimming of the light, viz., the disappearance of a visual
impression, was not only discovered, but was named by the child entirely
independently in the eleventh month, and has kept its name up to the
present time. He has many impressions; he perceives, he unites qualities
to make concepts. This he has been doing for a long time without words;
but only in this _one_ instance does the child express one of his
concepts in language after a particular instance had been thus named for
him, and then the word he uses is one not belonging to his later
language, but one that belongs to all children the world over.

In regard to the repeating of syllables pronounced to him a marked
advance is noticeable. The child can not, indeed, by any means repeat
_na_ and _pa_ and _o_ or _e_ and _be_. He answers _a_, _tai_,
_ta-a-o-oe-a_, and practices all sorts of tongue-and lip-exercises. But
the other syllables uttered by him, especially _anna_, _tai_, _dakkn_,
_a_, he says in response to any one who speaks them distinctly to him,
and he gives them easily and correctly in parrot fashion. If a new word
is said to him, e. g., "kalt" (cold), which he can not repeat, he
becomes vexed, turns away his head, and screams, too, sometimes. I have
been able to int
