nly _oerroe_ is distinctly repeated in
the tenth week. On the seventy-first day, the child being in the most
comfortable condition, there comes the new combination, _ra-a-ao_, and,
five days later, in a hungry and uncomfortable mood, _nae_, and then
_n[=a]i-n_.

The manifest sign of contentment was very distinct (on the
seventy-eighth day): _habu_, and likewise in the twelfth week _a-i_ and
_u[=a]o_, as well as _ae-o-a_, alternating with _ae-a-a_, and _o-ae-oe_.

It now became more and more difficult to represent by letters the
sounds, already more varied, and even to distinguish the vowels and
repeat them accurately. The child cries a good deal, as if to exercise
his respiratory muscles. To the sounds uttered while the child is lying
comfortably are added in the fourteenth week _ntoe_, _ha_. The last was
given with an unusually loud cry, with distinct aspiration of the _h_,
though with no indication that the child felt any particular pleasure.
At this period I heard besides repeatedly _loe_, _na_, the latter along
with screaming at disagreeable impressions more and more frequently and
distinctly; in the fifteenth week, _nannana_, _n[=a]-n[=a]_, _nanna_ in
refusal. On the other hand, the earlier favorite _oerroe_ has not been
heard at all for some weeks.

Screaming while waiting for his food to be prepared (milk and water)
or for the nurse, who had not sufficient nourishment for the child,
is marked, in the sixteenth week--as is also screaming on account
of unpleasant feelings--in general by predominance of the vowels,
_ae-[)u]_, _ae-[)u] ae_, _[=a]-[)u]_, _[=a]-[)u]_, _[)u]-ae_, _[)u]-ae_,
_[=u]-[=u]-[=a]-oe_, but meantime is heard _amme-a_, and as a sign
of special discomfort the persistent ill-sounding
_[=u][)a]-[=u][)a]-[=u][)a]-[=u][)a]_ (_[)u]_ = Eng. _[=oo]_).

Screaming in the first five months expresses itself in the main by the
vowels _u_, _ae_, _oe_, _a_, with _ue_ and _o_ occurring more seldom, and
without other consonants, for the most part, than _m_.

In the fifth month no new consonants were developed except _k_; but a
merely passive _goe_, _koe_, _aggegg[)e]koe_, the last more rarely than the
first, was heard with perfect distinctness during the child's yawning.

While in this case the _g_-sound originates passively, it was produced,
in connection with _oe_, evidently by the position of the tongue, when
the child was in a contented frame, as happens in nursing; _oegoe_ was
heard in the twenty-secon
