l communication, in contrast with the
loud-sounding reflex movements of sneezing and of hiccough, and with the
infrequent snoring, snuffling (in sucking), and other loud expirations
observed in the first days, which have just as little linguistic value
as have coughing and the later clearing of the throat.

The voice is very powerful as early as the sixth day, especially when it
announces feelings of discomfort. Screaming is much more frequent,
persistent, and vigorous also when diluted cow's milk is given instead
of that from the breast. If one occupies himself longer than usual with
the infant (in the first two months), the child is afterward more
inclined to cry, and cries then (as in the case of hunger) quite
differently from what he does when giving notice of something
unpleasant--e. g., wetness. Directly upon his being made dry, the crying
ceases, as now a certain contentment is attained. On the other hand, the
inclination to cry serves very early (certainly from the tenth week on)
as a sign of well-being (or increase in the growth of the muscles). At
least a prolonged silence at this season is wont to be connected with
slight ailment. But it is to be remarked that during the whole period no
serious illness, lasting more than one day, occurred.

On the forty-third day I heard the _first consonant_. The child, in a
most comfortable posture, uttering all sorts of obscure sounds, said
once distinctly _am-ma_. Of vowels, _ao_ was likewise heard on that day.
But, on the following day, the child surprised me and others by the
syllables, spoken with perfect distinctness, _ta-hu_.

On the forty-sixth day, in the otherwise unintelligible babble of the
infant, I heard, once each, _goe_ (_oe_ nearly like _i_ in bird), _oeroe_,
and, five days later, _ara_.

In the eighth and ninth _weeks_, the two utterances, _oerroe_, _arra_,
became frequent, the _oe_ and _a_ being pure and the _r_ uvular.

The syllable _ma_ I heard by itself (it was during his crying) for the
first time on the sixty-fourth day. But on the following day was
sounded, during persistent, loud crying, often and distinctly (it
returned in like manner months after), _nei_, _nei_, _nei_, and once,
during his babbling, _a-omb_.

On the day after, distinctly, once each, _la_, _grei_, _aho_, and,
besides, _ma_ again.

On the sixty-ninth day, the child, when hungry, uttered repeatedly and
very distinctly, _moemm_ and _ngoe_.

Of the syllables earlier spoken, o
