lar contractions as if the mastery of the
hypoglossus were not as yet complete. Quite similar fibrillar movements
seem to be made by the tongue in bulbar paralysis, and in the case of
dogs and guinea-pigs whose hypoglossus has been severed.

To the number of words heard that already produce a definite movement
are added the following new ones. The child is asked, "Where is the
moon? the clock? the eye? the nose?" and he raises an arm, spreads the
fingers, and looks in the proper direction. If I speak of "coughing," he
coughs; of "blowing," he blows; of "kicking," he stretches out his legs;
of "light," he blows into the air, or, if there is a lamp in sight,
toward that, looking at it meantime--a reminiscence of the blowing out
of matches and candles often seen by him. It requires great pains to get
from him the affirmative nod of the head at the spoken "ja, ja." Not
till the sixty-fourth week was this achieved by means of frequent
repetition and forcible direction, and the movement was but awkwardly
executed even later--months after. On hearing the "no, no," the negative
shake of the head now appeared almost invariably, and this was executed
as by adults without the least uncertainty.

The holding out of his hand at hearing "Give the hand," occurs almost
invariably, but is not to be regarded as a special case of understanding
of the syllable "give," for the word "hand" alone produces the same
result.

All these accomplishments, attained by regular training, do not afford
the least evidence of an understanding of what is commanded when the
sound-impression is converted into motor impulse. It is rather a matter
of the establishment of the recollection of the customary association of
both during the interval of deliberation. The words and muscular
contractions that belong together are less often confounded, and the
physiological part of the process takes less time, but its duration is
noticeably prolonged when the child is not quite well. He deliberates
for as much as twelve seconds when the question is asked him, "Where is
the rogue?" and then responds with the proper gesture (p. 115).

The sixteenth month brought few new articulate utterances of sound, none
associated with a definite meaning; on the other hand, there was a
marked progress in repeating what was said to the child, and especially
in the understanding of words heard.

Among the sounds of his own making are heard--along with the _hae!_
_hae-oe!_ _ha-[)e]!
