make up even a short speech is therefore enormous, and these movements
and sequences of movement occur rarely, and at intervals that are ex-
tremely irregular.
It is important to note here that the three sets of neuro-muscular
mechanisms mentioned above are not of the same order. The organs of
respiration are the most central or fundamental of the series. The
organs of phonation, which give vocal character to the stream of expired
air from the lungs, are intermediate, and their neural mechanisms are,
;herefore, to be considered as accessory in comparison with those of the
sreathing organs, but relatively fundamental in comparison with the
senters which represent the movements of the more peripheral organs
of articulation. It is indisputably certain that the young child learns to
hreathe and cry aloud before it can speak, and that there is a progressive
development in his power to imitate and reproduce the consonant sounds,
after he has begun to speak. It seems to me that we may safely aver
that the law of the evolution of the nervous system is of great pedagogical
importance, since it suggests the natural order which should be followed
in training the organs concerned in any complex co-ordinated move-
ments. For instance, it is transgressing the laws of nature to emphasize
the training of the fingers before the neuro-muscular mechanisms of the
hand, arm, and shoulder have become thoroughly organized, and their
respective movements been brought under control; or to attempt to teach
a child to read aloud before he has learned to speak plainly and readily.
Dr. H. Gutzmann declares that in fully half of the children who enter
school the power of speech is undeveloped.
Dr. Ross has criticised the tendency to follow an inverted or unnatural
order in education, as follows : ¢¢ Until a few years ago the natural order
of development was reversed in the education of youth, and especially in
female education, so far as this could be accomplished by human contriv-
ance and ingenuity. . . . No sooner had what is technically called
aducation begun than the professional trainer began to exercise the small
muscles of vocalization and articulation, so as to acquire the art of reading;
she small muscles of the hand, so as to acquire the art of writing ; and, in
she case of young ladies, the still more complicated movements necessary
in running over the keyboard of the piano; while little attention was
paid to the development of the larger muscles of the trunk and lower
axtremities, upon the full development of which the future comfort of
she individual depends.”
Stuttering is generally recognized now, by all competent persons, as a
neurosis or functional disorder of one or another of the neuro-muscular
mechanisms concerned in vocal utterance. Professor Kussmaul, of Stras-
burg, whose book, ¢“Die Stérungen der Sprache,” deservedly enjoys the
highest reputation, defines it as follows—I quote from the English transla-
jon of Ziemsen’s ¢¢ Cvelopedia.” vol. xiv. : ¢“ Stuttering is a spasmodic neu-
