_one_ kind of _consonant_ sounds is made. If the _breath_ is driven out
_without voice_, and is held back by these same parts of the mouth, the
_other_ kind of _consonant_ sounds is formed. Ex. of both: _b, d, g; p, t,
k_.

The teacher and pupils should practice on these sounds till the three kinds
can easily be distinguished.

You are now prepared to understand what I mean when I say that the +vowels+
are the +letters+ which stand for the +open sounds of the voice+, and that
the +consonants+ are the +letters+ which stand for the sounds made by the
+obstructed voice+ and the +obstructed breath+.

The teacher can here profitably spend a few minutes in showing how ideas
may be communicated by _Natural Language_, the language of _sighs, groans,
gestures_ of the hands, _attitudes_ of the body, _expressions_ of the face,
_tones_ of the voice, etc. He can show that, in conversation, we sometimes
couple this _Natural Language_ of _tone_ and _gesture_ with our language of
words, in order to make a stronger impression. Let the pupil be told that,
if the passage contain feeling, he should do the same in _Reading_ and
_Declaiming_.

Let the following definitions be learned, and given at the next recitation.

+DEFINITION.--Artificial Language, or _Language Proper_, consists of the
spoken and written words used to communicate ideas and thoughts+.

+DEFINITION.--_English Grammar_ is the science which teaches the forms,
uses, and relations of the words of the English Language+.
