tends greatly to rivet the attention, and deepen the interest of the
hearer, as well as to heighten the effect, and enforce the importance of
the sentiments delivered. To the eyes belong the effusion of tears, and to
give way to this proof of feeling should not be called a mark of weakness,
but rather a proof of sensibility, which is the test of sincerity.

Next to the eyes, the mouth is the most expressive part of the countenance.
"The Mouth," says Cresallius, "is the vestibule of the soul, the door of
eloquence, and the place in which the thoughts hold their highest debates."
It is the seat of grace and sweetness; smiles and good temper play around
it; composure calms it; and discretion keeps the door of its lips. Every
bad habit defaces the soft beauty of the mouth, and leaves indelible traces
of its injury, they should, therefore, be carefully avoided. The motion of
the lips should be moderate, to moisten them by thrusting the tongue
between them is very disagreeable, and biting the lips is equally
unbecoming. We should speak with the mouth, more than with the lips.

Unless the pupil is very careful, he will find some difficulty in keeping
the mouth sufficiently wide open, he will gradually close the mouth until
the teeth are brought nearly together, before the sound is finished, the
inevitable consequence of which is a smothered, imperfect and lifeless
utterance of the syllable or word. A good opening of the mouth is
absolutely indispensable in giving the voice the full effect of round,
smooth and agreeable tone.
