The best effect is produced by letting the motion of the hand start from
the left and end on the right, but this must be done
gently, the hand sinking to rest and avoiding all
appearance of giving a blow, although at the end of
a sentence it may sometimes be allowed to drop, but
must quickly be raised again: or it may occasionally,
when we desire to express wonder or dissent, spring
back with a rapid motion.
In this connexion the earlier instructors in the art
of gesture rightly added that the movement of the
hand should begin: and end with the thought that is
expressed. Otherwise the gesture will anticipate or
lag behind the voice, both of which produce an
unpleasing effect.
