Sometimes we may hold the first two fingers apart without, however, inserting the thumb between them, the remaining two pointing inwards, while even the two former must not be fully extended.

Sometimes, again, the third and little finger may be pressed in to the palm near the base of the thumb, which in its turn is pressed against the middle joints of the first and middle fingers; at others the little finger is sometimes drooped obliquely, or the four fingers may be relaxed rather than extended and the thumb slanted inwards: this last gesture is well adapted to pointing to one side or marking the different points which we are making, the had being carried palmupwards to the left and swept back to the right face-downwards.

The following short gestures are also employed: the hand may be slightly hollowed as it is when persons are making a vow, and then moved slightly to and fro, the shoulders swaying gently in unison: this is adapted to passages where we speak with restraint and almost with timidity. Wonder is best expressed as follows: the hand turns slightly upwards and the fingers are brought in to the palm, one after the other, beginning with the little finger; the hand is then opened and turned round by a reversal of this motion.

There are various methods of expressing interrogation; but, as a rule, we do so by a turn of the hand, the arrangement of the fingers being indifferent. If the first finger touch the middle of the right-hand edge of the thumb-nail with its extremity, the other fingers being relaxed, we shall have a graceful gesture well suited to express approval or to accompany statements of facts, and to mark the distinction between our different points.

There is another gesture not unlike

the preceding, in which the remaining three fingers are folded: it is much employed by the Greeks both for the left hand and the right, in rounding off their enthymemes, [*]( Rhetorical or incomplete syllogisms. But see V. x. 2. xiv. 1 ) detail by detail. A gentle movement of the hand expresses promise or assent, a more violent movement suggests exhortation or sometimes praise. There is also that familiar gesture by which we drive home our words, consisting in the rapid opening and shutting of the hand: but this is a common rather than an artistic gesture.
