If the movement ends toward the interlocutor, it is simple negation.

If the movement ends opposite to him, it is negation with distrust.

9.  The rotative and forward inflection would denote exaltation.

The sense of this response,—­“I do not know,” when tidings of a friend are asked, may be divined by an inflection of the head.

It is well to note how these movements are transmitted from agent to agent.

All movements which severally affect the head, the hand, the body and the leg, may affect the whole.

Thus the movement of negation is made by the hand.  This movement is double.  There is negation with direct resolution, and negation with inverse resolution, which is elliptical.  The hand recoils as the head recoils, and when the head makes the movement of impatience, the hand rises with the head and says:—­“Leave me alone, I do not wish to hear you.”

It is curious to see an inflection pass successively from the head to the hand, from the hand to the eye, from the eye to the shoulders, from the shoulders to the arms, from the arms to the legs, from the legs to the feet.

For example:  Above we have indicated a double menace made by the head.  One might transfer this menace to the hand and say:  “You will have a quarrel to settle with me!”

Each agent has its role, and this is why they transmit their movements.

When the head has a serious part to play, it communicates an inflective movement to the hand, which renders it terrible.

A man who menaces with the head is not sure of his aim, but he who menaces with the hand is sure of striking right.  In order to do this, the eye must be firmly fixed, as the eye necessarily loses its power and accuracy by a movement of the head.

There is great power in the menace communicated to the hand, a power not found in the other movement.  The head-menace is more physical, and the hand-menace more intellectual; in the one the eye says a great deal, while in the other it says nothing.

The orator cannot always make these gestures with facility.  The menace may be elliptical.  Then it must be made by the head, and expressed through the eyes.  This is why the speaker gazes downward as he makes it.

It is the same downward or upward movement which is reproduced when the menace is concentric or elliptical.

The menace may be made in yet another way.  The speaker does not wish to express his opinion, and for fear of compromising himself with his eyes, he does not gaze at his interlocutor; he turns aside his glance, and the menace is communicated to the shoulder.  This has less strength, because it is rendered by one of the sensitive agents.

The man who threatens with the shoulder is more passionate; but he is not the agent, he is passive.

A simple menace may be made by the knee.  The foot is susceptible of great mobility.  A slight movement quickly changes its significance; in passing from one agent to another, it is modified by many ellipses.
