The convex eccentric chest is the sign of the agent, or of him who gives.
The convex concentric chest or the pathetic, is the sign of the sufferer, or of him who receives.
The chest drawn in with the shoulders elevated, is the expression of the sublime.
From these three positions, the eccentric, the concentric and the normal, are derived nine degrees or species. Thus in each of these genera, the torso is inclined toward the speaker, or away from him, hence we have three times three, or nine, or the triple accord.
The chest need not be lowered; it is here that all the energy concentrates.
The Shoulders.--Every sensitive, agreeable or painful form is expressed by an elevation of the shoulders. The shoulders are the thermometer of the sensitive and passional life. If a man's shoulders are raised very decidedly, we may know that he is decidedly impressed.
The head tells us whether this impression is joyous or sorrowful. Then the species belongs to the head, and the genus to the shoulder.
If the shoulder indicates thirty degrees, the head must say whether it is warmth or coldness. The face will specify the nature of the sorrow or joy whose value the shoulders have determined.
The shoulder is one of the great powers of the orator.
