To close the hand and place the thumb outside upon the index finger, signifies conflict. This is the concentro-concentric hand.

To bend the first joint with the fingers somewhat apart, indicates the eccentro-concentric hand. This is the convulsive state.

Let us pass on to the eccentric genus.

The fingers somewhat spread, denote the normo-eccentric hand. This is exaltation.

To spread the fingers and fold them to the second joint, indicates the concentro-concentric hand. This is retraction.

To spread the fingers as much as possible, gives the eccentro-eccentric hand. This is exasperation.

In the subjoined charts we can see an illustration of the different attitudes of the hand.
