ut
spreading or folding the fingers, we shall have that attitude which
signifies abandon.

Let us now take the eccentric species, still in the normal genus.

Raise the hand somewhat with a slight parting of the fingers, and we
have the eccentro-normal hand, which signifies expansion.

Finally, let us consider the concentric species, still in the normal
state.

Present the hand lifeless and you have the concentro-normal attitude,
which signifies prostration.

Let us pass on to the concentric genus.

By closing the fingers with the thumb inward upon the middle one, we
shall have the normo-concentric hand, which signifies the _tonic_ or
power.

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.

Recapitulation

II +-- 2 +-- Concentro-concentric. Conflict.
| 3 --+ Normo-concentric. Tonic or power.
| 1 +-- Eccentro-concentric. Convulsive.
|
| 2 +-- Concentro-normal. Prostration.
III --+ 3 --+ Normo-normal. Abandon.
| 1 +-- Eccentro-normal. Expansion.
|
| 2 +-- Concentro-eccentric. Retraction.
| 3 --+ Normo-eccentric. Exaltation.
I +-- 1 +-- Eccentro-eccentric. Exasperation.

The nine primitive forms of the hand are, as is seen, undetermined.
