The sensitive, mental and moral state of man are rendered by the eccentric, concentric or normal form of the organism.[1]

Such is the first and greatest law.  There is a second law, which proceeds from the first and is similar to it: 

Each form of the organism becomes triple by borrowing the form of the two others.

It is in the application of these two laws that the entire practice of the art of oratory consists.  Here, then, is a science, for we possess a criterion with which all phenomena must agree, and which none can gainsay.  This criterion, composed of our double formula, we represent in a chart, whose explanation must be carefully studied.

The three primitive forms or genera which affect the organs are represented by the three transverse lines.

GENUS.                    SPECIES.
1           3            2

II.  Conc. 1-II 3-II 2-II
Ecc.  Conc.  Norm.  Conc.  Conc.  Conc.

III.  Norm. 1-III 3-III 2-III
Ecc.  Norm.  Norm.  Norm.  Conc.  Norm.

I. Ecc.          1-I          3-I          2-I
Ecc.  Ecc.     Norm.  Ecc.    Conc.  Ecc.

The subdivision of the three genera into nine species is noted in the three perpendicular columns.

Under the title Genus we shall use the Roman numerals I, III, II.

Under the title Species we employ the Arabic figures 1, 3, 2.

I designates the eccentric form, II the concentric form, III the normal form.

The Arabic figures have the same signification.

The normal form, either in the genus or the species, we place in the middle column, because it serves as a bond of union between the two others, as the moral state is the connecting link between the intellectual and vital states.

Thus the first law relative to the primitive forms of the organs is applied in the three transverse columns, and the second law relative to their compound forms is reproduced in the three vertical columns.

As may be easily proven, the eccentric genus produces three species of eccentric forms, marked in the three divisions of the lower transverse column.

Since the figure 1 represents the eccentric form, 1-I will designate the form of the highest degree of eccentricity, which we call eccentro-eccentric.

Since the figure 3 represents the normal form, the numbers 3-I will indicate the normo-eccentric form.

Since the figure 2 designates the form which translates intelligence, the figures 2-I indicate the concentro-eccentric form as a species.  As the species proceeds from the genus, we begin by naming the species in order to bring it back to the genus.  Thus, in the column of the eccentric genus the figure 1 is placed after the numbers 3 and 2, which belong to the species.  We must apply the same analysis to the transverse column of the normal genus, as also to that of the concentric genus.
