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
