g of the types which form the
object of the system. It offers us a knowledge of the formal or
constitutional types, of the fugitive or accidental types, and, finally,
of the habitual types.

The triple object of the dynamic are the _rhythmic, inflective_ and
_harmonic_ forms. Dynamic rhythm is founded upon the important law of
mobility, inversely proportionate to the masses moved. Dynamic
inflections are produced by three movements: Direct movements, rotary
movements and movements of flexion in the arc of a circle.

Dynamic harmony is founded on the concomitance of the relations existing
between all the agents of gesture. This harmony is regulated by three
states, namely: The tonic or eccentric state, the atonic or concentric
state, and the normal state. It, therefore, remains for us to fix the
three vital conditions of the static part of gesture. The vital
condition of the static is based upon the knowledge of the nine
stations. The spirit of the static entails the study of scenic planes
which embrace three conditions: The condition of the personage in
relation to the scenic centre or to the interlocutor whom he addresses;
in the second place, his situation; and, finally, the direction assumed
by his body in regard to the conditions already indicated.

The soul of the static is in the harmonic opposition of the surfaces
moved.

The most powerful of all gestures is that which affects the spectator
without his knowing it.

From this statement may be deduced the principle that: Outward gesture,
being only the echo of the inward gesture which gave birth to it and
rules it, should be inferior to it in development and should be in some
sort diaphanous.

Attitudes of the Head.

The head, considered in its three direct poses, presents three
conditions or states. When facing the object contemplated, it presents
the normal state; bent forward and in the direction of the object, it
presents the concentric state; raised and considering the object from
above, it presents the eccentric state. [Compare Delaumosne, page 65.]

If, now, we consider each of its attitudes in connection with a double
lateral inclination of which they are capable, we have the following
nine:

1. The first is normal. The head is neither high nor low, the glance
being direct.

2. The second is characteristic of tenderness. This attitude consists in
bending the head obliquely toward the interlocutor. The body, in this
attitude, should n
