we are now dealing
with) "between two electrified bodies is equal to the quantities of
electricity with which the body is charged." This law was established
and proved by Coulomb by means of a delicate instrument known as the
Torsion Balance, with which he also established the law of inverse
squares.

It will be seen at a glance that there is a slight difference between
stating the law of proportion with reference to the centripetal force,
and the centrifugal force or motion. In the former we state the
proportion is equal to the product of the masses, while in the latter we
say that the proportion is equal to the product of the quantities of
electricity.

In the one case we deal with the mass of the body, whether it be atom,
molecule, planet or star; in the other case we deal with quantities of
electricity. At first sight it may seem that there is little, if any,
connection between the two laws, but a careful reflection of the
hypotheses laid down with regard to the aetherial medium will show that
there is not only a close connection between these two laws of
proportion, but also that the law governing the repulsive power of the
aetherial electric waves is the direct outcome of the law of proportion
governing the centripetal force. Let us restate our case in regard to
the aetherial medium.

We have learned that the Aether is gravitative, and that it also has an
electro-magnetic basis is proved from Maxwell's electro-magnetic theory
of light. Let me ask the reader this question therefore. If the Aether
be gravitative, what must be the rule governing the extent and density
of the aetherial atmosphere surrounding any planet or sun or other body?
If the Law of Gravity teaches us anything at all, it distinctly teaches
us that the gravitating power of any body is regulated by the mass of
the body, as the law states that the attraction is proportionate to the
product of the masses. It states nothing about volume or condition of a
body.

The exact size or state of a body has no direct result bearing on
gravitation attraction; the underlying principle being that the
attractive force is dependent on the mass, and only on the mass of a
body. So that if the volume of any body, whether atom, planet, satellite
or sun, be doubled, its attractive power remains the same, simply
because the mass of the whole body remains the same. Mass, we are told
by mathematicians, is equal to the volume multiplied by the density, and
whenever w
