string with a ball attached to one of the ends is held firmly by the
hand. An impulse or motion is imparted to the ball by the hand, that
motion being continued by the movement from the hand. The first impulse
given to the ball by the hand represents the Primitive Impulse. The
tension on the string which holds the ball to its controlling centre
represents the Centripetal Force, while the opposite force on the
string, which takes up the Primitive Impulse and continues it, is
represented by the Centrifugal Force.

The conception of the Centripetal Force is therefore simple, and
entirely in accordance with our experience as gathered from observation
and experiments. Both in the spheres of electricity, and magnetism, we
find a similar force acting, which tends towards the centre of the
attracting body, and therefore the Centripetal Force satisfies the first
two Rules of our Philosophy.

Further, it adequately accounts for certain distinctive phenomena which
occur through the Law of Gravitation, as, for example, the falling of
bodies to the earth, and therefore is entirely in harmony with all the
requirements of those principles enunciated by Newton for the successful
explanation of any phenomena. I need hardly point out, therefore, this
being so, any physical cause suggested as the explanation of Gravitation
must deal with the Centripetal Force, and be able to give a physical
explanation of the mode and manner in which the Centripetal Force
operates.

The Attraction of Gravitation or the Centripetal Force, however, being,
as its name implies, simply a drawing or pulling power to a centre, that
is, a force that is ever and ever only drawing matter to matter, or body
to body, it could not of, and by itself, accomplish those necessary
stellar and planetary motions by which are produced that universal
order, unity and harmony which characterize the universe. It is
essentially in its operations and influences, a one-sided force, ever
tending and influencing towards self, and therefore by itself would only
be a detriment and an evil; and, unless it were accompanied by some
companion or complementary and counter force, with which it acts in
union and concert, and which exactly counteracts its pulling power and
influence, it would soon draw star to star, and world to world, crashing
and heaping them together in ruinous and dire confusion. So that,
instead of the infinitude of worlds which now exist, which flash and
