s the exciting and stimulating
medium of all the activities, energies, and motions of all Matter. Thus
the Aether is both universal and infinite in its extent.

Clerk Maxwell, in his paper on "Action at a Distance" (_Collected
Works_, by Niven), with reference to the universality of the Aether,
writes: "The vast interplanetary and interstellar regions will no longer
be regarded as waste places in the universe, which the Creator has not
seen fit to fill with the symbols of the manifold order of His Kingdom.
We shall find them to be full of this wonderful medium, so full, that no
human power can remove it from the smallest portion of space, or
produce the slightest flaw in its infinite continuity. It extends
unbroken from star to star, and when a molecule of hydrogen vibrates in
the Dog Star, the medium receives the impulses of those vibrations, and
transmits them to distant worlds. But the medium has other functions
besides bearing light from world to world, and giving evidence of the
absolute unity of the material system of the universe. Its minute parts
may have rotatory as well as vibratory motions, and the axes of rotation
form those lines of magnetic force which extend in unbroken continuity
into regions which no eye has seen, and which, by their action on our
magnets, are telling us in language not yet interpreted what is going on
in the hidden world from century to century." Now I premise, that in the
theory of the Aether to be submitted in this work, the physical
interpretation of this statement of Maxwell's will receive its literal
fulfilment.

ART. 44. _Aether is Atomic._--If there is one fundamental truth which is
applicable to all matter, it is, that all matter is atomic.

Professor Rucker, in his Presidential Address to the British Association
of 1901, in dealing with this question, said: "The believer in the
atomic theory asserts that matter exists in a particular state, that it
consists of parts which are separate and distinct from one another, and
as such are capable of independent movement. It is certain that matter
consists of discrete parts in a state of motion, which can penetrate
into spaces between the corresponding parts of surrounding bodies. Every
great advance in chemical knowledge during the last ninety years finds
its interpretation in Dalton's Atomic Theory."

From such an authority as this, and from the facts which he gave in his
dealing with the question, we are bound to admit that all
