an aetherial basis,
and are also due to certain kinds of motion in the Aether.

That motion may be rotatory motion or vibratory motion, as the case may
be, but whatever definition we give of electricity, we cannot as yet say
definitely that Aether is electricity.

We may assume, and indeed prove, that Aether has an electrical and
magnetic basis, in the same way that it has a thermal or heat basis, or
a luminiferous or light basis; but while we admit such a hypothesis, we
cannot admit as yet that Aether and electricity are one and the same
thing. It is not within the province of this work, however, to prove
what electricity is, or show the relation of Aether to all the various
forms of electricity with which we are conversant, but I think I may
venture to make this statement, that all forms of electricity, whether
it is electro-static, that is electricity at rest, or current
electricity, or electro-magnetism, are due to certain forms of motion
of the universal Aether, in the same way that light and heat are also
particular forms of motion of the same medium. I need hardly point out
that it is an absolute impossibility for me to deal with such a subject
as Electricity in all its details and various aspects in one chapter; so
that I shall have to assume that the reader is familiar with some of the
elementary truths of the subject.

At the same time, I will endeavour to make clear most of the technical
terms used as we proceed. From the Electro-Magnetic theory of light,
therefore, we learn that Aether has an electrical or electro-magnetic
basis, so that, wherever we get Aether, there we have the bases and
conditions which will produce all the phenomena with which we are
conversant in the sphere of electricity. Given the required motions in
the Aether necessary to produce any particular form of electricity, then
that form is produced as soon as the motions of the Aether are generated
by any charged or electrified body. Produce a circular current in any
way in the Aether, and you will have a circular current of electricity;
produce radiations from a radiating body, and you will get electric
radiations which speed away with the velocity of light.

This phase of the Aether is entirely in harmony with Dr. Larmor's
Hypothesis of Electrons, which has already been referred to in Art. 44.
Dr. Larmor in his work indicates that electricity has an atomic basis,
and further states that "the atomicity of electricity is coming within
