of gravity to an atomic system, and a centre of
gravity to a planetary system, and a centre of gravity to a solar
system, then there is also a centre of gravity to a group of systems,
even to a constellation, or a galaxy; otherwise our philosophy relative
to the centres of gravity of masses fails in its application to wider
phenomena of an exactly similar kind.

Thus, if there is a centre of gravity to a galaxy, even to the Milky Way
itself, then, going one step further, with a faith that laughs at
scientific data and leaps beyond the narrow bounds of pure reasoning, we
affirm that there must even be a centre of gravity to the entire
Universe. Now let me ask the reader, What can be more fitting, more
appropriate, more reasonable than to infer that the centre of gravity of
the Universe is to be found in that celestial orb or orbs where the
throne of God exists and endures, and where ultimately there will be
congregated together in perfect felicity the spirits of just men made
perfect, not only from our insignificant planet, but all the spirits of
all beings from all the planets which in their almost infinite number
are circled round their central suns by the electro-magnetic Aether? It
is there, in these bright orbs, with their vision and powers
spiritualized, quickened and intensified, that all perfected spirits
shall look out into space, with increasing wonder, upon the birth and
decay of worlds, the evolution and devolution of planets and systems and
constellations, and shall watch the continuation and working out of that
grand and glorious plan, which alone finds its perfection and its
ultimate fulfilment in the wisdom, and power, and glory of the Eternal
Spirit of the Living God.

To see if this conception of the Universe is borne out by scientific
data, we will now address ourselves more particularly to those
fundamental truths which underlie the unity of the Universe.

ART. 124. _The Unity of the Universe._--The Unity of the Universe is a
dream which has passed before the imagination of many philosophers in
by-gone times, and has been a fruitful source of speculation to
old-world, as well as more modern philosophers. The researches of such
living scientists as Sir William Crookes, Professor J. J. Thomson and
others, have, however, made this dream come within the range of
practical research and direct experiment. Professor J. J. Thomson
believes that it is possible to break off from an atom, a part which is
