drawn only once,
although it is the same throughout. The numbers 18, 290 and 261 are the
numbers of the ultimate physical atoms found to exist in a chemical atom.

The dots indicate the lines along which force is observed to be playing,
and the arrowheads show the direction of the force. No attempt has been
made to show this below E 2 except in the case of the hydrogen. The letters
given are intended to help the reader to trace upwards any special body;
thus _d_ in the oxygen chemical atom on the gas level may be found again on
E 4, E 3, and E 2. It must be remembered that the bodies shown
diagrammatically in no way indicate relative size; as a body is raised from
one substate to the one immediately above it, it is enormously magnified
for the purpose of investigation, and the ultimate atom on E 1 is
represented by the dot _a_ on the gaseous level.

The first chemical atom selected for this examination was an atom of
hydrogen (H). On looking carefully at it, it was seen to consist of six
small bodies, contained in an egg-like form. It rotated with great rapidity
on its own axis, vibrating at the same time, and the internal bodies
performed similar gyrations. The whole atom spins and quivers, and has to
be steadied before exact observation is possible. The six little bodies are
arranged in two sets of three, forming two triangles that are not
interchangeable, but are related to each other as object and image. (The
lines in the diagram of it on the gaseous sub-plane are not lines of force,
but show the two triangles; on a plane surface the interpenetration of the
triangles cannot be clearly indicated.) Further, the six bodies are not all
alike; they each contain three smaller bodies--each of these being an
ultimate physical atom--but in two of them the three atoms are arranged in
a line, while in the remaining four they are arranged in a triangle.

The wall of the limiting spheroid in which the bodies are enclosed being
composed of the matter of the third, or gaseous, kind, drops away when the
gaseous atom is raised to the next level, and the six bodies are set free.
They at once re-arrange themselves in two triangles, each enclosed by a
limiting sphere; the two marked _b_ in the diagram unite with one of those
marked _b'_ to form a body which shows a positive character, the remaining
three forming a second body negative in type. These form the hydrogen
particles of the lowest plane of ether, marked E 4--ether 4--on the
