mpounds.

In the hyper-condition, the connexion between the double triplets is
broken, and they become four independent groups, two like ix, in the
hyper-types (p. 25), and two remaining linear, but rearranging their
internal relations; the two remaining groups break up into two pairs and a
unit.

The final dissociation sets all the atoms free.

OCCULTUM (Plate VI, 1).

[Illustration]

On the first dissociation of the component parts of occultum, the
tetrahedron separates as a whole, with its four "cigars," flattening itself
out within its hole, _a_; two "cigars" are positive and two negative,
marked respectively _a_ and _a'_. The rope becomes a ring within a sphere,
_b_, and the two bodies _d_ _d_, which are loose in the gaseous atom, come
within this ring. The balloon becomes a sphere.

On further dissociation, the "cigars" go off independently, showing two
types, and these again each divide into triplets, as meta-compounds. _B_,
on the meta-level, casts out the two _d_ bodies, which become independent
triplets, and the "rope" breaks into two, a close ring of seven atoms and a
double cross of eight. These subdivide again to form hyper-compounds, the
ring yielding a quintet and a pair, and the double cross separating into
its two parts.

The balloon, _c_, becomes much divided, the cohesion of its parts being
slight; it forms two triplets, a pair and a unit, and these set free, on
further dissociation, no less than five separate atoms and two duads.

The two triplets of _d_ each cast out an atom on dissociation, and form two
pairs and two units.

SODIUM (Plate VI, 2).

It is convenient to consider sodium next, because it is the basic pattern
on which not only copper, silver and gold are formed, but also chlorine,
bromine and iodine.

[Illustration]

When sodium is set free from its gaseous condition, it divides up into
thirty-one bodies--twenty-four separate funnels, four bodies derived from
the two central globes, and three from the connecting rod. The funnels
become spheres, and each contains four enclosed spheres, with more or less
complicated contents. Each central globe yields a sextet and a quartet, and
the rod sets free two quartets and a peculiarly formed sextet.

When the proto-compounds are dissociated, the funnel-sphere sets free: (1)
the contents of _a_, rearranged into two groups of four within a common
sphere; the sphere yields four duads as hyper-compounds; (2) the contents
of _b_, which
