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
