in place of the top sphere; the forms here are somewhat unusual, and the
triangles of the sextet revolve round each other on the meta level; all the
triads break up on the hyper level into duads and units.

FLUORINE (Plate IV, 3, and Plate XVII, 1).

The reversed funnels of fluorine split asunder on the proto level, and are
set free, the "balloons" also floating off independently. The funnels, as
usual, become spheres, and on the meta level set free their contained
bodies, three quartets and a triplet from each of the eight. The balloons
disintegrate in the usual way.

MANGANESE (Plate XVII, 2).

Manganese offers us nothing new, being composed of "lithium spikes" and
"nitrogen balloons."

VI.--THE STAR GROUPS.

We have now reached the last of the groups as arranged on Sir William
Crookes' lemniscates, that forming the "neutral" column; it is headed by
helium, which is _sui generis_. The remainder are in the form of a flat
star (see Plate IV, 4), with a centre formed of five intersecting and
"cigar"-bearing tetrahedra, and six radiating arms. Ten of these have been
observed, five pairs in which the second member differs but slightly from
the first; they are: Neon, Meta-neon; Argon, Metargon; Krypton,
