Here we have some new combinations, which recur persistently in its allies. The bodies a, in Plate XIX, 1, are at the top and bottom of the ellipse; they come to right and left of it in the proto state, and each makes a twelve-atomed body on the meta level.
The five bodies within the ellipse, three monads and two sextets, show two which we have had before: d, which behaves like the quintet and quartet in silicon, after their junction, and b, which we have had in iron. The two bodies c are a variant of the square-based pyramid, one atom at the apex, and two at each of the other angles. The globe, e, is a new form, the four tetrahedra of the proto level making a single twelve-atomed one on the meta. The body a splits up into triplets on the hyper; b and d follow their iron and silicon models; c yields four duads and a unit; e breaks into four quartets.
Potassium ([Plate XIX], 2).
Potassium repeats the lithium spike; the central globe shows the "nitrogen balloon," which we already know, and which is surrounded on the proto level with six tetrahedra, which are set free on the meta and behave as in cobalt. Hence we have nothing new.
Rubidium ([Plate XIX], 3).
Again the lithium spike, modified slightly by the introduction of an ovoid, 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."
