only differs in having the central atom, and breaks up similarly, setting
the central atom free. The ovoid _c_ sets free its four contained globes,
and the ovoid _d_ sets free the three within it. Thus sixty-one proto
elements are yielded by titanium. On the meta level, _c_ (titanium 3)
breaks up into star-like and cruciform bodies; the component parts of these
are easily followed; on the hyper level, of the four forms of triplets one
behaves as in carbon, and the others are shown, _a_, _b_ and _f_; the
cruciform quintet yields a triplet and a duad, _c_ and _d_; the tetrahedra
yield two triplets _g_ and _h_, and two units; the septet, a triplet _k_
and a quartet _j_. On the meta level, the bodies from _d_ behave like their
equivalents in sodium, each _d_ shows two quartets and a sextet, breaking
up, on the hyper level, into four duads and two triads.

ZIRCONIUM (Plate XV, 2, 5).

Zirconium reproduces in its _c_ the four forms that we have already
followed in the corresponding _c_ of titanium, and as these are set free on
the proto level, and follow the same course on the meta and hyper levels,
we need not repeat them. The central globe of zirconium _c_ sets free its
nine contained bodies; eight of these are similar and are figured in the
diagram; it will be observed that the central body is the truncated "cigar"
of carbon; their behaviour on the meta and hyper levels is easily followed
there. The central sphere is also figured; the cigar follows its usual
course, and its companions unite into a sextet and an octet. The _d_ ovoid
liberates five bodies, four of which we have already seen in titanium, as
the crosses and sextet of sodium, and which are figured under titanium; the
four quartets within the larger globe also follow a sodium model, and are
given again.
