The contained bodies in the pillars run three, four, five, four, three,
two, instead of starting with two; and a quartet replaces a duad in the
globes above. The central cross only differs from that of cadmium in having
a seven-atomed instead of a four-atomed centre. So close a similarity is
striking.

We must now consider the ways in which the members of the tetrahedral
groups break up, and as we proceed with this study we shall find how
continual are the repetitions, and how Nature, with a limited number of
fundamental methods, creates by varied combinations her infinite variety of
forms.
BERYLLIUM (Plate III, 2, and VIII, 1).

Beryllium offers us four similar funnels and a central globe, and the
proto-elements consist of these five bodies, set free.
