but the bases are in contact and set at right angles to each other; the
second apex is not seen, as it is directly below the first. The pyramids
separate as meta-bodies, and the atoms assume the peculiar arrangement
indicated and then break up into four pairs and two units on the hyper
level.

SILVER (Plate VI, 4 and Ag below).

Silver presents us with only two new bodies, and even these are only new by
slight additions to old models. The triangular shaped body at the apex of
the funnel, containing 21 atoms, is intermediate between the similar bodies
in copper and iron. As a proto-element it becomes three triangles, joined
at their apices, in fact a tetrahedron in which no atoms are distributed on
the fourth face. The faces separate on the meta level and give three
seven-atomed figures, and each of these breaks up into two triplets and a
unit. The central globe only differs from that of bromine by the addition
of one atom, which gives the familiar four-sided pyramid with a square base
as in chlorine (see p. 46).

GOLD (Plate VII and Au below).

[Illustration]

The disintegration of gold first yields forty-seven bodies on the
proto-level; the twenty-four funnels separate, and the central globes which
hold each twelve together set free their six contained globes (_c_, _d_),
