two atoms form a duad; _i_, which repeats _f_, makes a ring with the fifth
in the centre, as in the five-atomed _b_ of calcium, as shown above. There
is, thus, nothing new in strontium, but only repetitions of forms already
studied.

OXYGEN (PLATE VIII, 4).

[Illustration]

The disintegration of oxygen as given in 1895 may be repeated here, and the
better presentation given on p. 54 renders it easier to follow the process.
On the proto level the two "snakes" divide; the brilliant disks are
seven-atomed, but are differently arranged, the positive snake having the
atoms arranged as in the iodine ovoids, whereas the negative snake has them
arranged as in a capital H. The snakes show the same extraordinary activity
on the proto level as on the gaseous, twisting and writhing, darting and
coiling. The body of the snake is of two-atomed beads, positive and
negative. On the meta level the snakes break into ten fragments, each
consisting of a disk, with six beads on one side and five on the other,
remaining as lively as the original snake. They shiver into their
constituent disks, and beads on the hyper level, there yielding the ten
disks, five positive and five negative, and the 110 beads, fifty-five
positive and fifty-five negative.

CHROMIUM (PLATE VIII, 5).

When we go on to chromium and molybdenum, we return to our familiar funnels
and central globes, and the secondary spheres within the funnels--quickly
set free, as before, on the proto level--give us no new combinations in
their contained spheres and ovoids. The _a_ of beryllium, the _b_ of
