the centre, and the globes circle round them. On the meta level all the
thirty bodies contained in the star separate from each other, and go on
their independent ways.

Selenium offers a beautiful example of the combination of simple elements
into a most exquisite whole.

TELLURIUM (Plate X, 3).

Tellurium very closely resembles cadmium, and they are, therefore placed on
the same diagram. The pillars are the same as in chlorine and its
congeners, with a duad added at the base. The ten-atomed ovoid is the same
as in cadmium and follows the same course in breaking up. It would be
interesting to know why this duad remains as a duad in selenium and breaks
up into a septad and triad in the other members of the group. It may be due
to the greater pressure to which it is subjected in selenium, or there may
be some other reason. The cross in tellurium is identical with that in
cadmium, except that the centre is seven-atomed instead of four-atomed.

III AND IIIa.--THE CUBE GROUPS.

We have here four groups to consider, all the members of which are triads,
and have six funnels, opening on the six faces of a cube.

III.--Boron, scandium and yttrium were examined; they are all triatomic,
paramagnetic, and positive. The corresponding group consists of nitrogen,
