the two _c_ set free thirteen each; the four _d_ finally liberate two
each: 302 proto elements in all.

The funnel is almost that of iodine, re-arranged. Four of the first ring in
the iodine funnel are replaced by the triangular body, which becomes a
four-sided pyramid with an occupied base. The second ring of three ovoids
in iodine becomes four in gold, but the internal arrangement of each ovoid
is the same. The next two spheres in the iodine funnel coalesce into one
sphere, with similar contents, in the gold funnel. The fifth in iodine is
slightly rearranged to form the fourth in descent in gold, and the
remaining two are the same. _B_ has been broken up under occultum (p. 628)
and can be followed there. The sixteen rings set free from the four _a_,
after gyrating round the central body, now become a sphere, break up, as in
occultum (see p. 44) into a meta seven-atomed ring and an eight-atomed
double cross, and so on to the hyper level. The sphere with its two
contained bodies breaks up into eight triangles on the meta level, and each
of these, on the hyper, into a duad and a unit. The twelve septets of _c_
assume the form of prisms as in iodine (see p. 48) and pursue the same
course, while its central body, a four-sided pyramid with its six
attendants, divides on the meta level into six duads, revolving round a
ring with a central atom as in chlorine (p. 47), the duads going off
independently on the hyper-level and the ring breaking up as in chlorine.
The "cigar" tetrahedron of _d_ follows its course as in occultum, and the
other sets free two quartets and two triplets on the meta level, yielding
six duads and two units as hyper compounds. It will be seen that, complex
as gold is, it is composed of constituents already familiar, and has iodine
and occultum as its nearest allies.

II AND IIa.--THE TETRAHEDRAL GROUPS.

II.--This group consists of beryllium (glucinum), calcium, strontium and
barium, all diatomic, paramagnetic and positive. The corresponding group
consists of oxygen, chromium, molybdenum, wolfram (tungsten) and uranium,
with a blank disk between wolfram and uranium: these are diatomic,
paramagnetic, and negative. We have not examined barium, wolfram, or
uranium.

funnels are found, the mouth of each funnel opening on one of its faces.
The funnels radiate from a central globe, and each funnel contains fo
