Two of these spheres
are identical in their contents--two quintets (7 _f_), a quintet (7 _j_),
and two quintets (7 _e_), _e_ and _f_ being to each other as object and
image. The remaining sphere (7 _b_) is identical with the highest in the
calcium funnel. The remaining two spheres, one below the other, are
identical with the corresponding two spheres in calcium. The central globe,
as regards its external segments, is again identical with that of calcium,
but in the internal segments a six-atomed triangle (7 _k_) is substituted
for the calcium four-atomed one (7 _e_).

MOLYBDENUM (Plate VIII, 6) very closely resembles strontium, differing from
it only in the composition of the highest pair of spheres in the funnels
and in the presence of a little sphere, containing two atoms only, in the
middle of the central globe. The topmost spheres contain no less than eight
subsidiary spheres within each; the highest of these (7 _e_) has four atoms
in it; the next three have four, seven and four (7 _e_ _g_ _e_),
respectively; the next three are all septets (7 _g_), and the last has
four--making in all for these two spheres 88 atoms, as against the 48 in
corresponding spheres of strontium, making a difference of 160 in the four
funnels.
