VANADIUM (Plate XII, 2) closely follows scandium, having two types of
funnels. Funnel A only differs from that of scandium by having a globe (see
4 _d_) inserted in the ring of four ovoids; funnel B has a six-atomed,
instead of a five-atomed globe at the top, and slips a third globe
containing twenty atoms (see 4 _d_) between the two identical with those of
scandium (see 4 _c_). The central globe has seven atoms in its middle body
instead of four. In this way does vanadium succeed in overtopping scandium
by 126 atoms.

NIOBIUM (Plate XII, 3) is as closely related to yttrium as is vanadium to
scandium. The little globes that scamper round the "cigars" contain twelve
atoms instead of eight (see 4 _e_).

The rest of the funnel is the same. In the central globe both the
tetrahedra have "cigars," and a central nine-atomed globe spins round in
the centre (see 4 _f_), seventeen atoms being thus added.
