NITROGEN (Plate XII, 1) does not assume the cubical form of its relatives, but is in shape like an egg.  Referring again to our 1895 investigations, I quote from them.  The balloon-shaped body (see 4 a) floats in the middle of the egg, containing six small spheres in two horizontal rows, and a long ovoid in the midst; this balloon-shaped body is positive, and is drawn down towards the negative body b (see 4 b) with its seven contained spheres, each of which has nine atoms within it—­three triads.  Four spheres are seen, in addition to the two larger bodies; two of these (see 4 d), each containing five smaller globes, are positive, and two (see 4 c) containing four smaller globes, are negative.

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.

III a.—­Aluminium, gallium and indium were examined from this group.  They
are triatomic, diamagnetic, and positive.  The corresponding group contains
phosphorus, arsenic and antimony:  bismuth also belongs to it, but was not
examined; they are triatomic, diamagnetic and negative.  They have no
central globes.
