GERMANIUM (Plate XVI, 2) shows the eight funnels, containing each four
segments (XVI, 4), within which are three ovoids and a "cigar." In this
case the funnels radiate from a central globe, formed of two intersecting
tetrahedra, with "cigars" at each point enclosing a four-atomed globe.

TIN (Plate XVI, 3) repeats the funnel of germanium, and the central globe
we met with in titanium, of five intersecting tetrahedra, carrying twenty
"cigars"; the latter, however, omits the eight-atomed centre of the globe
that was found in titanium, and hence has one hundred and twenty atoms
therein instead of one hundred and twenty-eight. Tin, to make room for the
necessary increase of atoms, adopts the system of spikes, which we met with
in zinc (see Plate IX, 2); these spikes, like the funnels, radiate from the
central globe, but are only six in number. The twenty-one-atomed cone at
the head of the spike we have already seen in silver, and we shall again
find it in iridium and platinum; the pillars are new in detail though not
in principle, the contained globes yielding a series of a triplet, quintet,
sextet, septet, sextet, quintet, triplet.
