Yttrium
(
, 3). Here we have a quite new arrangement of bodies within the funnel—the funnel being of one type only. Two "cigars" whirl on their own axes in the centre near the top, while four eight-atomed globes (see 4
e
) chase each other in a circle round them, spinning madly on their own axes—this axial spinning seems constant in all contained bodies—all the time. Lower down in the funnel, a similar arrangement is seen, with a globe (see 4
d
)—a nitrogen element—replacing the "cigars," and six-atomed ovoids replacing the globes.
The "nitrogen balloon" occupies the third place in the funnel, now showing its usual shape in combination, while the b globe (see 4 b) of scandium takes on a lengthened form below it.
The central globe presents us with two tetrahedra, recalling one of the combinations in gold (see [Plate VII] d), and differing from that only by the substitution of two quartets for the two triplets in gold.
