funnel is our introduction to the body marked _a_ 110. This body was
observed by us first in nitrogen, in 1895, and we gave it the name of the
"nitrogen balloon," for in nitrogen it takes the balloon form, which it
also often assumes in other gaseous elements. Here it appears as a
sphere--the form always assumed on the proto level--and it will be seen, on
reference to the detailed diagram 4 _a_, to be a complicated body,
consisting of six fourteen-atomed globes arranged round a long ovoid
containing spheres with three, four, six, six, four, three, atoms
respectively. It will be observed that this balloon appears in every member
of these two groups, except boron.

The B funnel runs largely to triads, _c_ and _b_, _b_ (see 4 _b_) having
not only a triadic arrangement of spheres within its contained globes, but
each sphere has also a triplet of atoms. In _c_ (see 4 _c_) there is a
triadic arrangement of spheres, but each contains duads. B is completed by
a five-atomed sphere at the top of the funnel. It should be noted that _a_,
_b_ and _c_ all are constituents of nitrogen.

The central globe repeats that of boron, with an additional four-atomed
sphere in the middle.
