But each funnel now has three segments
instead of two; three funnels out of the six contain two segments of type A
and one of type B; the remaining three contain two of type B, and one of
type A.

The corresponding negative group, phosphorus, arsenic, and antimony, run on
very similar lines to those we have just examined.
[Illustration: PLATE XIV.]
PHOSPHORUS (Plate XIV, 1) offers us a very curious arrangement of atoms,
which will give some new forms in breaking up. Two segments are in each
funnel, in fact the only two of group III _a_ which do not show this
arrangement, or a modification thereof, are aluminium and arsenic.
PHOSPHORUS: Left segment 50 atoms
Right segment 43 "
