as an
oblate spheroid, with the contained spiral much compressed and widened in
the centre; the spiral consists of three snakes, one positive and two
negative, formed in a single revolving body. On raising the chemical atom
to the next plane, the snake divides into three, each being enclosed in its
own egg.

The chemical atom of nitrogen was the third selected by the students for
examination, as it seemed comparatively quiet in contrast with the
ever-excited oxygen. It proved, however, to be the most complicated of all
in its internal arrangements, and its quiet was therefore a little
deceptive. Most prominent was the balloon-shaped body in the middle, with
six smaller bodies in two horizontal rows and one large egg-shaped one in
the midst, contained in it. Some chemical atoms were seen in which the
internal arrangement of these contained bodies was changed and the two
horizontal rows became vertical; this change seemed to be connected with a
greater activity of the whole body, but the observations on this head are
too incomplete to be reliable. The balloon-shaped body is positive, and is
apparently drawn downwards towards the negative egg-shaped body below it,
containing seven smaller particles. In addition to these large bodies, four
small ones are seen, two positive and two negative, the positive containing
five and the negative four minuter spots. On raising the gaseous atom to
E 4, the falling away of the wall sets free the six contained bodies, and
both the balloon and the egg round themselves, apparently with the removal
of their propinquity, as though they had exercised over each other some
attractive influence. The smaller bodies within the egg--marked _q_ on
E 4--are not on one plane, and those within _n_ and _o_ form respectively
square-based and triangular-based pyramids. On raising all these bodies to
E 3 we find the walls fall away as usual, and the contents of each "cell"
are set free: _p_ of E 4 contains six small bodies marked _k_, and these
are shown in _k_ of E 3, as containing each seven little bodies--marked
_e_--each of which has within it two ultimate atoms; the long form of _p_
E 4--marked _l_--appears as the long form _l_ on E 3, and this has three
pairs of smaller bodies within it, _f'_, _g_ and _h_, containing
respectively three, four and six ultimate atoms; _q_ of E 4, with its seven
contained particles, _m_, has three particles _m_ on E 3, each showing
three ultimate atoms within them; _e_ f
