or sometimes on one and sometimes on the other? In soft iron, for instance,
are the internal arrangements of the chemical atom forcibly distorted, and
do they elastically return to their original relations when released? and
in steel is the distortion permanent? In all the diagrams the heart-shaped
body, exaggerated to show the depression caused by the inflow and the point
caused by the outflow, is a single atom.

[14] These sub-planes are familiar to the Theosophist as gaseous, etheric,
super-etheric, sub-atomic, atomic; or as Gas, Ether 4, Ether 3, Ether 2,
Ether 1.

[15] It must be remembered that the diagrams represent three-dimensional
objects, and the atoms are not all on a plane, necessarily.

[16] That is, the surrounding magnetic fields strike on each other.

[17] The fifth member of this group was not sought for.

[18] This, with references which appear later (pp. 32, 33, 50, etc.),
relates to articles which appeared in the _Theosophist_, 1908.

[19] Since writing the above I have noticed, in the _London, Edinburgh and
Dublin Philosophical Magazine and Journal of Science_, conducted by Dr.
John Joly and Mr. William Francis, in an article entitled "Evolution and
Devolution of the Elements," the statement that it is probable that in "the
nebulous state of matter there are four substances, the first two being
unknown upon earth, the third being hydrogen and the fourth ... helium. It
also seems probable that ... hydrogen, the two unknown elements, and helium
are the four original elements from which all the other elements form. To
distinguish them from the others we will term them protons." This is
