achinery of the body in working order.

Electro-magnetic attraction and resistance are the agencies which
control metabolism and the action of the organs, so long as bodily
strength and healthy blood are maintained. All internal and external
stimuli are nothing more than electro-magnetic processes.

Even our bodily temperature, as we commonly think of it under such
conditions, resolves itself into electro-magnetic force or its product.

Electricity, magnetism, light, and heat differ only in respect to
vibration, and are in the final analysis one and the same.

But since our bodies are not cold like the earth or, like its electric
forces, vibrate slowly, but are warm and of quick vibration, we are
sufficiently assured that they contain, not only the cold
electro-magnetic forces, of slow vibration, but also those that are warm
and vibrate rapidly. And thus, when a correct relation exists between
positive and negative forces--that is to say, between the forces of
electricity and magnetism, then only have we normal temperature, _then
alone are we normally healthy_.

When we come to enquire into the sources from which the body obtains
these forces, there is little to be said. They are well known, can
easily be traced, but to the keenest mind of scholarly research their
source of origin is still an unturned page.

Of things in the human economy which count, however, first in importance
are food and breath; for in every atom of food we eat and every breath
of air we breathe there are electrons which enter the body, there to be
seized by the attraction of electro-magnetic action, stored away, and
applied in vital processes.

A source of vital energy, commonly known and little recognized, is the
free, pure air, or, ether charged with the electrons of space.

Out of space, positive and negative electrons constantly pass into the
human body, their effect we feel at once; when, for instance, in a cold
room, we commence to feel chilly, or on removal to a warm room, or into
the sunlight, a comfortable feeling of warmth pervades the body and
restores its normal temperature.

Weather and local conditions have no small influence upon our state of
health. In dry and elevated positions or in warm weather the condition
of the body is more positive; in damp, low-lying places and in raw
weather the electro-magnetic forces have a negative tendency. _This is
the explanation of those disturbances of health which occasionally arise
and
