on the chemical conditions of the infusion at the time the microscopic
examination is made. Change the conditions, or defer the examination until
the conditions themselves are changed, and other and different forms of
life will make their appearance, in harmony with the physiological law we
have named.

This wonderful play of the vital forces of nature is no less dependant on
"conditions"--on the necessary pre-existing plasma, chemically balanced
soils, organic solutions, etc.--than the alleged "dynamical aggregates,"
"_molecules organiques_," "plastide particles," or "highly differentiated
life-stuff," insisted upon by the physicists, in their materialistic
theories of life. These physicists make even the slightest change in
developmental phases--whether statical, as in the case of crystals, or
dynamical, as in the case of living organisms--to depend on physical
conditions,--those aiding and abetting what they call the "molecular play
of physical forces." But with their theory that matter and motion are the
only self-subsistent, indestructible elements in the universe, what
"molecular play" can be attributed to matter but that which is derived
from motion, or some one of its alleged correlates? We can only imagine
two sorts of motion as possible metaphysical conceptions in connection
with matter--_molar_ motion, or that relating to matter moving in mass,
and _molecular_ motion, or that relating to the movements of matter in its
unaggregated form, or as confined to molecules.

But motion itself is not an absolute entity. It is not so much even as a
collocating or placing force of matter itself. It is, at best, only a
mechanical impulse imparted by one moving body to another; or, more
accurately speaking, a continuous change of place in a moving body. In
other words, it is simply a _process_ or _mode_ of action, and stands in
about the same relation to matter as _growth_ does to a living plant or
