beings are not, zz their last phases, designed; as those produced 
by nervous diseases. 
The transition between the organic and the inorganic energies 
may be possibly found in the electric group. Its influence on life, 
its production of contractions in protoplasm, and its resemblance 
to nerve force, are well known. It also compels chemical unions 
otherwise impracticable, thus resembling the energy of the pro- 
toplasm of plants, whose energy in actively resisting the disinte- 
grating inorganic forces of nature is so well known. Perhaps this 
type of force is an early-born of the primitive energy, one which 
has not descended so far in the scale, as the chemism which 
holds so large a part of nature in the embrace of death. 
Vibration is inseparable from our ideas of motion or energy, 
not excluding conscious energy. There are reasons for supposing 
that in the latter type of activity the vibrations are the most rapid 
of all those characteristic of the forces. A center of such vibra: 
tions in generalized matter would radiate them in all directions 
With radiant divergence the wave lengths would become longes, 
and their rate of movement slower. In the differing rates of vibra- 
tions we may trace not only the different forms of energy, but 
diverse results in material aggregations. Such may have been 
the origin of the specialization of energy and of matter which 
we behold in nature. ap 
Such thoughts arise unbidden as a remote but still a legitimate 
induction, from a study of the wonderful phenomenon of am 
motion; a phenomenon everywhere present, yet one which re 
treats, as we pursue it, into the dimness of the origin of things 
And when we follow it to its fountain head, we seem tO have 
_ reached the origin of all energy, and it turns upon US, the king 
and master of the worlds.
