We may assert, further, that the forces of the earth are electrical, whilst those of the sun are magnetic. In support of this assertion the proof may be advanced that a magnet can raise a heavier load after lying in the sunlight; for the close affinity, between magnetism and sunlight are, in this way incontestably demonstrated.
The interchange of these principles underlies all mundane activity and existence, and upon its cessation life would wholly disappear from the planet.
The various organs of the body, like everything else, fall under the immediate influence of this interchange of polar forces. The same electric or electro-magnetic opposition exists therein as are elsewhere apparent in nature and, for evidence of the same we have not far to seek.
The phenomena occurring in electrolysis—the science of chemical decomposition by galvanic action—are well known.
When a current of electricity passes through a fluid capable of decomposition the acids gather about the positive pole and the alkalies about the negative pole. We thus detect the exercise of separate activities on the part of the positive and negative electrical forces,—their polarization,—when we notice that alkalies and acids separate upon the application of electrical forces.
Similar conditions exist in our bodies.
They occur in the mucous and serous membranes; for the serous secretions react acid, the mucous ones, alkaline.
The contrast, in anatomical structure, between the mucous and the serous membranes is due to the fact that they line the various organs, respectively, within and without. It also indicates an opposition in their electro-magnetic forces.
These membranes cover, not only the large organs, but also the small ones, to the smallest muscular fibres.
In this way an electro-magnetic contrast exists in every part of the body, and it is this opposition Of forces which keeps the vital machinery of the body in working order.
