In animals and vegetation the temperature is increased by a greater atomic action, while in inanimate substances the heat is increased by a greater molecular vibration. Heat production in the animal economy is created by the vibration of molecules of which nerves are composed. It is a biological fact that nerves vibrate in proportion to the amount of tension. There is no special center for heat production, regulation and dissipation. Heat is a function of the whole nervous system, a discovery made by D. D. Palmer on July 1, 1903.
Fever is a symptom, it is associated with pathological conditions.
The quantity of heat is regulated by the amount of nerve-vibration. The orderly manner is determined by nerve tension. The tissue of the nerve itself does not furnish the energy or the force. Intelligence produces the actions which constitute life by animating the material body. The usefulness of fever is made manifest by M. D. s while sitting at the bedside of the patient, waiting and watching for the crisis of fever.
