In Tables I and II, I have endeavored to present in concise and comprehensive form the primary and the secondary causes or manifestations of disease and the corresponding natural methods of treatment.

Violations of Nature's Laws in thinking, breathing, eating, drinking, dressing, working, resting and in moral, sexual and social conduct result in the following:
