All these laws must be fulfilled to the letter, otherwise a failure is absolute. As the great laboratory of nature is always at work in the human body, the chilling winds and poisonous breaths, with extremes of heat and cold at different seasons of the year by day and night, and the lungs and skin are continually secreting and excreting every minute, hour and day of our lives, is it not reasonable to suppose that we inhale many elements that are floating in the common winds that contain the seeds of some destructive element, to the harmony of fluids that are necessary to sustain the healthy animal forms. GENERATING FEVER. Suppose it should start the yeast, or kind of substance that lives greatly upon lime. If this yeast in its action and thirst for food to suit its life and appetite should call in from the earth, water and atmosphere for its daily food lime substances only, and by its power destroy all other principles taken as nourishment, is it not reasonable to suppose it would deposit such elements in over powering quantities in the fascia of the mucous membrane of the lungs in such quantities, as to overcome the renovating powers of the lungs and excretory system, by its paralyzing quantities of diseased fluids, all through the universal fascia of animal life. This deposit acts as an irritant to the sensory nerves to such an extent that the electricity of the motor nerves is forced to take charge of, and run the machinery of the human body, with such velocity as to raise the temperature of the body, by putting the electricity above the normal action of animal life, and thereby generate that temperature known as fever? The two extremes, heat and cold, may be the causes of retention and detention. One is detained by the contraction of cold until the blood and other fluids die by asphyxia. The warm temperature produces relaxation of the nerves, blood, and all other vessels of the fascia, during which time the arteries are injecting too great quantities of fluids to be renovated by the excretory systems. Thus you have a cause for decomposition of the blood and other substances, to be conveyed to the lungs for purification and renewal. You have a logical foundation and a cause for all diseases, catarrhal, climatic, contagions, infections, and epidemics. The fascia proves itself to be the probable matrix of life and death. Beginning with the mucous membrane penetrating all parts to supply and renovate the fluids of life, and nourishing all the nerves of nutrition and assimilation. When harmonious in normal action, health is good; when perverted, disease is destructive unto death. WHOOPING COUGH.
