There must be a sufficient amount of proper food to repair the inevitable waste in the nervous tissue arising from the production of organic and intellectual activity. The mind cannot be in harmony with itself and its surroundings when the body is enfeebled or irritated from an impoverished or plethoric condition of the blood, resulting from a violation of some of the basic or fundamental laws of human existence. That the human body is a system of machines, each requiring to be fed in a given time with a given amount of food material of a peculiar character, is an important consideration that physiologists have overlooked. To supply each tissue with food adapted to meet the waste resulting from its function and at the same time to avoid an excess that can only burden the digestive organs, is the basic principle of dietetic science. In the present dietetic system, fat-forming and muscle-forming food is the rule, and nerve and brainbuilding material is the exception. Non-azotized food is insufficient for a brain stimulant.

Brain stimulants being so universally used, indicates some want or necessity that their use supplies; it is found that they temporarily supply the place of brain or nerve food. A brain stimulant, by increasing the force and rapidity of the circulation of the blood in the nervous tissue, heightens and intensifies its intellectual and organic function through a proportionally increased function of nutrition.

Thousands who possess the most efficient brain power use alcoholic stimulants to relieve mental depression, often resulting from an unfortunate combination of confluent circumstances, or more frequently by an obstructed circulation and exhausted nervous force; and not until they are stricken down by it with diabetes or epilepsy or paralysis are they conscious of their inconsiderate and deplorable

habits.

One of the remedies for intemperance is nerve-food building material, to supply the waste of the nervous tissue. There should be a reform in the present dietetic system, in reducing the proportion of fat and muscle forming elements and increasing the nerve and brain-building material in a proper ratio. Stimulating poisons will be supplanted by food beverages that will so invigorate and energize, without stimulating, that there will be no sense of mental and physical craving which is to-day temporarily appeased by the use of noxious beverages.

There are three kinds of food or nutrition which possess different and specific quantities of positive and negative vitality. There are negative, passive and positive, combinations of matter which man selects and appropriates to the want and perpetuation of his constitution. And it is necessary to health and happiness that he ascertain why and where these combinations exist, and how and when to adapt them to his system. He must learn what to eat when diseased, and when he is healthy, how to confirm and preserve harmony throughout his being.

AIR IS ONE OF NATURE'S INSTRUMENTALITIES.

Air is a powerful agent in the production of harmony or discord, or in the chemical generation of health or disease. We may as safely eat poisoned food as breathe poisoned air. As corrupt solid food poisons the system through the blood, so does bad air in like manner poison and produce those affections of the entire system characterized as general diseases.

Providence is not responsible for what ignorance and neglect attribute to its divine dispensation. Death lurks in many things and in many places; bad judgment, bad air, in dark and damp places. Organic poisons, analogous to the poisons

which propagate epidemic and contagious diseases, are rendered innocuous by free exposure to light and sunshine.

Light aids in the development of the different parts of the body. Pure air is absolutely essential to health and physical beauty. And nothing is so excellent for soul and body as a good, solid bar of sleep, between day and day, provided it be taken in a room thoroughly ventilated.

Breathe pure air; live with open windows, and the windows of heaven will be more likely to open to you. Form the right habit of hygienic living and learn how to take proper care of your bodies. Without exercise and fresh air, there can be no healthy and beautiful growth.

The lungs are made and adapted to the atmosphere, with a capacity for inhaling a certain amount of atmospheric air; the blood and other parts of the physical system require a given amount of electricity to develop and make them healthy; consequently, air must be kept in active circulation, the extent according to the weather.

We breathe, on an average, twelve hundred times per hour, inhale six hundred gallons of air, or twenty-four thousand gallons per day. The electricity is contained in the oxygen of the air, and has no means of communication with the interior of man but by the lungs; hence, if by any means they are rendered incapable of receiving it, the consequence is they cannot transmit it to the system; therefore, the system must be without it, and hence, electricity being the grand vitalizing element, the system must sink in the same proportion that this is withheld; and, sooner or later, death from exhaustion must ensue. In the act of inspiration, the oxygen is retained or separated by the lungs from the nitrogen and transmitted to the venous or negative blood, while the nitrogen is expelled from the lungs in the condition of carbonic acid gas. In obedience to the law that like polarities.

repel, the blood is driven from the lungs, the great magnate, to the heart, and thence throughout the body; and after losing its positive electricity, while on its journey through the arterial system, it is then received into the capillary vessels, and from thence to the veins, and finally back to the right portion of the heart and lungs. The heart is the regulating organ, on the principle that unlikes attract.

An adult will exhale six gallons of carbonic acid per hour. The lungs, in twenty-four hours, discharge fifteen ounces of volatile matter, while the skin discharges, in the same time, thirty ounces.

Suppression of the action of the skin becomes speedily fatal by the accumulation of carbonic acid and other poisonous materials. The skin is closely akin to the lungs. It also breathes in its way-imbibing oxygen and throwing off carbonic acid. And with its miles of living tubes, and millions of minute pores, through which are hourly sifted noxious substances, it cannot be neglected with impunity. It is computed that we cast off, through the skin, greater quantities of matter than through the kidneys and bowels. These matters are rank poisons, and largely float in the surrounding atmosphere.

When the atmosphere is loaded with moisture, and when with moisture there is cold, or when with moisture there is great heat, the body cannot throw off its secretions from the skin and lungs so freely as when the atmosphere is crisp and dry. When the air is heavy and close, the body is unable to throw off freely its secretions, and, with the change that takes place in the activity of its animal chemistry, it becomes for a time oppressed, and the mind weary and woebegone.

Too much cold shrinks the skin, and too much heat dries" it up, the bodily heat is lowered, the extremities chilled as

the blood presses unduly on the brain. Wisdom will seek the golden mean.

THERE IS A MORALITY IN PURE BLOOD.

Inflammatory matter circulating in the body causes abnormal brain action. The blood is a fluid of amazing complexity, holding in exquisite balance the constituents from which the whole being is elaborated. All delicacies of feeling and niceties of thought depend upon its purity. If the stomach, liver and heart are diseased, so are the morals; a week's neglect or wrong living may drive a person to vice and immorality. The physical is the substratum of the spiritual, and this fact ought to give to the food we eat, and the air we breathe, a transcendental significance.

Man is a compound of all nature, and all things are adapted to his nature and wants. Chemistry tells us that the blood is composed of eighteen different elements, and also that the atoms resemble a spangle in shape, being thin and circular, with a dot of iron in the middle; so the wheels of life may be said to run on iron axles. Oxygen generates an acidity in the blood, in some degree answering to the solution of the sulphate of copper in the galvanic battery. The electro-nervous fluid is transmitted to all portions of the physical system for the express purpose of enabling them to perform their legitimate functions.

The nervo-vital fluid secreted by the brain is of a galvanic nature, and is manufactured from electricity which we breathe into the lungs at every inspiration we take. Electricity is the only matter that can come in contact with mind, and is the only agent by which the will contracts the muscles. The will vibrates the nervous fluid, which then contracts the muscles. Electricity is the only correspondent or mediator between mind and matter, and brings them into communication.
