It completely covers the surface of the earth and extends outward to a distance of more than fifty miles. As man was built to live on the outer crust of the earth surrounded by air the menorgs found certain elements of the air as well as the soil that became primarily useful and necessary to his existence. The most important element of the Air that man depends upon for the life and movement of his body is Oxygen. The chemists' formula for oxygen gas known as O 2 states that a molecule of oxygen gas consists of two atoms. They standardize the weight of one oxygen atom as 16 and the weight of a molecule of oxygen gas as 32 in comparing molecular weights of gaseous substances.
Man breathes the air.
If it were not for the external pressure of the air upon his body the internal pressure of the gases within would explode him. The temperature of the air keeps man from either freezing or roasting. The power to move the muscles of the body is caused by uniting oxygen gas from the air breathed with the digested fuel foods that cause oxidation. So the menorgs arranged a system of respiration to draw into the body of man the life giving elements from the air and throw out the death dealing gases of wastage. A passageway from the nostrils to the lungs was provided through which currents of air are drawn to the lungs and currents of waste gases are forced back into the air.
