Without this knowledge on the part of the reader, the words of this philosophy will fall as blanks before reaching his magazine of reason. Thus this is addressed to the independent man or woman that can, will and does reason. THE DIAPHRAGM INTRODUCED. At this point we will introduce the diaphragm, which separates the heart, lungs and brain from the organs of life that are limited to the abdomen and pelvis. A question arises at this point; what has the diaphragm to do with good or bad health? At this time we will analyze the diaphragm; we will examine its construction, and its uses; we will examine its openings through which blood passes both above and below. We will examine the opening through which food passes to stomach. We will carefully examine the passage or opening for nerve supply to the abdomen below, to run this great system of chemistry, which is producing the various kinds of substances necessary to the hard and soft parts of the body. We must know the nerve supply of the lymphatics, womb, liver, kidneys, pancreas, the generative organs, what they are, what they do, and what are demanded of them, before we are able to feed our own minds from the cup that contains the essence of reason as expressed from the tree of life. A USEFUL STUDY. The diaphragm surely gives much food to the one who would search for the great whys of disease as reported causes seem to be far back in the fogs of mystery. It may help us to arrive at some facts if we take each organ and division and make a full acquaintance of all its parts and uses before we combine it with others. COMBATTING EFFECTS.
