We look at it in perfect health which means perfection and harmony not in part, but of the whole body. So far we are only filled with love, wonder and admiration. Another period of observation appears to the philosopher. We find partial or universal discord from the lowest observable to the highest in action and death. Then the book of whys is opened and displays its leaves which calls out mental labor even to the degree of agony, to know the cause or causes that produce a failure of a limb in sensation, motion, nutrition, voluntary and involuntary functional exhibits. His mind will explore the bone, the ligament, the muscle, the fascia, the channels through which the blood travels from heart to local destiny, with lymphatics and their contents,—the nerves, the blood vessels and every channel through or over which all substances are transmitted all over the body, particularly the disabled limb in question. It proceeds too and does obtain blood abundantly to and from the heart, but the results obtained are not satisfactory, and another leaf is opened of why no good results are obtained and where is the mystery, what quality and element of force and vitality has been withheld? A thought strikes him that the cerebro spinal fluid is the highest known element that is contained in the human body, and unless the brain furnishes this fluid in abundance a disabled condition of the body will remain. He who is able to reason will see that this great river of life must be tapped and the withering field irrigated at once, or the harvest of health be forever lost.
CHEMISTRY.
As chemical compounds are not known to Osteopathy to be used as remedies, then its use as a study for the student is only to teach that elements in nature do combine and form other substances, and without changes and unions, no teeth, bone, hair, or muscle could appear in the body from the food eaten. Then chemistry is of great use as a part of a thorough Osteopathic education. It gives us the reasons why food is found in the body as bone, muscle and so on, to all kinds of flesh, teeth and bones found in animal forms. Unless we know chemistry reasonably well, we can not do away with much mental worry of what becomes of food after eating. By chemistry the truths of physiology are firmly established in the mind of the student of nature, that in man a chemistry of wonderful powers does all the work of animal forms, and that in the laboratory of nature's chemistry is the ruling power. By elementary chemistry we are led to see the beauties of physiology only. Thus chemistry of the elementary is one, and physiology is the witness that it is law in man as in all nature. Thus in chemistry we comprehend some of the laws of union in nature which we can use mentally with knowing confidence. In chemistry we become acquainted with the law of cause and change in union, which is a standard law sought by the student of Osteopathy.
NATURE'S CHEMISTRY.
Osteopathy believes that all parts of the human body do work on chemical compounds, and from the general supply manufacture for local wants; thus the liver builds for itself of the material that is prepared in its own division laboratory. The same of heart and brain. No disturbing or hindering causes will be tolerated to stay if an Osteopath can find and remove it. We must reason that to withhold the supply from a limb, to wither away would be natural. We suffer from two causes. First, want of supply (hunger), and the burdens of dead deposits along nerve centers, which five nerves by chemical changes while in fermentation should regulate local or general divisions.
CORRECT METHOD OF REASONING.
In concluding this chapter we will confine our labor to an effort to direct the beginner to a correct method of reasoning. When he is brought face to face with the stern realities of the "sick room," the Osteopath begins his inquiries and follows with his questions just far enough to know what division of the body is in trouble. If he finds an arm has lost motion, he goes to arm to explore for cause. He can begin his hunt for cause at hand, explore it carefully for wounds, strains or any lesion that could injure nerves of the arm. If he finds no probable cause there, he should explore bones for dislocations or strains of ligaments at elbow; if he finds no defect there sufficient to locate cause in lower arm or hand; he has only two more places left to inspect, the shoulder and neck with their articulations of bone and muscles. If found normal at shoulder, then go to neck, out of which go all or most of the nerves of the arm; if he finds no lesion or cause equal to the trouble so far, then he has been careless in his search and should go over and over from marrow to periostium of all bones of the neck and head, because there are only five divisions in which a lesion can exist. Carefully look, think, feel and know that the head of the humerus is true in the glenoid cavity, clavicle true at both ends of its articulation, with sternum and acromion processes. See that the biceps are in their grooves, and ribs on spine are true at manubrium and spine, and that neck is true on first dorsal. True in all joints of the neck, as the nerves of the arm come from the neck, there must be no variation from normal, or trouble will appear from that cause. As the neck has much to do with the arm, we should keep a living picture of the forms of each bone, how and where it articulates with others, how it is joined by ligaments, what blood vessels, nerves and muscles cross or range with it lengthwise, because to overlook a small nerve and blood vessel you may fail to remove a goitre, and all diseases of the head, face and neck.
