ork 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
