adaptation of certain portions of the immense accumulation of cells to
diverse functions, which has necessitated the variable conformity of the
supporting elements. But all of these elements are in the blood, which
carries them in the necessary quantities to the different organs to
which they belong and where they are utilized to replace used-up matter.

I do not overlook the difficulty of grasping this idea of unity.

The fact, that it is so difficult to realize, has led to the greatest
errors in present day medical science.

It seemed at first sight, so obviously necessary to study the different
organs as entirely different groups, to work out a careful system of
bones, of intestinal organs, of blood-vessels, of nerves, and so on; all
of which is of course very valuable, in its place, but only from a
descriptive standpoint.

Anatomy shows us what life has produced in the construction of a human
form, but it does not indicate the source of life, nor, consequently,
the source of health.

It is well to know the different forms of cell accumulations, which are
called organs, but if we desire to keep them in good order, we must
watch closely what is common to them all; for it is only from this point
of view, that we are able to determine the necessary, and possibly, the
lacking elements for purposes of healing.

Thus, as one of the greatest achievements of modern science, we come to
the one most vital thing, so sorely needed and yet so badly neglected
throughout the centuries: _The chemical analysis of the human body and
