he same functions as the
one that was thrown off by the tree last autumn.

The skin renews itself through the casting off of used cells (those that
have already performed their functions) most rapidly, taking but a few
weeks. The muscles, the vital organs, the entire arterial system, the
brain and the nervous system all take longer, but all are practically
renewed within a year, some in much less time. Then comes the bony
structure, taking the longest, varying, we are told, from seven and
eight months to a year, in unusual cases fourteen months and longer.

It is, then, through this process of cell formation that the physical
body has been built up, and through the same process that it is
continually renewing itself. It is not therefore at any time or at any
age a solid fixed mass or material, but a structure in a continually
changing fluid form. It is therefore easy to see how we have it in our
power, when we are once awake to the relations between the conscious
mind and the subconscious--and it in turn in its relations to the
various involuntary and vital functions of the body--to determine to a
great extent how the body shall be built or how it shall be rebuilt.

Mentally to live in any state or attitude of mind is to take that state
or condition into the subconscious. _The subconscious mind does and
always will produce in the body after its own kind._ It is through this
law that we externalise and become in body what we live in our minds. If
we have predominating visions of and harbour thoughts of old age and
weakness, this state, with all its attendant circumstances, will become
externalised in our bodies far more quickly than if we entertain
thoughts and visions of a different type. Said Archdeacon Wilberforce in
a notable address in Westminster Abbey some time ago: "The recent
researches of scientific men, endorsed by experiments in the Salpetriere
in Paris, have drawn attention to the intensely creative power of
suggestions made by the conscious mind to the subconscious mind."

THE POWERFUL AID OF THE MIND IN REBUILDING BODY--HOW BODY HELPS MIND

"The body looks," some one has said, "as old as the mind feels." By
virtue of a great mental law and at the same time chemical law we are
well within the realm of truth when we say: The body ordinarily is as
old as the mind feels.

Every living organism is continually going through two processes: it is
continually dying, and continually being renewed
