intended to be taken as a lesson to you personally.

There are sixteen chemical elements absolutely essential to healthy
human life, which are classified by physiological chemistry as the
elements of organic life. In the composition of vital tissues we
constantly find these basal elements: Carbon, oxygen, hydrogen,
nitrogen, sulphur, phosphorus, chlorine, potassium, sodium, magnesium,
calcium, iron, manganese, fluorine, silicon, and iodine. The function of
these elements will be discussed in a moment.

I would here lay stress upon the fact that the absence of the tiniest
ingredient necessary to the growth and functioning of an organ will,
according to the Law of the Minimum as laid down by Justus von Liebig,
result in disease, improper functioning and degeneration of that organ
or tissue.

Although the chemical salts constitute but a small part in the
composition of our bodies, and are a very small item in our daily diet,
their importance cannot be too strongly emphasized. They are the main
sources for the development of electro-magnetic energy in the blood and
nerves, and perform other services. I am of the opinion that "vitamines"
are neither more or less than these chemicals in proper proportion and
relation, but whether you agree or disagree with this conclusion, you
will instantly agree that the elements named above are indispensible to
perfect metabolism.

It goes without saying, of course, that no action in the world occurs of
itself, that is without impulse, hence the body must be given impulse to
growth. A series of chemical and physical facts indicate that phosphorus
plays this vital part. The property of phosphoric acid of uniting with
