The reader may well wonder what all these metals have to do in the

economy of the human body.  The answer is that their action is mainly

catalytic, a catalyst being a substance in the presence of which a chemical

action proceeds which would otherwise go very slowly or cease altogether.

For example, without the presence of copper in the lungs, the interaction

between iron and oxygen falls below the rate that is essential to life,

whereas if the lungs have their proper supply of copper, the rate of reaction

is kept up to a healthy standard.  The intelligence of man has made use of

this valuable property of catalytic action for a variety of industrial

processes, and yet there are many who would deny any evidence of Divine

intelligence in creation.

Not only is the human body composed of these wonderful elements and

salts, but the food provided for man (as indicated in Gen. 1:29) is rich in

these elements and salts in their most assimilable form.

'And God said, Behold, I have given you every herb bearing seed, which

is upon the face of all the earth, and every tree, in the which is the

fruit of a tree yielding seed; to you it shall be for meat' (Gen.

How much did Moses know of vitamins and inorganic salts?  And yet

subsequent investigation has revealed that the food indicated in Genesis 1:29

is scientifically perfect.

The following table gives some of the elements present in seeds, roots,

and fruits:

Stems, Leaves and Fruits.--

Potassium, sodium, iron, sulphur.

Seeds and Roots.--

Potassium, phosphorus, magnesium.

Seeds Themselves.--

The outer part.-- Calcium, sodium, magnesium,

sulphur,  fluorine,  and  silicon.

The inner part.-- Potassium and phosphorus.

It is interesting to note that there is a similarity between the

constitution of the human body and that of seeds.  The muscular tissues, like

the inner part of the seed, employ potassium and phosphorus, while the blood

and skin correspond in composition with the outer part of the seed.

Perhaps the reader would appreciate a few further words on the

essential work that some of these elements perform.

Potassium, which figures so largely in the composition of seeds, is the

mineral basis of all muscular tissues, and is essential in the

formation of proteins.  It can be truthfully said: 'No life without
