these same secretions build up and
maintain the body's resistance to dis
ease by cleansing the blood OF the
different poisons which 1t accumu-
lates in its current from time to time.
1t Is believed that the internal gland
secretions whet the appetite of the
white blood corpuscles, or leucocytes,
the body's germ destroyer. as a step
In this protective plan.
The biochemic salts involved in the
breaking down (katabolic) and the
building up (anabolic) processes OF
the body; the 16, and perhaps more.
mineral elments existing In organic
or living form in the universe and re-
quired to maintain the metabolism Of
all the cells of the human body, are
governed, regulated and controlled by
the ductless glands. This, Of couse,
is a reciprocal reaction, because
obviously there must be something to
govern If the glands are to function,
and 1t is equally obvious that the
glands cannot function in the absence
Of these elements or minerals. There
being no ducts leading into these
glands, 1t is very clear that nothing
can get either into or out Of them
except by means of the blood stream.
Hence, the profound physical and men

rangement in the natural or physiolog-
ical food supply.
The largest of the ductless glands is
the thyroid. situated In the fore part
Of the neck, midway between the
Adams apple" Thyroid cartilage)
and the top of the breastbone (stern-
um), point just behind where the
average man wears his collar button.
The gland comprises two sections. or
lobes, one lying on either side OF
the windpipe (larynx), connected by
a neck, OF isthmus, the whole forming
fat, oval body about three inches
long.
Because the general shape suggests
a long, oval, shield, the name thy
roid" was taken from the Greek Ian
guage-it means, literally, shieldlike.
The thyroid gland is reddish-brown
in color and has vascular structure

Der. may be found along the lower
windpipe (trachea) from the larynx
as far down as the heart These ac-
cessories possess the same vascular
structure and are supposed to have
a function similar to that Of the thy
roid body.
There are several highly significant
facts in connection with the general
structure and composition Of the thy
roid body that 1t Is advisable to keep
constantly in mind while considering
this subject Throughout the whole
range OF animal and vegetable life the
catalytic engines. or ferments, are
constantly busy. They are vitality
and fundamentally concerned with life
in all its phases, so much SO that phys
iology is rapidly resolving itself into
q branch Of catalysis.
No other gland, large or small. re-
ceives proportionally so great and d.
rect q supply of blood as the thyroid.
All these facts considered together
are sufficient to warrant US in accept
ing the thyroid as most important
organ and should also prepare US to
expect very grave physical results
from any disturbance Of It's functions.
Snugly tucked away behind the thy
roid, two Of them on either side of
the larynx and often actually imbed-
ded in the tissue OF that gland, are
four small bodies known as the par

from the kidney; "ad" meaning addi-

Suspended by short stalk from the
under surface OF the brain hangs an
other OF these pealike bodies, or baby
glands. The early students of physi-
ology believed this gland prepared
phlegm or mucus for the moistening
of the membrane Of the nose. and they
therefore called 1t the pituitary. /"
which means the phlegm former. The
