THE HUMAN MACHINE
MANS BODY AND ITS WONDERS OF
MECHANICAL DEVICES.

human body made that scientists are
beginning 20 realize that many OF the
inventions OF the day are infringe
good deal OF trouble and worry In the
past could have been avoided had in
ventOrs made a careful study Of the
devices employed I'm making these hui
man bodies Of ours the useful things
they are. The principles OF the block
and pulley or the tackle could have
been discovered ages before had the
files Of natures patent Office been ran
sacked. for there are several complete
pulleys in the body. notably the one
which moves the eyeball inward to-
ward the nose.
Engineers made exhaustive tests and
experiments before they discovered
that a hollow shaft or rod Of iron or
steel is about twice as strong as
solid one. Yet nature had patented
this device in our bones since the birth
Of Adam ana Eve. and every impor-
tant bone is practically constructed on
this principle The ball and socket OF
the hip bones We're the forerunners OF
the modern bail bearings. and IL was
the first automatic oiling machine used
In the world. The value OF air pres
sure and = vacuum was unknown 10
man until the last century. but every
one OF Us carried the secret in the air

hold our LEGS upright IN position.
Engineer have made wonderful
progress i'm developing compound sue

principles contained I'm them are found
In the heart and this little pumping
machine is still without rival I'm the

The principles OF the safety valve
for steam engines are not SO new rs
they seem. our human bodies carry
with them the first automatic safety
valves ever designed There are uu-
ward OF 100000 Of them. We call
them Iy the common name of sweat
glands. Each such little gland has
safety valve which lets off heat from
the body when ii gets beyond 4 safe

Adams apple was the first storage

The eye has a score OF small invcn-
lions worthy Of recording. the ear

organs an equal number. There is the

which we swallow. But there Is even

the mouth. Millions OF microbes are
destroyed in the mouth daily by the
juices elaborated there for this very
purpose. II il was not FOR these three
quarantine stations working continu-
ouSly night and day, we should be kill

In the ear there is little device
which might have Dceu the original OF
our modern compressed air inventions.
The delicate drum of the ear must have
IN equal pressure from the outside and
inside Ia receive and transmit the
sound vibrations. To make this pos
sibie the eU>tachian tube was devised.
Its function IS 70 regulate the air pres
