in medulla or heart nerves, between heart
and brain. Why singing and roaring of ears in heart diseases, if there
is no waste of pectoral electricity?

THE HEART.

With the knife of reason in hand and the microscope of mind of the
greatest known power properly adjusted, we cut and lay open the breast
of man. Here we dwell indefinitely. This is the engine of life, the
self-propelling machine which has constructed all that is necessary to
its own convenience and comfort. It has brought and deposited its own
nourishment in the coronary arteries, whose duty is to construct and
enlarge the heart from time to time as its demands increase. We see its
main trunk of supply placed lengthways with the spinal column for the
purpose of constructing a manufactory of nutriment. We pass from the
heart upward about one foot, here we find it has constructed a battery
of force and sensation, and contains all power necessary to carry on
construction to the completed man.

In that brain or battery is found all the motor and sensory elements of
life, with nerves to transmit all nerve powers and principles found in
the human body. There is not a known atom in the whole human make-up
that has not been propelled by the heart through the channels by which
it has provided for such purpose. Every muscle, bone, hair, and all
other parts without an exception have traveled through this system of
arteries to their separate destinations. All are indebted to the heart
for their material size, and all qualities of motion and life sustaining
principles of the human body.

If the carotid artery should tire out and not be able to perform its
duty the brain would tire out also, and cease to operate. Should the
descending aorta come to a halt from any cause, all parts of the body
depending upon that vessel would suffer a total loss of blood supply.
Equally so with any other principal artery of limb or body, all mark a
failure equal to the suspended supply. The parts and principles of the
human body depending upon the heart are numerous beyond computation.
Every expulsive stroke of the heart throws into line armed and equipped
for duty thousands and millions of operators, whose duties are to
inspect, repair injuries and construct anew if need be from the crown of
the head to the sole of the foot. With the best eye of reason we see but
dimly into the breast of man which contains the heart, the wonder of man
and the secret of life.
