MARvELS OF THE HUMAN BODY

MARVELS UF HE HUMAN RODY
In the human body there are
about 200 bones.
Muscles, about 500. The length
of the alimentary canal is 32 feet.
The amount of blood in an adult
averages Ia pounds, or fully one
tenth of the entire weight. The
heart is six inches in length and
four inches in diameter, and
beats 70 times a minute, 4,20C
times per hour, 36, 1872, 600 times
per year, 2,575, 440, 600 times in
three score years and ten, and at
each beat two and one-half oun-
ces of blood are thrown out of it;
IT'S ounces per minute, CSC pounds
per hour. "a tons per day.
All the blood in the body pass
es through the heart in 3 minutes.
This little organ. by its ceaseless
industry, pumps each day what
is equal to lifting 122 tons one
foot high or one ton 122 feet
high.
The lungs of the average per-
son will contain about one gallon
of air at their usual degree of in
f1ation. We breathe on an aver
age of l, 200 times per hour. The
aggregate surface of the air cells
of the lungs exceeds 200, 600
square inches, an areasof very
nearly equal to the floor of a room
40 feet square.
The average weight of the
brain of an adult male is 3 pounds
q ounces, of a female, 2 pounds
A ounces. The nerves are all
connected with it directly by the
spinal marrow. These nerves,
Lit is stated, with their branches
and minute ramihcations, proba-
bly, exceed 10, 1000, 900 in number,
forming as it were a bodyguard.
The skin Is composed of three
layers, and varies from one
fourth to one-eighth of an inch
in thickness. The atmospheric
pressure being about Ia pounds
to the square inch. a medium
sized person is subjected to a
pressure of 30, 900 pounds. Each
square inch of skin contains 3, SOC
sweating tubes, or perspiratory
pores, each of which may be
likened to a little drain-pipe one
fourth of an inch long, making
an aggregate length irf the entire
surface of the body of 201, 166
feet, or a ditch for draining the
body of almost 40 miles long.
The normal human body has in
Il the iron needed to make 7 large
nails, the fat for IA candles, the
carbon for 65 gross of crayons,
and PHOSPHORUS enough for 800
600 matches, and out of 1t can be
obtained 20 coffee spoons of salt,
so Jumps of sugar. and az liters
of water.
The rods in the retina of the
eye, which are supposed to be
the ultimate recipients of light,
are estimated at $1,000, 900; and
the gray matter of the brain is
huilt nm of at least 600. 600. 00C
cells.
The elements in the human
body, roughly speaking, are oxy-
gen, hydrogen, carbon, and nj
trogen, PHOSPHORUS, calcium,
sulphur, chlorine, sodium (salt)
iron, potassium, magnesium and
silica.
From the mere mechanical
point of view, the makeup" OF
the human frame surpasses in its
perfection of structure, arrange
ment and adaptability to condi'
tions and circumstances, any
other machine in the world.
What man will be 10, 900 years
from now no one can tell; for the
purpose of his coming to earth is
apparently far from being full.
filed, and some of his most awe,
inspiring and Christlike powers
are only now being developed anc
receiving scientific recogni ton.
Truly. as David said:

marvellous are thy works; anC
that my soul knoweth right
