100 pounds from 90 to % pounds are
I simple water, this being enough 10 MI

( main purpose is somewhat curious. Inc
greater part OF the bone and fat that
/ make up the body are what might be
+ termed lneless tissue. The lance
| that makes the body aive is prolopiasm
/ which exists in the shape oi mlI ions ol
minute glObules These globules could
no more live ont OF water than could %
shoal of fish. The more water there IS

] Iron is another substance that has an
/ important part TO play for without Il
/ the oxygen could not pass from the lungs
/ tO the remote parts Of the body. The
I amount Of iron I'm evidence, however IS
{ very small. scarcely more than is grains.
I or about enough TO make four or hVe
good-slzed tacks.
Ordinary table salt. which is n mix
| ture Of sodium and gaseous chlorine IS
quite necessary 20 the welfare of the
body. IL being found in both fluid and
, solid substances. I'm spite Of this how
ever. there are not more than six or sew
en- ounces In the whole body, or little
more than enough 20 supply n dining
table of a gOod-sized boarding house
Small as this supply Is the body is eX-
travagant I'm its use and loses half an
ounce every day. Another Substance Of
which there IS but small amount i'm
the body bat that does Il large amount Of
work is washing soda. or sodium in union
/ with carbon and oxygen It's mission in
! the body is to act as scavenser. Dissolv-
cd I'm the blood 10 travels from one part
OF the anatomy to the other and whcr-
ever 70 finds a particle Of carboulc acid
II SEXES upon 80 and carries 1t TO the
lungs from which IL IL discharged into
the air This carbonlc acid, poisonous
as II is IS also a necessity but If II was
not quickly removed it would clog the
machinery and death would follow.
Among the trining substances without
which existence would be impossible are
chloride Of ammonia. chlOrate OF potash
and hydrochloric acid. the latter being
the substance that kills most OF the mi
CrObcs I'm the food we eat, that prevents
fermentation and assists digestion.
Starch and fat produce fuel for the
body and this fuel is consumed at once
or Is held in reserve as need may require.
Most of the fat that IS eaten meets am
alkau i'm the intestincs and thus soap IS
made. There is enough fat in the BODY
TO make from "a TO 10 pounds of
candles. and the average man manufac-
lures tons of soap during ~is lifetime.
There is scarcely an occasion when he
does not have what would De equal TO a
large cake Of soap concealed about his
internal organs. and. as i'm every we'll
organized soap factory. ne manufacture
"a large quantity Of glycerine as a by
product.
Another important constituents Of the
body is starch. In the intoetincs lit
tie water is added and the starch becomes
sugar in which condition sc goes into the
blood. 1t is estimated that there ls all
ways enough sugar in the body TO nl a
large-sizcd bowl.
These are but a few Of the compound
that may be found I'm the human struc-
ture ard similar remarkable compari-
sons may be made I'm regard 20 his cn-
ergy. One of the most astonishing facts
IS that man Is not crushed 20 death be-
fore he takes his first step because he SIS
always carrying load that would break
the backs of seventy horses Strange ~
this assertion may seem IT IS a matter
that may easily be proved 10y mathemau-
clans. IL Is matter OF general knOwl-
edge that the pressure OF the atmosphere
at sea-level is ID pounds 10 the square
inch. The skin area Of the average man
is about 300 square inches so &c is a
simple problem 10 figure out the result
AT each step ne carries an external load
of nearly seventeen tons The reason
why he SIS not crushed as lat NJ the flat
test pancake by this enormous burden is
due 90 the fact that the internal Iles-
sure I'm the lungs as well as the expansive
forces Of the gases of which his body IS
so largely composed are sufficient 70
cOunterpoise the external pressure
Another fact that is not generally
known is that the average man produces
eight ounces of pure charcoal every dax
of his life. In the course Of The twenty
four hours he will breathe ont about u
90 grains of carbonic acid and this. If
the oxygen should be removed. would
produce the coal. and this leads mp TO
one of the most interesting of the OK
amples. The normal capacity of the
lungs is 220 cubic inches residual air
occupying 100 inches. complementa afr
loo inches. and 20 inches are tidal air
The average man breathcs from fifteen
20 seventeen times a minute. BY doing
this he eNerts a force that. II concontrat-
cd I'm "A single effort would enable him %
support on his chest a ulock ~ iron
weighing nearly 1000 pounds. while the
amount OF air used by the Inspirations
and expirations would be sufficient 10

HEART a POWERFUL ENGINE.
Tho heart is just as powerful as the
lungs. and the amount NJ energy It de-
velops is simply astounding. During the
twenty-four hours this vital engine pro
duces energy aggregating l20 foot tons.
or. in other words. power sufficient 10

earth and 10 requires but q little calcu
lotcn 90 show that during the day this
NtCo purlp of nerves and muscles does

would enable a man 10 stand on shore
and drag three Geo ton ships at a speed
ot SIX knots. or 10 carry 200 pounds Of
coal 90 the top OF a tower 40 feet hign
such comparisons could be carried on
Indefinitely but these are sufficient 20
prove that there is nothing more wonder
fully constructed or powerful than this
strange machine that we term the human
body.
