/ Solids, Liquids, and Grease Which Con-
stitute an Average Human Being.
Suppose a man five feet eight inches
high, weighing 15i pounds, had been
passed through the chemists laboratory
aud divided and subdivided into his ulti-
mate clements.
! Five of these are gases and eight solid
substances. The oxygen is shown in a
jar with a label which states that the
weight of oxygen in a man weighing 100
pounds is ninety pounds. The jar,
which viii hold about a gallon, repre-
sents only one ten thousandth part Of the
oxygen of man of that weight. If the
ninety-seven pounds of oxygen were set
free from the body it would fill a space
of /, 900 cubic feet The oxygen is the
great supporter of combustion in the sys-
tenn.
The next jar represents the fifteen
pounds OF hydrogen going 10 make Up
the 154-pound man. This amount OF las
drogen set free would fill 2, $50 cubic
feet and the jar represents only one ten.
thousandth Of the whole amount.
Another jar or bottle, having copac-
ity of little over a quart, represent
the three pounds and thirteen ounces 0f
nitrogen found in the imaginary man.
This nitrogen, if free, would fill 4S.S
cubic feet.
Another small bottle contains, com
bined with calcium, the 3.5 ounces OF
huorine.
Another jar contains one tenth Of the
four ounces of chlorine 10 be found in
the man. Chlorine is one Of the consti-
tuents Of bleaching powder. After the
jar of chlorine was put in the case tho
stopper was blown out and the gas
bleached all the tinted labels in the case.
The carbon is represented by a solid
cube of charcoal weighing thirty-one
pounds
The 154-pound man yields one pound
and twelve ounces of phosphorus, and
three-flth ounces of sulphur.
After the gasses, the carbon, the pho5-
phorus and sulphur have been extracted
from the man there is nothing left Of
him but metals.
First there is iron, Of which the
average m2n described carries one-tenth
of an ounce in his system. This quantity
is shown in the exhibit in the form of
iron wire.
The metal with which the body Is most
abundantly provided is calcium, the basis
of lime, of which the man, supposed to
have been resolved into his chemical con-
stituents, yielded three pounds and thir-
teen ounces. This is "a yellowish metal,
and the amount obtained is shown IN
tube about three inches high.
A little block of magnesium, a silver
hued metal, weighing 1.s ounces, and
then 2S ounces Of potassium were taken
from the man, and all that remained was
a little quantity of sodium weighing 2.6
ounces.
The weight of the chemical eIemenG
in the body of man weighing iJt
pounds are summarized on one of the
labels as follows: Oxygen 97.20 pound.
carbon 31.10, hydrogen 1920, nitrog
1880, calcium $50, phosphorus 1.lj.
chlorine .25, huorine 81, sulphur %
potassium rs, sodium .16, magnesium
II, iron .O1. Total, 154 pounds.
These clements are chemically COM
bined with each other, forming numer-
Gus compounds, and another series IN thu
same class represents the results OBJ
tanned by resolving another 154-pound
man into his principal chemical COM
pounds.
First there are two large jars Of water,
containing together ninety-six pounds or
forty-six quarts.
Then another large jar represents the
proteine compounds, of which the man
yielded twenty-four pounds.
The next in order of quantity are the
fats, weighing twenty-three pounds; the
mineral salts, weighing ten pounds thir-
teen ounces, and the carbohydrates,
starch and sugar, weighing three
ounces.
Among the proteine compounds ap-
pears. homoglobin the red coloring mat
ter Of the blood, and which serves Co
carry and distribute the oxygen from
the lungs to the different parts Of tlle
body.
Two little vials contain protagon and
lecithin, substances found in the brain,
spinal cord and nerves.
There is a pound Of carbonate of lime,
eight and one-half ounces of phosphate
of lime, seven ounces Of huoride Of cali
cium, six ounces of phosphate of mas.
nesia, six ounces Of chloride OF sodium,
five ounces of chloride of potassium.
