wHAT MAKES A MAN.


stitutc an Average Human Being.
Suppose a man fvo feet eight inches
high, weighing 1H pounds, had been
passed through the chemists laboratory
and divided and subdivided into his ulti-
mate elements.
Five Of these are gases and eight solid
substances. The oxygen Is shown in a
jar with q label which states that the
weight OF oxygen in a man weighing $50
pounds is ninety-seven pounds. The jar,
which will hold about a gallon, repre-
SCENTS only one ten thousandth part Of the
oxygen OF q man of hat weight. II the
ninety-seven pounds Of oxygen were set
free from the body it would fill a space
of 1000 cubic feet. The oxygen is the
great supporter Of combustion in the sys-
tem.
The next jar represents the fifteen
pounds OF hydrogen going TO make up
the 154-pound a This amount Of by
drogen SGT free would fill 2.750 cubic
feet. and the jar represents only one ten
thousandth OF the whole amount.
Another jar or bottle. having q capac-
ity of a little over a quart, represents
the three pounds and thirteen ounces of
nitrogen found in the imaginary
This nitrogen, if free, would fill 48.3
cubic feet.
Another small bottle contains, COM
bined with calcium. the $50 ounces OF
huorine.
Another jar contains one tenth Of the
four ounces of chlorine to be found in
the man. Chlorine Is one of tho 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.
Tho 154-pound man yields one pound
and twelve ounces Of phosphorus, and
three-ffth ounces Of sulphur.
After the gases, the carbon. the phos-
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 mar 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
a~bundantly 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 a
tube about three inches high.
A little block OF magnesium, a silver
hued metal, weighing 1.S ounces, and
then e.8 ounces of potassium were taken
from the man, and all that remained was
a little quantity OF sodium weighing go
ounces.
The weight of the chemical elements
in the body Of a man weighing 1874
pounds are summarized on one of the
labels as follows: Oxygen 1920 pounds.
carbon 81. 10, hydrogen 1920, nitrogen
1880, calcium $50, phosphorus 1.75,
chlorine 80, 1uorine .22, sulphur 30.
potassium .1S, sodium IS, magnesium
IL, iron .01. Total, 154 pounds.
These elements are chemically COM
bined with each other. forming numer-
Gus compounds. and another series in the
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 nj ty-six pounds or
forty-six quarts.
Then another large jar represents the
proteine compounds, Of which the man
yielded t~wenty-four pounds.
The mex 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 up
pears homoglobin, the red coloring mat
ter of the blood, and which serves to
carry and distribute the oxygen from
the lungs to the different parts of the
body.
Two little walls contain p~rotagon and
lecithin. substances found in the brain,
spinal cord and nerves.
There is a pound of carbonate Of lime,
eight and one-hnlf ounces of phosphate
of lime, seven ounces of luoride of cal
cium, six ounces of phosphate of mag
nesia, six ounces of chloride of sodium.
five ounces of chloride of potassium,
that exhausted the man with which the
chemist started. -Scientifc Exchange.
