majesty's own fuel In truth the gentleman
down below ought TO find plenty of material
for burning the sinners he desires to touch
match to. The very economy of the body de-
pends upon combustion, the after products Of
digestion being taken up by the blood and
passed through the lungs, where they come in
contact with the oxygen in the atmosphere and
are burned up by process, though chemical
panied by fame. The only difference is that
the sort of combustion described is slower.
Having found out precisely what a man Of
average weight is made of is is next worth
while to determine how he maintains a uni
form weight by balancing his daily expenditure
Of wastes with his daily income of food. &c.
inns Is shown In another glass case. To begin
with, such human being needs q daily income
OF "a ounces OF nutritive substances, ii ounces
OF water and 80 ounces of oxygen. The nutri-
Abumen makes blood, muscle and skin: fat
and sugar are consumed as fuel to keep the
body warm
BALANCING THE ACCOUNT.
All this is exhibited in a series Of glass Jars,
the first Of which contains the necessary four
and one-ffth ounces of sh-forming albumen.
represented by that much white of egg. The
next jar contains two ounces of pure fat
enough to make q fair-sized candle So much
of that material your system must assimilate
each day. In third jar are 171S ounces OF sugar
and starch. little vial holds four-ffths of an
ounce OF the needed mineral matter, such as
common salt and phosphates Of sodium and
potassium, DC. Such matter is contained in
various foods which one eats. In still another
jar are two quarts Of water, while the l59 gal
Ions OF oxygen required are represented by one
one-thousandth part Of that quantity of the gas
receptacle
In a glass case adjoining the corresponding
daily expenditure Of the man is shown. FIRST,
there is a jar containing two and one-third
quarts OF water. This seems surprising mas
mucn as only two quarts were taken into the
body; but the difference is made up by water
derived from the decomposition of foods in the
Dooy. tits an interesting fact that nearly one
half OF the water required is taken into the
system in shape Of foods, 81 ounces of it being
drunk and 30 ounces eaten in bread and other
things. Other jars in the case contain a rep
resentative fraction Of $50 gallons of carbonic
acid. which is nearly all made by the oxidation
OF carbon in the lungs and is expelled in the
breath; also a small quantity of white crystal
lized substance called 'urea," and the same old
four-ffths Of an ounce of mineral matter.
NUTRITIOUS FOOD.
Colored picture cards in these last two
cases show the amount Of nutritive properties
contained by various food From them one is
surprised to learn that eggs, a single one of
! which ID popularity supposed to contain
much nutriment rs pound of beefsteak, are
4O per cent less nutritious than the latter
article, pound for pound. More surprising
still, beef sirlon is Is per cent less nutritious
than beans and peas, while chicken and turkey
are actually trife ahead Of these two vege-
tables, being thus the most nutritive Of foods
known. Fresh mackerel or shad is about as
nutritious as sirloin steak. Oysters are just
one-halt rs nutritious eggs, pound for pound.
and milk one-third nutritious, quantity for
quantity. To exactly supply what he needs the
man Of l54 pounds weight should eat each day
20-ounce loaf of bread. an S-ounce slice of
