What Folks are Made of.

The number of bones in a human body
is generally estimated at 245, of which
there are Ieckoned in the skull, head and
face, 81; in the trunk, 81; in the arms and
hands, go; and in the legs and feet, 60.
The weight of the skeleton is about one
tenth the weight of the whole body.
Bone, when used as lever, is % times
as strong as sandstone, 81 times as strong
as lead, nearly 224 times as strong as Elm
and Ash, and twice as strong as Box,
Yew and Oak timber
The number of muscles in man is $40,
being more than twice the number of the
bones. The bulk of the body, upon an
average, is equal to cube of little more
than sixteen inches on side, and the
amount of water equals a cube a little
more than fourteen inches on side, or
nearly three-fourths of the body.
An adult drinks about fifteen hundred
pounds of water yearly, and throws off,
through the various waste-gates, nineteen
hundred pounds. The difficulty of &C.
counting for the four hundred pounds
has led some to suppose that the water is
formed in the system by the union of
oxygen and hydrogen.
The salts that have been enumerated are
found in almost every part of the body.
Common salt Chloride of sodium) is
found in every fluid and solid, except
enamel. The whole amount in the hu-
man maj body is ~ grains: 1t serves many

alimentary fanal, the blood and urHne.
The amoun4 of carbonic acid, however,
varies, being from one to three pounds in
twenty-four hours, and the causes of
variation are temperature, age, sex, state
ofhealth or disease, development of the
body, muscular exertion or repose. This
gas (carbonic acid) contains in every 100
pounds % pounds of carbon (charcoaD
and 72 pounds of oxygen (gas). Hence,
the maximum weight of carbon which
escapes in this form from the lungs of
full-grown man is about fifteen ounces in
twenty-four hours.
The average amount of air which
passes in and out of the lungs at each in
spiration and expiration is about 20 cubic
inches; the amount passed through them
in twenty-four hours is about 622, 600
cubic inches, or, as others estimates it,
from 1000 to 5000 gallons every day.
This varies greatly. In the first place,
the lower the temperature the greater the
amount of animal heat to be generated,
and, consequently, the greater the amount
of air to be consumed. Also, person
laboring in the open air breathes more
deeply than one confined to the house.
From a series of 5000 observations made
by DR.. Hutchinson, the following princi-
pie is deduced: For every inch of
stature from five to six feet, eight addi-
tional cubic inches of air are given out at
forced expiration after a full inspira-
tion." That is, if a person five feet six
inches in height can expire 422 cubic
inches, a person five feet seven inches can
expire 430 cubic inches.
The nails of the hand grow about two
fifths of line per week, while those of
the feet require four times that period for
the same amount of growth. Cases are
on record where the nails have been shed
periodically. The time necessary for a
nail to grow its whole length varies from
twelve to twenty weeks. The nails are
| thickest at their most convex portions, in.
stead of their edges; they grow only SO
long as they are cut, and among the liter
ary class of the Chinese, who never cut
their nails, they are said to attain only 8
length of two inches.
In man, the average weight of the brain
is 54 ounces; in females, 45. The aver
age capacity of the crania of Germans
and Anglo-Saxons is 80 cubic inches.
Daniel Webster's Uranium contained 122
cubic inches.
The amount of blood in healthy body
is about eighteen pounds, or ten quarts.
The heart is six inches in length and four
inches in diameter, and beats 20 per min
ute, A, 200 times per hour, 100,S00 times
per day, SO, 722, ,001 times per year, 1866,
440, 900 times in three-score and ten at
each beat 21S ounces of blood are thrown
out of it; l75 ounces per minute, CSC
pounds per hour, 75l tons per day. In
an ordinary life of a man, the heart beats
at least 1900, 600, 600 times, and propels
through the aorta !, SOC, 600 tons of blood.
The amount of gastric juice secreted by
the stomach of a well-fed, grown person
has been estimated at from 60 to so ounces
in twenty-four hours. \ healthy stomach
contains no gastric juice except where
food is taken, and by its contact with the
surface of the mucous membrane excite:
the secreting organs to pour out the gas
trio fluid in the requisite quantity. If tn,
stomach is in healthy condition, and tn,
brain healthy, the quantity of gastri
Juice generated or thrown out will be jus
sufficient for healthy digestion. If tn
!, condition of either organ be impaired, tn
gastric juice secreted may be either de
ficient in quantity or vitiated in quality
