supply of oxygen, we obtain the heat
given out during its oxidation or com
bustion. f11vinter, when we takeex-
ercise in a cold atmosphere, and when,
consequently, the amount of inspired
oxygen increases, the necessity for food
containing carbon and hydrogen in
creases in the same ratio; and by graf
flying the appetite thus excited, we oh
tain the most efficient protection a.
gainst the most piercing cold. A star
wing man is soon frozen TO death; and
every one knows that the animals Of
prey in the Arctic regions far exceed
in voracity those Of the torrid zone
Our clothing is merely an equivalent
for a certain amount of food. The more
warmly we are clothed, the less urgent
becomes the appetite for. food; because
the loss Of heat by cooling, and, conse-
quently, the amount Of heat to be sup
piled by food, is diminished. If we
were to go naked, like certain savage
| tribes-or if, in hunting or fishing, we
were exposed to the same degree Of
cold as the Synoyedes, We should be
able, with ease TO consume ten pounds
Of flesh, and perhaps a dozen Of tai
low candles into the bargain, daily, as
warmly-clad travellers hayerelated with
establishment of these people. We
should then also be able to take the
same quantity Of brandy OR train oil
without bad effects, because the carbon
and hydrogen of these substances would
only suffice to keep up the equilibrium
I between the external temperature and
that of our bodies. The Englishman
in Jamaica sees with regret the disap-
pearance Of his appetite, previously a
source of frequently-recurring enjoy
ment; and he succeeds, BY the use OF
Cayenne pepper, and the most power
full stimulants, in enabling himself to
swallow as much food as he was accus-
toned to take at home, But the whole
Of the carbon thus introduced into the
system is not consumed; the tempera-
Iture of the air is too high, and the op-
prcssiye heat does not allow HIM tom
crease the number Of resplratlons By
active exercise, and thus to proportions
the waste to the amount Of food taken.
{ Disease of some kind, therefore, en-
sues. On the other hand, England
sends her sick-whose diSeaseddlges-
live organs have III a greater or less de-
gree lost the power Of bringing the
, food into that state in which tits best
adapted for oxidation, and, therefore,
furnish less resistance to the oxldlzing
agency OF the atmosphere, than IS re-
CURED in. their native climate-to
! Southern regions, where Che amount
Of inspired oxygen IS diminished IN so
great a proportions; and the result, an
improvement in health, is Obvious
The diseased organs of digestion have
sufficient power to place the diminished
amount of foodin equilibrium with the
inspired oxygen; in the colder climate,
.4he organs of respiration themselves
would have been consumed IN furnish
inc the necessary resistance to the acT
ton of the atmospheric oxygen. In
our climate, pepatic diseases, or those
arising from excess Of carbon, prevail
III sumner; in winter, pulmomc dis
eases, or those arising from excess OF
oxygen, are more frequent. The cool
ING Of the body, by whatever cause 1t
may be produced, increases the amount
of food necessary. The mere expo
sure to the open ,ir7 in aocarriage or on
the deck of ship, by increasing radI-
alton or vaporation, increases the loss
ofheat, and compels Us TO eat more than
usual. The same is true of those who
are accustomed to drinl, large quaint
ties ofcold water, which is given oil at
the temperature Of the body, $50
It increases the appetite, and persons
of weak constitution find it necessary,
by continued exercise, to supply TO the
system the oxygen required to restore
the heat distracted by the cold water.
Loud and long continued speaking,
| the crying of infants, moist air-all eX-
ert a decided and appreciable influence
on the amount of food which is taken.
