Scientific Facts and Principles.

practical article, which should be generally
read. We make the following brief ex-
| tracts:
All human beings are so constituted that
while some parts may be temporarily be-
numbered with cold without danger, the
blood that circulates through the heart and
through the system generally, must be
maintained uniformly at just about 981o of
temperature (9S!o Fahrenheit, or 80 cen
tigrade.) If the heat Of the blood rises or
| falls only or I degrees from this normal
point, and continues so, fatal results are ex-
peeted. Every degree that disease elevates
the general internal heat above 1902, is a
rapid approach towards the danger point,
and when only 1862 is reached, the most
skillful efforts of physicians are usually
needed to save life. On the contrary, even
in the coolest regions where the thermom-
eter marks 600 or 70o, or more, below the
freezing point, the internal heat mast be
kept up, and if it falls only from $50 to
94o or 93o. and continues thus, there is
great danger that the wheels of life will
stop. These are general statements, ap-
plieable to healthy condition. Cases
have been reported where in tetanus or
lockjaw the temperature rose 20 nearly
II1e, while in asthma it sunk to 7S0, and
in cholera TO 67o
When the oxygen OF the air unites with
the carbon of hard coal or charcoal, or of
wood. or Of -four. meat, or Of any other
food, compound Is formed, viz, gas
which we can Carbonie Acid. The process
of forming this compound sets at liberty
heat which was before entirely concealed,
or which existed in another form, and when
coal or weed Is burned rapidly We have a
hot IRE. The same process goes on when
wood rots away. but the heat is developed
30 slowly that we do not notice il.

The blood carries the heat sothe surface

and good deal Of heat escapes of into the
air. Ii the air Is cold this escape IS more
rapid. and more heat must be produced

more fuel, that i mere food, Or more 5eSh
is consumed. Remember that the blood

then, in cold weather more food is necessa-

all help to stop this waste Of hat.
As to domestic animals, IS not the above
positive proof, that sheltering all animals
from cold weather, from chilling winds
which by their rapid motion carry of heat
more rapidly, Is the way to save food and
to save waste Of flesh2 Ifby stopping this
waste Of heat from the surface all the food
consumed win not be wanted to make heat,
a portion of IT can 60 to increasing the
flesh, that Is to producing growth, or more
can be used in making milk, aggs, etc,
within the animal.
Dsspepsie persons, those having feeble
digestion, or poor appetite, get less inter
nal heat from food combustion, and suffer
from cold. Such persons need warmer
atmosphere. or warmer dwellings,, and warm
er clolhing to retain the heat that is pro
dueed. This applies to all animals,
Close-itting garments, gsrters, lacing,
boots, shoes, neck-tics, etc, that prevent
free easy circulation Of the blood, each aud
all diminish the amount of heat produced,
and its uniform distribution. Exercise
promotes more rapid circulation Of the
blood and increased heat production.
Green wood, besides its Inconvenience,
is very Improbable A large amount Of
heat which the dry portions would yield, is
lost BY being carried off in the evaporation
of the sap. SO Of any wet or damp fuel Of
any kind.
We stated above that evaporation Of
water carries off much heat Rubbing wet
horses and other animals dry is very useful
not only to save heat, but also to save cold
taking. For the same reason any damp
garments should be replaced with dry ones
as soon as possible, or enough covering be
added to prevent chilliness from the evap-
oration.
As confined air is poor conductor of
heat, all fabrics that are porous, that i fAll
of little interstiees, tubes af hples flled with
air, are the best protectors to keep heat
