sed by great heat or severe exercise is evol-
we'd in much greater quantity; and by ac-
cumulation ot the surface it becomes visible,
and forms sweat. In this way, robust
man may lose two or three pounds weight

and if this be suddenly checked, the conse-
quenccs in certain states of the system arc
often of the most serious description
When the surface of the body is chilled by
| cold, the blood.vessels Of the skin become
contracted in their diameter, and hinder the
free entrance of the red particles of the
blood, which are therefore of necessity COL
lected and retained in greater quantity in the
internal organs, where the heat varies very
little. The skin consequently becomes pale,
and its papillD contract, forming by Their
erection what is called the goose's skin. In
this state it becomes less fit for its uses;
the sense Of touch can no longer nicely dis
criminate the qualities Of bodies, and a cut
or bruisc may be received with compare.
lively little pain. From the oppression Of
two much blood, the internal organs on the
other hand, work heavily: the mental tacul-
ties arc weakened, sleepiness is induced, re.
spiration is oppressed, the circulation lam
guishcs, and digestion ceases; and If the
cold be very intense, the vital functions are
at last extinguished without pain, and with
out struggle. This is picture OF the
extremes; but the same causes which IN an
aggravated form occasions death produce,
when applied in minor degree, effects G.
qually certain, although not equally marked
or speedy in their appearance.
1t is probable that the composition Of the
perspiration varies both ut different ages
and on different parts Of the skin, as is pre-
sumable Som the peculiarly of odor which
it exhales in some situations. The armpits,
the groins, the forehead, the hands, and the
feet perspirc most readily, in consequence of
their receiving proportionally larger sup
ply of blood. Every thing tends to show
that pcrspiration is direct product of vi.
tai process, and not mere exudation OF
watery particles through the pores Of the
skin.
Taking even the lowest estimate OF La
yoisicr, we find the skin endowed with the
important charge Of removing from the sys-
TEN about twenty ounces of waste matter
every twenty-four hours; and when we
consider that the quantity not only is great,
but is sent forth in SO divided a state as to
be invisible to the eye, and that the whole of
tits given out by the very minute ramitica-
tons of the blood.vcssels Of the skin, we
perceive at once why these are so very nu.
mcrous that pins point cannot touch any
spot without piercing them; and we see an
ample reason why checked persplranon
should prove so detrimental 10 heahn,-pe-
cause for every twenty-four hours during
which such state continues we must either
have twenty ounces of useless matter accu-
mulating in the body, Or have some of the
other organs of excretion grievousy over
tasked, which obviously cunnot happen with
out disturbing their regularity and wel'belng.
People know the fact and wonder that 1t
should be so, that cold applied to the skin,
or continued exposure in cold day, often
produces a bowel complaint, severe cold
in the chest, or inflammation of some inter-
nal organ but were they taught, as they
ought to be, the structure and uses OF Their
own bodies, they would rather wonder that
it did not always produce one OF these ef'
fects.
