become visible in drops on the skihi


Because in saeh cases it GENERALLY
arises from some violent exercise or ex-
eessiye heat, and is produced too copi-
ouslF and freely to be Immediately alb
sorbed By the atmosphere. bas


Why is q person less apt to catch
cold from being wetted by salt water
than by freshl


50 Becanse water 'imPregnated with salt
eyaPoratess saore slowly thanfresh water,
in consequence of which the heat Of
the Body is more gradually abstracted;
and also because the Saline particles
hava stimulating effect en- the skin. =


Why is the hand better adapted for
applying soap to the face than a towel
or q speRge2 = @ i..ls.,l


Because the handisnot only soft and
smooth, bnt is also endowed with prop
critics which render it capable of i'm
parting gentle friction to the skin,
more efeetuallY than any other agent.


Why should 9 moderately rough
towel be used for drying purposes


Because the skin requires moderate
amount Of friction, which too rongh
towel would exceed, and too soft a one
be inadequate t. produce.


Why should persons not suffer their
bodies to cool previously to going into
a cold bathi


Because the temperature of the body
being lowered, it possesses less nervous
energy to resist the depressing inha-
ences of cold.


Why should sea-bathing not be had
recourse to when the frame is greatly
debilitatedi


Because the organs have become too
feeble to produce that reaction which
gives rise to the glowing warmth On the
surface of the body after immersion.
And hence the shiyering and sense of
ehilliness which persons under such cir
eumstances commonly experience


Why IS the appetite keener by the
seaside than under ordinary cireum-
etances7


Because the unusual degree of exer-
else in the open air, together with the
bathing, augments the amount of in
sensible perspiration, and occasions
greater waste of the body, which must
be proportionately supplied.


Why is a sensation of thirst, especial
ly for the first few days, generally felt
at the seasidei


Because the sea air. impregnates the
atmosphere With saline particles which
are inhaled and communicat,d TO the
blood.


Why is bathing injurious after full
meall


Because the process of digestion re-
quires uniform degree of heat, which
is rendered irregular by the alternste
chill and glow which bathing produces.


Why, when high water occurs in the
afternoon, is the temperature of the
sea much higher than it was at low
water in the morningi


Because the early retiring tide leaves
the sand uncovered, which continues
for many hours to be exposed to the
rays Of the sun. During this period it
acquires considerable degree of heat.
As the tide rises, the particles consti-
tuting the lower stratum of the advanc-
ing thin sheet of water, as they success
sively come into contact with this
heated sand, are warmed, expanded, and
arise to the surface.


Why on a second immersion in the
water, does the body feel colder than
the 6rsti


Because en leaving the bath the sud
den transition to cold and dense me-
dium, creates an effort in the body to
! produce heat or resist cold, and the con-
tinuance of this action, for sometime
after leaving the bath, occasions sec
/ ond immersion to feel colder than the
first.


Why, after cold bathing, should the
clothes be resumed as soon as possible


Because the body is not restored to
its accustomed temperature until it is
clothed, and by exposure to the air is
| liable to become chilled.


Why is violent exereise after bathing
injuriousl


Because the pores of the skin having
been recently cleared, their functions
are thereby stimulated and calculated
to throwof perspiration more copiously
than ordinarily.


d Why Is bathing sometimes succeeded
by headache2


y Because the blood vessels on the sur
! face of the body become contracted b,
tho diminished temperature of tn,

portion of the vital. fluid towards thi
head; but the thick subject of the brail
prevents its interior vessels from bein;
influenced By the variations of the ex
ternal temperature, and hence fullnes
or congestion is caused.


Why, during course of sea-bathing
: 90 the ankles swell and retain tn
mark of, the impressed fngerl


Because the coldness of the bath oC
casions temporary torpor of the ah
sorbent vessels of the extremities.
