Why do Paints Dry 7
II m provd long ago, that llneeed oil, when
exposed to th lr, becamo covered with bard
emit, uil that tbla omit 1 produced Jby the
absorption of oxygen, Paint mads (ram oil
and coloring muter alone doe not dry because
it parts with any thing or because it gives off
j T'l ,r' ou Pv" i neoomes Hard by
he action of the atmosphere. It U stated
in a recent work1 on painta that oil does
not form even the basis of a paint. , Thia la
'more technical than Judicious. Oil alone, if
laid on in thin, sucoessivt coat, beoomea Terj
.hard and forma a durable and impervloue v
slab, which protecu the wood beneath almoat
aa well aa paint wonld do, at leaat ao far aa
molturs and air are oonoerned. Againat the
aun'e raja, howerer, it la a poor defenae, lint
aa it haa been fonnd Impossible to apply a sui
flclent coat of thia Tarnlah lu any thing like a
resaonsble time, the oil haa in general been
miied with Tarioaa colored powder on pig
menta, which thicken it and thai enable ua to
lay on a heavier coal. Man; of tbeae pigments
hare no action on the oil, and it ia alwaja
beat that they ahonld hare so action.
Compound! of lead, which are known to
form chemical compound with the oil, are
among! the Terr poorest palnta. White lead
ia confessedly one of the leaat efficient of all
our preservative agents, tha authority referred
to to the contrary notwithstanding.
When paint la applied toafreah surface of
wood, it often appear to dry In a abort lltno.
In thia caae. however, it will be found that the
paint baa. not really dried, but that the oil baa
been absorbed by the wood; and In thia case
the pigment la often left In the form of a fria
ble powder, loosely adherent to the aurface to
which It was applied. It rub off Terr easily.
Tblt occur to a lea extent with white lead
than with any other paint, (Imply because the
lead combines with, it oil and holds It on the
auriaoe, tnus preventing It sinking in. .We are
inclined to regard thia feature aa one which con
fers no advantage upon whtU lead. It la proba
bly bet ter for th wood that a much oil aa possi
ble ahould soak into It, and it ia no great disad
vantage that the paint of tha first coat ahould
not adhere strongly. Where economy ia an ob
ject, the absorption of the oil Is prevented by
first applying a coat of cheap siring.. The size
fill up the pores of tha wood, aud prevents the
ainkiug in of the oil. For in-door work, this
anawera very well, but for out-door purposes it
ia objectionable,
, put all paints do not dry n the manner that
we have mentioned. For in-door work, where
i( ia desirable, that the paint ahould dry rapidly
and have a dead or non-reflecting aurface,
f taint la generally miied with turpentine. Thia
a volatile oil, which passe off rapidly when
expoaed to the air, and thus leavea the paint
behind a a thin crust. This ability of tha
Ealnt to resist atmoapheria Influence is there
y lessened; and this, for in-door work, I a
matter of no consequence. It would be wrong,
'perhaps, to aay that the oil of turpentine
passe off entirely by evaporation, aa a amall
'portion probably beoomea oxidated and re
mains behind. The amount ao retained la,
however, very email. Amtrtcan llomtstead.
A New WxATncn Vim. Th old weather
cock baa two essential fanlta; it indicatea a di
rection when then la a dead calm. It gives no
mean of learning the force of th wind; while
it falia to show the true course of the aame, by
exhibiting merely ila horizontal component.
SI. Tany proposes the arrangement to be at
tached to the ordinary lightning rod. Just
above a suitable shoulder on the latter ia placed
a copper ring, grooved and made into a pulley
easily rotated In a horizontal plane. Around
thia paaee a knotted oord, the end of which
are secured to the extremities of a short stick
or metal rod, to which ia secured a simple
treamer. Thus constructed the vane indicatea
a calm by falling vertically, and beaidea shows
the strength of the wind by being blown out
more or less from th lightning rod, A I ev
ident, it ia capable of motion in every direc
tion, so that if then exist In the wind an upward
tending vertical component, the aame will be
shown.

New Way ol Coloring Metal.
It ia announced that metal may be colored
quickly and cheaply by forming on their aur
face a coating of a thin film of a sulphide. So
for luatanoe bras article may be thus in five
minute coated with any color varying from
gold to copper red, then to carmine, dark red,
and from light anllln blue to a bin white, like
ulphid of lead, and at last a reddlah white,

depend on the length of time th metal re

Qooo HBV-TH
Catching Cold.
Catching cold I "a easy as lying." but to
explain th pathology thereof Is by no mesne
so readily don. In fact, nntll th reoent re-
earche of Dr. Rossnthsl, whose work on th
subject Is attracting much notlo In Europe,
almost nothing was known about it except the
mere fact that th ailment popularly ascribed
to "cold' are liable to oocur after th body, or
some part of it, has been snddcnlycblllrd, that
Is, cooled below th normsl temperature.
There are two factor ooncerned In thia chilling
process; the nature of th external medium
suoh a air or water in contact with the body;
and the condition of the blood-veasela.
. Dry air baa very little power to abstract bout,
if it be still; but a slight wind, from tha coo
slant contact of fresh particles of cold air on
th surface of the body, soon carrlra off its
heat. It, then is much moisture combined,'
th chilling effect reacbe It maximum. Ex
perience baa abown that It I not ao much the
abaotuie lowness of temperature which gives
rise to colds, as sudden changes from a higher
to a lower. The reason of thia waa not under
stood until Dr. Iloaenthal explained It. Whon
the aurfac of a healthy animal la exposed to
cold the cutaneous vessels contract, and by
thus confining th blood to th interior of the
body, prevent it eoollng, and pruerve the
temperature of th vital organ, unless the so
plication of oold b continued for a consider
able time. Thi is not lha caae, however, when
tha aaltnal ha been previously expoaed to
warmth. The outaueoue vessels beoonie para
lysed by the hut, and remain dilated even
after th oold ha been applied. The blood ia
thua exposed over a large aurfaoe and become
rapidly cooled, even though the temperature
fo the surrounding tnediam is not very low.
In Rosenthal' experiments, animala were
kept from 07 to 10 degree F. The tempera
tare of th animal themaelvea quickly rose
during their confinement to 111 or 113 degree.
After their removal it not only aank to the nor
mal temperature, but even below It, ao that an
animal which was from 108 to 111 degree In
lb warming apparatus fell to 00.8 degrees, and
remained at that for several days, although the
room in which it was kept was moderately warm.
Confinement in a close office, bot theater, or
crowded ball-room, will have a similar affect on
man. From auch place, people pasa out into
the cool, open alr.or sometimes evenpurposely
station themaelvea In a draught. The blood,
which is coursing through the dilated vesaelsof
every part of the surface, is rapidly cooled, and,
on it return to the internal organs, cools them
much more quickly than It could have done had
lha person almnlv been ex nosed to coldwlthoui
dilatation of the vesaela ly previous warmth
Iloaenthal lays much stress on the creel effect
of audden cooling In bringing on a cold, the
sudden change In the teraiwrsture of the blood
producing sn Irritating effect, and Inducing in
namatlon in auy weak organ in a way that a
gradual alteration would not do. It would
aeem, however, that lb alteration mast be
from a temperature above to one below the
normal temperature of th blood,-and not a
mere reduction from one considerably above
the normal to one at or near it. '
When much heated we may staud for a abort
time In a cool atmosphere with impunity ; but
if we atand long enough to produce a ahlver,
we inn a great risk of catching cold. The fact
that it ia more dangerous to sit for a long time
in wet clothes, appears to Indicate that a con
alderabla aud more gradual cooling, auch aa
may then occur will produce aimilar effects to
a alight cooling suddenly effected by exposure
to a oold draught after being in a chill, in caus
ing lnflammaUocs may be partly due to the ef
fect of cold on th tissue themaelvea, and
partly to th congestion which will occur in
some parts when th blood ia driven out of
others by the contraction of their vessels,
Rosenthal 1 Inclined to ascribe the chief power
to the former cause. Everybody know tha
beneficial Sect of oold bathe, sold sponging,
t., in "hardening " person, a it is termed,
so that they are able to face almost any weather
and to endure audden change of temperature
without Injury. Iloaenthal considers that the
frequent application of cold water or cool air
increaaea the lone of th cutaneous vessels, si
that they do not become so much relaxed by
heat aa to be unable to contract with sufficient
force when necessary. Tha Dower of reaulatins
th temperature ia ihot preserved, and ibe per
son prevented from catching cold. Journal of
