pOsure to the air this substance, at first
liquid, absorbs oxygen, becomes solid
and transparent, firmly inclosing the
particles Of color. Linseed oil contains
go per cent. Of this incline. By lapse
Of time and physical ana chemical
changes, the incline looses in some de-
gree its Transparency and the picture
fades, those colors containing the least
oil changing most. Pettenkofer has dis
covered that the vapor of alcohol viii
renew the qualities Of the incline, and
he restores old Oh paintings By placing
them over a tight box, in the bottom Of
which IS q flannel cloth, which has been
dampened With alcohol of so per cent
strength. The arrangement should be
such that every part Of the picture will
be exposed to the alcoholic vapor.
LARD As UEsUEST.-It is well known
that rubbing the body with h0g's fat
has the effect Of reducing the tempera-
ture of the skin in arlet fever. A gen
tleman of our acquaintance has used
the fat portion of smoked hams with
beneficial results, and writes TO the edi-
tor to disseminate the fact for Others
benefit. A celebrated German physi-
clan reeomen.ls to incorpcrate one or
two gramnes Of carbolic acid into one
hundred grammes of lard, and, with
this. to rub the whole body excepting
the head, two or three times a day, &C
cording to the intensity of inflammation
al, ook..,
effect of this kind of treatment is to
propuce pleasant feeling of GOODNESS,
to keep the skin softer, and after each
application the temperature of the skin
falls somewhat. The carbolic acid ope-
rates to destroy the germs and spores
of the disease.
Test FOR CoPPER AND Tn IN Ex-
TRACTS The poisnons nature of copper,
and, to a less degree, of tin, makes the
following method of testing for them in
an extract, as described by Hager, both
interesting and useful, for either of
these metals may have been dissolved
from the walls of the vessel in which it
was prepared. IS The extract is, for
for this. purpose, dissolved in five parts
of water, or very dilute spirits, and
slightly acidified with drop or two of
hydrochloric acid A bright strip of
zinc is placed in the solution, and, after
half an hour, if no impurities are pre-
sent, the zinc viii be found as bright
and colo, less as when first put in. If,
however, copper and tin are present,
it Will be coated with brown film;
if tin alone is present, the film
will have q grayish white color. It is
washed with water and dried by heating
the strip of zinc gently in an alcohol
fame, and the copper viii be indicated
by its Well-known copper color. Under
like conditions the film of tin is a dull
grayish white. IF copper and tin are
both present, and it is desired to deter
mine the quantity OF the tin, the film is
peeled off with knife into test glass
and Eve to eight drops of nitric acid
added. It is carefully DO. led until entire
ly dissolved, when seventy five drops of
ammonia is added, the solution shaken
and allowed to settle. If tin is present,
it will separate as amorphous oxide of
tint in white fakes"
SAND AND AIUD BATHS Baths of sand
or mud have had reputation, more or
less deserved, for centuries; and at the
present day are employed TO a considera-
BILE extent in different parts of the world.
By the former, the inhabitants of the
eastern shores of the Mediterranean
expect to cure their rheumatic and
scrofulous troubles The process Of
taking this ''cure is very simple; the
the patient buries himself almost COM
pletely in the hot dry sand, and remains
thus, some time after profuse perspi-
ration has broken out the preparation
is soon followed by a rash upon the
| skin, which subsidies IN a few days.
| The little benefit arising from this cure
is due in the main TO the sweating,
which frees the blood from impurities
through the pores of theskin, which lat
ter is locally irritated and excited to
greater action by direct contact of the
sand. But the latter, the mud baths so
| popular on the continent of Europe,
among which those of Salzburg, Fran
zenbad aud Marienbad in Germany have
the highest reputation, are really more
beneficial. They are prepared in the
following manner; Bog mud is thor.
oughly dried and sifted, then saturated
with mineral water, the mixture being
made so soft that the body can sink
into it; the temperature Is raised to
about 112 degrees Fair, and the bath
is ready. The baths may be either
partial or complete, according 70 the
part of the body to be treated but in
either case, the duration of single
bath is from thirty to fifty MINUTES ;
after which the body is cleansed by a
warm water dossche. They are taken
daily, early in the morning, until relief
is obtained. The diseases to which they
are particularly suitable are some kinds
of paralysis, muscular rh, umatisIn, and
the dull nervous pains which follow Sc
we're bruises and which are called
weather pains. In former times, then
efficacy was thought to depend upon
the large amount of iron and salts con.
tanned in them, and which were absor.
bed into the blood through the pores Of
the skin. twas even supposed that there
existed a magnetic current in the mud
which acted as a strong nervous tonic
but at present the eneral belief is tina
the action is simply that OF universe
