LARD AS UNaUENT is well known
that rubbing the. body with hOg's fat
has the effect of reducing the 'tempera-
ture of the skin in S 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 recomenlls to incorporate one or
two grammes of carbolic acid into one
hundred grammes of lard, and, with
this, to rub the whole body excepting
the head, two or three times day, &C
cording to the intensity of inflammation
characterizing the case in hand. The
| 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 poisnous nature of copper,
and, to less degree, of tin, makes the
following method Of testing for them in
aa extract, as described by Hager, both
| interesting and useful, for either of
these metals may have been dissolved
| from the walls of the vessel i'll which it
was prepared. "The extract is, for
! for this purpose, dissolved in five parts
OF water, or very dilute spirits, and
slightly acidifed with a 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 will 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
flame, and the copper will 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 a test glass
and five to eight drops Of nitric acid
added. It is carefully DO led until entire
Iy dissolved, when seventy-fve drops OF
ammonia is added, the solution shaken
and allowed to settle. If tin is present,
it will separate as arnOrphous oxide OF
tint in white flakes. . .-..-----.-..-.-
SAND AND Mud BATHS. of sand

less deserved, for centuries; and at the
present day are employed to a considera-
BILE extent in different parts of the world.
