TIM Value OF FRUITS a Foop.-A
contributor to the report Of the Michi-
gan Pathological Society writer: Fruits
directly aid in maintaining the essential
equilibrium in the system. The malic
acid Of apples and kindred fruits, the
tartario acid Of grapes and berries, the
oitrio acid Of lemons, etc., consists
largely Of oxygen, the element of COM
bustion, 80 that when eaten in sufficient
quantity these fruits serve as the heat
producing element. Also the fluids
which they supply aid in carrying
of, through the lungs, skin and kid
neys, the waste Of the system, matter
no less essential to life than is food it.
SELF"
TIE Uses OF THE. LEMoN.-A piece
Of lemon bound upon a corn viii re-
leve it in a day or SO. It should be re-
newed night and morning. The free
use OF lemon-juice and sugar will al.
ways relieve cough. A lemon eaten
before breakfast every day for a week
or two will entirely prevent that feeling
OF lassitude peculiar to the approach of
spring. Perhaps it's most valuable
property is its absolute power of de-
tecting any of the injurious and even
dangerous ingredients entering into the
composition of SO very many of the
cosmetics and face-powders in the mar
ket. Every lady should subject her
toilet-powder. to this test. Place
teaspoonful Of the suspected powder in
. glass, and add the juice of a lemon.
If effervescence takes place it is an in
fallible proof that the powder is dan
gerous and its use should be avoided,
as it will ultimately injure the skin and
destroy tho beauty of the complexion.
How're RENDER WOOD INooMBusr1B1E.
The following compound is claimed
to render wood incombustible without
affecting its natural color: Sulphate
Of zinc, 81 pounds; American potash,
% pounds; American alum, A pounds !;
oxide ofmanganese, 22pounds :sulphuric
acid of 60 degrees strength, % pounds,
and water, IS pounds. The solids are
first placed in an iron vessel containing
the water at temperature of IS degrees
centigrade, and, when they are dis
solved, the sulphuric acid is added, in
small quantities at time, until the
whole is saturated. The wood is then
laid, with half an inch space between
each piece, on iron gratings on suita-
BILE apparatus, into which the mixture
is pumped until all the spaces are filed.
Heat is applied and the wood is boiled
in the mixture for about three hours,
when it is taken out and dried for use
in the open air. After this treatment,
it is said, wood resists very intense
heat, it's surface only being charred
slowly, while its fiber remains intact.
FRE-PRooB CoMPos1r1oNs.-Vari
combinations of ammonia and borax
have been suggested in Paris for
rendering textile fabrics uninfamma-
BILE. Here is one. applicable to ali
kinds of goods: Sulphate of ammonia
pure), 8 6los; carbonate of ammonia,
2.5 kilos; boracic acid, 8 kilos; borax
(pure), IL kiles; starch, 9 kilos; water,
100 kilos. It is simply necessary 10
steep the fabrics in hot solution COM
posed as above, until they have become
thoroughly impregnated, after which
they are drained and dried sufficiently
to enable them to he ironed or pressed
like starched goods. A second COM
position to be used for theatrical seem
cry (or the mounted but implanted can.
vas to be used for this purpose), and
also for woodwork. furniture, door and
window frames, etc., is to be applied hot
with q brush like ordinary paint.
It is composed of boracic acid, S kilos !;
hydrochlorate of ammonia OF sal am
moniac, Is kilos; potassic feldspar,
5 kilos; gelatine, Is kilos; size, so
kilos; water. 100 kilos; to which is added
a sufficient quantity of a suitable calca-
reous substance to give the composition
| sufficient body or consistency. Another
composition, applicable to all kinds OF
paper, whether printed or not, including
| securities, books etc., is formed of sui
plate of ammonia (pure), 8 kilos; Boz
racic acid, 3 kilos; borax, IL kilos; Wa
ter 100 kilos. The solution is heated
to 1872 degrees Fahrenheit. If the pa
per be in sheets or printed, it is simply
immersed in the solution, spread out to
dry, and afterward pressed to restore
the glaze destroyed by the moisture.
The above compositions insure high
degree Of incombustibility. The pro.
portions of the several ingredients are
! given as examples only, and may be va
! ried as found necessary in practice.
