An excellent sedatiye water for exter-
nal application for bruises or aches of any
kind, is composed Of ammonia > ounces,
tincture of camphor y drachms, common
salt > ounces, and water two pints. Mix
and dissolve it without heat. This is
largely used in France, and is sold in this
country under a patent medicine name.
1t is an excellent lniment for cattle when
strengthened by the addition Of 10 drs.

Degrees Of temperature are often men,
toned rs so many of Fahrenheit, which
is the thermometer used in this country
and in England. On it the boiling point
of water is marked PIP and the freezing
point 81. There are two other scales
used by thermometer makers, called the
Reaumer and Centigradc. Water boils
at 80 degrees, Reaumer. and at 100 Cen,
tigrade, while both mark the freezing
point 0, or zero. Centigrade, giving 100
degrees between the freezing and boiling
points, is the simplest and most scientific,
while Reaumer and Fahrenheit are arbi-
trary measures. All these scales being in
use, it is sometimes a little perpleIing to
know what temperature is meant. \
ready means Of converting the degrees OF
the different scales may be found in the
following formula: 1 Reaumer equals >
Centigrade and 9 Fahrenheit, thus AR.
sc. aud OF. are equal. Or, | Reaumer
equals u Fahrenheit, while Centigrade
equals $40 of same, thus $50, the
number OF degrees between the freezing
ard boiling points of Fahrenheit; 2l2-
32=lSO. The comparison is clearly set
out below.

For mending valuable glass objects
which would be dis6gured by common
cement, chrome cement may be used -
this is a mixture Of 5 parts gelatin to !
of a solution Of acid chromate of lime.
The broken edges are covered with this,
pressed together and exposed TO the sun
light, the effect of the latter being to rem
der the compound insoluble even in boiling
water.
1t is said that eggs may be preserved
for six months by dipping them in linseed
oil, and so placing them iii layer of sand
that they do not tou,h.
Grease can be removed from billiard
or other cloths by paste OF fuller's earth
and turpentine. This should be rubbed
upon the fabric until the turpentine has
evaporated and white powder remains.
The latter can be brushed of, and the
grease will have disappeared.
Chloride of calcium is such deliqui-
escent salt that it attracts enough moist
ure to prevent glue from cracking. Glue
thus prepared will adhere to glass, metal,
&C., and can be used for putting on labels
without danger of their dropping of.
A precaution which is often overlooked
is the preventing of the spring plates of
carriages rusting where they are joined
together and not covered with paint. The
Joints should be fabricated and the best
ma terial for this purpose where dark COL
ors are used in painting, is compounded
OF two parts each of pure beef and NUT
ton tallow to one part of black lead well
mixed, applied warm and in small guam
titles. When light coloIs are used in
painting, diminish the quantity of black
lead.
A farmer correspondent sends US an
excellent wrinkle for finding the weight of
horses or steers without scales. He says
"Make a weighing stall about three feet
wide, with level floor. In the latter
make a recess for the platform of the
scales. so that the platform will be flush
with the planking. Now lead your horse
or steer into the stall so that the fore feet
of the animal rest on the platform, and
note the weight, then start him ahead I'M
til his hind feet are on the platform, note
the weight again. Add the two weights
thus taken, and the sum will be the total
weight Of the animal"
