BITS OF SCIENCE.

To make good black Varnish for iron
or Other metals, dissolve by heat three
ounces of asphaltum, four quarts of boiled
oil and eight ounces of burnt lumber. Mix
the compound with turpentine while cool
ing.
DR.. Settler, in the Boston Medical ard
Surgical journal, recommends beef tea,
made very hot with red pepper, for de-
Iirium tremens. A London surgeon is
stated to have treated. $50 cases success
fully with this remedy alone.
One of the best methods, says NJ. ?. de
Gasparin, of preventing the ravages of
the phyllOXera is 30 keep the soil Of the
vineyard continually moist, and ia the
southeast of France this is effected by
keeping the vineyard submerged during
the winter.
Prof. Fisher, Qf Munich, has succeeded
in obtaining from distilled coal a white
crystalline substance, which, as far as
regards it's action ON the system, is eX-
actly the same as quinine, though it as
Stimulates with the stomach more easily
than quinine does.
10 nickel zinc has been hitherto a some
what difficult operation. NJ. Meidinger,
Of Carlsruhe, amalgamates the zinc first
in ISOLATION of chloride or nitrate of mer-
curry, calculated with sulphurie or muri-
attic acid. By this means a feeble current
of electricity will answer the purpose.
NJ. Gayon has obtained illuminating gas
from stable yard manure kept in close re-
ceDtacles. One cubic metre of fresh horse
drOppings Welded about 1853 cubic feet of
/ carbureted hydrogen in twenty-four hours.
/ M. Pasteur thinks that after supplying a
useful lighting and heating gas the ma
nure remaining, not having been deprived
of ammonia by the process, might still be
serYiceable as q fertilizer.
1t has been discovered by experiments
with dogs placed under the influence OF
morphia even to coma, that the hypoder-
mic injection of solution of theme, the
active principle Of tea, is an almost in
Simultaneous antidote, neutralizing the
| effect of the narcotic and reViving the
| animal, after the action of the heart has
become imperceptible. Caffeine possesses
similar properties, but is less immediate
in its operation.
What the Colonies and India call a kind
| of natural cement has been found on the
bank Of the Bow river, few mics west
/ of Calgary, in the Canadian Northwest
| 1t is the same kind of material as that
| which was found near Morley last au-
I tumn, and which is also plentiful in Flor
| ida, where it is said to be superior to stone
! for building purposes. 1t has been used
| almost entirely in building the town and
fort of st. Augustine in that State, where
it is called coquina.
To make sticky fly paper, take of resin,
in clean pieces, four ounces, castor oil
two ounces. Melt together by means of a
water bath and spread on any sized paper.
If it should be an advantage to have some
thing sweet, it is probable that glucose,
thickened by au addition of deXtrin or
gum. would be very attractive to the flies.
But, as this mixture would be liable to
soak through paper in very hot weather,
it would probably be safest to spread it
on Parafined paper.
The dendOHzatlon of the water of the
Thames at Barking Reach, where two
great outfalls of London sewage meet the
river, was accomplished by the use Of 140
tons of chloride of lime daily. The con-
dition of the stream at this point has been
so greatly improved that a much smaller
quantity of the disinfectant has become
necessary. But from Lea Bridge Road to
TOttenham the Thames is described as
being simply common sewer, the stencil
from which is intolerable.
A German contemporary says the intro
duction of steam in inclosed spaces for the
purpose of extinguishing fires has been
successfully tested in Berlin. The owner
of a steel-pen factory in that city, in con-
sequence of frequent outbreaks of fire in
the drying rooms, had steam pipes placed
in three of the rooms, shut of by short,
soldered pipes of an easily flowing alloy
of lead and tin, arranged to work auto
maticallv. One dav kissing noise made
the fireman aware that one of these APP
planes was brought INTO action, and it
was found on examination that the con-
tents of the drying room had become lg-
nited. but that the steam set free had eX-
tfuguished the fire before il could spread.
