Seloufi6c Notes.

Glass vessels, brass tubes. and other arti-
cles have been coated by Mr.. j. Emerson
REYNOLDS with a nitrous galenoid deposit
through the decomposition OF an alkaline
solution OF lead tartrate with sulphur
nrca.
Regarding the electric conductor, DR.. x.
NJ. Ferguson says that while qualitGtiyeiy
it was founded on scientific principles,
quantitatiyely its construction was guided
by experience, and, TO some extent, even
by guess-work.
When ethyene Is mixed with carbouic
anhydride, nitrogen, aqueous yapor, or air,
il has, Mr.. u. +. FARMLAND finds, lower
illuminating power than when it Is pure.
Ethylene mixed with oxygen has higher
illuminating power than pure ethylene.
Cherry STAN for fine wood Is thus pre-
pared Boil until dissolved four ounces OF
annatta i'm three quarts OF water in copper
kettle; put In piece OF potash OF the size
Of a walnut; keep the whole on the fire
hall an hour longer, and then the stain Is
ready for use.
An electric railroad will soon probably
be finished. uniting the Hotel dies Alpes, at
Territet ChilloD, and the Hotel de Mont
Fleury, which is situated on the steep
mountain-side immediately above Chillon.
1t is intended to use a turbine to drive the
dynamo-electric machines. as the supply
of available water is abundant.
Dried leaves OF the bitter-orange tree are
much used by the inhabitants OF South
America as a household remedy. An in
fusion Of the leaves is regarded in Brazil
as specific for sick headache, flatulence,
indigestion, hysteria, spasms, recent colds,
and chills and fever. Its free use is con-
sidered 10 promote persplration.
A man during lifetime of fifty years,
according to paper recently read before
the Academy OF Sciences, Paris, sleeps
away an aggregate Of 6,000 days, works
away the same period, eats away 1000
DAYS, walks away 800 days, is Ill during
800 days, and amuses himself with the re-
mainder Of his hali-century on earth.
Herr +. Landrin. in paper on the theory
Of mountaineering, calls the silica which
has been precipitated from silicate by an
acid and ignited at a red heat "hydraulic
silica" 1t Is this which effects the harden
ing OF hydraulic mortsrs. He disputes the
hypothesis OF lie Chatelier that the harden.
ing of cement depends, as in the case OF
gypsum, on approximation phenomena.
Paper may be stuck on wood by means
OF this solution: Gum arabic, half ounce !;
powdered gum tragaeanth, half ounce !;
water, one and one-balf ounce; and acetic
acid, twenty drops. 1t will cause labels to
adhere very firmly without staining them,
unless the paper Is OF an unusually bad
quality. A clear solution OF gum arabic
applied once or twice is all the varnish re-
quired in finishing for most purposes.
Anthrax OF man, wherever ii occurs, Is a
very fatal malady. DIR. j. Poland has pre-
pared microscopic specimens OF the pecu-
liar bacillus which produces IL. The spores
OF the disease are no doubt conveyed fire.
Quently In the skins and hides OF animals
which have been tainted with the distem-
per, and persons handling such infected
dry hides become affected with the virus,
the germs developing in the usual manner
Of the low organisms.
Herr Stoupler, Of Lucerne, Switzerland,
added fluorescene to the water Of a steam
boiler. The deep-green color OF the water
was retained by II for weeks. and yet no
trace Of the coloring matter could be de-
tected in the water contained In the steam
cylinder, and he accepted this as proof
that the water which gathers there Is en-
tirely due TO condensation caused by the
expansion OF the steam. and that very little
water Is ever actually carried over enc
chanically" from the boiler by the steam.
