Popular Science Notes.
Since the extensive manufacture of
oleomargarine, an artificial butter,
there have naturally arisen many
questions as to its wholesomeness
hence we deem few words from us
regarding this new production, its
properties and manufacture in order.
The opinion Of most chemists of emf
hence who have given the subject
their attention, is that it is as whole
some an article of diet as natural but
ter. 1t is made OF the fresh fat of
animals, which having been rendered
in such manner as to make it quite
pure, odorless and tasteless, is
churned with milk, etc., by which
process it is converted to the consis.
tency and appearance of ordinary
butt.r. When ready for market, the
chemical composition Of the product
is essentially the same as that made
from cream, and IN most instances
could not be detected from the genu-
inc. No one need be afraid of oleo-
margarine.
A green coloring matter suitable
tor wall paper, and other similar
uses which is unlike other greens in
containing no poisonous substances,
has been produced by calcining an
intimate mixture of one part OF BIZ.
chromate of potassa and three parts
of baked gypsum. A grass.green
mixture is obtained, which, on boil.
ing with water, or on mixing with
dilute hydrochloric acid, leaves a fine
powder of an intense green color.
The poisonous effects of arsenical
greens is well known to the public,
hence the above new discovery will
doubtless meet with great favor if as
good as claimed, lit is not only
quite cheap, but is free from obiec-
tons on account of its freedom from
danger.
Black, white, red and yellow col
ored inks have recently been put on
the market by house in Leipsic,
which are expressly designed and
used for writing labels on glass,
porcelain, ivory, marble, mother.of.
pearl and metal. The writing is ap.
piled with goose-quill, and when
dry is said to adhere SO firmly that it
cannot be removed by any liquid or
chemical process whatever.
The making of cog or tooth. wheels
of leather, prepared from Unframed
bufalo-hides, thoroughly cleansed
from hair, etc. in place of metal, has
been patented, and mandatory al
ready established in New York. The
advantages claimed for them are
that they have a much quieter and
more elastic run, are extremely dura.
BILE, and require no fabrication what
ever.
Those who have experimental in
the matter state that door standing
loosely on its hinges, that would
readily yield to gentle push. would
not be moved by cannon-balI pass
ing through it. Owing to its rapid
passage, the ball in passing through
overcomes the whole force Of cohesion
among the atoms of wood, and the
inertia of the door is not affected to
an extent to produce motion.
An application has been made to
the English Parliament by tie North
British Railway Company, for the
necessary powers to reconstruct the
i'll. starred Tay Bridge. The cost Of
rebuilding the structure is estimated
at about sS25,ooo.
The New Orleans Water. works
Company are having constructed a
compound engine, having a daily ca
pacity for pumping 100000 gallons
of water, being more than any other
one now in use.
All metals are capable OF assuming
under favorable circumstances, the
crystalline form. Many of them, par
ticularly gold, silver, copper and bis.
muth, occur crystallized in nature,
and are found either as cubes or oc
tahedrons, or in some of the deriva.
tive forms; anthony is, however, an
exception t this rule, and affords
rhomboidal crystals. In order to
crystalline a metal artifcially, it is
so letimes sufficient to melt a few
ounces in crucible, and having per-
mitted it to cool on the surface, to
pierce the crust formed, and allow
the interior to flow out. By this
means. very eautiful crystals of bis
muth may be obtained.
Leverrier, the chief astronomer of
France, confident in the real exis-
tence of the planet Vulcan, has lately
calculated the orbit of that mysteri.
Gus planet from the various recorded
instances of dark spots seen for a
few hours only upon the face of the
sun, and he now announces that the
planet may be looked for at about
this time, to the east of the sun, and
about twenty sun breadths from that
orb.

1t is proposed to construct a mon.
ster floating railway station, capable
of carrying trains across the English
Channel at the rate of IA knots an
hour. According to the scheme,
each train would provide aecommo.
dations for 1000 passengers, and
would require four more coaches.
