A MAGNIFICENT new swing bridge
across Leith harbor has j1st been
opened. The bridge, which is OF iron,
cost f32, 900, and weighs $50 tons. 1t
contains two lines for railway traffic,
and two roadways for foot passengers.
No FEWER than 10000 persons are,
in Glasgow and its neighborhood, at
tendants at some musical class or other.
and for years past half the certificates
and prizes given by the Society of
Arts have fallen to competitors of this
district.
A PECULIAR result has been arrived
at by Professor Flick, of Wurtsburg, in
his experiments on the blood-pressure
in the aorta of the dog He finds that
if straight tube in the manometer
employed, the column of fluid rises
higher when lower end is in the aorta
than when in the left ventricle.
1T concerns those who trip the light
fantastic toe to know that one young
lady in this city lately received such
injuries by falling on a waxed ball
room floor as resulted in death while
another, at ball, Friday night, struck
the staging of the platform with such
force as to drive bairpin into her
skull, producing a serious and very
painful wound. -CongregationoLiSt.
ABSOLUTELY pure iron is said TO have
been prepared by Russian chemist
by means OF the galyanic battery.
During the process large quantity of
hydrogen was disengaged from the
ordinary iron used. The pure iron is

and ductile, and so soft as to be readily

especially in organic liquids: In
the presence OF cold or lukewarm water
beuzoic chloride is only decomposed
with extreme siowness, but, on adding
alcohol to the LIQUID, benzoic ether is
Immediately formed and is thrown
down ID excess. The presence of this
ether becomes apparent If a few drops
of the liquor are heated with a solu-
tien of caustic potash; the chloride
only is decomposed, while the ether
remains unaffected. This reaction is
vely evident with a liquid containing
one per cent. of alcohol, and allow us
to dispense with distillation.
In some recent experiments on the
effect of alcohol ON the blood, made by
Professor Binz, of Bonn, it was found
that moderate doses caused distinct
decrease IN the temperature of the
blood, extending over half an hour or
more and inebriating quantities
caused a still more decided lowering,
as much as from three to FIVE degrees
f., which lasts Tor several hours.
Professor Binz also found that when
putrefying blood had been injected
under the skin of an animal, the adj
dition OF sufficient quantity OF diluted
alcohol in nearly every case preserved
the life of tho animal; those receiving
no alcohol dying in two or three days.
A VALUABLE antiquarian discovery
hes been made near BournemOuth, on
the farm of Mr.. Robert Hare. He
states that eighty.six urns, many of
them containing portions of human
bones, have been dug up. A portion
OF the mound where they were found
| has not yet been removed. The urns
are, in Mr.. Cox's opinion. Roman, but
few persons who have already visited
thn spot think they must be ancient
British. Only one of the urns has
been secured in even tolerable preser-
walton. They are found only six inches
or eight inches below the surface, and
about two feet deep. They quickly
crumble to pieces on being removed,
but il exposed to the air for time they
become hardened.
| In the Revue Scientifque for Decen-
Der il is stated that a third skeleton
Of troglodyte has been discovered by
| NJ. Rvlere in the caves of Mentone.
This new skeleton, judging from the
various and numerous implements by
which il was surrounded, lived at an
epoch far more remote than that as
signed TO the skeleton now in the mu-
scum of Paris. The instruments of
warfare and other objects found with

are not polished. They are only
sharpened, and by their coarse execu'
ton appear TO belong to the pal@o.

skeleton was a large number OF shells,
each pierced with a hole, which APP
