ship is probably the very finest ircncisd
afloat, being superior in some respects
to tha Nile or Trafalgar Of the British
navy, which. she most nearly rcsem-
bles. 1t is said that her lines are SO
fine, and SO different from those of the
majority Of French battle-slips, that
she looks rather like fast cruiser than
a ship Of the line. The stem, gently
curving outward, fails to recall the
characteristic bOOt-toe form Of the ma
jOrity Of the French ironclads, and the
forecastle is not only high, but actually
deck higher than the atterpart of the
ship. The problem undertaken by the
designer was to combine great speed
with high gun power and as complete
protection as it was possible to give;
and it is claimed that NJ. Lagane has
solved his difficulties in remarkable
manner. Her engine Of 1900 horse
power are expected to give 4 speed Of
seventeen and one-half knots. She car
ries forty four-ton guns on her quarter
andforecastle, and a thirty-four ton gun
on each beam, with a full complement
of quick-firing and other machine guns.
An important feature of her armament
is that her guns are so well balanced
that they can all be trained in any di-
rection without affecting the trim Of the
ship. Another noticeable thing about
the Jaureguiberry is the extensive use
of electricity as motive power 1t
will move the turrets, raise the ammu-
milton, and do much other work which
in the majority of modern ironclads is
done by pneumatic hydraulic power.
1t will also, of course, light the vessel.
The ship will contain $50 incandescent
lights, and there will be six very pow
crful Mangin search-lights.
Electricity in Sugar Refining.
An attempt has been made to utilize
electricity in sugar refining, and al
though the results are attained are not
as specific rs might be wished, there is
ground for believing that the electric
current may soon he advantageously
employed in this branch industry. Won
Lippman describes the process as seen
by him in a beet sugar refinery. The
warm diffusion juice of the beet root
was subjected to 4 given current be-
tween electrodes of sheet zinc. a thick
muddy precipitate separated at one OF
the poles and gradually Sank to the
bottom of the vessel. The electric cur
rent also effected the coagulation Of
the albumen, which carried down many
other substances. Zinc oxide was freely
formed. and constituted fully one-third
Of the weight of the mud thrown down
from the electrode, but the juice was
quite free from zinc. AS, however, the
diffusion juice did not contain much al
bumen, and the zinc plates could be
used for eight days. or longer, it was
impossible to regard the chemical effect
rs very definite or important. 1t was,
therefore, difficult to determine, in the
absence Of analytical data, whether the
excellence in purity of the sugar turned
out at the factory in question was due
to the application Of electricity, or
whether a judicious coagulation Of al
bumen before publication would not
lead to equally good results.
4 Light That Failed.
The electric light has just been sue
oessfully installed in the Royal Ex-
change, London. and in the accounts
Of the formal turning on of the light
by the lord mayor fact is mentioned
that affords curious comment on
English conservatism and the London
climate. 1t is stated that hitherto on
dark or foggy days the operations Of
the exchange have been carried on by
its frequenters only with the greatest
difficulty, and it was not an unusual
scene for several people to be carrying
about lighted candles in order that they
might proceed with their busitess- Such
scenes. which We're more suggestive Of
q medieval masquerade than 4 sober
and determined prosecution Of the COM
mercial pursuits Of the day under ad-
verse conditions, are now Of the past,
and, although a London fog in business
mood will easily discomft and swallow
up any light that ever was on land or
sea, the newly installed arc lamps
can be relied upon to do good service
in both favorable and bad weather.
They will, at all events, save the NOR
chant on Change from the necessity OF
putting a candle into his pocket before
starting for his daily journey to tho
city" when the fog season sets in.
Science Notes.
The railway up the RathhOrn noun
tain in Switzerland probably reaches
higher altitude than any other road in
that country Of lofty lines. Its upper
terminal station is at an altitude OF
7,40O feet, its length is three and 4
half miles and the difference in height
between it's two ends is more than
mile. The road passes over several
bridges and through two tunnels, one
of the latter being about thirteen hun
dred feet long. The gauge is thirty
two inches and between the main rails
is a rack rail into which gear wheels
on the locomotive fit, the train being
driven by the rotation of these gears,
just as the trains up Pixies Peak are
operated. Another road now building
in the same country up the Eger
mountain will reach height of nearly
thirteen thousand feet when complet-
ed.
The position taken by the vegetar-
ians is strongly indorsed, by Mrs. Er-
nest Hart, who says: I'm no country in
the world is home rendered so unhappy
