SCIENCE AND INDUSTRY.

There are a54 registered trade unions
In England and Wales, with a member
ship Of about $780, 900.
"A locomotive engine has boon per
fected in England, and was recently
tried on one of the roads, which can
make, average time, nincty miles an |
hour.
The effect of the electric light cur
rent on the compasses of some vessels |
is so great that it becomes necessary to
determine how many hours the dynamo
has been running before working out
the vessels reckoning.
Paper is made in France from hop
vines; and it is claimed that the fibre
secured is the best substitute for rags
yet obtained, as it possesses great
length, strength. fiexibility and delicacy.
LIN cases where there has been exces-
sive vibration noticed with engines
bolted to beams or Orders of the upper
stories of buildings hanging heavy
weights from the bottom Of the engines
has overcome the vibration almost en-
tirely.
Aluminium bronze is coming into ex-
tensive use in Germany for propeliers
and other fittings for boats. The alloy
consists of 90 per cent. of copper and 10
per cent. of aluminium, looks like gold,
and has the same weight as IRON
Great progress is being made In
rapid photography. Lord Rayleigh has
photographed a minute jet of water in
the 100, OOOth of second; and new
camera takes ten successive views sec
ond on the turning of crank.
"A new disinfectant has made Its ap-
pearance under the name of thiocamph.
1t is a combination of camphor with
sulphurous acid, containing over sixty
times its volume of sulphurous acid gas,
which, upon its exposure in q warm
room, is gradually evolved.
Experiments have recently been
made in Spain on the action of sunlight
in maturing wines. Layers OF new
wine in bottles of colored glass have
been exposed to the direct rays of the
sun, with the result that both flavor and
quality have been improved. In the
south of Europe there has been prac-
tice of ripening cognac by exposing the
bottles on the roof for years.
"A regular industry is being started
in this country in the manufacture OF
gearing for electric railways out of raw
hide. 1t is preferred to metal, as 1t
makes far less noise and wears better.
The material is said to finish up in the
working as we'll as metal. The use Of
this material indicates that very severe
strains are brought to bear upon cogs
not capable. If of metal, of standing the
stress.
/ The electric microscope promises tc
make some wonderful revelations in the
world of science At a recent medical
a congress in Europe microscopical prepar
. atoms under magnifying power OF IL,
z 600 linear were made visible to an as
o semblage of 800 persons. The pulsatinl
Q heart of a dog and the heart beats pro
duced by suffocation were successful,

y Experiments recorded by the medi
cal press indicate that most microbe
d succumb soon after their victims hav'
y died. Tests were made with nine differ
emit micro-organisms and the bodies o
it the animals killed were eithor burie'
n or kept under water or exposed to tn
it air. The bacillus of fowl cholera wa
l. seldom found after three weeks, bu
the tubercular microbe did not los
v its virulence until 2O4 and 252 days ha
Ie elapsed. All trace of the other organ
isms was lost in from three days to
s, week, including those of typhoid fever
