"A Spanish physician, DR.. Olive,
makes use of powdered oobwebs as .
remedy for fevers.
Paper made from strong fibres can
now be compressed into substance so
hard that nothing but the diamond can
scratch it.
1t has been affirmed that It is posi-
BILE to transmit electric energy for work.
ing motors to short distance only. NJ
Deprez now shows, however, that con-
siderable percentage of the original pow
er may be made available at distance
as great as fifty miles.
The largest trees known are probably
Eucalyptus SmygdaliHa, OF pepper
mint tree, growing in the Dandernong
district of Victoria, Australia, which is
said to measure $40 feet to the starting
point of the crown, and AIT feet to the
top. and another specimen Of the same
species, mentioned by Baron Ferdinand
Won Muller as having attained the height
of 480 feet.
1t has been proven by direct COM
parison that objects which are white by
sunlight appear yellowish under the cleo
trio light, and red when seen by gaslight.
The Illusion" says DR.. Werner Sie-
mems, "arises from our being accustomed
to see the earth redly illuminated after
sunset, and on this basis forming a diff
ferent scale of colors for ourselves. Day
light would accordingly by night appear
still bluer than the electric light. This
false idea would disappear if electric il
Elimination become general"
Prof. Boyd DAwkins, in depicting
the appearance of the world before man !,
recently described America in the eoeene
and miocene periods as being connected
with Europe by heavily wooded barrier
of land stretching past the Farce Islands;
while the slligators and fishes of Europe
were indiytinguishable from those Of this
continent.
An interesting experiment is said to
have been made with alternating hedge
hog, in which the brain of the sleeping
animal was removed, then the entire
spinal cord, but for two hours hardly
any change was noticeable in the action
of the heart; and day sfterward that
organ contracted when touched by the
operator @
During an address by Prof W. e.
Ayrton on the storage of power" the
lecture theatre was lighted, q circular
s.w driven and an elevator operated by
means of electric energy which had been
stored the previous day in Faure accum-
ulating batteries. The total quantity of
energy was $4,000, 600 foot-pounds-a
little more than twenty-five horsepower
exerted for one hour. A single cell, con-
tanning 81 pounds of lead and red-lead,
is found to store !, 400, 900 foot pounds of
energy.
Seasons of low water in the lakes of
Switzerland offer favorable opportunities
for adding to our knowledge of the an
cient lake-dwellers. The waters of Lake
Constance has lately been lower than at
any other time since 1906, and advantage
has been taken of it to examine num-
be- of lacustrine dwellings, with the re-
suit of numerous discoveries Of imple-
ments.
In q recent lecture, Prof. Edward
Frankland stated that six millions of tons
of coal are probably burned in London
during the winter months, and the guam
titles Of steam, SCOT, tar and sulphurous
acid discharged into the air as products
Of this combustion are enormous. These
products unite to form the London fogs.
Steam supplies the basis of oil fog. and
the vapor particles become covered with
tar, which renders them more permanent;
dirt is necessary TO produce fog, while
sulphurous acid promotes it. DIR. Frank
land illustrated these points by expert
ment To prove ths effect OF dirt in the
air he filed large flask with moist air
freed from dirt by Offering, then cooled
the flask, when slight mist was formed
which disappeared in moment; repeat
ing the experiment with air containing
its normal charge of dirt, the fog was
much more dense and lasting. larry
matters render fogs persistent by retard-
ing evaporation. He believes that the
general substitution of anthracite for BIZ
luminous coal would do much toward
freeing the metropolis from its fogs, as
tho discharge of tar and SCOT into the at
mosphere would be vastly lessened.
