The tint of birds eggs, especially the
light colors, are apt to fade, on expos
ure in museums TO too great sunlight.
This Is the case with the greenish blue
eggs, as those of the murre. BY ex-
pertinent the darker colored eggs oil
olive brown or chocolate hue have been
found TO undergo little change.
A very curious method of making an
underground conduit or pipe Is reported
from France A trench is dug, and ee-
ment or concrete placed in the bottom.
On this an inflated eanyas-eoyered
rubber tube is laid, and more cement
Is added until the tube Is covered
When the cement has set, the tube Is
allowed to collapse and Is withdfawh'
leaving a concrete or cement CONDUIT
A Russian chemist has discovered a
most powerful anaesthetic. 1t Is sever
al thousand times more powerful tnah
chloroform, volatiizes most readily,
and acts when freely mixed with air nj
great distances. Experiments are being
made at st. Petersburg TO see II 1t can
not be enclosed in bombs, which would
have the extraordinary effect of an
aesthetlzing instead of woundlng the
enemy.
A correspondent of Nature tells re-
markable story of dog, which haY-
ing, through an accident, lost both legs
on the right-hand side, has learned 10
walk and to run on its two remaining
legs. Enough remains of the right
foreleg TO serve as an occasional prop,
but when running the dog touches the
ground only with the two left legs.
With these 1t hops rapidly along, and
having been a trained sheep-dog before
the accident it manages TO herd Its
flock as 1t did when it had all its legs.
The Scientific American describes an
electric trolley road wagon which has
been invented and tested at Reno, Ne
vada. Wires, like those used in city
streets, are stretched on poles along the
road, and the wagon receives its cur
rent from those wires by means OF
connecting cable, automatically, 10 two
hundred feet, IL necessary, thus permit
ting the wagon TO turn around, or 10
follow curves In the road. 1t Is sug-
gested that water-power may be ntil-
lied to develop the electricity.
The use of aluminium Is gradually
spreading, and has now been applied
to the making of ylollns. NiOllns made
entirely of aluminium are said 10 have

and the inventor declares that he has
found a property in the metal which
consists of tendency of the funda-
mental tones TO outweigh the upper
tones. For this reason means are EN-
ployed by which the player can regu-
late or introduce the partial tones to
suit his individual taste. Naturally the
feeling for wooden violins Is still very
strong, but the aluminium instruments
are having a steady sale.
How often we hear the remark. I'VE
shall have rap. the atmosphere is so
heavy" The reverse is true. When one
sees smoke hanging from chimney,
with a tendency TO sink to the ground,
II indicates that the atmosphere Is
light-in fact, too light to float the
smoke. When the smoke rises from
the chimney 1t indicates a heavy at
mosphere. \ column of smoke is not a
bad barometer, for barometer simply
records the pressure of the atmosphere
When the atmosphere Is light and the
smoke settles, the pressure of the mer-
curry is light and the column falls, in
dicating storm. When the atmosphere
is heavy and the smoke rises, the pres
sure Is greater and the column rises, in
dlcating fair weather.
