. 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 of
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 ce-
ment or concrete placed in the bottom.
On this an inflated canvas-covered
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 withdrawing
leaving concrete or cement conduit.
A Russian chemist has discovered
most powerful anaesthetic. 1t is sever
al thousand times more powerful than
chloroform, volatilizes most readily,
and acts when freely mixed with air at
great distances. Experiments are being
made at st. Petersburg to see if it can
not be enclosed in bombs, which would
have the extraordinary effect Of an
aesthetizing instead of wounding the
enemy. ...-
A correspondent of Nature tells a re-
markable' story of a dog, which hav-
ing, through an accident, lost both legs
on the right-hand side, has learned to
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 it hops rapidly along, and
having been trained sheep-dog before
the accident 1t manages to herd its
flock as it did when it had all it's 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 a
connecting cable, automatically, to two
hundred feet, If necessary, thus permit
ting the wagon to turn around, or to
follow curves in. the road. 1t is sug-
gested that water-power may be utll-
lied to develop the electricity.
The use of aluminium is gradually
spreading, and has now been applied
to the making of violins. Violins made
entirely of aluminium are said to have
a richer tone than those made of wood
and the inventor declares that he has
found property in the metal which
consists of a 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 steady sale.
How often we hear the remark, eve
shall have rain, the atmosphere is sc
heavy" The reverse Is true. When one
sees smoke hanging from a chimney
with tendency to sink to the ground
1t indicates that the atmosphere is
| Hght-in fact, too light to float the
smoke. When the smoke rises from
the chimney it indicates heavy at
mosphere. A column of smoke is not 6
bad barometer, for a 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 atmospher,
is heavy and the smoke rises, the pres
sure is greater and the column rises, in
dicating fair weather.
