Silk worms, in Flammarion's expert
mentS, have attained their maximum
production in white, red and blue light.
The first two planetoids in 1900 were
discovered, the one by the Austrian as
tronomer Pa!iga and the other by
Charlois of Nice.
Measurements by an American mi
croscopist to test the theory that the
red blood corpuscles vary in size in diff
ferent races have failed to show any
marked differences.
New mines of Ignite have been dis
covered in Germany which are of con
siderable Importance; they are located
at Quadrat, in the neighborhood of
Cologne. a series of soundings has
shown the presence of compact mass
OF Ignite from forty TO fifty feet be-
low the soil; the bed extends over sew
eral hundred acres. The extraction
has commenced and at the present
time about 600 tons of briquettess are
made per day, these being used to re-
place coal.
The inst section OF the great Russian
pipe line has been completed. The
pipe runs parallel to the Trans Cau-
casian Russian State railway. The
section 1usI completed is 145 miles long.
The pipe is of wrought iron, lap-welded,
and the internal diameter is eight
inches. 1t was made in Russia from
native materials. There are three
pumping stations with two pumps in
ceach, only one being used regularly,
the other being kept as a reserve. 1t
is expected that 416,275,2 200 gallons of
oil will be, pumped per annum.
The growing of Belgian hares for the
market in Southern California is de-
scribed by Mr.. o. p. Wolcott, in the
Scientific American, as having recently
become an extensive industry. The
hares are imported for breeding pur-
poses from England and Belgium. A
high-bred buck or doe hare, Mr.. VOL
colt says, will bring from $50 to $3.50.
In the mari cts the price is about %
cents per pound, live weight. From
Los Angeles shipments are now made
to all parts of the United States. A
warm climate is not essential for the
animals, and it is said they could De
grown for the market in almost all
parts of the Union.
A Russian inventor, X. Danilewsky,
has recently experimental, under gov
ernment auspices, with fying-ma-
oh 81, "A,
power of Il balloon with something re-
sembling wing action. The balloon is
shaped like IL projectile, and is small,
being filed with pure hydrogen. Its
ascensional force is sufficient to neu-
tralize the weight of the aeronaut and
the apparatus The latter consists of a
system of movable aeroplanes and a
steering tackle, by means of which the
aerOnaut guides the course of the bal
loon. In descending, the latter assumes
an upright position. The immediate OBJ
ject of the experiments is to provide a
dirigible balloon for the signal-corps of
the Russian army.
Visitors to museums of science are
always interested in the mounted skele-
tons of gigantic extinct animals, but
they seldom appreciate the amount of
study and skill required to properly
match the fossil bones together. Even
at the best it seems probable that many
mistakes are made, and extinct mon
sters may sometimes be caused to as
sumo forms and attitudes unknown to
them in life. This is indicated, not
only by the differences between the
restorations made by various natural
lists, but by recent remark of Prof III.
9. Osborn, an expert in the mounting
of fossil skeletons, that If we had had
nothing but the skeleton of the ee-
phant to work upon, we should proba-
bly, have obtained very faulty con
eeption of the animal.
