The moor has twenty-eight noun
tains, higher than Mount Blanc.
The feat of seeing the satellites of
Mars with a telescope is said to be
equivalent to that Of a person at New
York seeing an object only two inches
in diameter at Boston.
M. Chappins suggests that the pres
ence of ozone in the upper regions of the
air may give to the sky its blue tint.
He argues that ozone is being constantly
produced by electrical discharges, and
recent researches have shown that ozone
is blue in color.
Mr.. Alex. Adams has made the re-
markable discovery of electric tides in
telegraph circuits. By long-continued
and careful observations he has deter
mined distinct variations Of strength
in the earth currents, which are always
present on all telegraph wires, follow
ing the different diurnal positions
Of the moon with respect to the earth.
Interesting new discoveries have been
made at Pompeii. In n district a
house has been ~excavated which was in
the course Of construction when the
terrible catastrophe befell the city, and
which differ from all other Pompeian

large square piece Of black glass was
found fixed into the wall, which, when
moistened forms the most perfect mir
ror. In a third house various wall
paintings were discovered possessing an
artistic rather than a scientific inter-
est.
DIR. Delaunay, a well known Paris
sarant, claims the discovery Of a curious
neal of guaging a persons intelli-
gence. To ascertain the qualities of an
applicant cook, for instance, it is sufi-
Client to give her a plate to clean, or
sauce to make, and watch how she
v her hand in either act. If the
motion is from left to right, or in the
direction of the hands of a watch, she
may BIO trusted; If the other way she
is sure to be stupid and incapable. The
intellectually Of other people may, in
like manner, be determined by request
ing them to draw a circle on paper, and
noting in which direction the hand IS
moved. The inferiority of the weak
minded is invariably indicated by their
drawing from right to left.
That germs of disease may live for a
long period seems to be proven by re-
cent experiments under the direction of
M. Pasteur, seven sheep were led, daily
for a few hours, to a piece of ground
where some animals that died of an
thracoid disease. or Charlton, had been
buried t,celce gears previously. Two Of
them caught the disease and died.
There was no grass for the sheep to eat
and it is thought those two must have
received the germs in the course of
smelling about the ground. On part Of
the ground covering the remains of the
diseased animals, vegetables are now
grown; and NJ. Pasteur sought to learn
if any person about the farm had been
affected. The farmer knew of none.
but showed a healed sort of malignant
pustule 1.-THE same kind of disease) on his
own face. NJ. Pasteur supposes that if
the vegetables eaten had not been
cooked, there might have been a differ
emit tale to tell.
In 1869, Herr Won Behold inferred,
from observations in Bavaria, that
there was an increase from year to
year in the numbers of buildings struck
by lightning. There seemed to be also
au increase In the number of thunder
storms. Herr Holtz has lately made a
fuller inquiry on the basis of data from
all psrts of Germany, and from Austria
and Switzerland. He publishes two
tables, mi to show the increase or de-
crease of thunderstorms, since 1854,
since 1852 and since 1870, in the differ
emit regions: the other, the increase or
decrease of lightning risk estimated
from comparison of the number of
lightning struck houses with the entire
number Of houses. 1t appears then
that while any increase in the number
Of thunderstorms is extremely small and
there is In some cases ever a decrease,
the lightning risk shows a very large
increase. and in nc case a decrease.
Thus, the increase of risk from light
ming must be regarded as not dire,
unless in very slight measure to meteor
