"A paint, which is rendered self
luminous by mixing with it sulphide
of lime or some such phosphorescent
substance, is attracting public notice in

The earthquake of Lisbon in 1855
was felt over surface of Is, 566,0
square miles, or over twelfth part of
the earth's surface. Such extensive
shocks are generally attributed TO vol
canic action. Observers at the center
of the area perceive a vertical oscilla-
ton; the movements become more
oblique on going from the center, the
waves being propagated with regu-
larity which is not observable in the
ordinary earthquakes of non-valcanic
countries.
"A correspondent tells the Eveniaag
Post how to climb stairs without fatigue.
Always 60 up, he says, while inspiring
or drawing in the air, never while re-
spring. At the first stop begin to in
spire, at the fourth or fifth step stop
long enough to respire and to begin in
spring before starting again. BY this
means the fatigue is greatly lessened-
indeed, reduced to minimum. Elder
ly or delicate persons should never
hurry up stairs. By taking it leisurely
and in the manner described, they will
save both breath and strength.
DIR. j. Fl. Provost has found that
rain removes much more matter from
an uncropped than from a cropped soil.
He placed three inches of soil in two
glazed earthenware pans seventeen
inches in diameter. Four grammes of
white clover seed were sown in one of
the pans, and the other was left with
out any stimulus to vegetation. Both
pans were exposed from July 21st to
October 4th, and then the drainage
water was collected and analysed with
results which warranted the above con-
clusion.
