According to Prof. Harrison Cana
dian hailstorms have two unknown
species Of Heterogeneous to which
he has applied the names, respectively,
of Bacterium havus grandinis and Mu-
cor malleus grandinis He also like
preceding investigators, has discover
ed in hailstones various huOrescing
bacteria, which leads him to support
the theory of Bujwid that hailstones
are produced from surface water
which is carried up by storms and then
frozen.
DR.. f. A. Cook, describing the effects
Of the long Antarctic night on the hui
man body and mind. says that on the
exploring ship Belgica, as the cold
night heightened. all became pale
with a kind Of greenish hue" The
heart grew feeble in its action. The
men were incapable Of concentrated
attention, or of prolonged thought One
sailor was driven to the verge of in
sanity, but when the returning sun be-
gan to appear above the horizon he
recovered.
Sir John Murray in a recent address
drew a vivid picture of the time, in
the remote future, when temperatures
as low as those which Prof. Dewar
produces in his experiments at the
Royal Institution will prevail all over
the earth. The atmosphere and the
oceans will then have disappeared
within the rocky crust of the globe,
their elements having entered into new
combinations. In other words, to use
Sir John Murray's expression, the wa
ters of the ocean will have become solid
rock But over their surface will roll
the waves of new and most wonder
full sea, AN ocean of liquid air about
forty feet in depth" AT that time, of
course life as we know it will have
vanished from the earth.
Human science owes many a debt
especially on the practical side, to the
instinct of the lower animals. One OF
these obligations is intimated in a re
cent scientific review Of the subject OF
dams. Engineers frequently builC
dams straight across streams, the OBJ
ject being, in some cases, to save ex
pense by sparing material. But the
beaver arches his dam against the cur
rent, and experience mas shown tina
this form of dam is best to resist floods
and the impact of floating ice. Acting
upon the knowledge which is instinct
i've with the beaver, and which human
calculation approves. the great Bea
d, Valley dam in California and som'
= other recently constructed dams hav'
, been so made that their stability large
' ~ depends upon the resistance whicl
their arched form presents.
