lava flowed in great waves over the circumjacent lands. This seemed to
indicate a lengthy eruption; but, to the surprise of those interested
in volcanic phenomena, on the third day the eruptive movement began to
decrease, and, during the night, stopped entirely. This was a very
fortunate circumstance, for this eruption would have caused immense
damages. It cannot be disguised, however, that the eruptive attendants
of this conflagration remain under conditions such as to constitute a
permanent danger for the neighboring villages. It has happened, in
fact, that in consequence of the quick cessation of the eruption,
those secondary phenomena through which nature usually provides a
solid closing of the parasitic craters have not occurred. So it is
probable that when a new eruption takes place it will be at the same
point at which manifested itself the one that has just abated.--_La

PHYSICS WITHOUT APPARATUS.


Take an ordinary wine bottle and place it in front of and within a few
inches of a lighted candle. Blow against the bottle with your mouth at
about four or six inches distant from it and in a line with the flame.
Very curiously, notwithstanding the presence of the bottle and its
interception of the current of air, the candle will be immediately
extinguished as if there were no obstacle in the way. This phenomenon
is readily understood when we reflect that the bottle receives the
