two important advantages, viz that y q
temperature attniuable is practically linn

that the heat is developed immediatelv in
the substance to be fused instead of tirst

Among the Instruments rsed by Prof.
j. Milne in studying the earthquakes of
Japan is clock which records automat-
ically the velocity of the earthquake
waves. He describes shocks observed nv
him as travelling at the rnte of 10 600
feet per second, decreasing to 4 500 feet
and still getting slower and slower rs they

seconds foi r minutes. Pr + Min is
now at work upon an atlas designed to
show the large number of seismic centres
in which the earthquakes of Japan orig
mate, and the relative intensity of the
waves. with the areas affected.
-relephouing by underground cables
has been pronounced imprscticable for
the reason that such cables must neces-

Der ofconducting wires aud the induction
prevents speech, By means of a spe cinl
of the circuits, Messrs. Fell
ton aud Guilleaume, of Mulhem on The
Rhine, claim to have overcome the effects
OF Induction in these cables. Their sys-
TEN was lately tried on line thirty-two
mil long, and proved so efIectual that
speech was transmitted without trace Of
foreign sound through one wire while
neighboring wire Of the cable was in con.
slant use.
Prof. NJ, w. Harrington refers 10 two
kind of changes on the moons surface
which may be regarded as fairly establish
ed. The first is the landslide. which Is
doubtless caused by the great attentions
of temperature TO which the moon is snb-
iect. Many Of these slides may be easily
with good telesc opes. The
second form Of change is illustrated by
craters which have been proven TO be diff
ferent in size aud shape from what they
were recorded by earlier observers. Many
other chnnges have been suspected, but
they are Of n more uncertain aud doubt
ful character.
