Sir William Thompson lately sng-
gested that hot water might probably be
economically distributed through the
streets Of a city in the copper tubes used
to convey electricity for power, the heat
being produced by the resistance Of the
tube 10 the electric current. Prof. Geo.
r. Barker has made experiments confirm
ing the theory, and expresses the belief
that boiling water may be distributed
for heating purposes wherever the cleo
trio light is in use, without interfering
with the efficiency Of the latter or in
creasing materially the expense.
=" Are the oceans disappearing1" is,
doubtless, q rather surprising. question
to most persons but the question has
been asked and answered Automatically.
The studies Of N. Trantschold Of Moscow
upon the matter leads him to these con-
.clnsions: LIN proportion as certain
parts. of the earth's crust rise from the
bottom Of the sea above its level, the
latter must be lowered. 2. The surface

It rises from the water partly BY reason
OF upheayals, partly because Of the re-
treat Of the ocean. 3. As continents are
formed, part of the, water Of seas is
transported to them in the form Of lakes,
rivers, eternal SHOWS, glaciers, and or
ganized substance. Owing to these &C,
tions the water Of the ocean has diqlu,,
ished in a constant manner, and its level
has been lowered. 4. In proportion as
the earth o0ols, ice accumnlatas near the
poles and on mountains, water is i'm
bibed moro deeply into the terrestrial
crust. and the formation Of hydrated
minerals is manifested everywhere. It
results from al these facts that since
water existed on the earth's surface the
level of the sea has been gradually low

-Theswesther is an ever-present topic
Of interest, rendered unusually attractive
by the anomalies of the present season.
Generally considered, the earth ) climate
may be said to have two sources-the
heated belts Of the equator and the cold
districts Of the poles. Between. these re-
gions currents of air are constantly cir
culating.s The cold arctic currents sweep
to the tropics, chilling the lands over
which they pass, while the mild winds
from the equator exert a corresponding
influence upon local temperature. It has
been claimed that mild and coldawinters
may lie directly traced to the prevailing
winds-it being found that an air current
once established in a general direction
north or south often continues during an
entire season, with brief variations. If
this is the case, the discovery of the laws
governing the circulation Of the air cur
rents and their. disturbance will be an
important advance in meteorology. Prof:
Piazzi Smith, the eminent astronomer of
Scotland, believes mild seasons to be due
to: solar influence. He supposes the heat
waves to attain their greatest degree
shortly after lninimum Of spots on the
sun [the last sun-spot minimum was
passed some months ago); the cold waves
to be due to terrestrial causes. Like
other sun-spot theorists, Prof Smith
points to remarkable condolences of the
"sun-spot period of ten or eleven years
and the supposed cycle of warm and cold
seasons. ss5ts *st+5f
