member Of the faculty Of a Western
university has announced that he has
succeeded IN very materially reducing
the cost Of lithium. The fall details
of the method have not been disclosed,
but electricity is the method By which
the metal is separated
The Lick Observatory has done won
asrs in photographing nebulm, the
sun and its corona. The party from
this observatory was most successful
rs ia observation Of the SUMS eclipse
ia india last January. 1T was ascer-
tanned clearly that the sun spots are
due to solar activity, and that the
earth only intercepts one-haii a mill
lionfh part Of the heat radiated by the
sun.
The great telescope which viii be
seen At the Paris Exposition is in
tended to surpass the most wonderful
instrument Of this kind ever before
constructed It is to be the longest
one ever made, and to construct a
buildinQ high enough for it would be
a verv great expense. It has, there
fore. been planned by NJ Gautier to
have large mirror. six aud a half feet
ia diameter, reflect the rays thrown
upon it, so that the instrument can be
used in a horizontal position.
Lord Kelvin in conjunction with Pro
fessor Archibald Barr has recently
been investigating the subject OF the
disposition OF town refuse for the city
Of Glasgow to discover a method
whereby It might be gotten rid Of with
profit to the city. They found that
not only could refuse aud garbage be
consumed BY fire without a nuisance,
but that power to drive eleetric-hght
and other machinery could be obtained
without the employment Of coal or
coke. aud with absolutely no smoke.
After an examination Of the methods
used in different localities they found
that with a proper system the waste
products would yield residual sab
stances Of considerable commercial
value, andthe operation conld be made
one Of considerable profit 70 the muni-
cipality.

uninterruptedly upon it, through air
devoid OF an moisture With this in

requisite, by storing the sua's heat
This consists of large conicaly
shaped reflector Of highly Furnished
copper which has located In its centre
a boiler made Of heavy glass. The
heat obtained is stored in a reservoir

covering. which is said to ehectually
prevent the heat from radiating while
retaining it in the sand until it is re-
auired: and the reflector may be moved
backward or forward in a horizontal
? plane by means Of a lever, while pair
Of coz wheels running in a toothed
rack enables it to be elevated OK de-
pressed. In operation, the conicaily
shaped funnel is set at the proper
angle facing the sun, and the heat con.

directions Is transmitted to the reser.
