Il has been found that by passing
mixed hydrogen and carbonic oxide over
nickel and cobalt they can be separated. .
Thensby applying the hydrogen to strip

An installation of electric light Is be-
ing laid down in the Batignolles Tunnel
near Paris, France, in which the incans
descent lamps are placed at height Of
about fifteen feet above the rails. The
light is received by plates Of FURNISHED
tin covered with glass, which reflect 2
soft and agreeable light into the carriages.
Long distance photography is rendered
quite successful by a new camera with z
telescope objective, which consists Of
concave lens of short focus and conysS
lens of considerable length Of focns.
These are put at a certain distance apart
depending on the difference of the two
foci. By the laws Of optics this arrange;
ment projects an inverted image OF "a
object at long distance from the lenses.
A photograph by DR.. Gill, presented
to the Paris Academy, shows from
10000 to 10000 stars, besides two
nebule, in an area of four square de-
grees. The exposure was over three
hours, instead of one hour as arranged
for plates of the international chart oi
the heavens and if such exposure were
possible for the entire man, it is thought
that 300,000,000 stars would record
their existence, instead of 80, 200, 900. IS
