enc Vi TIE most Interesting inventions in

victoria, Australia. The apparatus CON-

principle, picture or the image on the
snounu grass Ct camera is held before a
system OF lenses, which focus it upon the
center OF glass plate, containing salenS
luin: before reaching the focus the waves
el hght pass through a revolving disk Of
llie al containing series of holes arranged

can transmit the focused light at The
same Tune. Hence upon looking through

corning to the strength of each light raw

manner each light wave issuing from each

Davis OF New York. The image tn he

rays are brought to focus upon a sieve.

lun, protrude through the meshes of the
sieve: After passing through they come

Across their exposed ends is placed q
copper plate, and upon this is spread a
sheet Of paper saturated with phenolph-
talein, alcohol and glycerine The electric
current being turned on, 1t is claimed that
the image. appearing before the camera is
reproduced upon this sensitive sheet. Ac-
core ing to the description of the inventor.
The 2Oo wires in the camera combine their

hitting wire, the same impressions being
sorted out automatically at the reA.iyina
END and distributed in the appropriate
wires leading to the copper plate
F. NJ Close, an inventor of Oakland Cal
lately made the announcement that he had
discovered the principles of an apparatus
whereby he will be able to see through a
wire, and not merely reproduce images
transmitted thereby. His invention is de-
scrlbed as consisting of a soft iron magnet
irclosed In a box, and connected by wire
with another soft iron magnet at the Other
cad. A candle or kght placed in front of an
Opening in one box excites a series of cleo
trio vibrations in the connecting wire The
vibrations are repeated in the receiving end.
where they are reconverted into light of the
original quality and form. The details of
f,fs discovery the inventor withholds from
the public until his satisfaction as to it's
perfection Is further gratfied
