Automatic Delivery OF Letters.
An invention which is exciting a
good deal of interest on the Continent,
where the fat system of residence is
so much in vogue, is an automatic
electric letter and paleel deliverer,
produced by q resident of Geneva.
As its name implies, the apparatus is
designed to distribute automatically
on each floor, and to all the tenants
of house, theIetters or parcels which
may be addressed to them. A large
box situated on the ground floor con-
tains AS many apertures as there are
floors or tenants in the house. When
a letter or other object is introduced
into one of these openings the box
rises and, in passing, distributes in
each of the addresses the articles in
fAH6A6 f0H %hono oanh 70, baioU in,
turn advised of the arrival of the
article by the ringing of an electric bell.
The working of the apparatus is ex-
tremely simple, an the following few
details will show, and its cost is in
significant. The object introduced in
to the box on the ground floor effects,
at the top of the house, an electric
contact, which opens the valve of q
water tank. The water fills cylinder.
which serves as counterpoise, and
raises the letter r-box, which, while in
the act of passing each private box,
opens itself by an ingenious yet simple
mechanical arrangement, and depos-
it's the respective contents therein.
When the box carrier has arrived at
the top floor the cylinder empties it
self. and the boz descends to it's place
and is ready for another trip.
Photos Sent by Wire. =
The transmission OF pictures by
electricity is one Of the latest applica-
tions of the subtle but extremely use
ful fluid, and the principle of this new
discovery is somewhat similar to that
on which the telephone is based, use
being made of varying degrees OF light,
instead OF sound, as in the tele-
phone. In order to send picture
over a wire it is first photographed
on what photographers call a
stripping film, composed of gelatine
and bichromate of potash. After the
picture is transferred to this finn the
film is washed with lukewarm water,
by which all but the lines of the pict-
ure are removed. leaving the photo
graph in relief.
The point OF tracing apparatus,
when drawn across this flm from side
| to side, rises and falls as it strikes
each line OF tine picture. This wave
| like motion of the tracer is made use
Of to produce similar motion in
another tracing apparatus at the
other end of the line by means Of
| complicated electrical mechanism,
and each depression and elevation in
the picture is reproduced in a waxen
cylinder on the receiving instrument.
To accomplish this it is necessary to
go entirely over the picture that is
being transmitted, tracing lines across
the surface. A single line conveys no
idea of the picture, but as they follow
each other they gradually outline the
object.-From Electricity. s.->,<
An Electric Fog Consumer.
CAT midnight last noticed flashes
of lightning illuminating my bedroom.
A camera wasloaded and an excursion
into the country taken, hoping to
obtain a few new photographs of
Jove's handiEork
1.-THE night was very foggy, and the
flashes of light (very frequent and
vivid) gave only blurred images OF
trees in the foreground.
cat 1:3O in the morning as / was
about despairing of obtaining photo
graphs, a sudden streak of lightning
shot right through the fog, followed by
heavy peal OF thunder, and in less
than thirty seconds the fog had en-
tirely disappeared, being precipitated
by the electricity in the atmosphere.
"In these rain producing days per-
haps some inventive genius will take
hint from this occurrence for the dis
sipation OF q fog on a large scale by
introducing large powder-driven Holtz
machines on shipboard and sending a
stream of electricity into the fog-lad-
en- air from various points along the
rigging. thus producing clear area in
the nelghborhood OF the vessel. And
who knows, perhaps, by theextension
Of the system, some day we may see
