factory during the last year that
French officials and geographers plan
to establish pigeon post through
out the Congo. The first line is to
be 800 miles long, with four pigeon
houses 40 miles apart. Taken 100
miles, bird can return home in
about ~ hours. The flight of each
pigeon is to be limited to 40 miles,
but with proper distribution of birds
it is calculated that letter can be
carried 600 or 700 miles between dawn
and dark. The telegraph of the
region is made unsatisfactory by
thefts of wire by the natives and pull
ing up of poles by the elephants.
In the production of engraved
plates by telegraph, Carbonelle, a
Belgian, uses picture prepared with
thick non conducting ink, and this is
wound upon revolving cylinder
under stylus in electrical connec-
tion with the telegraph line. The re-
ceiving cylinder is covered with some
soft metal like lead, over which is
stylus that gives a cut varying in
depth with the intensity of the cur
rent from the stylus. The resulting
plate is ready for the printing press
without change.

physician, in X-Iay pictures. In
Photograph of a living person the
stomach and intestines are not visi-
BILE, but the stationary condition of
these organs and possibly the de-
velopment of gases cause them to
stand out clearly in the pictures
taken Immediately after death. The
distinctness increases with lapse of
time after death.
An astonishing bending of glass
under exceedingly small pressure has
been noted by Douglas Carnegie, an
English experimenter. Coating with
collodion silver surface mirror on
patent plate one-twelfth of an inch
thick, lie held the mirror by one of
the rubber suction holders used by
photographers in vanishing plates.
Interference colors, in series of
concentrlc circles, appeared over the
suction disc as the collodion harden
cd. The only explanation seemed to
be the almost incredible one that
the slight suction of the holder
caused All appreciable concavity Of
verified by rejecting the light of a
lantern from the mirror to screen.
La the larger reflection appeared
brighter interior disc, which changed
position as the holder was moved.
Saturn's rings are turned nearly
edgewise to the earth, for the first
time since 1891, and several American
astronomers have been studying GER
tain knots that are to be seen on what
formerly appeared smooth rings.
Prof. Lowell has suggested that this
indicates dlsintegration, portions of
the rings having fallen to the surface
of the planet. DR.. S. A. Mitchell
offers the reassuring prediction that
Saturn's rings will appear as beauti-
full to or grandchildren as TO us now,
demonstrated sixty years ago that the
rings must consist of millions Of tiny
satellites rotating Independently
finding it easy to show that there
may be crowding in some places.
The total number of electrical
patents issued in the world, except
ing Russia, is placed by German
authority at about 5O00 per year, the
actual average for 1904 to 1906 having
issued to citizens of the United
States, and $50 to those of Great
Britain and its colonies. Germany
issues 800. about 200 of them to
foreigners, and it is pointed out that
the alert German electricians gain
the free use of the bulk of foreign
electrical Inventions.
Perhaps the most novel and inter
esting electrical kitchen in the world
is that in the Jungtrau district, at
height of more than 10000 feet
above sea,level. 10 get fuel in this
desolate region is a matter of diff
Guilty, but the engineers have estab-
lished high pressure electric trans
mission line, and current to do the
cooking is taken from this line.
Transformers reduce the pressure to
