photographs and other pictures are
transmitted as cipher messages over
ordinary telegraph lines by the new
process of Emile Fortong, a German.
The picture is inserted in an electric
apparatus, which automatically de-
composes and registers the consecu-
tive elements of the image, tie record
for each element OF point being a
number or figure, which is perforated
indicate in proper order the cJIot
values or shades un scale of five
degrees or more. When the record is
received through auy telegraph office,
it is taken to the second instrument,
which has keys like those of a type
writer, and on striking the keys
corresponding to the successive num-
bers, the operator obtains in half an
hour a printed and enlarged repro
duction uf the image.
Surgical grating, still in its in
fancy, has extended with the develop
ment of antiseptIc methods, and now
includes tissues of all kinds, parts of
organs and even entire organs. Prot.
Garre cites the successful transplant
ing of pieces of skin as large ss the
palm of the hand, of the tip OF toe
upon MANNED finger, of fatty
tumor to replace an amputated breast,
of pieces of veins and arteries, and OF
kidneys. Bone grating has become
of great Importance. The thyroid
gland of woman was transplanted
upon the spleen of her four year old
idiot child, and the astonishing result
was that nine months later the child
was developed mentally and learning
to walk and talk. Muscle, sinew,
nerve and teeth gIaftings have failed.
The deviator of NJ Jansen is float
designed to change the course of a
kite and take tow-line to vessel in
distress. In late experiments at
Royan, France, line was carried to
ship a third of nile away in
four minutes, with deviations of 60 to
70 degrees from the direction of the
wind.
The form of electric lamp now
being developed by the inventors of
the Helion tiIament- Prof. Ii. G..
Parker and W. q. Clark is intended
for constant pressure circuits, and
genera ates light from a conducting
film lining the bore of small quartz
tube. A feature is that the quartz
tube permits the passage of the short
wave-lengths of ultraviolet light, a
quantity of such rays being given off
by the conducting film. The efiici-
ency of the lamp is increased by coat
ing the surface with thorium oxide.
Under the combined influence of the
heat and the ultraviolet rays this
coating glows with the characteristic
incaudescenee of the Welsbach mantle,
and powerful light isyproduced with
great economy of electric energy.
The aurora boreaIis is attributed tc
cathode rays by both Prof. BirkeIand
a Norwegian, and M. Willard, {
French physicist. In some expert
ments by the former, the earth ha:
been represented by a spherica
| electro magnet wrapped in copper fol
spread with barIum platino-c ide
on exposure to pencil of cathode
rays, and on exciting the magnet The
| light seemed to concentrate round tht
poles and threw out auIoraI stIeamers
1he difference between the twt
theories is that one supposes th
cathode rays to come from the sui
while the other assigns to them
terrestrial origin.
Refrigeration of powder magazine
is suggested by Oh. Teller, Frencl
engineer, as safeguard against sue
explosions as that of Montfaucon
| France. This occurred on Sept. IL
and seems to have been connectet
with the intense heat of the last @
August. the extreme influence c
which could not reach the magaZin
through several yards of earth unit
after considerable time. 1t is cen
tended that cooling to 40 degrees G
so degrees f. with the apparatus no.
