SCIENTIFIC SCRAPS

Two French dentists extract tee til
without pain BY spraying the external
ear with ether.
| A unique electric machine is capable
of cutting and buttering 750 loaves of
bread an hour, saving much butter.
An instrument has been invented in
Prussia by means of which an exact diff
ferential diagnosis of diseases Of the
lungs will be possible. The inventor is
DR.. Janiczewski.
An electric vegetable is said to have
been discovered in India, which has the
power of affecting the magnetic needle
at distance of twenty feet when the
weather is clear and dry.
With the view of testing the rapidity
of electric welding, twenty pieces Of
one-inch common round iron bars with
rough ends were recently welded to-
| gether by two men in thirteen minutes.
1t is claimed that wall paper can be
made in such a way that the passage of
low w-tensions electric currents will heat
it moderately warm to the touch and
diffuse throughout the room an agreea-
BILE temperature.
A further step toward the artificial
production of the diamond has been
made by passing an electric current
through carbon electrodes in cell con-
tanning fine white sand and electrodes,
the whole being under considerable
pressure.
The application of hydraulic power
to the manufacture of steel seamless
boats is one of the latest things in Eag-
land. These boats are thought to be in
every particular superior to those made
of wood, and can be made at about the
same cost.
1t is now proposed that London shall
dig the deepest hole. The pit would
have an elevator and DO lighted by
electricity, and in each stratum would
be excavated museum for exhibiting
spccime ms of the minerals, fossils, etc.
afforded by it.
The conclusions reached by modern
meteorologsts are that cyclones of
great intensity are ascending spiral
whirls of wind having a rotary motion
t. h.
sphere opposite to the movement of the
hands of a watch.
The yield of the trout spawn in the
fish bree ding establishments at Orval.
Belgium, is stated to have been ex-
ceedingly good this year. or the yield
70, 600 eggs were sent to this country
in exchange for like number of Cali :.
fornia trout eggs.
Inquiry made in France in order to
carry out the new law giving certain
advantages to fathers Of more than
seven children has elected, among
other things, the fact that there are
1000, 600 households in which there
has been no child.
Experiments recently made in France
with view to discovering the vitality
of trichine show that even when ex-
posed to temperature of 20 degrees TO
25 degrees below zero for about two
hours the little animals become as lively
as ever on turn 10 normal tempera-
ture.
Professor Poe of Bridge port, Conn.,,
has drowned and resuscitated d pet rab-
bit eleven times, and suffocated it also
with the fumes of burning charcoal and
restored it to life. The professor uses
a pair of artificial lungs. Artificial
respirations produce mus cular contrac-
tion and expansion, forcing oxygen
into the lungs and drawing out the
deadly gases.
Modern chemistry shows that the
medical lore of the an cient herbalists
had a much sounder basis than had
been imagined. In 1892 water crosses
were recommended for the cure of
scurvy and scrofula. Chemists now
say that the cress con tains sulphur,
phosphorus, iodine and iron - sub
stances that are known to be actual
