Disease organisms appear to be
capable OF undergoing considerable
changes when reproduced under vary
ing environment. The we'll known
cow-pox, or vaccinia, is small pox
attenuated in some unknown)manner
by its passage through cattle. BY
passing the bacillus of the destructive
"rouget" of pigs through series of
rabbits Mons Pasteur has recently
succeeded in getting a similar atten-
uation of that virus, which will give
pigs mild form of the disease. and
render them secure from further at.
lacks in any degree. He has also
found that when the "rouget" bacillus
Is passed through series of pigeons
its virulence is increased, so that pigs
lnoculated with the virus of the last
of the pigeons have a most Intense
form of the disease. Pasteur's ia.
nous inoculations of domestic an.
finals with anthrax, or splenic fever,
have been made with disease virus
attenuated in another way-that is,
by successive civilizations in suitable
liquids.
Mons. E. E. Blavier finds that, con-
trary to the general opinion, under
ground telegraph lines are not more
Influenced by earth currents than are
aerial lines.
Observations made during five
months of last year, by German phys
icists, indicate that the heat given out
by the sun is diminished by the pres
ence of spots on the solar disk. Much
further research will be necessary.
however, before any valid conclusion
can be reached concerning the effect
OF sun-spots upon solar temperature.
Mons. Ogata, French physiol-
ogist, has made some remarkable ex.
perlments showing that the process
of digestion may be quite satisfac-
torily accomplished in animals with
out the aid Of the stomach. Nearly
the whole of the stomach was re-
moved from dog, the free edges of
tie alimentary tube being then sewed
together. The dog remained in per-
feet health, with good digestive pow
ers, until killed six years afterward.
In other experiments upon dogs it
was found that albuminous substances
were as speedily and completely di.
gested by the fluid of the intestine
below the stomach as by the sccre-
tons of both stomach and intestine
together, but other foods were less
readily digested in the intestine.
Photography has made great prog.
ress since the days of Daguerre, and
there are few objects of which photo
graphs cannot now be made. Minute
fiaments, far too small to be seen
with the naked eye, have been photo
graphed with a photomicrographic
camera. Under the illumination of a
spark from Leyden jars, picture has
also been obtained of the vibrating
point in the diaphram Of telephone
while a person was speaking at it,
although the work m ,st have been
done in one twenty. -thousandth
part Of second.
Letters to the Royal Geographical
Society, of London, state that Mr..
w. w. Graham, with two Swiss
guides, has succeeded in climbing
Mount kabru, in the Himalayas.
This peak has an altitude of 24,Ol5
feet, and its summit is claimed to he
much higher than any other land yet
reached 10y man. The mountaineels
report that neither in this nor in the
several other mountain ascents made
by them in the same region did they
experience the slightest Inconvenience
from raretied air.

bers of fungi spores; also fibers of
