SCIENTIFIC MYscELLANY

The view is quite generally accepted that
the well-known COW pox, or vaccinia, i,
smallpox attenuatcd in some unknown
manner by its passage through cattle
BY passing the bacillus of the destructive
"rouget' Of pig, through serie, Of rab
bits Mons. Pastenr has recently succeeded
in getting similar attenuation Of that
virus, which will give pigs a mild form
Of the disease and will render them Sc
cure from further attacks in any degree
He has also found that when the ''rouget"
buc;llus is passed through series Of pig
cons its virulence Is increased, 50 that
pigs inoculated with the virus Of the last
Of the pigeons have most intense form
Of the disease. Pastcur's famous inocu-
lations of domestic animals with anthrax,
or splenic foyer, have been made with dis
ease virus attenuatcd in another way
that is, BY successive civilizations in suit
able liquids.
Mons. +. f. Blavicr fiuds that, con-
trary to the general opinion, underground
telegraph lines are not more influenced
by earth currents than are Drial lines.
OF the 10000 bronze articles which
have been found among the remains of
the Swiss lakc-dwellcrs about 30 per cent.
arc rings, II per cent. bracelets, four per
cent knives, three per cent needles, GA
per cent. hammers. and OF per cent
fbulm.
Observations made during Ave months
Of last year, by German physicists, indi
cate that the heat given out by the sun
is diminished by the presence of spots on
the solar disk. Much further research
will be necessary, however, before any
valid conclusion can be reached concern
ing the effect Of sun-spots upon solar tenn
perature.
Mons. Ogata, French Psychologist,
has made somo!remarkable experiments
showing that the process of digestion may
be quite satisfactorily accomplished in
animals without the aid of the stomach.
Nearly the whole of the stomach was re-
moved from dog, the free edges of the
alimentarystube being then scwed togeth-
or. The dog completely recovered from
the operation, aud remained in perfect
health, with good digestive powers, unit
killed six years afterward. In other ex
periments upon dogs it was found tina,
albuminous substances were as spccdil,
and completely digested by the fluid o.
the intestine below the stomach as by the
secretions of both stomach aud intestine
together, but other food: swerc less readily
digested in the intestine.
Photography has made great progress
aimee the days Of Dagucrre, and there art
few objects Of which photographs canno,
now DO made Minute tilaments, far toe
small to be seen with the naked eye, have
been photographed with a photomicro-
graphic camera. Under the Illumination
ef spark from Leyden jars, picture
has also been obtained Of the vibrating
point in the diaphram Of a telephone while
person was speaking at it, although the
work must have been done in one twenty,
four-thousandth part of a second.
Letters to the Royal Geographical So
ciety, Of London, state that MIR. W. w
Graham, with two Swiss guides, has sue.
cesded in climbing Moust Kabru, in the
Himalayas. This peak has an altitude
Of 24,O1S feet, aad its summit is claimed
70 be much higher than any other land
yet reached by man. The mountaineer'
resort that neither in this nor in the sew
eral other mountain ascents made BY
thcm in the same region did they expr-
fence the slightest Inconvenience from
rare6ed air.
From freshly-fallen snow, the symbol
Of absolute purity, Swiss microscopic,
Floegel, has obtained living infusoria and
alge, 'baeili and micrococci mites, dia-
toms and great numbers of fungi spores,
also 6bres of wood, mouse hairs, pieces OF
butterfly wings, skin Of the larvae of in
sects, cotton-fibers, pieces Of grass, cpl
dermis, pollen grains, rye and potato -four,
grains Of quartz, minute pieces Of rooding-
tiles and bits of iron and coal.
The Paris Academy of Sciences has
received the report Of the French scien-
lists who recently visited Cape Horn and
explored the southern islands of the
Fuegiaa archipelago. The expedition en-
countered only five mammals-a fox an
otter, two rodents and the domestic dog.
Forty species of birds were seen, and a
