ment that Brown Sequard once inject
ed the head of dog, after being sega-
rated from the body, with dehOnuated
and oxygenated blood, and at the mo,
ment when the injection of this blood
had recalled manifestations Of life he
spoke the dogs name. The eyes OF the
head thus cut from the trunk turned
toward him, as if. the masters volc-
had still been heard and recognized.
In some interesting experiments DR..
Liebenbcrg has shown that the pres
ence of lime in the soil is absolutel
necessary for the termination of many
plants, while many others do not seen
to require it at all.
The Central Bureau Of the weather
service of France receives, daily, 97,-
600 kilograms from foreign parts, aud
$4,000 from France. FIR IN these toe.
graphic reports the weather probabili-
ties are calculated for eight agricultural
and four maritime districts, to which
warnings are telegraphed. Eighty'two
per cent. Of the predictions thus sent
out have ben justified
The question of the existence Of
earth.tides, or oscillations OF the earlh's
crust corresponding to those produced
in the sea by the attraction of the
moon, is being investigated by Brit,
ish commission. A pendulum is so
suspended that its slight st motion
turns mirror and causes the point of
light reflected by it upon a distant
screen to move very perceptibly. The
pendulum is proved to be IN continual
change Of position, for the motion Of
the reflected light is hardly pos-ible to
determine its mean position on the
screen within five or six inches.
The French physiologis s, Pcrrier
and Poirier, have found that, properl,
speaking, star-Cshes have no bio d cir.
culatiou at ell, as what has hitherto
been supposed to be the heart i'll tLeese
animals is simply a gland.
It has been noticed that wines, es-
pecially when hard aud acid, arr i'm.
proved in flavor by the passage of an
electric current through Them The
electricity is claimed to have the SAINT
effect as age, mellowins the wines ny
the decomposition Of the bitartrate of
potash.
The electric light was used in re-
cent search for three persons who had
lost their way in an attempt to ascend
peak of the Alps. The use OF the
light was not successful, but the idea
seems to have been u good one. and in
many similar cases might serve 10 di-
irect the wanderers.
The tensile strength Of glass has
been shown to be between 1900 and
5000 pounds per square inch, arid the
crushing strength between 5000 and
10000 pounds per square inch. by
trials a short time ago, NJ. Traulione
found that flooring glass, che inch
square and one foot between the end
supports, breaks under load Of ITO
pounds.
A large fortune of several million
francs was left by M. Henry Clifford,
the eminent engineer, who recently
died at his home in Paris, to the French
Government for use in promoting the
progress of scientific discovery.
An English gentleman has exhibited
hyacinth which, in consequence f
being under stone, h ID b!ossomed x
inches below the surface Of the ground.
The leaves were white, but the flowers
were deep purple.
Camels live from forty to fifty years;
horses average from twenty five to
thirty; oxen, about twenty; sheep, light
or nine; and dogs twelve to fourteen.
Concerning the ages attained by non.
domesticated animals only few ,solas-
ed facts are known. The Eas, Indians
believe that the life period of elephants
is about 800 years, instances icing re-
corded Of these animals having lived
100 years in confinement after capture
at an unknown age. Whales are "a,
timated to reach the age of 400 years.
Some reptiles are very !onglved, an
instance being furnished by a tortoise
which was confined in 1888 and existed
in 1853, when it persisted by an acci
dent. Birds sometimes reach a great
age, the eagle and the swan having
been known to live 100 years. The
longevity Of fishes is often remarkable.
The carp has been known to live 200
years, common river front, fifty years;
and the pike ninety years. while GEES
ner-a Swiss acknowledgements that
pike caught in l497 bore a ring re-
cording the capture of the same fish 2G7
years before. Insects are very short
lived, usually completing the term OF
their existance in few weeks OF
