expected to make my fortune by this
scheme, but an experiment completely


undeceived me-" Putting carp into a


freezing mixture, he observed, in fact,


that, after being entirely frozen they
were dead, past recovery. The case is
the same with all other animals, as the
late and very remarkable efforts of f.
A. Pouchet have proved.


WHAT ARE CYCLONES ?-Professor T.


B. Maury, in recent article on the


subject, said The word cgclone has


frequently, but incorrectly, been used


rs significant Of nm enormous or very
violent meteor, as if its application was
to be confined to the devastating hurri-
cane of the West Indies or the terrible
typhoon of the China seas. 1t simply
means a storm which acts in a circular
direction, and whose winds converge,
by radials or sinuous spirals, toward a
centre, moving in our hemisphere in
the opposite direction to that of the
hands of a clock, and in the southern
hemisphere in contrary direction.
Taking this as the definition of cy-
clone, it seems clear, from observation
alone, that all storms are to be regarded
as cyclonic. Volumes have been writ
ten to prove that this is not the case.
But we have only to examine a few
series of weather-maps from week to
week to see that, wherever you have an
area of low barometer, into its central
hollow the exterior atmosphere from all
sides will pour, and that in so, doing
rotary spiral or vorticose storm is gen
Grated. The tornado, the simoons, the
dust-whirlwind, the fre-storm, even the
slow and sluggish storm which moves
on our Western plains as the laboring
wheel of the steamship buried in
heavy sea, all attest that body can
not move on the earth's surface in
straight line. 1t is not more true with
us that the Gulf Stream turns to the
eastward, the Polar Stream to the west
ward, and the equatorial currents to
the northward, than that every air-cur-
rent, in obedience to the same law,
should turn to the right of the line
along which from any cause it is called
to move. The meteorist has therefore
only to ascertain by observation where
the barometer is lowest, to know at
once the direction of the wind from the
circumjacent districts, far and near, or
at least to test the mathematical law by
q grand experiment.


TRANSMISSION OF BLOOD. THE follow
ing is from the Popular Science Month";
~ for April The first experiment was
tried on II man aged twenty. He was
beheaded at 8 o'clock in the morning;
eleven hours later all traces of irrita-
bility had disappeared from most OF
the muscles of the body. Injection In
to the muscles was begun at ten min
utes past 8 in the evening the quanti-
ty of blood (Which the operator took
from his own veins) was enough for a
limited part of the body; he therefore
confined his experiments to the hand.
Injection was made by the artery in
which the pulse is usually sought, a
little above the wrist, and of course, in
the direction of the tingers;i it was urged
at first quite fast, then slowly. The
blood, which went in bright colored,
passed out dark from the vein, as is the
case in life. The operation continued
thirty-fiye minutes, and, ten minutes
after that time, irritability had return
ed u movement in the musclas OF the
hand could be artifcially excited. With
the second subject, injection OF the
blood of healthy dog was made; the
blood had been first deprived OF its CO.
agulable matter, and beaten up IN the
air; there was about pound OF 1t.
The subject was strong man forty
wears old. Death had occurred at 8
o'clock in the morning at twenty-five
minutes past 10 in the evening rigidity
was complete, without a trace OF co
tractability under the influence OF sum
illus. The arm was amputated, and at
twenty minutes past II Brown-Sequard
effected injection by the brachial artery.
The skin'at first took livid color, but
very soon the roots of the hair grew
erect, giving the effect of goose-fesh,
as it is called. This artificial circula-
ton wasso entirely successful that the
veins OH the back of the hand presented
a BLUSH tinge; beating like that OF
the pulse lifted the main artery oil the
wrist muscular life revived; the fingers
soon lost their stiffness, and forty-tive
minutes after IL irritability had reap
peared in the muscles of the arm; 1t
was still perceptible at 4 in the morn
ing of the next day.
