totally different from that Of higher

animals. Ths 'tspiraelesp admit air
into two tubes, which run along the
sides OF the body. The insect does not
breathe through It's mouth or through
its nose, bat through the sides Of IL
body. II has 3 large number Of brains
through the body, which explains why
it is so difficult to kill an insect, as each
separate brain has to be destroyed.
Changes in thermometers, ranging as
high a eight to ten degrees have been
found to occur when applied TO certain
purposes, and kept at q high tempera-
ture for a considerable period
NJ. Goyard, a French physician, has
lately called the attention Of medical
men to a case in which a new born in
FAINT, apparently dead, was recalled to
life by immersion in a bath Of water
heated to 100 degrees Fahrenheit.
The influence OF the moon on the
temperature was the subject of a paper
recently read to the French Meteoro-
logical society by NJ. Coeurdeyache,
giving the result OF eight years. obser-
vations at the ST. Maur observatory.
Comparing the NEAR daily temperature
for the months Of March, April and
| May, he shows that the temperature
decreases until the fourth day after a
new moon, rises to its highest point on
the sixth fan average of 14S degrees),
falls again until the eleventh day ito II
degrees), then rises ito 14.4 dcgrees)
until the sixteenth day, falls again un-
til the twentieth or twenty-lrst Ito 10
degrees), then rises with slight varia-
tions until the end OF the lunar period.
Taking into account only the minima,
which are Of especial interest on ac-
count of night frosts. the moons in
fiuence is still more distinct. The
highest minimum mime degrees) occurs
about the sixth day, and the lowest
about three degrees) on the twenty
first. Thus, according to M. Courde-
vache's researches, night frosts are
most probable about the twenty-hrst
day Of the noon.
A wealthy merchant Of st. Peters
burg, Herr Julius Gillis, has offered a
prize of n thousand forms for a pop
ular work on "Kant's Views on the
Ideality of Time and Space"
Portable electric lighting machines
are being made in France, the steam
motor being employed at will to trans
port the machine or produce the light.
BY treating the wood Of the heather
or poplar with q hot solution Of alum,
a liquid Of a bright yellow color is pro-
duced, which deposits o greenish rosin.
This forms a new coloring matter,
called ericine.
A novel mode Of propelling vessels
has been described to the French acad-
envy by NJ. Grandt, who says he has
constructed an apparatus for the pur-
pose. The principal agent is electricity.
One or more sets of electro-dynamic
apparatus are driven by an ordinary
steam engine. The electric current is
sent through a voltameter containing
calculated water. The oxygen and
hydrogen arising from decomposition of
the water are led, in a tube, fore or aft,
in the boat, according to the direction
in which it is desired to 60. They
escape by an aperture in the hull, a lit
tie above which aperture is an induc-
tion coil arrangement, by which sparks
are passed between two insulated pla-
tinum points. The explosion of the
gases thus caused propels the boat.
May this idea not lead us to hope that,
after all our misgiyings, some use may
be found for hundred ton gunsp The
recoil produced by the rapid firing of
charges of several hundred pounds of
powder ought surely to make the CUPS
valuable as motors for vesselsl
L'Eletricite has taken the trouble
of devising a plan for producing spirit

microphone.
An agricultural experiment associa-
