The Magnetic Sense.--Prof. w. f.
Barrett, Of Dublin, states that certain
individuals have really appeared to
experience peculiar sensations when
near powerful magnets, and points
out that the magnetic sense which Sir
VIM. Thomson believes to exist may
be apparent i'll some persons and not
so in all. He gives several instances
in which persons have been able to
tell, by al unpleasant sensation in the
| head, when the electric current was
passing through an an electromagnetic

tainly does perceive the influence of Il
powerful magnet when his head is
near it, the keenneSs OF the magnetic
sense if such it be, varying consider
ably on different days, and being most
acute in this person when he is suf-
fering from facial neuralgia.
Mr.. Geo. II. Barton states in science
| that the lava stream which burst
from the side of the Hawaiian volcano
of Mamma LOa on the 9th of NOVem-
Der, 1880, continued to flow slowly
down the mountain and across the
country for more than nine months,
at the end of which time it had eX-
| tended over distance of about As
miles. A part of it's course passed
through forest, where the lava be-
came sufficiently solid before the
large trees were burned to retain
complete moulds of their trunks, and
from these perpendicular moulds the
| lava was found to average twenty
feet in thickness at this point. MI.
Barton roughly estimates the quantity
Of lava emitted at something more
than 500,0O0,000 cubic yards. The
rapid cooling and solidifying of the
surface Of the lava while the interior
was still flowing caused a considerable
part Of the stream to take the form Of
| a tunnel.
The art of sewing has been known
from very remote period, as is shown
by the fact that bone needles have
been found among the oldest remains
of the Swiss lake-dWellings and i'll the
caves Of France and Great Britain
| which were frequented by man dur
ing the reindeer age. Some Of these
early needles were perforated in the
middle which WAS the thickest part
and others were pierced at the larger
end. y French cavern has yielded
needles much superior to those of the
ancient Gauls and to the ivory need

pecial skill having been applied to
the bearing of the eyes, which must
have been done with fine flint drill.
The Swiss lake jewellers used linen
thread or bark fiber for sewing, and
made garments from woven fabrics
OF linen and bark as we'll as from the
skins Of animals. The cave people
employed thread made from split
tendons and perhaps strings Of gut.

they performed some more delicate

has been suggested that we should al
so have sense which can perceive
the remarkable force which is exer-
ted by magnets. Every schoolboy
knows how iron and steel ale attract

piece OF copper OF silver is dropped
between the poles of a powerful elect
ro-magnet it falls slowly as if sinking
through mud. TQ determine how

Thomas declares that the result was

unwilling to accept this experiment
as conclusive, and thinks that it may

Revelation of the Deep.-In it's
cruise last summer off the coasts of
southern Europe and northern Africa
the French steamer Talisman found a
surprising abundance eff animal life at
great depths in the ocean. Many
forms new to silence were brought on
board. A remarkable feature of some
of these creatures is seen in their pc
culiar organs, some OF the fishes hay
ing curious mother-of-pearl colored
bodies imbedded in the skin of the
head, sides or back, and appearing to
be producers of light and possibly ac-
cessory eyes; while others have long

to the surface from the tremendous
pressure of the deep-sea, the expansion
in the bodies Of many fishes caused
their scales to fly off, their eyes to be
squeezed from the sockets and their
air bladders to be forced through their
mouths. The greatest depth from
which q fish was taken was 1852 faith
oms, specimen having previously
been secured by the Challenger expe-
dition from depth of 1874 fathoms.
Among the geological results of the
French party's dredging was the find
ing of polished and scratched stones
on the sea-bottom between France and
the Azores. showing that icebergs
must have existed in that part of the
Atlantic during the glacial PERIOD to-
gether with the bringing up of rock
fragments bearing impressions of
trilobites, which may be taken as evil
dence of the former existence of the
traditional lost continent Atlantis.
