SCRAPS OF SCIENCE.

A CURIOUS instance of the deodOrlzlng |
Of illuminating gas was recently cited by |
Prof. Rensen In Dresden quantity of |
gas escaped from pipe outside of a |
dwelling and passed through the earth |
into the house, with its odor entirely |
gone. 1t was breathed unconsciously, !
and several deaths occurred in conse-
quence.
SOME interesting archaeological dis
coveries have just been made in Algiers.
near the sea-coast, on the seat Of the an
Gent Utica The remains of a temple
consecrated to the infant Hercules; a stat
uette of the god in white marble, evil
IDENTIFY Greek; q Bacchus, life size, also
in white marble; and a number OF fine
mosaics, seem to indicate the probability
of great find. .
The great telescope just completed by
Howard Grubb of Dublin for the Vienna
Observatory is the largest refractor now
in existence The steel tube is thirty
three and one half feet III length, and the
instrument weighs near seven tons. The
| object glass is twenty-seven inches IN dl-
| ameter, while that of the great telescope
| at Washington, hitherto the largest In
| the world, measures twenty-siX inches,
The use of the electric telegraph IN
Arctic exploration seems excellent and
| practical BY such aid sledge parties
could be kept in communication with the
main body Of the expedition. The wires
would be made as light as possible, and
laid along the snow or ice or the frozen
ground. either of which would sufficient
" insulate the wires without the use of
the usual poles and glass insulatOrs.
AT THE Paris observatory Thollon is
carefully studying the suns surface and
has described number OF interesting
hydrogen explosions, appearing like 81
gantic displays of fireworks, and some
times remaining visible for two days.
One of them sent forth stream OF fire
to hight of more than 100000 miles
a distance nearly equal TO that Of the
moon from the earth--while explosions
, reaching to d hight of 5000 TO $4,000
miles are by no means infrequent,
AN ACCOUNT was recently given to the
British Royal Society. of the trans
Y planting of bone, the first successful
instance of the kind ever recorded 4
piece of diseased bone had to he removed
= from the arm of a boy of three years II
t a Glasgow infirmary. Fifteen months
t after the operation no new bone lorna
+ ton had appeared, and the experiment
:, of bone grating was undertaken. Oh
o three different occasions portions OF hu
! man bone were transplanted, the graft
being taken from patients from whom
u wedges of bone had to be removed 70
q the purpose of Strengthening their limbs
n These wedges were divided into man
- small pieces and placed in the child
:, arm. The fragments grew together an
u adhered to the bone of the arm abov
y and below, ultimately converting use
II less arm into thoroughly useful one b
the formation of a complete bone.
n SOME conception of the enormous ell
I'd ergy of the human heart may be forme
% when it is considered that good climl
N er can only ascend 5000 feet in nil
= hours-that is, working continuously f
considerable time, can only raise h
own weight | 200 feet an hour-whl
IN the work done by the heart is equlvel
7d to raising its own weight (ten ounces) Id
lg S60 feet high every hour. A stlil mo
al striking illustration of the great pow
n of this little organ may be found |
" comparing it with the most powerful e
D. CINE ever made by man-the Bayarl'
I locomotive, of the Vienna and Irles
he Railway-which can only raise 1tst
On through 2,7O0 feet an hour. That is,
is energy is less than one-fifth that OF t
N human heart. Of course, the actU
W. work done, by both engine and climbt

Is by the heart, but relative to the weigh
