SCIENCE AND INDUSTRY.

-Pasteur's plan of exterminating
rabbits by inoculating them with chick
en- cholera has been tried at Rheims
with success.
1t is stated that several diamonds
were found in meteoric stone, weigh
ing about fourpounds. that fell in Kras--
nolobodsk, Russia. This discovery has
set people to examining meteorites with
unusual interest
The artificial production of chickens
is great industry in Franklin county.
Pennsylvania. Over 700 incubators are
in operation and the production is from,
10, 900, 900 to 10000. 600 chickens annu--
ally.
The advisability of testing as foggy
weather signals sudden flashes, such as
those of gunpowder, has been suggest
ed to the British lighthouse authorities
by Lord Rayleigh and Professor Stokes,
who think the flashes might attract at
tention where an equal fixed light might
escape notice.
An instrument called the auto
graphometer has lately been devised
which autographically records the plan
of the ground over which it is dragged
1t can be carried about on light We

There are about five hundred diff

America they range north to the Arctic
regions and south to Patagonia; and
from the level of the sea to the height
of the Andes.
"A noted scientist has shown to- the
Ophthalmological society of Heidelberg
his second success in grating the rab-
bits cornea into the human eye. The
patients visual power with the new
eye is about one-tenth of the normal.
and coarse print may be read.
Among the almost numberless-
methods of removing particles from the
eve, the following is recommended as
an efficient means: Make loop by
doubling horse-hair. Raise the lid of
the eye in which is the foreign particle;
slip the loop over it, and placing the
lid in contact with the eyeball, with
draw the loop. and the particle will be-
drawn out with it. t.-Scientifc american.
The Polytecinical journal describes.
a new kind of lubricant. One hundred
parts of mineral oil and twenty-five
parts of castor oil are mixed thorough
ly with sixty 10 seventy parts of sui
phuric acid, and the whole worked with
two or three volumes of water. In this
condition the composition is allowed to
stand some time, the watery layer is
then drawn off. and, after remaining
undisturbed for several days, it is care
fully neutralized with soda or potash.
1t is estimated that in the United
States alone during the year 1897 there
were manufactured and sold about half
million gallons of writing ink and
about four thousand tons of printing
ink. Of course a considerable quantity
of this was exported. and some ink of.
European manufacture was also inn
ported. But the Importation OF TINS
article is constantly decreasing as the
excellence of the home manufactures
improve and the market is supplied by
them ut cheaper rate.
1t is found that living creatures
brought up from sea depths of tour
miles or more. suffer greatly from the
changed conditions of pressure and
temperature. At those vast depths the
pressure is tremendous, and the tenn
perature is comparatively low. On
being brought to the surface, the deep
sea creatures are sometimes torn in
pieces bv the powerful expansion of
their organisms occasioned by decrease
in pressure. and sometimes they alb
solutely melt away before the eyes Of
the beholder."
