of the finding of remarkable remains
of gigantic birds in Argentina double

The largest asting ever made id
India was the anvil-block for new
steam-hammer, which was recently cast
at the Jamalpur shops of the East In
dian railway. The block was cast close
to the spot where it will be used, and
weighs about thirty-eight tons. The
iron used was mixture of Indian iron
and imported (English) pig.

One singular property of all ami
NAL bodies is that of maintaining with
In themselves an equa1le temperature.
The blood of the Arctic explorer fes
mains at a normal temperature, though
he breathes air that will freeze mer-

ture of the air is lis to 100 above zero,
the temperature of the blood is still %
degrees Fahrenheit.
Paper tough as wood is said to be
made by mixing chloride of zinc with
the pulp in the course of manufacture.
1t has been found that the greater the
degree Of the concentration of the zinc
solution the greater will be the tough.
ness of the paper. 1t can be used for
making gas pipes. boxes, combs, for
roofing and even, it is added, for maxi
ing boats.
"A French vegetarian society, like
ancient Gaul, has become divided into
three parts One wing calls itself
cerealite, to indicate that it believes
only in eating cereals; another will be
known as Unitarian, because it thinks
fruit the only proper food, and another
has been dubbed tuberile, because it
believes in eating roots. Each wing
thinks that the happiness and stability
of the human race depends on the
adoption of its view&-N. Y. Tribune.
Mr.. Glaisher, the aeronaut, asserts,
after long and patient investigation.
that the ninth day of tho moon is tho
most rainy Of the whole twenty-eight,
and that in the first and last weeks Of
the moons age the rainfall II less than
the average. The records kept by Mr..
Glaisher also indicate 1 o'clock In the
afternoon a. the rainiest hour In the

during the past year astronomers
have discovered 30 new planets. OF
this number two were found by Palisa,
the veteran asteroid hunter Of vi
emma" The remainder were appraised
by means of photography. Daring the
three opening months of the present
year % planets have been added to the
list The total number of asteroids
known on April is 374. Astronomers
are confident that the number WIN be
400 before the close of the year.
Snakes do not bite" says New
Orleans physician who has studied
snakes considerably. They can't, he
says, because their jaws are connected
only by cartilage, are not hinged, and
cannot be brought together with any
force. The snake simply hooks the
fangs in its upper jaw into the object
aimed at, the lower jaw not figuring in
the act at all. The act is very similar
TO that of man striking a cotton hook
into bale of cotton, or q boat hook
into pier.
AS long ago as 1888 years before
Christ, Alexander the Great employed
mirrors to convey signals by the light
Of the sun. Since the time of the great
warrior the idea has been reduced to q
science and called photography" The
heliostat, an instrument invented in
Holland early in the eighteenth CEN
fury, and the heliograph, invented by
Manse in 1875, have both been used BY
The British army in their eastern cam
paigns. The instruments mentioned
1iffer somewhat in construction, but
the results are the same no matter
which instrument is used. In both
signals are produced by causing q re-
aected ray of the sun to appear and
disappear alternately at q distant
point, the intervals of appearance and
being carried in lengths 80
