A new substitute Tor ivory, called
lactite has been invented by Nor

milk. and will take any coloring.
The greatest monstrositv in chemi-

1t is a mistake to suppose that polar
research has cost enormously in human
life Despite all the great disasters.
ninety-seyen out of every 100 explorers

Every year Il layer of the sea four
teen feet thick is taken up into the
clouds. The winds bear their burden
into the land, and the water comes
down in rain upon the fields. to flow
back through rivers.
The works of watches are now plated

convenience of access recommends it
as a summer resort.
The heat produced from the light of

amount of caudlelight. The bugs
light is produced By chemical action,
as it is increased by putting the fly in
oxygen aud diminished in an atmos-
phere of nitrogen.
Scientists say the chemist will domi-
nate coming inventions. All our fuel
will presently be furnished in the form
of gas. In quarter of century more
we shall wonder why man was ever
such fool as to carry coal into his
house and burn it.
The olfactoneter recently exhibit ted

A new pianoforte key board having
six rows OF keys has recently been ex-
hibted in Manchester, England An
octave is formed by six keys in two
continuous rows. All the keys are on
the same level. and each note is sep
araLed from the next by an interval of
two semi-tones.
1t has been calculated that the cleo
tromotiye force of Il bolt of lightning
is about $500. 900 volts, the current
about l4,OOO000 ampercS, and the time
TO be about l-2O 600 part of second.
In such bolt there is an energy of
2, $50 900 watts, or 4, ISL 1872 horse
power
A curious phenomenon is reported
from Jewett City, CT. George Rood
was recently struck by a thunderbolt
and badly burned. and suffers intense
ly still. His whole body is so charged
with electricity that when he puts his
hands together they stick, aud only by
violent rubbing can they be separated.
If his feet touch it is the same. The
severe burns are beginning to heal and
his appetite is good, but he can not
stand up.
The statoscopc is registering air
barometer of great sensibiIty, con-
structed by NJ. Richard Freres. Being
far more sensitive than the ordinary
barometer, and giving besides a deli
cate curve of its rise aud fall traced on
paper marked with time intervals, it
is likely to be of great service in the
study of storms. 1t consists essential
ly of an air cistern or reservoir, COM
municating with 4 manometer, or
pressure recorder, which, by means of
a fine pencil. draws the curve of press
ure on the graduated scale of revoly-
ing barrel
