The new quartz vessels. so valuable

changes, have disadvantages. They

gases were originally at about air pres

1t is we'll known that music is a val
liable curative agent in the treatment
of the insane, and a New York physi-
clan AYERS that the influence of music
is more powerful than any other. per-
haps than all others. iii benefiting his
patients. Some patients have been
known to gain weight, while the pulse
and respiration also improve. Music
has healing effect upon both the body
and the mind
The recent discovery that alloys not
containing iron can be made as mag
netic as iron has suggested the new
theory that magnetism depends upon
the grouping of the molecules. When
the special magnetic structure is made
better known, it is hoped to improve
upon electrical magnets by adapting

Eigorite, the new explosive of Pro-
fessOr Shulz and Engineer Gehre of
Switzerland, is a nitrous compound
which, united with saltpeter, has given
results claimed to indicate strength
| about ten times greater than that of
any other explosive In the open air it
burns without exploding. 1t has the
further advantage of being insensible
to friction shock of conclusion, while
1t is not injured by wetting or by

The new chemical automobile fire
engine Of Leicester, England, carries
large cylinder of carbonate of soda
solution, with bottle of sulphuric acid
| suspended over it, and travels thirty
miles an hour When the acid is tip
| ped into the soda water, carbonic acid
is rapidly generated, quickly giving a
| pressure of $50 pounds. This pressure
| forces the water in a four-ffths inch
| stream to Il height Of forty feet, and

A French writer in a scientific maya
zine tells of the great ocean depths Of
$4,000 to $4,000 feet, the temperature
tending toward zero, with perpetual
darkness reigning below depths Of
about 1,2S0 feet At that level plants
| deprived Of light. cannot exist, and
the animal life must be carnivorous.
The organs of sight, not being used,
have disappeared, and yet there is
| light even in that sightless world. A
| German exploring ship found a fish
with enormous eyes at depth or 6,400
| feet. PhOsphOrescence is common in
these hollows Of the sea; sometimes
| special organs flash light.
How electricity influences plant
growth has been easy to explain. 1t is
pointed out that the heat can havelittle
effect, as this cannot replace or even
greatly re-enforce the heat of sunshine.
The electricity acts rather as stimu-
lus to all the vital processes. Capil-
larry attraction of water is promoted by
a positive current flowing upward, and
as electric influence is beneficial only
with an abundance of water, the rise
of fluid is assumed to play a part. In
some exceptions a positive flow down
ward gives the best results. which is
thought to mean that more food is sup
piled by the leaves than is commonly
supposed.
Mr.. Matson. chief steward of
steamer of the New York and New
Haven Line. has invented lifeboat
which gives promise Of being useful.
This boat is u by by feet. is water
tight, with compartments for food and
fresh water. 1t rests upon the decks
on platform the latter being support
ed by uprights kept in proper position
by pins. By pulling the lever chain
the lever turns. the platform is tilted
and the raft glides into the water. At
It's first trial twenty-five men were low
cred into the raft by an automatic
pulley. ami in five minutes after reach
ing the water the raft left the side of
