Sodium or zine-silicate, in hot enc
half or one per cent solution, is a new
French preservative and fireproofng for
wood, especially for mines.
Passing bubbles under ships by an
air Jet, or lubricating with kerosene oil
two or three times a day, has been
suggested as a means Of lessening fric-
ton.
The 'recognition-sense" Of ants is
found by a. Peiron to be a recognition
Of odor by the antenne. The usual
hostihties Of ants ceased when those
Of the stranger species or community
were given their own odor, while after
losing their antenn@ they fought friend
and woe alike.
During the last twenty years 2,061
balloon and air ship ascents have taken
place in Germany and only thirty-six
cases Of accident have befallen the
1870 persons taking part in them. Con-
seQuently one trip in ffty-seven comes
to grief, or one aeronaut in PIE meets
with an accident.
Sir Robert Ball, who has been lee
turing on the glacial epoch, informed
his hearers recently that the next ice
age is due 10000 winters hence. Then,
he says, all northern Europe and Amer
lea will be once more under an ice cap
that will cover the highest mountains
and last fer many thousands Of years.
In a novel device for preventing the
racing Of propellers, a pendulum gray
itates with the vessels motion. The
penduluM Is connected to the throttle
valve, and as the stern rises steam is
gradually shut of up to the point
where the engines are stopped alto
gether, the valve being reopened as the
propeller begins to take water again.
For the purpose Of studying the
causes Of mountain sickness, two
French medical n authorities, Drs.
Guillemarki and rMoog, during last July
made a stay at the Mont Blanc observ-
atory. According to the results Of their
investigations, which have now been
published, "the diminished tension Of
the oxygen of the atmosphere clogs the
process Of oxidation and this sets up an
elaboration Of toxic substances, the re.
tention Of which causes symptoms OF
naturalization"
/ A recent discussion Of the duration
of life among birds in the English peri
odical, knowledge, recalls the story Of
venerable parrot which Humboldt
saw during his travels in South Amer
lea, and which, although very voluble
could not be understood by anybody
because the words 1t used belonged tt
the language Of tribe Of Indians who
had become extinct since the aged bird
took its lessons. Parrots are proven
bially long-hved, and 80 are ravens
and some species Of vultures. A white
headed vulture died in the geological
gardens at Vienna after 11S years Of
captivity.
Recent experience with the acetylen,
blowpipe in England has approved Il
as q valuable invention. 1t produces
a temperature exceeding 1000 degrees
The temperature producible by the oxy
hydrogen blowpipe, 5000 degrees t
300 degrees, is limited by the dissocia
ton temperature Of steam, whereal
with acetylene the limit L. that Of tn
dissertation temperature Of carbon
monexid, which is much higher. Tn
acetylene, in a dissolved state. is use,
in conjunction with oxygen. 1t split
, M into its constituents, hydrogen an,
: carbon, at the base Of the fame, ant
the carbon emily takes part in the burn
ing. The hydrogen remains free an,
. forms protection to the small cone a
the nozzle, where the carbon is burn
ing, and which Is the point of maximum
temperature.
