SCIENTIFIC AND INDUSTRIAL

A fund of 81, 900, 600 has been left by
an English brewer for advancing econo.
omic and sanitary science.
A Frenchman has invented key
which simplifies and renders lasting the
tuning of stringed instruments.
A petroleum motor that will make fif-
teen miles an hour and cost 81 per day
to run is being tested IN Chicago.
The watch manufacturers all over the
United States are crowded with work,
and competition is narrowing margins.
Psychologists have established the fact
that the masculine heart weights more
and is larger than that possessed by the
fair sex.
The Popular Science Monthly says that
no flying machine which will fly can ever
be constructed until gravity Is turned
wrong side up.
A document enclosed in a bottle was
dropped in the sea in March, 1886, by
the Prince of Monaco, to test the cur
rents. 1t has just been washed ashore
at Orkney.
An envelope has been invented which
is tinted in such manner as to turn
black, blue and red if an attempt is made
TO open it by wetting or exposing to
steam. Damp weather does not affectit.
At Bendigo, in the colony of Victoria,
New South Wales, gold is now being
procured at a depth of 2400 feet from
the surface. This is the greatest depth to
which the gold seekers of the antipodes
have so far penetrated.
Corn is the source Of nearly all the
starch consumed in the United States.
In other countries starch is made from
potatoes, wheat, rice and a variety of
other materials. Maine produces great
deal of starch from potatoes.
An electric current observed on o tele-
phone line running from Bridgewater,
Nova Scotia, to the mines thirty miles
away, is supposed to be produced by
"natural battery" formed by deposits
of copper, silver, lead and iron ore in the
vicinity of the gold mine.
The interesting aud important dis
covery has beer made that the filaments
of incandescent lamps soon break when
used near moving belts or other sources
of frictional electricity. The life of
such lamps may be greatly increased by
covering them with wire netting con
nected with the earth.
Experiments by NJ. G. Cow indicate
that ordinary sunlight does not give us
the true colors of bodies. These can
only be shown by light combining all
the visible colored rays, and giving a
complete continuous spectrum. The
spectrum of sunlight is interrupted by
bright and dark bands.
Concerning the habit of coughing in
church, the London Lancet says: at
represents to a large extent avoidable
evils, bred OF habit and thoughtless
imitation, and their very desirable re
ductlon is therefore by no means hope
less. Even where q basis of disease
underlies the explosion little self-con-
troll could usually do something to lessen
its force or its frequency"
A Swedish scientist claims to have
discovered the secret of petritying wood
by artificial process. He thinks it will
be possible ere long to construct ediices
of wood and convert them into stone
As it takes three months and costs about
$25 to petrify block of wood of the
dimensions of one cubic inch, it Will
probably be some time before his process
will be generally adopted.
Old as is the theory that trees promote
regularity and plentitude of rainfall, and
generally accepted as though an axiom
in natural philosophy, it is being vigor-
ously attacked, says the Sanitary Neos.
The trouble has been that only facts
favorable to this hypothesis have been
available. Now the result of impartial
investigation seems to show that cause
and effect have been badly mixed.
