Prof Kohn, German botanist, has
recently discovered that spontaneous
combustion of hay and other vegetable
substances, is due to the action OF a
germ, aspergiJt,ts .ftiRaigdtus.

preventive of snow blindness or the in

1t is not generally known that there
are more wagons manufactured in s.
Louis than in any other city of the
country. The entire South and South
west are supplied with wagons of all
kinds from that point. In the line of
fancy wagons and carriages, St Louis
manufacturers beat the world, shipping
even to Europe and Australia.
MIR. Shelford Bidwell, in speaking
at the Royal Society's conversations in
London, exhibited an experiment which
may possibly explain the intense dark
ness, often accompanied by lurid yellow
glow, during thunderstorms. After
showing on screen the shadow OF
small steam jet, which was of neutral
gray tint, and OF feeble intensity, he
electrified the jet, and the shadow be-
came dense and OF peculiar orange
brown hue.
in aniline dyes Prof. Stilling, of
Strasburg, believes he has discovered
antiseptics strong enough to kill bac-
terra in concentration not injurious to
the human body, and at the same time
diffusive enough to spread over a
wounded surface. In man of seventy,
whose left leg between the ankle and
the knee was covered with ulcers which
would not heal, the suppurative micro
organisms were all destroyed in few
days. and the ulcers disappeared.-Ar-

In a recent lecture on Marine and
Fresh Water Fishes" noted scientist
said that fish have the power of infiu-
encing one another by sounds and
action. He had observed shoal of carr
following the lead of single one,
which conducted them to quantity Of
food at considerable distance away,
He had also noticed that certain frest
water fish, such as trout, were subservt
ent to a ruler, which might be seer
swimming at the head of his tribe. The
same was possibly the case with some
marine forms, like the herring and bass
An extraordinary report comes from
Fort Chippeweyan that the United
States surveyors have established tht
141st meridian, which forms the bound
ary between Alaska and Canada, twenty
eight miles farther east than it was sup
posed to be. If this is true, large arei
of gold placer ground would be trans
ferred to the United States. But
seems strange that so great an erro
should have been allowed to pass in
region which was we'll known to trader
and prospectors. rs.-Engineering and Min
