The Eiffel Tower in Paris is found to
be remarkably valuable us meteorologi-
cal observatory.
The rate of increase of temperature in
descending mines and borcholes is one
degree Fahrenheit for every sixty-five
feet.
N. Lichtwitz, French savant, has
suggested the use of the new Edison
monograph by aurists to test the hear
ing powers of their patients.
Hydraulic power ut pressure of $50
pounds to the square inch is now con-
vcycd about beneath the streets of Lon
Con as steam is conveyed in this country.
A new phonograph, simpliicd from
Edison's model, by painter named Eos
satl, is mentioned i'll the 6Iilan papers.
1t is described as simple apparatus,
taking up little room, and costing less
than $50.
A purity of scientists have recently
made an ascent of Mt OriM,ba, from
Chalchicomla, Mexico. Mrometric
measurements show the height of the vol
cano rs 10, 200 feet, about 300 feet less
than was supposed.
DIR. Cumberland, Pastcur's assistant
III Paris, has just made discovery of
vital importance. II is that tine essence

OF typhoid fever patient kills the bac-
terra within twelve hours and prevents
the disease from spreading.
NJ. Gucroult proposes to Introduce
small apparatus that will represent the
face and gestures of Il person speaking
through Edison's improved phonograph.
While the phonograph cylinder is turn
ing to register the speech, instantaneous
photographs of the speaker will be taken
at the rate of 900 per minute
There are IS, $50, 552, 900 living crea-
lures in gill OF milk taken from the
COW in the evening and allowed to re-
main over night ut the moderate tenn
pcraturc of seventy seven degrees F.
Indeed, in such gill of milk there are
more than twenty times us many in
habitants us there are human beings on
the earth.
Frederick Beer, the Austrian sculptor,
has discovered n process for making
marble fluid and moulding it as bronze
is nodded. The new process, called
bcryt, is cheap and we'll adapted to or
namentation of houses and the construc-
ton of floors, baths and small pillars.
y stock company has been formed in
Paris to place it on the market
A French machinist has just invented
Il new lubricant called dynaminc, and it
is being introduced in France 1t has
the consistency of butter, which it also
resembles in color, aud it does not in
iancat n temperature lower than about
42O degrees, its melting point being 1873
degrees. 1t is free from resinous matter
aud drying oils, is not acid aud has 10
chemical action on metals.
A recent Mexican invention consists of
IN electrical device for dcep-sea sound
ings and raising an alarm on shipboard
when nearing sholl water The appar-
atus comprises Il metal cylinder with
wood lined base, and Il chamber for the
reception of n central socket containing
an inside tube about half filled with
mercury, with the necessary insulators
and conductors, discs, batteries. and
electric bells. When the vessel APP
proaches reef, or comes into shoal
waters, electrical communication is cs-
tablishcd between the discs and an alarm
sounded on the vessel.
A striking example Of degeneration in
growth is exhibited by the scale that at
tacks greenhouse and other plants. Ac-
corling to Mr.. Bernard Thomas, in
Science Gossip, it is IL dcgeneratcd fc-
male which lives upon the sap of the
plant, continuing TO Increase in size and
rcproduca its young. These may be
found underneath it as minute red
bodies, just visible to the naked eye, and
mt this time Of their life comparatively
active creatures; but they soon settle
down and begin to degenerate. Their
eyes become indistinct, and finllly,
with their antcnnr and lcgs, shrivcl
away, the body loses its thickness, and
they appear as il without life.
