In q minute the sowest sound your

A Frenchman claims to have invented
thermometer so sensitive that its in
dex needle will defect two inches upon
the entrance of a person into the room

The remarkable finish of American
papers is impaired by the addition of q
mineral called ''agalith," silicate of
magnesia somewat resembling asbestos

A triumph in electric lighting was
achieved recently in Vienna, when, dur

than 5000 17-candle power lamps were
burning for more than four hours with
out flicker from irst to last.
Natural gas is reported to have been
discovered at Pete sborough. England.
| The clay there when subjected to heat in
close vessel yielded dense smoke,
which when lighted, burned. like coal
gas for a considerable time.
A Mr.. Myer has just patented, in Ger
many, a composition for removing old

The giant of all guns is in process of

A scientist who has plenty of spare
time on his hands declares that cubic
inch of air in a room contains 80, 31S, 600
particles of dust, and they contain all
kinds of deadly things, which injure the
lungs and other delicate portions of the
interior department. This shows how
/ great risk man runs when he INDUCES
in the prevalent fashion of breathing. 1t
has got to be, according to scientists,
about as much as a mans life is worth to
