Prof. Rogers, OF England, has In

Immediately volatilized for the special
use Of ballOonists.
Mr.. Edison says that 5000 volts OF
electricity, alternating 500 times per
second, will kill man beyond power
Of resuscitation. Salt bandages on the
wrists will facilitate the process.
An important invention in railway
practice IS the method OF welding steel
rails by electricity, recently patented
by Baltimore electrician, by which
track-layers are enabled % lay con-

1t is stated upon medical authority
that readers should refrain from damp
ing their fingers in turning over the
leaves Of library books, as this is
sure way TO attract any stray bacilli

Prof. w. Ramsay suggests that

Mr.. Kergoyatz, chemist OF Brcst,
electrotypes bodies after death. By his
process the body is encased in "A skin

this may again be plated with gold, or
silver, according TO the taste or wealth

The manufacture OF counterfeit i'm
plements Of the stone age seems 10 be
becoming quite an industry. a recent

An instrument called the eostcD'Ome
has been invented as an Improvement
over the tedious and clumsy surgical
methods Of cutting through bones by
means Of saws and chisels. 1t is prac-
tically circular saw revolvcd ut very
high speed by an electric motor. An
ingeniously devised shield, which
passes around the bone TO be operated
upon, protects the surrounding flesh
from injury.

organic chemical compound, which is

French chemists now obtain from
the essence of birch bark, by rectiica-
tion, an essential oil which possesses
among other properties that Of being

A medical journal states that new
experiments have changed old theories
upon the best methods of treating frost
bites. A physician froze sixty dogs
into n condition Of completely sus-

were treated by the usual method of
gradual resusnita'ion In cold room,
