In a paper recently read before the
American Philosophical Society," r.
Meade Bache announced that from ex-
periments by himself and others he is
led to believe that electricity may soon
be applied to the publication of water.
The exact method by which this result is
to be accomplished is not diyulged, but
it will consist of such an operation upon
the predatory bacteria as will destroy
the dangers now prevalent in the drink
ing water they befoul. Every consider
alton of good health adds emphasis to
the hope that Mr.. Bache is not deluded
prophet. Electricity will score its grand
est triumph if it eliminates the perils that
Turk in contaminated water.
