storage Of electricity. Certainly may collect elec.

Professor Barker exhibited the Faure battery and
explained that while not differing IN principle from
that of Plant6 its superiority consisted IN the prep
aration of tine plates so that they would OxyAze
much more rapidly Uhis being ACCOMPLISHED
by covering them with red Lead. While II would
take three months TO change Plant6 battery
hOura just b fore concluding, Professor Barker
exhibited piece of stout wire bent into hooks
at the end and tipped with brass balls. 1t was
a specimen OF the apparatus OF
the University Of Pennsylvania. he SAID
and then explained that 1t brdged
over a century and quarter aud connected the ex-
pcriments OF Benjamin Franklin in l7i9, with
those he had just exhibited 10 1883
IL was. IN fact, portion OF Frankns
apparatus. which had come into the pos
session Of the University Of PENNSYLVANIA.
Professor Barker added that he had attempted to
make PLAIN the grin .ipIes on which the storage of
energy was possible. 1t was not only posi-
bic bat feasible. bat there of necessity loss
in the charging, and the same quantity Of current
could not be got out that was put IN.
