The lecturer can bring it stored up to


the lecture table.
The .eronaut can carry it stored I'D in

screw can convey electricity in wheel.
barrow to the waters edge, place the
cases in whicllsit is stored in the bottom
Of his boat as ballast and turn his pro
peller with it. The lady can have it de.
livered at her door as the milk is and
work her sewing machine with it, The
tricyclist can put q case under his seat
and run by it. Lamps can be lighted
clocks lighted, clocks can be worked
and regulated, safes secured. spoons
plated, copperplates made by electricity
stored up in cases. Indeed, any opera.

accomplish otherwise, can now be done
by stored electricity.

and too gross in perception to be able to

crti'l as he is from merely mechanical
point OF view, his powers in regard to
minute are quite as marked, and, if pos
sible, more marvellous. The hand that

most delicate woman. It can catch up
and repeat along long conductor the
most minute vibrations caused by the
human voice reproducing them with
most perfect accuracy. It can prasn

If what has already been accomplished
in this now rapidly expanding region of
practical science iS SO wonderful, the fu-
ture prospect is still more SO. A few
more years may bring about state of
things in which men will be astonished
that they ever could have thought the
appliances of 1860 practical and conven-
lent, and the wonders of the steam en-
gine be to us as the loom of old days was
to those in whose generation the Jac.
guard was introduced. That the devel-
opment will be the more rapid and use
full in proportion to the general interest
taken in it by the public is sure; and it
is hoped that what has been said may
tend to promote such feeling of inter-
est in subject which is daily proving it.
self to possess substantial benefits for all.
