The mode M common use ef prulsciha
galvanic action is 10 fmmcrsc the plates IA
a trough with separate disIsions--st onA

excess. This end Of the trough or Bate
~ is called tie positive, and tic other end
the negative pole Of tho battery. Now, IA
. wire attached to one end il brought neer
to wire proceeding from the oth,r end,
the electricity passes ff,m the positive to
g the negative pole, and Spark l. seen,
like that proceeding from The commonxlcc-
tricsl machine, which is the electricity
seeking to establish an cquilibricm. Ii
the two wires arc kept III contract, there
is sfrcam of electric fluid passing iroua
one to the other, which is kept up by no
action Of the acid on the metallic plates al
ready mentioned. New, the ordinary
length tf these wires, in a common Gal-s
yanic battery, is but a few feet; but they
may he y thousand, or an hundrrd thuu-
sa, a, miles In lcl 9Th, and thc effect al

When the connection Is Interrupted lie
iron ceases to be magnetic, and is like shy
other piece Of soft iron. This maenei,
which the Professor has the power 10 Gre

is brass lever, with piece Of iron IT.

quarter OF an inch or less, or the horse
shoe. As soon as this last is made =
magnet by uniting the ends oftl,c wire Ut
Washington, it attracts the iron on tie L.
yer and draws one end Of the lever down
causing, at tie same time, the opposite end
to rise. Atthis opposite end is the pen or
stylus, which is Of steel about ali iuch long,
and about the size Of a knitting needle
Immediately over il, is brass. cylinder
with groove around il, into Which thc
stylus strikes when the magnet attracts ahe
other end Of the lever. Not far from this
roller are two others, revolving in con-
tract, like the rollers used 70 draw out cot
Ion prior to spinning il in a cotton mill,
motion Icing given to them " a sssy
simple clock work moved by d, weight
The Office Of these two rollers is 20 draw
I I'm another roller, and under the grooved
roller, strip Of paper which IS wound
round it like ribbon on its centre block.
With these explanations the oper&iion u
the machine can be readily understcoa.--
When the Professor in Washington wishes
to send message to Baltimore he spells i
with letters composed Of dots and lines
for instance. "A may be dot and line.
thus -; B two dots and line, thus
-; G a lins and d dot, thus -.
BY connecting the ends df the wires fcr
an instant only, a dot is made bS the ptes-
sure Of the stylus on the paper ,wkieh IS
passing over the groos ID cylinder; : Iine
is formed By letting the ends Of Tie wires
remain in contact for . longer time, when
the stylus is kept pressed on Tie moving
paper. The writing when completed 70

The mode Of connecting the Wires ~ re-
quired is very simple. One Of them is
