from the Baltimore Patiiot.1
Morse's Electro Magnetic Telegraph,

variety OF statements in reference to the pecu-
iar construction and modns operandi OF this won.
derful and admirable machine, now In successful
operation between Baltimore and Washington,
have been published in various journals through
out the United States. Many of these descriptions
conveyed blu, a partial and inaccurate idea OF the
Telegraph as IL really is, and some OF them have
led to positive error. That the curious and scien-
tlhc may have a just conception OF this admirable
and astounding triumph of art, we have collected
facts from sources alone to be relied on, and pre-
pared the follow ing statement -
The generator Of the galvanc fluid, consists OF
so glass tumbers OF the size in common use, IN
each of which is zinc hollow cylinder reaching
from the top to the bottom of the glass; and almost
filing 1t up. From the top Of the zinc cylinder
projects an horizontal arm of the same metal, tx
tending two inches beyond, to which is soldered
platinum foil, 81 inches long and halt an inch wide,
and hangs vertically from the end OF the arm In
the hollow of the zinc cylinder is placed a small
porous cup inches long and ! inch in diameter.
The glass lumber is then filled with dilute sulphur
acid, and then the small cup filled with pure nj.
trio acid Being thus prepared. the platinum OF
one glass is put INTO the small porous cup OF the
other, and 30 through the whole SERIES The
last glass ut one end of the row has It's platinum
:odered to strip Of copper which terminates IN n.
glasses stand At the other end, the projecting arm
has also copper strip sodered to it, and terminates
in a cup OF mercury In the same manner as the
other end. These two ends constitute the negative
and positive poles OF the battery, which is Wash
ington.
From one Of these cups of mercury proceeds a
copper wire, of the size OF common bell wire, ex.
tending to Baltimore, upon poles 70 feet high and
225 feet apart. Here it enters the Telegraph office
and passes around first one prong OF bar OF iron,
bent in the form OF horse shoe, and from that
around the other prong, and then the wire returns
10 Washington upon the same poles as the other.
At Washington the return wire is soldered to a
slim fiattened slip OF brass, the one end OF which
is fastened upon pedestal and the other end, with
an ivory button upon IT,, stands over a brass plate
To the under side of the brass plate is soldered
wire, which extends to the other pole OF the bat
terry. The battery being now leady for action, you
have but to place your finger upon the key and
press it until it touches the brass plate below, and
instantly the galvanic hud flies its 81 miles. Take
off the pressure of your finger, and instantly the
fluid has ceased to flow,
We have alluded to the bar Of iron bent in the
form of horse shoe at Baltimore, around which
the main wires are colled 1t is perhaps not gene
rally known that If bar OF colt iron Is encrcled
with copper wire wound with some insulating sub.
stance like bonnet wire, and a current OF galvanic
fluid passed through the wires thus surrounding the
iron, it becomes instantly a magnet. II the
current is made to cease, that instant the
magnetism OF the iron is gone. II over the ends
OF the two prongs of the bar OF iron, where IT pro-
Jects beyond the coils OF wire around 1t, small
tatened straight bar of similar soft iron is placed,
being hung upon one end OF lever, and the lever
supported delcateiy upon plvots 30 as to rise and
fa-it is clear that whenever the bent iron is made
magnet, the iron directly over It, upon the lever,
will be attracted down with considerable force.
The lever recedes when the magnetism Is destroyed
by means Of spring. On the other end OF this
lever are three steel points pointing upwards, and
directly over them is steel roller with grooves
turned in it, corresponding to the three points,
that when they strike the roller by The power OF
the magnet, each Of them fall into its own groove
Between the three points and the steel roller, the
paper passes, at uniform rate, being drawn along
by two rollers, connected with the clock work,
which is driven by weight. The paper is in rolls
IA inches in diameter and IL inches wide, forming
a. ribbon Of a continuous length. This roll il
placed upon spool which turns easily upon its axis
in front Of the pen, the paper is drawn off by the
movement Of the clock work. The alphabet is as
follows:-
