The revolution of a magnetic needle indicated GER
tain characters upon paper, formed certain char
acters by combination Of certain signs.
"ln connexlon with this apparatus there was usu-
ally signal, and frame which carried the paper
for the types; by which means the whole contri-
vance was naturally very much complicated.
"Ihe principle upon which the electromagnetic or
American telegraph is based, is this; piece Of iron
may be rendered magnetic at will, by means Of a
magnetic stream, so that an apparatus to which a
pen is attached, may be governed, and marks inn
printed upon strip ofpaper kept continually in mo-
ton, which serve as types for a correspondence.
This very simple apparatus serves at the same time,
for signal, and requires only single wire and a
very weak galvanc battery, or a magneto-electric
motive power.
"The application of electromagnetic to tele-
graph, was proposed by Professor Morse in 1882,
and thereafter putin executionat least several
months earlier than the system of Gauss and Weber
was made known. He therefore was entitled, be-
yond dispute, to the honor of being the first who
made the first direct application Of eecro-magnetsm
to elegraphs which is abundantly proven by certif-
Gates shown at that very time, which are entitled to
full confidence.
"For several years Professor Morse conducted a
set ofexperments in Paris before the various scien-
tifc institutions, and received the large medal of
honor, as proof of the importance and value Of his
discovery.
"The practical difficulty of extending the electro
magnetic chain to great distances is well known to
all who have turned their attention to this part of
science and has been regarded by many as insuper-
! able. This difficulty has been overcome by Pro-
lessor Morse, through simple though very talented
continuance; and in it consists one of the most inn
portant parts of his telegraphie system. This por-
ton of the invention it is not yet proper for
which will be readily understood, to make known
| to the public.
at however is no longer matter of doubt that
Professor Morse has furnished the world with the
most complete, and yet most simple of teegraphs;
one which, In the present progress of science now
more closely allied to practice than ever in all mat
tiers of civilization and commerce. promises the most
useful results.
"In order to the right of priority for himself
and his country, and to make the system better
known also in Europe, he sends an agent to the
principal countries of that continent with complete
apparatus, which will enable him to lay open to the
judgment of the different governments and scientific
societies the results he has obtained.
"He has secured for this purpose as mentioned
above, the services Of one of our worthy fellow
landsmen, Mr.. Fleischmann, who has been employ.
ed for several years in the Patent Office as an en-
gineer Being furnished with distinguished letters
of recommendation, this gentleman has undertaken
tour Of Europe, in order to furnish this govern
ment with late information upon the progress of the
mechanic arts in Europe, and Germany in particu-
lar, and of the condition Of agricultural science"
