A NEW MAGNETIC TELEGRAPH.

Mr. Balm, an English gentleman, has re.
Gently brought to this city Magnetic Tel
egra phi, of which he claims the invention,
and which differs in some important respects
from any now in use. We are not, Of course,
prepared 10 state, from the slight cxamina-
lion which is all we have been able to give
i. 1.-The precise extent nor the grounds OF his
claim. But in that part of the invention
which relates to the actual transmission of
intelligence between distant points it cer-
tainly possesses one feature at once original
and superior to any we have hitherto seen.
In Morse's Telegraph the operator at one
extremity of the line IS obliged (n cffecD to
write each letter of the communication.
Dots differently combined represent differ
ent letters, and he must make in succession
the combinations of dots standing for the
letters which spell the words he wishes to
send. Each letter as he makes it is reprodu,
ced at the other end. In this way commu-
nications can be sent over one line as fast,
and only as fast as one can make these combi.
nations-whch is not quite as fast person
can write.
Mr.. Balm resorts to a different method.
In his system also combinations Of dots rep
resent letters. cfore sending the message
he writes it in telcgrapic characters upon
narrow slip Of paper, not with ink, but in
perforalions. The dots forming the letters
are cut through the paper. The instrument
for doing this is very simple, and twenty
persons, if necessary, can work al different
instruments upon the same communication.
When the message has been thus written in
perforated telcgraphic characters, it is
wound round a metallic cylinder, and upon
the paper, thus wound, rests delicate me-
talIic style or rod. Now the cylinder and
the rod are connected with the two poles of
The battery. While paper, which is a non
conductor, is between them, there is no
connection; but when the rod falls upon The
cylinder the connection is established; and
the electric current is transmitted through
out the line. At the other extremity is
a cylinder covered with paper, with style
ur rod resting upon it, and prepared chem
ically, so that whenever the electric current
passes through it, the paper takes mark;
when there is no current it takes no mark.
" hen the machine is put in operation, The
cylinder on which is wound the paper con-
tanning the perforated message is put in rev.
oluton. The metallic cylinder, and thus es-
tabshes current whenever ii comes TO the
petforations. Consequently the chemically
prepared paper at the other end contains
marks corresponding exactly with these
pcrlorations. In other words, the message
is geographically written at the other end.
And this Can of course be done much more
rapidly than person can write. Indeed,
one thousand letters can be thus transmitted
per minute, and there is no reason why even
this should limit lis operations.
The difference between Morses Telegraph
and Bain's, in the rapidity of their operation,
may be thus illustrated. Suppose the Pres.
dcnl's Message is to be sent from Washing
tonic New York. In Morse's Telegraph one
man at Washington mus, form each letter of
the whole in sncccssion; and it will be re-
ccvcd here, therefore, no faster than he can
do lhis-which is at the rate Of about $50
letters per minute. In Bain's Telegraph, 10,
20 or 50 persons could take the message,
divide it into as many orlons, and each be-
ing furnished with the proper instrument,
could write, in perforations, his portion up
on the strip of paper. This paper, wound
upon lhe cylinder. and the machine put in
operation, tie Message would be transmit
ted at much more rapid rate than by the
other mode.
This description, five have succeeded in
making it all Ineligible indicates one point
IN which Ban's Telegraph appears decided
Iy superior TO Morse's. 1t differs from that
also in other respects, concerning which we
cannot speak with accuracy. 1t is in use be-
tween London and Birmingham, l l2 miles,
and between Manchester and Liverpool, 80
miles, and on both these lines, we are told
it gives perfect satisfaction. We understand
IT IS Mr.. Bain's intention, if possible, TO cs-
tablish line between this city and Boston.
The patent has Of course already been Sc
cured, both in England and in this country.
While competition in telcgraphic commu-
nca,ion, as in every thing else, is of service
10 the public, we trust that Professor Morsc's
legal rights to his invention will be not only
secured bu, respected. This is due not only
to him, but to common Justice. His name
ought not 10 be added to tho long and sad
list Of inventors and bencfactors of their age
who have been compelled to look to future
times for their reward. We make this re-
mark with no special application, at least of
all to that under immediate consideration.
