MORSE'S ELECTRO-M MAGNETIC TEI.E-


The complete success which has attended ti.
working Of his Telegraph, now in operation betwees
Washington and Baltimore, has attracted public at
'ention 10 H. even En this busting city, and led 10
many inquiries as To the method by which such won
deriul results are achieved 1t was fortunate both
for The inventor and the invention that the commtni
cation was completed between Washington and Raj
timore prior TO the meeting of the Democratic Ia
tional Convention, (thc proceedings of which were
awaited with so much interest because an opportu-
! nifty was thereby afforded to test the praotjcabiry
ana usefulness oil the invention, in eseost efectua
manner by means of this Telegraph every new
movement oil the Convention was made known at
Washington almost simultaneously with It's occur
renee while with the same rapidly The proceeding,
OF Congress were made known at Baltimore The

along last night with the intelligence up 10 O'Clock
which had been received here by the lightning ex-
press two hours and a half previously

Were tins Telegraph extended from Portland TO New
Orleans intelligence could be transmitted the whole
distance IN space Of time short is required 10
transmit IT from Washington to Baltimore; or At

easy TO see that such Telegraph would be Of great
Importance in case of war. II a hostile fleet should
make It's appearance off Portland the fact could be
mace known at New Orleans, o al any intermediate
station, IN three minutes. Moreover this Telegram

al every station the process must be repeated Not
SO with Morse's Telegraph Surprising the commu-
nicnuon 10 be complete, single touch Of the wire
would send the Intelligence around the globe Al
least tins probable; for Professor Morse. oxpcri

dlmlnshes for the first ten miles there is no pereSp

The experiment has been extended viz "a miles -
From the 10Th TO the 33d mile inclusive the WEIGHT

Ana Inc presumption Is, the same law holds good Tor
any greater distance The scientific facts on VII CHI
Professor Morses invention resls are thus stated Il,

second That magnetism is produced in a niece of
