The g~alvanic battery which the -Agamemnon
has in use on board ant which is intended for
he station at Newfoundland, is hung in GIN
balls to prevent the motion OF the ship from
the dilute sulphuric acid over the par
titious between lis cells. Il consists Of forty
cells, containing a galvanic series of plates
.ine inches square, and composed alternately
of zinc ard plstinized silver. So great is the
power Of this battery, thata lump Cf iron placed
between its poles is Immediately burned up
The current here generated, however, must be
rendered electromagnetic before IL can be ap-
piled to telegraphie purposes. This Is accom-
plishsd by passing it through Induction e0ts OF
No. 20 guage, copper wire, insulated BY a silk
wrapping. By means Of machinery, this wire
IS wound with great regularity around hollow
cylinders Of soft iTen, five feet In length and
three inches in diameter, with a g~utta-pereha
sneating. Each LAYER Of wire is closely COW
cred with waXed paper to keep it separate frsm
the next succeeding one, until six miles OF II
are wound around each cylinder. This be-
comes the secondary coil; and its perfect IN
~sulation is finally secured by covering 1t close
w with gutts perchs. Over this Is laid another
coil. a mile and a-h1lf in length, Of larger cop
per wire. (NO. IA guage,) insulated like the
FORMER by wrapping it with silk. The eYlin-
ders thus prepared are brought together a. one
end Of each, by a bar Of iron, 30 as to make
them horseshoe magnets, and four such pairs
are united. The exterior coil Of wire is now
connected with the poles OF the battery, and al
one. becomes primarily excited. By this
means the soft iron cylinders are instantly con-
gerted into powerful temporary magnets
These. in turn, induce an Intense secOHddTg cur
rent in the smaller wire and it is this sscoHdG-
~ current which passes through the telegraphlc
cable. The operator works By a small key,
according to Professor Morse's plan ; and by
means Of an ingenious attachment, the motions
Of this key are constantly reversing the poles
OF the battery, thus sending through the cable
alternate currents Of positive and legative cleo
tricity /; in this manner, currents are constantly
discharged which would otherwise Tetsrd the
next succeeding electrical wave and make the
signals indistinct.
While DIR. Whitehouse and Professor Morse
were making a series of experiments on beard
he .4ganCmaOs, ten miles Of shore-end cable
we're received by the Niagara, and coiled on
her forecastle. The telegraph squadron, hav-
inc thus completed its preparations, sailed
from the Cove Of Cork on Monday afternoon,
August 3, and proceeded 10 Yalentia Bay, on
the western coast Of Ireland, in lat. 81 deg.
north. The peculiar necessities for the teTmi-
nus Of the telegraph are all admirably met at
this point. Yalentis presents a capacious and
accessible har0or. continuous, with a road
stead exposed to The sea, but presenting a bed
Of sand for lodging the shore end Of the cable
here no vessel could have occasion to anchor
when she could at once find shelter under Va
IeAtia Island. The Directors Of the Company
have decided to start from this point, and run
the cable across the Atlantic TO Newfoundland,
instead OF beginning at mid-Ocean, and sending
the ships east and west to the opposite shores.
This plan was adopted after grave and pro-
louged discussion Of the difficulties surround
ing both NODES Of procedure. The electricians
urged that a fixed (shore) station would con-
stantly afford them assurance Of continuity as
long az the cable w2s safe, and indicate when
% stop paying out in case it should be Tup-
ured. Also, that if only half of the cable
we're exposed at one time the rest would be
secured; but that If two ships, constantly in.
creasiug their distance at sea, were to be made
telegraph stations, either Of them might part
her cable without knowing which was in fault
and 90 continue paying out till both had wasteC
all they had aboard. On the other hand, tn
engineers argued that 1t was impossible Il
splice at mid-ocean with two tons Of CABLE
hanging from the end Of a blight and SOM
sailors objected that the change Of plan wouiC
occasion six days more exposure at sea, at 4
season already too far advanced. After all, i
vas decided to from the coast ol
ireland; aud, before leaving the Cove Of Cork
Cshtsin Hudson received tbs following com.
