net be transmitted from Ireland to Newfoundland.
II the copper ropc had been completely broken
across and the ends separated from contact no sig
na!s could have been sent either way But if there
existed leakage of electricity near one of the sta
uons, or diminution in the conductibility of the
WiTe by Its attenuation or other cause a sig
nal might be received at that station, though it
could not be transmitted from it,
The intensity OF Il current of electricity sent
through any length Of electric wire or cable is di-
mnishea IN some ratio, depending upon the length
olthe wire through which it passes. The current,
winch may be OF great intensity as it leaves New
ioundland, becomes much weaker as it reaches Ire
land. As it leaves Newfoundland If wouId nerhans
paraliyze you; as it nears Ireland YOU mirht take
1t with lmpunIty. Now, if there be an interruption
or leakage, not total stOppage of the electrical
current near Ireland, the current sent from Now
foundland to ireland might suffer great dminution
Of intensity near its destination and vet be stronr
enough to make itself manifest to the recordin in
strUment in Ireland On the other hand the cur-
great loss of intensity near its starting point
might not. after its dminuton of intensity, be able
to record its presence at Newfoundland.
The deep and intense interest which all must feel
IN the present interruption of communication be-
tween the Old and New World must be our apology
Tor endeayoring to pOpuarise an abstrusc point OF
science The letter OF Mr.. Whitehousc is more sat
lsiactory IN one respec-it makes us hope that the
cause of the interruption may be from some injury
to the shore end OF the cable, either near Ireland
or Newfoundland.
We cannot enter into the disscnsions between
Mr. Wmtehouse and the directors of the Atlantic
Ie'"Graph Company so long as only one side of the
90 son Is presented to the public All personal
diScaAd and difference becomes insirnifcant when
compared with the great question now at stake
There are numerous causes which may have pro-
duced the interruption Of electrical cOmmunica.
ton. single hole through the putta percha or
Insulating covering Of the copper wire, no larger
than suiHcient to allow single hair of the head to
pass anywhere between the wire and the outer
casing oi non or the water occurring at any point
OF the whole length of two thousand miles of cable
would produce the fatal result
1t must also be borne in mind that the mvsteri-
Gus interruption for some minutes of communca-
tion between the Agamcmnon and the Niagara, af-
ter the faulty piece OF rope had been repaired,
which afterwards mvsterousv disappeared, has
never been accounted for. The raising the temper
ature Of any portion Of the gutta pcrcha sheath
from tortytWO degrees to sixty or seventy degrees
might be productive of serious interruption OF
the electric current. In addition to all this, we
have the extraordinary pranks of terrestrial magnet
ism. The history Of the preliminary proceedings
OF the Atlantic telegraph, published last year by
the directors OF the company, contains the follow
ing instructive passage:-
1t is within the bounds of possibility that the per-
turbng influence Of terrestrial magnetism, especial
ly during the occurrence of magnetic storms, may
prove to 4 certain extent troublesome 1t is so even
on shorter circuits The superintendent of the
magnetic and meteorological department of the
hONal observatory at tTrcenWlch, Mr. GlalSher, not
unrequentiy finds indications Of the coincidence OF
such magnetic disturbance with failure in the ser
vice Of certain lines Of electric telegraph. lie tells
OF the editor of provincial newspaper who sus-
pected the officials of 4 telegraph of being in league
against him to withhold certain information which
he required when the Greenwich self-registering in
strumcntS were recording on their paper perfect
tornado of magnetic oscillations, looking on their
linear and tabulated sketch like wOndrous Al
pine land Of Jagged peaks and abrupt valleys.
Whatnvar y la tbn nat tur Of thn in.
terruption whether temporary or permanent, we
must remember that the great probem-against the
possibility Of which many chances Of failure
seemed arravcd-Of the possibility of electrical
conn. .unication between the Old World and the New
has been satisfactorily solved.
DISPATCH FROM THE AMERICAN END 0FTHE

In addition to the above, are permitted tc
state that the New \ Iork honorary directors of the
Atlantic Company Yesterday received a dispatch
from the Superintendent in Newfoundland, who
states that the electricians have been unable to com
municatc with the Nalentia station since the lst o
September, but the electrical manifestations art
such that doubt exists here that the difficulty il
