Mr. W. Thompson, Professor of Natural Philosophy,
Glasgow College.
These are all the documents that have been re-
ceived up to this morning, in pursuance of the care-
ful investigations which the directors are engaged
in making into every appliance fur insuring, as far
as forestht can enable them, a completely success-

vast number of suggestions as to future proceedings
are daily received, which are all undergoing careful
examination by independent persons capable of
judging as to their merits.
I have much pleasure in adding to the above-
named reports a copy of a very gratifying letter, re-
ceived by the directors this morning, from the com-
manders of the American .hips engaged in this
service, which will show that; although a present
check to operations has temporarily postponed the
successful laying of the cable, yet, at all events, the
first fruits of the great work have already appeared
in the form of an extension of mutual respect and
kindly feeling between the two nations engaged in
its accomplishment.
I am, Sir, yours truly,
GEORGE SIMARD, Secretary.

" Gentlemen,—We, the undersigned commanding eefle
cell of the several ships composing the Atlantic Telegraph
have great pleasure in expressing our opinions with re-
ference to the Atlantic Telegraph.
" We are of opinion, drawn from our several observa-
tions and experience, that no obstacles of a nautical or
physical character exist in the way of the enterprise, and
that the Efficiency of the form of cable adopted by the
company is in every way adapted to its mission.
" With regard to the machinery, we are of opinioa
that the form of controlling power adopted and the
mode of lubricating and adjusting the breaks admit of
very great improvement.
" We ay* thoroughly convinced from the soundings
made by Lieut. Berryman, United States Navy, on the
plateau bet ween Newfoundland and Ireland, subsequently
confirmed by Lieut. Dayman, Royal Navy, and the in-
vestigations of Lieut. Maury, Thited States Observatory,
and from our own nautical experience, that no under or
surface current cal.ts between these points to interfere
with the successful laying of your cable,
" We all epee in thinking that no form of submarite
telegraph cable could be devised more suitable in every
respect to the object intended to bo accomplished ; that
its lightness, toughnese, and flexibilitadapt it in every
and Ireland, and we are unwilling to recommend its mo-
dification or alteration in any way. We are also of opi-
way for the purpose of being laid between Newfoundland
nion that no natural obstacles exist to prevent its being
euecessfull leid between those points, and our views as
to the future prospf ets of your enterprise are sanguine.
—We have the honour to be gentlemen, yours faithfully,

"Gentlemen,--We, the undersigned, who have been
engaged as engineers during the construction, shipment,
and submersion of the Atlantic call?, beg to submit to
you our judgment as to its fitness for the object for which
it was intended, in regard to material, dimensions, and

structure.
" We consider it to be so eminently suited for laying
in deep water that we cannot suggest any improvement
in its ferns and construction, and do not recommend that
any charge whatever should be made in the manufacture
of any future cable for crossing the Atlantic.

iron wire, instead of single wires, as in former cables,

"The conducting wire being also formed of a strand
of seven copper wires, the chance of continuity being lost

bability of any flaw or weakness occurring in more than
one of the seven wires at the same place.
