THE PACIFIC.

The Commander-in-Chief, Rear-Admiral Moresby,
C. 8., shifted his flag from the Portland, 50, Captain

Thetis, 38, Captain Kuper, C.B. It was expected that
the flag-ship would return in April.

THE YELLOW FEVER AND.HER MAJESTY'S
SHIP DAUNTLESS.
The following letter has been addressed by one of
the two or three surviving officers of the fever-stricken
screw-frigate Dauntless, to a relative in England :

" H.M.S. Dauntless, Barbadoes, Jan. 13.
"I am delighted to be in a state to be able to write to you
as usual. I can assure you that there was a time when your
chance of ever hearing from me again was small indeed.
I am happy to tell you that the terrible cloud of pesti-
lence that has now for nearly two months, hung like
a black pall over this unfortunate ship, I think is on the
point of being dispersed—at all events there is a ray of
hope, seeing that we have not had a case of fever for six
days from the ship, nor a case from the camp for five
days.

" A considerable part of the stores, &c., have now
been removed to the shore, fumigation extensively used,
and other means of purification, and their combined good
effects, I think, now are beginning to tell. The Devas-
tation arrived here on the 6th, for the purpose of towing
us over to Antigua, but it would have been folly to have
bundled men and stores overboard at a time—the turning
point of (apparently) from sickness to health ; therefore,
the Devastation returned to the, admiral, who would
meet her at Port Royal. If matters progress favourably
for another week, we shall be getting stores, &c., on board,
and will leave here for Berm i t•-la, the only direction where
health can be found under ou.. broken-up and debilitated
condition. Our present chapiai4 goes home by this
mail; invalided from effects of yell fever. As regards
myself, lam now nearly recovered. Have heard nothing
from.the Highflyer, but I believe she is now at Port Royal
with yellow fever. I suppose you have already heard
of the death of the marine officer of the Calypso (Lock) ;
it is reported that he dined on board the Highflyer, and
on his return to his own ship fell sick of the fever and
died.

" I dare say we shall be paid off directly we arrive iY
England, which will most likely be about the latter end
of April,in a fi

It may, perhaps, be, recollected that the General

lay, Field, and Co.'s), as to the propriety of decreasing

the width of the fan, and the ;result was the construc-
tion of a new screw of about four feet greater pith, with
much less breadth. After the:, ship had been fitted, she
proceeded down to Stokes Bay and the following is the
result of the trials : •

Thus giving a mean result of speed of 10.353 knot:,

easy. '

The highest mean rate of speed ever attained by the
Queen of the South with her original screw was 9 knots ;
revolutions, 62 ; and the above statement shows that by
the new screw the same speed is accomplished under 52
revolutions which was obtained with 62 revolutions by
the old screw, and the weight of the screw is not only
reduced by 16 cwt., but the screw can now be raised in

ENTERTAINMENT AT THE MANSION-HOUSE.—The
Lord Mayor, on Tuesday, entertained his brethren, the
aldermen, their ladies, and a-numerous party, at dinner
'at the Mansion-house. In the ovening the Lady Mayor-
ess received a large assembly, and dancing was kept up
with great spirit to a late hour. The band of the Cold-
stream Guards were in attendance, and played various
airs during dinner ,and al4i supplied the music for the
dancing with their usual talent and success. The fog,
however, which was exceedingly dense at the west end
of the town, prevented many of the intended guests from
being prevent both at the dinner and the evening recep-
-1 tion, some of them having wandered about in their car-
riages with flambeaux fora long time, and found it im-
possible to reach the Mansion-house, were glad to regaintheir homes, and escape the danger and confusion oethe
treets.
