RUSSIA.

We have received the St. Petersburg journals,
of the Ist and 2d inst.
The first mention of the illness of the late Em-
peror is made in the Journal de St. Petersboury of
the 2d, the day he died. The same journal of the
2d publishes the following bulletin :
"His Majesty the Emperor is unwell. His illness
was at first only the 'grippe,' but since the 10th (22d)
February fever manifested itself, with slight attacks of
gout.
"Yesterday his Majesty felt pain in his right lung,
and the fever was much greater. During the night the
august invalid did not sleep.
"To-day the fever has somewhat diminished, and ex-
pectoration takes place without difficulty.
"M. MANDT.
" ENOCHIN.
"Dr. E ABELL.

" Feb. 17 (March 1), 1855."
An extraordinary Supplement contains another
bulletin

"FEB. 17 (MARca 1), 11 P.M.

" The following change has taken place •in the state
of his Majesty :—Towards evening fever increased, and
the expectoration from the affected part of the lower
.right lung has become more difficult.

The Nord Deutsche Zeitang publishes the fol-
lowing details of the event of the 2d March, which
it says it has from an authentic source :
" When the Emperor Nicholas was taken ill, the
Grand Duke Alexander was alone at St. Petersburg,
but the Grand Duke Constantine was summoned by
telegraph, and still found his father alive. In presence
of his brother, the dying Czar placed the reins of Go-
vernment in the hands of the Czarewitch, and the Grand
Duke Constantine promised to obey him as a faithful
subject.
"A few moments afterwards the Emperor expired,
and the high dignitaries of the Empire hastened to the
Palace in a complete state of stupefaction. The Grand
Duke Czarewitch declared his intention of assuming. the
Government of the Empire under the name of Alex-
ander 11., and he was immediately proclaimed Emperor.
On the 2d of March the Emperor Alexander received
the homage of the high functionaries of the empire and
of the troops of the garrison ; and at a council of
Ministers held by the young sovereign, it was decided
that the course of hostilities should not be interrupted in
any manner whatsoever."
A letter from Hamburg, dated the 2d instant,
gives the following details respecting the move-
ments of Russian troops in Poland :

" Letters dated Warsaw, the 28th of February, which
reached Hamburc, this evening, state that, independently
of the great number of the civil governors of the pro-
vinces sent for by Marshal Paskiewitch on his return
from St. Petersburg, many generals commanding Rus-
sian corps in Poland had proceeded to the capital of
that kingdom. The commander of the second infantry
corps &armee, General Paniutm, had a conference with
the Marshal on the 26th ; that general had transferred
his head-quarters to Lublin, whence the four divisions
which form his corps d'armee extend to the towns nearest
the provinces of Volhynia and Podolia.
" It was said in military circles at Warsaw that the
number of Greeks who came to offer to take service in
the Russian army had increased daily. They arrived in
bodies of a hundred at a time. On being formed into
battalions they are immediately marched to the Crimea,
where, it is said, they already muster 4,000 strong.
" Among the generals sent for by Marshal Paskie-
witch, and arrived at Warsaw, is General Essen, who
commands the Grenadiers h Cheval of the Imperial
Guard quartered at Siedlec and Miendzorzec. This
general has received orders to take up new positions.
" A detachment of Cossacks, it is said 4,000 strong,
had left Siberia for Poland."

Writing on the 3d, the same correspondent
says :
" Notwithstanding the sad event which has plunged
Russia into mourning, I continue t• chronicle the posi-
tions of the different bodies of troops which occupy
Poland and the provinces of the Baltic coast.
"During the last days of February there were five
regiments of cavalry in Courland and Esthonia destined
to be incorporated in the active army of the Baltic under
General of Cavalry Siewers.
" A regiment of Hussars, 1,200 strong, in eight
squadrons, commanded by Col. Gottschalk, had arrived
at Mittau, and extended its pickets as far as Tauroggen.
" Another regiment of Hussars, also 1,200 strong, in
eight squadrons, belonging to the brigade of General
Paleolog, was quartered partly at Telschen, partly at
Korcian.

" Two regiments of Uhlans, at full war complement,
each of 1,200 men, in eight squadrons, occupy their
wintor quartora at gossienen and Taureggen.

" Between this latter place and Libau there is a regi-
ment of regular Cossacks, 900 strong, or six squadrons
of the brigade of General Grikoff, wbo, with his staff, is
at Libau ; this cavalry regiment is echelonne along the
frontier from Libau to Tauroggen, and, like thy first
four, forms part of the array of General Siewers.
" Five regiments of infantry and a brigade of artillery,
under General Schwebs, had arrived to garrison Narva,
Riga, and Revel ; and two regiments of infantry and of
reserve entered Mittau in the last week of February."

A letter from Helsingfors says that the new: Go-
vernor-General, General von Berg, was on a tour of
inspection along the coast of the Gulf of Bothnia.
It acids that 11 large mortars had recently arrived
at Helsingfors, and were the object of the greatest
curiosity. It took 13 artillery horses to move each
of them. Their bore is from 10 to 12 inches in
diameter, and they throw shells of 120 pounds
weight.
