AUSTRIA.

Count Buol has issued the following circular to
the Austrian diplomatic agents at all the Govern-
ments of the German Confederation :
" VIENNA, APRIL 28.
•

" The Imperial Government had agreed with the Royal
Court of Prussia to abstain from provoking a debate in the
German Diet on the case provided for by Article 47 of the
final act of the Congress of Vienna until the intention of
France to take part in a war between Austria and Sardinia
should have been formally expressed.
" That moment has now arrived, the French Charge
d'Affaires, the Marquis de Banneville, having declared to mo
on the 26th, in consequence of orders he received by tele-
graph, that his Government would regard the passage of
the Piedmontese frontier by Austrian troops as a cams
belli ; and France has not even waited for that event to
march French troops into Sardinia.
" Meanwhile we have also received the evasive reply from
Turin, and at the same time news of a military revolution at
Florence, and risings at Massa and Cararra, in consequence
of which our troops have been ordered to enter Piedmont.

Under these circumstances, we can no longer delay express-
ing ourselves at Frankfort, and we charge Count de Rech-
berg to hand to the Diet, in an extraordinary sitting to be
held, if possible, on Monday next, the subjoined declara-
tion, of which I send you a copy.
_ .

" I beg of you to communicate it without delay to the
Government to whfch you are accredited, expressing the hopo
that the result will be the mobilisation of the federal army,
and that the representatives of each Government will re-
ceive instructions to urge that resolution upon the Diet.
(Signed) " DE BUOL."

A Vienna letter in the Cologne Gazette says :
" Austria has already on foot upwards of 600,000
men, well equipped, of whom. 300,000 are in Italy.
In a fortnight her army will be 800,000 strong. In
all the provinces volunteers are flocking in. At
Vienna about 1000 men enrolled themselves yester-
day, and the Ist battalion of volunteers can march

in a few days. The Hungarian nobility are raising
five regiments of hussars, and at Arad thousands of
men are flocking in. Similar enthusiasm prevails
in Bohemia, Moravia, Styria, Upper Austria, the
Tyrol, and Carinthia. All these provinces supply
volunteers equipped at their cost, and young men
go in crowds to engage themselves. The two regi-
ments of cavalry, Prince Liechtenstein and Arch-
duke Ernest, are to be concentrated in Upper Aus-
tria, being destined for Germany. The Hereditary
Grand Duke of Tuscany has resolved to enter the
Austrian army and to serve in the war ; he is
already nominally colonel of the Bth Dragoons."
" Austria," says a Berlin letter, " has not yet
abandoned all hope of inducing Prussia to take part
in the struggle. She has contrived to bring into
play the diplomacy of the petty Courts, which have
till now been closely allied with Prussia. This is
particularly the case with the Courts of Anhalt and
some of the Thuringen. The incessant goings and
comings of M. de Plcetz, Minister of State of
Anhalt, seem connectcd with these intrigues, but
they have met with no success. The Prince Regent
has declared that Prussia will not be induced by
pressure from without to take any step which she
does not consider compatible with her own inte-
rests ; that the Cabinet of Berlin would not suffer
other States to exercise any influence on its action,
because it well knew the line it ought to follow ;
and that, if Austria succeeded in getting certain
measures adopted by the Germanic Diet, Prussia
would be obliged to separate her policy from that
of the other States of the Confederation,
