OUR OWN CORRESPONDENT.) _ _  PARIS, Friday Evening.  The Siecle says :—" The news is confirmed that the naval and military forces of Austria in Venetia are placed upon the war footing, and the reserve is called into activity. The Nazione of Florence supposes that these demonstrations are directed rather against Prussia than against Italy, unless—a circumstance which merits consideration—Austria has the secret thought of thus provoking some inconsiderate act calculated to compromise the policy hitherto followed by the Italian Government. Some of the Vienna papers appear to have serious fears of the influence of the party of action in Italy : they appear to foresee that the nation and the Government will be forced into a campaign against Austria, and insist that proofs exist of a secret understanding between Italy and Prussia." The Journal des Debuts says :—" The correspondence of the day confirms the statement of the extraordinary armaments of Austria in Venetia. The Borsenhalle announces that the Archduke Albert will leave immediately for Verona. The Archduke will take the command of the Quadrilateral Army, and relieve Marshal Benedeck, who will remain at the disposal of the Emperor. The same paper adds that at the last Council of Ministers held at Vienna it was decided to make military preparations upon a very extensive scale. We know not whether this information be well founded ; but, even allowing for a little exaggeration, there is no doubt whatever of the preparations in question, and it is strange to see Austria push its armaments with such activity in the South, at the moment that it is disarming in the North."

An eminent soldier, :General Herbillon, has just died. He entered the army in 1813, and was in many campaigns. General Herbillon was in the Senate for three years, but was not distinguished as an orator. It was in the field that he achieved his reputation. He was appointed Field-Marshal in 1846.  A mysterious story is told by some of the Paris papers of the arrest of a man in London who murdered a noble lady at her hotel in Paris in 1847. An individual was arrested in Paris at the time upon the charge, but he managed to poison himself with arsenic. The account now given is that the murderer is in London, and that his supposed corpse was substituted for that of the real murderer. This is a complete fabrication. The body of the man who poisoned himself was dissected by two very eminent surgeons, M. Orfila and M. Tardiem, and their certificates, as well as those of the police authorities, leave no doubt as to the proof of the identity of the individual who was arrested in Paris at the time.  There has been an attempt at murder in the Rue du Faubourg, Montmartre. A man named M. rushed into the room of M. D., who is engaged at the Folies Dramatiques, while he was engaged at dinnor with his wife, and, without saying a word, fired a pistol at him. The ball struck near the heart, and M. D. is not expected to survive. The motive of the attempted murder is said to be that the wounded man formerly had a criminal acquaintance with the wife of the assassin. It is officially announced that the Paris Exhibition of the paintings of living artists will be opened on Tuesday next. The price of admission is 1 fr. on week days, and on Sundays the exhibition will be opened gratis.  It appears from the researches of M. Victor Le Clerc, of the Sorbonne, relative to the newspapers in France, that there were political and literary journals in the time of the Romans. The Venetians in the 17th century had a newspaper destined chiefly for the use of shipowners. The second newspaper created chronologically was that of Theophraste Renandot, physician to Louis
