We are still without decided news from Poland. The only
in- telligence is a report of PASKEWITSCH, which states that he had passed the Vistula without opposition—a fact previously known ; and an insidious note from ROZNIEKI, former Director of the Secret Police of Warsaw—a scoundrel virtute °Sidi—in which he says that DIEBITSCH was the grand cause of the harshness with which the approaches of the Poles have been hitherto treated ; and that PASKEWITSCH is quite another guess sort of man—gentle and easy to be entreated. There was a report in the beginning of the week, that NICHOLAS had followed CONSTANTINE, and by the same road ; but it wants confirmation. The ravages of the Cholera are, however, terrible, both at. St. Petersburg and War- saw ; and we have proof that neither prince nor peasant are safe from attack.
