The venerable Dr. MURRAY, Roman Catholic Archbishop of Dublin, died at his residence in that city on the 25th of February. The death of this excellent prelate, whose life has been a model of Christian forbearance in a country where such an example is invaluable, the journals say is deeply regretted by moderate men of all the religious denominations of the country. * * * * * Dr. M'NICHOLAS, titular Bishop of Achonry, died about the middle of February. He was regarded as one of the ripest scholars among the Roman Catholic hierarchy of Ireland, and belonged to the advanced school of "educationists." * * * * * The London papers announce the death of Mr. HOLCROFT, son of the more famous Thomas Holcroft, the dramatist,--who was for many years connected with the press, and, perhaps, in that capacity most prominently known as the musical and dramatic critic of one of the leading daily papers. * * * * * M. BENCHOT, the editor of Voltaire's works, lately died at Paris. He devoted thirty years to studies preparatory to the execution of his undertaking, which he finally completed in 1834. He also published in 1811 a laborious work on French bibliography, which is still a standard manual. * * * * * JOHANN KOLLAR, Professor of Slavonian antitiquities at the University of Vienna, died on January 24th, last, in his sixtieth year. He was born at Mursotz, in Hungary, and was educated as a Protestant clergyman; he was appointed Professor in 1849. He contributed greatly to the intellectual movement of recent years among the Austrian and Prussian Slavonians. His literary reputation was first established by _Slavy dcera_ (The Daughter of Fame) a lyrical epic poem, published in 1824. His ideal end was the creation of an independent Slavonic literature, which should preserve his race from the ever increasing influence of German culture, by which he foresaw that it must be absorbed, unless it could be aroused to a development strictly its own. During the Hungarian war he remained an adherent of the Austrian side. He leaves two nearly finished works; the one is _Slavonic Italy in Early Times_; the other is upon Slavonic Mythology, and is entitled _The Gods of Retra_. They are written in the Bohemian or Tschechic language. * * * * * The widow of VON KOTZEBUE, the author of _The Stranger_ and _Pizarro_ (the former of which still keeps possession of the German provincial stage), who was assassinated at Mannheim by the student Sand, died at Heidelberg, on the 4th of February, at the age of 73. She was Kotzebue's third wife, and had lived for many years in strict retirement. * * * * * BARON KRUDENER, Russian Minister in Stockholm since 1844, died early in February. * * * * *
