An extract of a private letter from Rome states that the Coliseum is in process of restoration.

Lessing's great picture—"The Martyrdom of Huss," is described at length by a Düsseldorf correspondent of the Leipzig Grenzboten. It is eighteen feet by fifteen, and contains some twenty-seven figures of the size of life; which, contrary to the practice of the French painters in pictures of this size, are so carefully finished, that they can be looked at close at hand. There is not a superfluous figure in the picture—none introduced to fill a space, as is too frequently the case in large paintings. The clearness of the general idea is not marred by the effect of the separate parts: the artistic separation of the group suffers the main figure first to attract the eye. In this picture Lessing has given proof of his ability in landscape as well as in figures. The next work upon which he is to be engaged is a large picture, commissioned by the King of Prussia, representing the imprisonment of Pope Paschal by Henry V.

An association has been formed in Jerusalem for the investigation of subjects connected with the Holy Land, including history, language, numismatics, statistics, manufactures, commerce, agriculture, natural history, and every other subject of literary and scientific research, with the exception of religious controversy. From the names of those engaged in the project, it is hoped that the association will make large additions to our present stores of information respecting Palestine.

The Leipzig journals contain notices of the recent productions of Polish literature, which are not without interest even in this country. A romance, by the Countess Ludwica Offolinska, recently published at Cracow, has excited considerable attention. It is entitled "The Fate of Sophia," and is written with great simplicity, and the deepest religious feeling. The heroine receives at home a religious training, and then is thrown out into the world. She appears in succession as the waiting-maid, and then the friend of her mistress; then as maid to a worn-out woman of fashion, and at last as governess to the children of her first beloved mistress and friend. The sound principles she had learned at her father's house, serve her as a defense amid all the perils which surround her in her career. The same authoress has put forth two comedies: "The Holy Christ," and "Vespers in the Country."

Vincent Pol, a poet, and for a short time Professor of Geography in the University of Cracow, is one of the most distinguished geographers of the day. His "Glance at the Northern Waters of the Carpathians and their Districts," is an earnest of important contributions to geographical science from the Slavic countries.

F. Antoniewicz, an ecclesiastic, has published "A Festival-day Lecture to our People," written with great eloquence. Rychcicki, otherwise known as a historian, has put forth a "History of the celebrated Chancellor Skarga, and a Description of the Century in which he lived."

From the Warsaw press have appeared, among other works, "A Lexicon of Polish Painters," comprising all artists who were born, or lived in Poland, or whose works refer to that country. It is by Rastawiecki, contains two volumes, and is ornamented with portraits. Dorbrski's "A Few Words more about the Caucasus," is a continuation of a former work.

From Wilna appears the "Athenæum," by the prolific Kraszwski. It contains from the pen of the editor a work of great value, "Lithuania under Witold," and a romance. "The Wilna Album" contains seventy sheets of views of interesting and remarkable places in that city.

Brockhaus, the great Leipzig publisher, announces a translation into German of Ticknor's History of Spanish Literature, by Dr. R.H. Julius, of Hamburg; with the assistance of Ferdinand Wolf, of Vienna, and other scholars. The German editor has labored for several years in this department of literature, and will also avail himself of Dozy's learned work on Arabian-Spanish literature, which appeared in Holland in 1849.
