A work of extreme interest to geologists is the _Gaea Norwegica_, edited by Professor KEILHAU of the Christiana University, and published at that place. The first volume is just completed. No country of Europe is more important in respect of geological science than Norway, and the labors of Professor Keilhau and his associates are of the most thorough and solid kind. The volume contains 516 pages folio. Cost in America $4.50. * * * * * A GERMAN nobleman lately wrote to the French Academy, offering to give that body a yearly income of 10,000 francs to be spent in two prizes, one of 5,000 francs for the best essay in defence of Catholicism, and another of the same sum for the best essay in defence of Absolutism. The Academy declined the offer. * * * * * A SYSTEM of _Christian Ethics_ has lately been published at Regensburg, by Dr. WERNER, Professor in the Catholic Theological Seminary of St. Polten. The writer holds that all virtue flows from the mystic fountain of regeneration, and is confirmed and supported solely by the sacraments of the church. * * * * * WILHELM MEINHOLD, author of the _Amber Witch_, lately the pastor of a parish in Pomerania, is now in Berlin, preparing for admission into the Roman Catholic Church. It is not long since he forfeited his place in the Protestant Church by a street fight, for which, we believe, he was imprisoned. * * * * * The College of Rabbis, at Padua, offers 1000 florins ($400) as a prize for the best descriptive and critical work on the political and religious history of the Israelites from the first siege of Jerusalem to the time of the latest writers of the Talmud. * * * * * MRS. ROBINSON'S (_Talvi's_) History of the Colonization of America, originally published in the German language, has been translated by Mr. William Hazlitt, and printed in London. * * * * * GEDICHTE VON JEANNE MARIE (Poems by Jeanne Marie) is the title of one of the latest products of the German muse. The authoress is well known and well liked by those readers of German novels who take delight in the genius of authoresses, and think ladies can write as well as men. Jeanne Marie has seen much, felt much, and thought almost if not quite as much as she has seen and felt. Her poetic culture is however still defective, and her stories are better than her lyrics. The latter lack finish and correctness, and abound in mere conceits rather than in genuine poetic images. Where she attempts simply to narrate an event in the ballad style she is more successful. * * * * *
