NEW GERMAN POEMS.--Louise von Ploennies has published two new books of poetry, one under the title of _Neue Gedichte_ (New Poems), the other _Oskar und Giaunetta_. They are spoken of as superior to her former productions, and worthy of a most honorable place among the productions of German poetesses. Oscar and Giaunetta is a love story in verse. The purpose of the writer is to exhibit the masculine and feminine principles, Thought and Beauty, as mutually completing each other in the passion of love. The _Monates-Maehrchen_ (Tales of the Month), by Gustar von Mayem, are poems of another sort. Instead of sentimentality, the stock in trade of this writer is patriotism and politics. His inspiring thought is the unity of Germany and the national greatness which must result therefrom. Unfortunately this thought does not find so welcome a reception with statesmen as with poets. * * * * * A PRODUCTION of the most indisputable German plodding and erudition is the _Satzungen und Gebraeuche des talmudisch-rabbinischen Judenthums_, by Dr. I. F. Schroeder, lately issued at Bremen. It gives a complete account of the religious notions, doctrines, and usages of the Jews. To theologians it is of high value for the light which it casts upon the formation and institutions of the Christian Church. The author has employed in its composition the writings of every sect, and has condensed in it the result of a thorough study of the entire literature relating to the Old Testament and the rabbinical writings. He writes with the greatest impartiality, and in the interest of no particular creed or tendency. * * * * * M. ARAGO said lately in the Academy of Sciences, upon the suggestion of some possibilities in aerostation, that a long time since the whole subject had been treated in a masterly manner by Mousnier, a celebrated member of the Academy of Sciences. His treatise had remained in manuscript in the public library of Metz, and if it should be committed to the press, it would prove to those who think they have discovered new methods of aerial locomotion, that what is plausible and rational in their ideas was already perfectly well known, expounded and appreciated, in the last century. * * * * * THE government of Naples constantly increases its list of prohibited books. Among the works now excluded, Humboldt's Cosmos, Shakspeare, Goldsmith, Heeren's Historical Treatises, Ovid, Lucian, Lucretius, Sophocles, Suetonius, Paul de Kock, Victor Hugo, E. Girardin, G. Sand, Lamartine, Valery's L'Italie, Goethe, Schiller, Thiers, A. Dumas, Moliere, all the German philosophers, and Henry Stephens's Greek Dictionary. * * * * * THE ABBE LACORDAIRE has published an introduction to a work entitled _Le Monde Occulte_--an exposition of the mysteries of magnetism, by means of somnambulism. * * * * *
