The second part of the third volume of HUMBOLDT'S _Kosmos_ is nearly completed, and will soon appear. A fourth volume is to be added, in which the geological studies of the venerable author will be set forth. He is now nearly eighty-one years old, and is as vigorous and youthful in feeling as ever. The first part of the third volume of _Kosmos_ appeared in German and English several months ago. * * * * * A History of Polish Literature, from the remotest antiquity to 1830, is now being published at Warsaw, by Mr. MACIEJOWKI, a writer thoroughly acquainted with the subject. Three parts of the first volume have appeared, bringing the history down to the first half of the seventeenth century. One more part will complete the volume, and three volumes will complete the work. * * * * * The study of Russian archæology and history is prosecuted in that country with a degree of activity and thoroughness that other nations are not aware of, and publications of importance are made constantly. Within the present year the fifth part of the complete collection of _Russian Chronicles_ has appeared, the fourth of the collection of public documents relating to the history of Western Russia, and the beginning of a new collection of foreign historians of Russia. * * * * * A curious contrast of light and shade is exhibited in the titles of two works recently published in Vienna. SIEGFRIED WEISS (or _white_) puts forth a book, _On the present state and trade policy of Germany_, while in the next paragraph of the same list N. SCHWARTZ (or _black_) appears as the author of _The situation of Austria as regards her trade policy_. This latter we should judge to be an excellent illustration of the old phrase, "_nomen et omen!_" * * * * * Periodical literature is making its way into Asia. A literary monthly has made its appearance at Tiflis, in the Georgian language. It will discuss Georgian literature, furnish translations from foreign tongues, and treat of the arts and sciences, and of agriculture. What oriental students will find most interesting in this magazine, will be its specimens of the popular literature of the country. A new Armenian periodical has also been commenced in the Trans-Caucasian country. * * * * * A German version of HAWTHORNE'S _Scarlet Letter_ has been executed by one DU BOIS, and published by Velliagen & Klasing of Nielefeld. * * * * * OTTO HUBNER, the industrious German economist, is about to publish at Leipsic a collection of the tariffs of all nations. * * * * * A work on Freemasonic medals has been published by Dr. MERZDORF, superintendent of the Grand Ducal Library of Oldenburg: with plates. * * * * *
