A publication worthy of the utmost praise is the _Revue de l'Architecture et des Travaux Publiques_, published at Paris, under the editorial care of M. CESAR DALY, one of the most learned and accomplished architects in Europe. This review, which is now in its ninth year, is issued monthly, with the utmost elegance both of typography and engravings. The number for October contains articles on the following subjects:--the preservation and restoration of the Cathedrals of France, the Church of St. Paul at Nismes, Stereochromy, the Museum at St. Petersburg, Chinese Monuments discovered in Ireland, the Public Garden and Swimming School at Bordeaux, &c., &c.; it has four large engravings. The work treats every branch, historic and practical, of architecture and engineering, and should be in the hands of every architect and engineer, and in the library of every man of taste whose leisure and meditations lead him to the study of the beautiful and useful arts. It may be procured in Paris at the low rate of 40 francs a-year. * * * * * A book well suited to the times is Dr. FIGUIER'S _Exposition et Histoire des principales Découvertes Modernes_, which has just appeared at Paris in two small volumes. It treats of photography, the serial and magnetic telegraphs, etherization, galvanoplasty and chemical gilding, aërostatics, lighting by gas, Leverrier's planet, gunpowder, and gun-cotton. With respect to the glory of discovering photography, Dr. Figuier restores it to M. Niepce, of Chalon-sur-Saone, proving that he originated the conception, and that Daguerre did nothing more than perfect the process. Singularly enough, M. Figuier omits the steamboat and railroad from the discoveries whose history he so carefully and conscientiously records, but even with these omissions his work is valuable and interesting both to the savan and the ordinary reader. * * * * * The editors of the _Revue des Deux Mondes_, at Paris, have made up a very useful manual of the history of the year 1850, under the title of _Annuaire des Deux Mondes_, which is sold by Balliére, in Broadway. It contains an account of the political events, the international relations and diplomacy, the administration, commerce, and finances, and the periodical press and literature of every country which possesses those products of civilization. The constitutions and affairs of Italy, Denmark, Germany, France, Belgium, Switzerland, Spain, Portugal, England, Norway, Sweden, Russia, Turkey, Greece, United States, Mexico, the South American Republics, and even of the African and Asiatic races, are discussed with moderation and an effort for impartiality, which is laudable, if not always successful. The most recent statistics are given with reference to every country; and, as a book of reference, it will be found very useful.
