The sphere of numismatics is filled by a long essay by Cavedoni on the Roman coins of the time of Augustus. There are also many other articles of no less interest to scholars, antiquaries, and artists. * * * * * M. ANTOINE D'ABBADIE received not long ago from President Bonaparte, the decoration of the Legion of Honor, for alleged geographical discoveries in Africa. An "Inquiry" into M. Abbadie's journey has just appeared in London, from the hand of Dr. Charles T. Beke, and it is not impossible that the traveller will turn out a Damburger or a Hunter. Dr. Beke is an Englishman; D'Abbadie, an Irishman by birth, but a Frenchman by name, education and allegiance. The latter professes to have been the first European who ever put foot in the African Kingdom of Kaffa; the former gives reasons for doubting his statements entirely, and does not believe the Frenchman has even been in the country he describes at all. * * * * * The great oriental scholar Monsignore MOLSA has been appointed to the office of Chief Guardian of the Vatican Library, in the room of M. Laureani, whose melancholy death occurred a few months ago; and the Abate Martinucci has been nominated to fill the office of sub-chief, which is one of very considerable importance, and has hitherto been filled by some of the most eminent of Italian scholars. * * * * * We are to have from Paris a hitherto unpublished ode of PIRON, the well-known author of _La Metromanie_. It is entitled _Les Confessions de mon Oreiller_, (Confessions of my Pillow,) and is considered by connoisseurs to be decidedly authentic. It is signed and headed thus: "To be given to the public a hundred years after my death." * * * * * The vacancy occasioned by the death of M. ALBAN DE VILLENEUVE-BARGEMONT, in the list of members of the French Academy of Moral and Political Sciences, has been filled by the election of M. LOUIS REYBAUD, the author of _Jerome Paturot_, and husband of Madame Reybaud, who wrote the charming novels of _Le Cadet de Calabriere_, _Helena_, &c. * * * * * The sons of Rossi, the distinguished economist, and less distinguished minister of Pius IX., in which capacity he was assassinated, have published the third volume of his _Cours d'Economie Politique_. It treats of the distribution of wealth, and is marked by the same ability and tendencies as the volumes which preceded it, which were upon the production of riches. * * * * * H. BAILLIERE, the eminent publisher, of Paris, has established a branch of his house at 169 Fulton street, New-York, where American scholars may obtain all the best scientific literature of the time in suitable editions and at reasonable prices. * * * * *
