Here is a work of remarkable erudition, and unusual interest for the classical scholar: _Notices sur Rome. Les Noms Romains et les Dignités mentionnées dans les Légendes des Monnaiés Impériales Romaines_. Par L'Abbé I. Marchant. Paris, 1869. Imperial 8vo. It is a learned dissertation upon the origin and signification of the titles, dignities, and offices mentioned in inscriptions on imperial Roman coins, the names, surnames, filiation, adoption, and dignities of emperor, Cæsar, Augustus, censor, pontiff, grand pontiff, princeps juventutis, proconsul, etc., etc.; the surnames taken from vanquished nations, _Britannicus_, _Germanicus_, _Dacicus_, _Pannonicus_, _Parthicus_, _Sarmaticus_; titles seldom merited, and grossly exaggerated, bestowed upon emperors by the servile flattery of senate or people, such as _Pater Patriæ_, _Dominus Noster_, _Senior_, _Pius_, _Felix_, _Felicissimus_, _Beatissimus_, _Nobilissimus_, _Optimus_, _Maximus_, _Deus_, _Divus_, _Æternus_, _Invictus_, _Triumphator Gentium_, _Barbararum_, etc. For empresses, _Augusta_, _Diva_, _Felix_, _Nobilissima_, _Fœmina_, _Mater Castrarum_, _Mater Augustorum_, etc., etc. Then follow the subordinate titles of _Questor_, _Triumvir_, _Prefect_, etc., etc. The work is by no means one of dry nomenclature, and the author, by his fulness of illustration and attractive style, has produced an admirable work. NEW PUBLICATIONS. CONVERSATIONS ON LIBERALISM AND THE CHURCH. By O. A. Brownson, LL.D. New York: D. & J. Sadlier & Co. This is the first production of the pen of Dr. Brownson which has appeared under his own name for several years. During this time he has been a constant contributor to this magazine, and has furnished a considerable number of valuable articles to other periodicals, particularly the _Tablet_, of which he has for some time past had the principal editorial charge. Those who are familiar with the leonine style of the great publicist cannot have failed to recognize it even in his anonymous productions, or to admit, whether with good or with ill grace, that he still remains _facile princeps_ in that high domain which he has chosen for himself. We welcome the venerable author most heartily on his reappearance upon the field of intellectual combat with his visor up, and his own avowed recognizance upon his shield. He appears as the champion of the encyclical of Pius IX. against that conglomeration of absurd and destructive errors which its advocates have decorated with the name of liberalism, and as the defender of the true, genuine principles of liberty--that liberty which Catholic training and Christian civilization prepare the greatest possible number of men to enjoy, to the greatest possible extent, with the least possible danger to themselves and society.
