This tract is a treatise on the life and writings of an humble and laborious monk of the early ages in Ireland, who published, if we may use the expression, his _Felire,_ Fessology, or Calendar of Irish saints, as long ago as 804. From the biographical and historical value of this poetical work, St. AEngus ranks among the very earliest of the historical writers of modern Europe. In this view, no less than to draw attention to one whose holy life induced the Irish church to ascribe his name on the dyptics, it is well that the present generation should be asked to pause and look upon this life, so humble, laborious, and holy, and which so strongly commended him to the veneration of succeeding ages. The Rev. Mr. O'Hanlon treats his subject systematically, displaying great research and sound criticism, and it is to be hoped that his treatise will induce some of the publishing societies in Ireland to issue an edition of the works of this venerated father of the Irish church. The _Felire_ of St. AEngus consists of three distinct parts: the first, the Invocation, containing five stanzas, implores the grace of Christ on the work; the second, comprising 220 stanzas, is a preface and conclusion to the main poem; the third part contains 365 stanzas, one for each day of the year. They comprise not only the saints peculiar to Ireland, but others drawn from early martyrologies. This poem was regarded in the early Irish church with great veneration, and the copies that have descended to us have a running gloss or commentary on each verse, making it a short biography of the saint briefly mentioned in the poem. {142} In this form its value has long been known to scholars, whose frequent use of it shows the light it frequently helps to throw on Irish history and topography. We trust that the work of the Rev. Mr. O'Hanlon will not be fruitless. ---------- Essays And Lectures on, 1. The Early History of Maryland; 2. Mexico and Mexican Affairs; 3. A Mexican Campaign; 4. Homoeopathy; 5. Elements of Hygiene; 6. Health and Happiness. By Richard McSherry, M.D., Professor of Principles and Practice of Medicine, University of Maryland. Baltimore: Kelly, Piet & Co. 1869. Pp. 125. The Early History Of Maryland. The sketch of colonial Maryland is drawn with a masterly hand, showing, in the first place, the author's thorough knowledge of its history; and, secondly, the poetic language in which his ideas are couched tell plainly how completely his heart is imbued with love for his native Terra Mariae. Dr. McSherry is right when he calls his State "the brightest gem in the American cluster." To the Catholics of this broad land it is surely so; and the names of Sir George Calvert and his noble sons, the founders of this "Land of the Sanctuary," should be enshrined with love and reverence in the hearts of all who profess the old faith and appreciate our religious liberty.
