Gargan examines the silence observed about the mission from Rome:--1. in the _Confessions_, and the _Epistle to Coroticus_; 2. in the _Hymn of Saint Sechnall, or Secundinus_; 3. in the _Hymn of Saint Fiacc_; 4. in the _Life of Saint Patrick_ in the Book of Armagh. Under the heading, "Dr. Todd's Chronological Difficulties against the Roman Mission of Saint Patrick", the author refutes the arguments drawn from various sources to show that Saint Patrick did not commence his apostolic life in Ireland before A.D. 440, wherefore, Pope Celestine having died A.D. 432, the mission from Rome cannot be admitted. Finally, 6. the incompleteness of the memoir is brought as a charge against its author. "With all that Dr. Todd has written concerning our apostle, we are left strangely at a loss to know whether the form of Christianity which he introduced into our island in the fifth century was in harmony or at variance with Catholicity as then prevailing in the east and west, and as still prevailing in all churches in connection with the chair of Peter" (page 107). This is a grave charge indeed, and we agree with the learned professor in believing that it seriously interferes with the claims which Dr. Todd's work has to be considered a guide in the questions that every now and then are agitated concerning the Irish Church. In the face of this well-grounded charge of incompleteness, how can the _Press_ say that "no one will be qualified to do justice to that vexed and intricate question, who has not made himself master of the facts connected with the early institution of that Church, of which Dr. Todd has shown himself the truthful and laborious expositor"? III. _De residentia beneficiatorum, Dissertatio historico-canonica, quam ad gradum doctoris sacrorum canonum in academia Lovaniensi consequendum, conscripsit Ludovicus Henry, juris canonici Licentiatus._ Lovanii, 1863 (238 pp). This book contains eight chapters. The two first treat of general principles, and the remaining chapters discuss how far residence is obligatory upon cardinals, bishops, canons, parish priests, curates, and those holding simple benefices. Each chapter is ordinarily divided into two parts; the first treats of the ancient discipline, the second of modern discipline, such as the Council of Trent and the Apostolical Constitutions have made it. Dr. Henry has consulted good authorities: Thomassinus for the ancient law; the Decrees of the Sacred Congregations and the Roman Canonists have furnished him with principles to solve the various cases to which modern discipline has given rise. We omit to notice the obligations of cardinals, bishops, and canons in the matter. As to parish priests, the author has carefully made a collection of the decisions regarding their obligation to reside in their parishes. We shall be satisfied with citing such as bear upon really doubtful cases.
