I. _Appendix ad Rituale Romanum_ sive Collectio Benedictionum et Instructionum a Rituali Romano exsulantium, Sanctae Sedis auctoritate approbatarum seu permissarum, in usum et commoditatum Missionariorum Apostolicorum digesta. Romæ, Typis S. Con. de Propagande Fide, 1864. This book has been compiled by authority, to serve as an appendix to the Roman Ritual, and is intended for the convenience of priests on the mission. In Ireland especially, where the Catholic instincts of the people have ever maintained pious confraternities in the honour which is their due, the clergy must have felt the want of a manual containing the _formulæ_ to be used in enrolling the faithful in the various religious societies approved by the Holy See. These forms are not to be found in the Roman Ritual, nor in the books easily accessible to the great body of priests. Besides, since every creature of God may be blessed by prayer, the Catholic Church, whilst she refuses to be reconciled with whatever is defective in modern progress, hastens, on the other hand, to sanctify by her blessing whatever this progress contains of good. Hence, new forms of prayer are rendered necessary from time to time, such as the form for blessing railways, and the Benedictio ad. OMNIA, to be used in blessing all objects for which a special benediction is not contained in the Roman Ritual. These forms are to be found in this appendix. The instructions which the Holy See issues from time to time on various subjects for the guidance of missionary priests, also find their place in this collection. Among them is the Instructio, issued by the Sacred Congregation of Rites, for those who have permission to say two Masses on the same day in different churches, and which is inserted in the Ordo for use of the Irish clergy. To this is added, in the book under notice, the ritus servandus a _Sacerdote cum utramque Missam in eadem Ecclesia offere debet_. It runs as follows:—
