directly published by the Holy See, the names of persons and places will be thoroughly suppressed or altered, and the substance of the fact only will be given in the way in which moral cases are usually proposed. The contents of the first number are as follows. After the preface there is a full discussion of the important practical question touching _missarum iterationem_, _applicationem missae pro populo_, _et receptionem eleemosynae_. This discussion, with the decision of the Congregation, etc., we have given above. Next follows: _Circa nullitatem matrimonii ratione, raptus_. Next follows: _Juris funerandi et restitutionis emolumentorum seu causa orta, occasione publici coemeterii noviter erecti_. Next comes an appendix, _quod jus funerandi_ (_pag. 24_). We shall have frequent occasion for the future to recur to this valuable collection. II. _Grammar of Gregorian and Modern Music._ Originally compiled by the Very Rev. L. F. Renehan, D.D., late President of Saint Patrick’s College, Maynooth. New and enlarged edition, containing numerous exercises, the Gregorian Chants for High Mass and the Divine Office; Litanies of the Blessed Virgin, instructions regarding the use of the organ, etc. By the Rev. Richard Hackett, Professor, Saint Patrick’s College, Maynooth. Dublin: James Duffy. 1865, xxiv.――297. 12mo. This useful book is divided into five parts. The first part (p. 1-68) is a reprint of the _Choir Manual_ published by the late Dr. Renehan for the use of the students of Saint Patrick’s College, Maynooth, and republished with additions in 1858 by the accomplished editor, or rather author, of the work under notice. This part contains a complete explanation of the theory and notation of Gregorian music, with some elementary instructions in modern Italian music. The remaining four parts and appendix (p. 69-297) we owe to the Rev. R. Hackett himself. The purpose of his labour has been to supply ecclesiastical students in this country with a complete manual of the principal chants which are sung at High Mass, Solemn Vespers, Benediction, Mass and Office for the Dead, etc. With this view he has collected into the second part an abundant supply of exercises on the intervals ordinarily in use in Gregorian music, together with a selection of easy chants in which these intervals occur. Part the third contains the principal chants of the office for the dead, of the Mass for the dead, and instructions on the method of chanting prayers. It is greatly to be regretted that there should exist a difference between the Roman method of chanting prayers and that in use in some dioceses in Ireland. We hope that, as far as Ireland is concerned, by help of the judicious selection of Roman chants given in this work, we may soon be able to say with Guidetti (quoted by our author at page 134), though in another sense, _semper et ubique sic cantatur_. The present want of uniformity, appears still more unseemly when we learn (p.
