2. Cours De Liturgie Romaine Le Breviare, L'abbe Bernard, Sulpician (Paris. 1887, 2 vols, 7 francs). This is a text-book written with great care, showing fine scholarship and deep piety. It is the work of a skilled teacher.
3. Le Breviare Romain, Commente par L'abbe Maugere. Paris. 1887, 6 francs.—A very concise and useful work, which I have used often in compiling my book.
4. The articles in the Catholic Encyclopedia, on the Breviary and liturgy generally.
5. Duchesne, Christian Worship (London. 1904. 10s.). Very readable and serviceable to students of early Church history.
6. Battifol, History of the Roman Breviary. (London, 1912. 15s.)
7. Biron-Baumer, Histoire du Breviaire. (Paris. 2 vols. 11 francs.)
8. Baudot, The Roman Breviary (London. Cath. Truth Society. Price 4s.6d.)
Monsignor Battifol's book is well and favourably known. It is in English, and has had a large circulation. It received searching and severe criticism from Dom Baumer, the author of Geschichte des Breviers. Baumer's work (translated into French by Biron) is a work showing wonderful industry, learning and critical acumen. The great German Benedictine was aided in several parts of his work by Mr. E. Bishop, the English liturgiologist, who intended to translate the work into English. Dom Baudot's book gives in concise form the results of the labours of Battifol and Baumer. The book is readable, accurate, and is excellent value for the price.
9. The Calendar. The introductory matter given in the Breviary suffices for the wants of the ordinary student of liturgy. But those who wish for an exhaustive study of times and seasons may safely read Kalendarium Manuale, Pars I. Festa immobilia, Editio secunda; price 9 lire; and Pars. II. Festa Mobilia, price 13 lire, by Rev. N. Nilles, S.J. Calendar study is highly interesting, and the articles in the Catholic Encyclopedia and Father Thurston's articles in the Month on Calendar affairs are always instructive.
The New Psalter (Myers and Burton. London. 1915. 3s.6d.) is a very useful and practical help to the understanding and application of the new rubrics. I have quoted several times from its pages,
