Mangin is sending by mail a copy of the Kyriale, a little booklet of Gregorian Chant for the churches of this country. This and other books of the same collection have been arranged by the order and under the eyes of the late Bishop John Nepomucene Neumann of Philadelphia. They have been approved by several Bishops and introduced into their dioceses. He asks for Lefevere's approbation. Such approval will further their success, and be a reward for Mangin's labor and an encouragement for future work. :: III-2-j A.L.S. 1p. 8vo.
