The translation of these admirable studies of the great Jesuit, although done in moments snatched from the time of a Visitation of a large parish, has brought the translator much pleasure and instruc tion.

Intended as it is to increase loye and reverence for the great central act and feature of Catholic worship, the Holy Sacrifice of the Mass, its ceremonies and symbols. A distin guished author not of the household of faith, seeing but dimly and as through a glass, considered the Holy Sacrifice.
