Exempla

“Si vero⟳ ob aliquam causam Missa in cantu non celebratur, Missa privata SS. Sacramenti legi poterit in iis diebus in quibus per rubricas licet⟳, nempe quocumque die officium non est duplex, aut de Dominica, aut dies in qua prohibetur fieri de festo duplici.”

But if for some reason a sung Mass is not celebrated, a Low Mass of the Holy Sacrament may be read on those days on which it is licit according to the rubrics, whenever, of course, the office of the day is not a double, or that of a Sunday, or a day on which it is prohibited to be of a double feast.
