On ordinary days Lauds shall be celebrated in the following manner: let the sixty-sixth psalm be said without an antiphon and somewhat slowly, as on Sunday, in order that all may assemble in time for the fiftieth, which should be said with an antiphon. After this let two other psalms be said according to custom: that is, on Monday the fifth and thirty-fifth; on Tuesday the forty-second and fifty-sixth; on Wednesday the sixty-third and sixty-fourth; on Thursday the eighty-seventh and eighty-ninth; on Friday the seventy-fifth and ninety-first; and on Saturday the hundred and forty-second and the canticle from Deuteronomy, which must be divided into two parts. But on the other days let there be a canticle from the prophets, each on its own day, according to the custom of the Roman church. After that, let the Laudate psalms follow; then a lesson from the apostle to be said by heart, the responsory, the hymn, the versicle, the canticle from the Gospels, the Kyrie eleison, and so the end.
