According to this text the psalmody proceeds regularly 
through to the fifth psalm, or group of psalms: cxEviii (Lau¬ 
date Dominum), cxeix (Cantate Domino), and ce (Laudate 
Dominum). Of this group the first two psalms are sung regu¬ 
larly, without interruption. Before Psalm ce (Laudate Do¬ 
minum in sanctis ejus), however, is inserted the dialogue, 
which is repeated after verses 1 and 2 sung continuously, 
after verses 3 and 4 sung continuously, and after the final 
verse 5. This reiteration gives to the office a distinctly festal 
character. 
Quite as worthy of the feast is the practice revealed in the
