Psalms are taken from Vespers 3 (Sunday). The Antiphons to the Psalms are proper to the Feast (D76) and are (of course) doubled. The Chapter and Hymn are also proper (D76-77). The doxology of this Hymn is repeated for all Hymns of the day which are of the same meter. The V./R. are for I Vespers (D77) as is the Antiphon to the Magnificat (D77). The Collect is taken from Lauds (D89). After the Collect the commemoration of the XIX is said. For this is used the Antiphon on the Magnificat and the V./R. for the XIX-th Sunday after Trinity (C645) and the Collect (C693-4). There are no Preces (Feasts of Double rite never take the Preces). The Suffrage is also not taken for the same reason. The Marian Antiphon is always said unless otherwise indicated in the Rubrics (Vespers of the Dead ends without it).
