ad p sai.mum: 
Cantate Domino canticum nouum; eia die, Domipne, eia. 1 
In this case the introductory trope Quem quoeritis in preesepe 
is accompanied, or completed, by a continuation of the trope 
within the Introit proper. This situation will he quite clear if 
we bring before us the complete Introit : 2 
In Die Hiatale Domini Stacio ad Sanctum Petrum. 
Incipiunt tropus antequam dicatur Officium: 
Quem queritis in presepe, pastores, dicite? 
Eespondent: Saluatorem Xpistum Dominum, 
infantem pannis inuolutum, 
secundum sermonem angelicum. 
Eespondent: Adest hie paruulus cum Maria matre sua, 
de qua dudum uatizinando Isaias dixerat propheta: 
Ecce uirgo concipiet et pariet filium; 
et nunc euntes dicite quia natus est. 
Eespondent: Alleluia, alleluia. 
lam uere scimus Xpistum natum in terris, 
de quo canite omnes cum propheta dicentes : 
Antiphonas soni vii: Puer natus est nobis, et filius datus est 
nobis: cujus imperium super Jiumerum ejus: et vocabi- 
tur nomen ejus, magni consilii Angelus. 
Ad Psalmum: Cantate Domino canticum nouum; eia die, 
Dompne, eia! Cantate Domino canticum novum, quia 
mirabilia fecit. 
The passage Cantate Domino canticum nouum; eia die, Dom¬ 
pne, eia, it appears, is a mere introduction to the Psalm-verse of 
the Introit. It seems likely, then, that the passage Ora est, 
psallite; iube, Domne, canere eia in the text above 3 is also an 
internal trope of the Introit in the form of an introduction 
to the Psalm-verse. 
Passing on to further variants of the trope under considera¬ 
tion, we find an interesting extension of the text in the fol¬ 
lowing : 
1 Followed by the rubric: Alios, indicating a fresh trope of the 
Introit. 
2 1 print the Introit itself in italics.
