The only remanant of this chant is a rubric 'V' at the bottom of the left column; unfortunately, it is unclear what the rubric stands for. The other sources have the Responsory 'Post excessum' followed by a responsory verse ('Martinus episcopus' Cantus ID 601816a or 'Postquam sanctus' Cantus ID 601816b) which is followed by the second responsory for Matins ('Trigesimo ordinationis' Cantus ID 602346 or 'Ecce sacerdos' Cantus ID 006609).
