In Psalms, strings of words were missing, but were then inserted above the line or after the line by the same scribe. These additional words (often ten or twelve in a row) are written in the same hand, but smaller.
The manuscript is composed of one quire of eight leaves, five quiries of ten leaves each, and two quires of fourteen leaves each, one quire additional.
Layout: Psalms and the canticles are written in one column per page and 22 lines of text per page. Praise of Mary and Gate of Light are written in two columns.
