This manuscript contains an incomplete psalter in Latin, written in the 15th century, and of Dutch origin. It contains from Psalm lxxx, Exultate Deo, to end of Psalter. The ferial anthems are included passim, and the chapters, hymns, versicles, responses, and collects of the ferial day hours are added in their places after the corresponding sections of Psalm cxviii, Beati immaculati (Prime, f. 62r; Tierce, f. 68r; Sext, f. 71r; Nones and Compline, f. 78r), in smaller lettering and closer lines, often with cues only. The hymn Iam Lucis precedes Psalm cxvii, f. 55v, and Quicumque vult follows the section Retribue of Psalm cxviii, f. 59r. The last folios contain the Confitebor tibi domine quoniam iratus, followed by the other five Canticles said on week-days at Laud, and musical notation of the eight Psalm tones.
Psalter: starts on f. 2r with the following words: Exultate deo aduitori nostro. And ends on f. 98r with the following words: laudet dominum.

Miniature: On a rectangular square of vellum, pasted on f. 1v, and surrounded by a double line of colour with feathery branch work springing from each corner, within a medallion, the ground of which is punctured silver, is the half-length figure of a bishop in blue chasuble, lined with green, with gold Y-shaped orphrey, red dalmatic showing underneath, a white mitre and yellow nimbus. No apparel is visible on the amice. He holds a crosier in his right hand and a heart in his left.
