Six instrumental part-books, iv + 275, 279, i + 131, 200, 278 and 59 leaves, formerly pasted together in pairs (MSS. Mus. Sch. c. 64-69). Four different kinds of paper were used: first, watermark grapes (not in Heawood) for 3-part music in i, ii, and v, 8 quires of 8; second, watermark 'Pillar or Post' (slightly resembling H 3507) for 4-part music in i, ii, iv and v, 15 quires of 4; and for 6-part music in all parts, nearly 8 quires of 4, supplemented in ii and v by 3 odd quires of a third kind of paper, watermarked with Fleur de Lys (slightly resembling H 1722); in all parts of sextets, quires of 9-11 are of 8 of the first kind (grapes). 5-part music in i-v was copied on one or two quires of 4 of the third kind (fleur-de-lys), with two or one quire of 4 of the second kind (pillar or post), five quires of 8 of the first (grapes), and finally two quires of 8 and one of 4 of a fourth kind of paper (watermark grapes, slightly resembling H 2195, initials IPH). A second copyist using this paper added to the 3-part section of i, ii and v two quires of 4 containing Orlando Gibbons' fantasias. Blank quires of 8 of this paper follow the 3-part and the 4-part sections in all parts. Two sheets of the same paper complete the last quire (which is also blank) of the 6-part section in vi. End papers are of various kinds of paper. The leaves were much cut by the binder, but traces of an original pencil foliation, the same in all parts, remain. Bound, before 1641, in white vellum with pastedowns from a theological manuscript
