archy a royal library. Bound at the beginning of a volume catalogued Lit. O No. 38 is a fragment of early music printing consisting of eight pages measuring 15X Io cm., the four folios of which are numbered 41 to 44. Plate Ia shows the back of the front cover, with royal bookplate, the torn remnants of a page in scribal Latin used in the binding; and opposite, two tenor parts of an Ave Maria, each marked In diapenthe; at the bottom right is the printer's signature of a cross patee followed by ll.i. The next leaf contains the two parts of a Duo, with the text En disant une chansonnette, the right-hand page marked at the top with the Arabic folio number 42, at the bottom with the cross pat6e and ll.ii (Plate Ib). The following four pages are occupied by a motet, Christi virgo dilectissima, and its secunda pars, Quoniam peccatorum molle premimur (Plate IIa, b), the left-hand page of Christe virgo being marked Canon in subdiapason, the right Ad tertiam, while in the secunda pars the right side is marked Canon in diapason, and the left is unmarked, but canonic solution is implied by a signum congruentiae. The reverse of fol. 44 brings another piece with French text, En venant de Lyon (Plate IIIa), which has but one written part and three signa congruentiae. Finis appears in print at the bottom of the page. After this commence sixteen partbooks, all contratenors from collections printed by Pierre Attaingnant between 1528 and 153 I, the first in order being Chansons de maistre Clement Janequin Nouvellement et correctement imprimees a Paris par Pierre Attaingnant demourant a la rue de la harpe devant le bout de la rue des mathurins pres l'eglise saint Cosme (n.d), under which a hand has written Liber prinus Quattuor vocum cantiones, and still further below has begun to list the contents of the volume under German titles (Plate IIIa). There can be no doubt whatsoever
