The uncial WD, a fragment of S. Mark, of the vinth or IXth century.

WD was discovered in 1862 by the late H. Bradshaw (Fellow of King's College, Cambridge, and University Librarian), in the Library of Trinity College, Cambridge, its slips (27 in number) being worked into the binding of a volume of Gregory Nazianzen: they are now carefully arranged between sheets of glass. They comprise portions of two sheets or four leaves (Folia 1, 4, 5, 8, the two inner sheets of an octavo quire being quite lost), containing fragments of Marc. vii. 3—4; 6—8 ; 30—36; 36—viii. 4; 4—10; 11—16; ix. 2; 7—9 in uncial letters of the ninth century (perhaps a little earlier) slightly leaning to the right. Each perfect column is 6 inches high by 3½ broad, and has 24 lines in single column on a page: the letters average about a quarter of an inch high. The ink is a yellowish brown. The (so-called) Ammonian sections stand in the margin, without the Eusebian canons, but a kind of harmony of the Gospels is given at the foot of the perfect columns, an arrangement which occurs also in Codd. E at Basle, Tb at S. Petersburg, M (partially), 262, 264 at Paris.
