All but pp. 256-259, 265-268 and part of p. 198 are in the autograph of the grammarian Dr John David Rhys (1534-1609); his peculiar orthography begins on p. 13, l. 21. The poetical extracts vary in length from three to fifty lines. The lines selected are not always consecutive; they are even occasionally fragmentary, and many words are explained or glossed. The awdl on p. 256 is in a different but contemporary hand from that of Dr John David Rhys. For p. 265, cf. the text on pp. 22-24, which agrees in part. For the dating of this manuscript see p. 207.
