It turns out that Caxton's text is of great value. He followed a MS. (now lost) which is, in some places, even more correct than MS. C. The following readings are of great importance, as they correct MSS. C. and A. (I denote Caxton's edition by the symbol Cx.)
Bk. i. met. 4. 7. Cx. writheth. (Cf. p. xlii. above, l. 6.)
Bk. i. met. 4. 8. Cx. thonder leyte[[44]].
Bk. i. met. 5. 26. Cx. punisheth.
Bk. i. met. 5. 28. Cx. on the nekkes.
Bk. i. pr. 6. 54. Cx. funden (but read founden).
Bk. i. pr. 6. 65. Cx. norissing. (Perhaps better than norisshinges, as in the MSS.; for the Lat. text has the sing. fomitem.) Cf. Bk. iii. met. 11. 27.
Bk. ii. pr. 3. 59. Cx. seeld (better selde). It is clear that yelde in MS. A. arose from a reading ȝelde, which really meant zelde, the Southern form of selde. See below.
Bk. ii. met. 3. 14. Cx. selde (correctly). And so again in Bk. ii. pr. 6. 15.
Bk. ii. pr. 6. 63. Cx. may I most. (MSS. C. A. omit I.)
