At pp. 38, 39 we see a curious alteration in the value of the land, which had risen from xv. lib. 'quando recepit' and T.R.E. to xvii. lib. at the time the return was made, and dropped again to xvi. lib. in the Domesday Survey. This strange comment implies the supposition that the I.C.C. records an earlier survey than Domesday Book, whereas, of course, they are derived from the same returns, so that the discrepancy of xvi. and xvii. is merely a clerical error. One more instance, the 'curious reading' _Harlestone_ in the I.C.C., is shown below to be merely an error in that MS. Such are eight of the examples adduced by Mr Hamilton. The remaining two merely illustrate not the superior accuracy, but the greater elaboration of the I.C.C. It has been absolutely necessary to dispose of these examples, in order to show that a critical estimate of the value of the I.C.C. has yet to be made. Taking the omissions in the MS. first, we find some really bad ones. On fo. 79A (2), collation with Domesday gives this result: _I.C.C._ (p. 12)[12] _D.B._ (I. 196A) II. hidas et dimidiam et x. acras Tenuerunt ii. hidas et dimidiam tenuerunt. [..................... et x. acras. Nec isti potuerunt ................................. recedere absque licentia ................................. abbatis. Et xix. sochemanni, ................................. homines regis E., tenuerunt ....]. Non potuerunt recedere ii. hidas. Non potuerunt sine licentia. recedere absque licentia. A similar 'run on' omission is found on fo. 109A (1): _I.C.C._ (p. 79) _D.B._ (I. 200A, 193A) Tenet Radulfus de bans de [Widone Tenet Radulfus de Widone iii^{ciam.} de] rembercurt terciam partem partem i. virgatæ [Terra est i. unius virge. I. bovi ibi est bovi], et ibi est bos. Valet et terra, et est bos [.............. valuit ii. sol., et vendere potuit, ................................. et iiii^{tam.} partem unius Avere ................................. vicecomiti invenit. ................................. ................................. In Oreuuelle tenet eadem ................................. æcclesia iiii^{tam.} partem unius .......................] Valet et virgatæ. Terra est dimidio bovi valuit semper xii. den.[13] et valet xii. den. Another instance of 'running on' occurs on fo. 105A (1), where 'xviii. cotarii' (p. 67) is proved by Domesday to stand for 'xviii. [bordarii x.] cotarii'. Again on fo. 79B (2) we have this: _I.C.C._ (p. 14) _D.B._ (I. 195B 1) Eadiua unam hidam habuit et Tenuit Eddeua i. hidam et i. unam virgam [.................. virgatam et Wluui homo ejus ....] Socham huius habuit ædiua i. hidam et i. virgatam. Socam T.R.E.[14] ejus habuit Eddeua. So, too, on fo. 100B(1): _I.C.C._ (p. 52) _D.B._ (I. 190A)
