This last passage, of itself, is full of instruction. Firstly, the I.E. alone gives the value of the holding. Secondly, the I.E. preserves the 'sine socha' which qualifies the holder's right. Now D.B. gives the last clause as: Hi omnes terras suas vendere potuerunt. Soca tantum hominis abbatis de Ely remansit æcclesiæ. This qualification corresponds with the 'sine socha' of the I.E., and is, we should observe, wholly omitted in the I.C.C. Thirdly, the three versions of the original return employ three different words to express the same one--'recedere', 'vendere', 'dare'. Fourthly, the superiority of the C text of the I.E. over B (which makes two blunders in this passage) and of B over its offspring A (which adds a third) is here well illustrated. Fifthly, the phrase 'Picot vicecomes tenet eam sub abbate ely' differs notably from Domesday, which assigns the estate to Picot unreservedly, and still more from the I.C.C. which reads 'tenet Robertus de Picoto vicecomite in feudo regis'. The next example is taken from the township immediately preceding. _I.C.C._ _I.E._ V. istorum (sochemannorum) Fuerunt quinque sochemani homines abbatis de Ely fuerunt. Et T.R.E. unus istorum _sugga unus istorum i. virg. et dim. habuit. nomine_ habuit una virg. et Non potuit recedere. Et alii iiii. dim. sub abbate ely. habuerunt v. hidas et i. virg. Non potuit recedere. Potuerunt recedere sine soca (p. 95). _Et valet_ x. _sol._ Et alii iiii^{or} sochemani v. hidas et i. virg. tenuerunt de abbate eli. Potuerunt dare preter licentiam abbatis et sine socha et modo tenet eam Picot vicecomes de abbate ely _et valet_ iii. _lib._ (p. 112). I have said that in all these cases it might perhaps be held that the additional details found in the I.E. were not due to special information possessed by its compilers, but were derived from the original returns, though omitted by their other transcribers. It is possible, however, to put the matter to the test. If, anticipating for a moment, we find that we have, for the eastern counties, in Domesday the actual materials from which the compilers of the I.E. worked, we can assert that any additional details must have been supplied from their own knowledge. An excellent instance in point is afforded by Tuddenham, in Suffolk: _D.B._ _I.E._
