The “consideration” also clearly appears in the concluding portion of the Charter, where it is stated that in return for the foregoing gift of liberties along with those granted in the Forest Charter, the archbishops, bishops, abbots, priors, earls, barons, knights, free tenants, and all others of the realm had given a fifteenth part of their moveables to the King. The prominence given to this feature brings the transaction embodied in the re-issue of 1225 (as compared with the original grant of 1215) one step nearer the legal category of “private bargain.” It is, in one aspect, simply a contract of purchase and sale. Another important new clause follows—founded probably on a precedent taken from chapter 61 of the Charter of King John: Henry is made significantly to declare “And we have granted to them for us and our heirs, that neither we nor our heirs shall procure any thing whereby the liberties in this charter shall be infringed or broken; and if any thing shall be procured by any person contrary to these premises, it shall be held of no validity or effect.” This provision was clearly directed against future papal dispensations or abrogations, such as that which King John had obtained from Innocent in 1215. The clause, however, was diplomatically made quite general in its terms.[275] ----- Footnote 275: A few minor alterations, such as the omission of the clause against unlicensed castles (now unnecessary) and some verbal changes need not be mentioned. A list of these is given by Blackstone, _Great Charter_, l. ----- One original copy of this third re-issue of the Great Charter is preserved at Durham with the great seal in green wax still perfect, though the parchment has been “defaced and obliterated by the unfortunate accident of overturning a bottle of ink.”[276] A second is to be found at Lacock Abbey, in Wiltshire. The accompanying Forest Charter is also preserved at Durham.[277] ----- Footnote 276: See Blackstone, _Ibid._, xlvii. to l. ----- ----- Footnote 277: _Ibid._ ----- This third re-issue brings the story of the genesis of the Great Charter to an end. It marked the final form assumed by Magna Carta; the identical words were then used which afterwards became stereotyped and were confirmed, time after time, without further modification. It is this Charter of 1225 which is always referred to in the ordinary editions of the Statutes, in the courts of law, in parliament, and in a long series of classical law books beginning with the second _Institute_ of Sir Edward Coke.[278] ----- Footnote 278: One slight exception should be noted. In one point of detail a change had occurred since 1225; the rate of relief payable from a barony had been reduced from £100 to 100 marks. See _infra_ under chapter 2. -----
