the donee's death, by the modus of the gift, by which it may be inferred that if  such heirs fail the thing given ought by tacit limitation to revert to the donor. And  by saying freely, he indicates his wish that no servitude be imposed on the  thing given, as where one to whom no servitude or use belongs attempts to exercise  some right in it. By saying quietly, it is his will that [the donee] have quiet and  peace, that he may use the thing given peacefully and be not inquieted. For quiet  is the same as repose or peace, and if the word quiet is compounded with the  preposition in the result will be inquiet, that is, lack of quiet. Nor does it matter  whether the donee cannot use [the land] at all or only with difficulty, as may be  seen below [in the portion on] the assises.1
Of services and customs to be performed.
 It is also said, rendering thence yearly so much at certain terms (such and such  terms, that is) and doing thence such services and such customs, which all ought to  be certain and specified in the charter, and having been so expressed and specified,  all others not expressed are taken to be tacitly remitted.2 Since the kinds of services  and customs are infinite, it would be impossible to set out in a charter everything  to which the donee is not bound, [and] though the charter does not acquit expressly  it does in fact do so since it does not burden specially.3 It is also said, for every  service, custom, secular exaction and demand, by which general clause the donor  is taken to remit expressly all other services, customs and secular demands that  belong to the lord from the tenement,4 though this is not expressly stated in the  charter. For some customs and services belong to the lord, some to the king, as suits  for doing justice by writ of right, for [preserving] the peace, as by judging a thief,  and for afforcing the court in such matters.5 Services belong to the lord, the donor,  because of the thing given, as rent, whether in gold or silver coins, as where it is  said, rendering thence yearly ten aurei, or ten argentei or ten shillings. Or if  the service lies in produce, rendering thence yearly ten cores (or ten quarters)  of wheat, or the like, if the service consists [in the render] of a solid; if of a liquid,  rendering thence yearly ten jars of wine (or ten flasks of oil). If things certain are  promised in return,6 [they may be promised conjunctively] or disjunctively, as  where it is said, rendering thence yearly certain gilt spurs or six pennies or one  pound of pepper or cumin or wax,
