Joseph Story,
Miller v. Stewart — Opinion of the Court
“ In truth, the assent of the parties to the alteration, carries with it the necessary implication, that it shall no longer be deemed an appointment for eight townships only; and the same consent of parties which created, is equally potent in dissolving the deed, and changing its original obligation. It is no objection, that to constitute a new deed, a redelivery is necessary; for if it be so, the consent to the alteration is, in law, equivalent to a redelivery. Nor is it necessary, that a surrender or revocation should be by an instrument to that effect. ”
