Samuel Nelson, Farmers' Bank of Virginia v. Groves…
“ The notes and mortgage were executed and delivered accordingly, and the collateral securities surrendered, and the interest in them again exclusively vested in Collier; and in this way becoming the owner of the drafts and judgment against Groves, for which he had already received satisfaction, and bound himself to procure a discharge from the bank, the agreement with King, the principal debtor, operated instantly as an extinguishment of the demand: and placed it beyond the power of either Collier or the bank, or both of them together, to revive it by any subsequent arrangement. ”
