Bushrod Washington, Hunt v. Rousmaniere — Opinion of the Court
“ But we mean to say, that where the parties, upon deliberation and advice, reject one species of security, and agree to select another, under a misapprehension of the law as to the nature of the security so selected, a Court of Equity will not, on the ground of such misapprehension, and the insufficiency of such security, in consequence of a subsequent event, not foreseen, perhaps, or thought of, direct a new security, of a different character, to be given, or decree that to be done which the parties supposed would have been effected, by the instrument which was finally agreed upon. ”
