Philip Pendleton Barbour,
Preston v. Keene — Opinion of the Court
“ An exchange is an executed contract: it operates, per se, as a reciprocal conveyance of the thing given, and of the thing received in exchange. Now, so far from this ground being taken in Keene's petition, it will be seem that his allegation is, that the Messrs. Brown, for a valuable consideration received, became bound, by the act of sale of the 21st of August, 1807, to convey and deliver to him a lot of ground, as described in his petition; whereas, the argument at the bar assumes, that the act of sale was itself the conveyance. ”
