Acts which never take effect, as signing and acknowledging a deed of assignment of partnership property, but withdrawing assent before delivery,1 or acts done under duress, as giving a purchase-money note under duress,2 are not ratification. If A and B have been induced by X to convey land to him for a small fraction of its value by means of false representations made by X as to the quality and condition of land which he conveys in exchange for the land belonging to A and B, such contract is not ratified by agreement of A and B after they discover the facts to take a small amount of money and worthless land in addition to the original consideration, if A is slow-witted and understands the English language imperfectly while B is excitable and at times insane.3
