In the case of a person without power of representation concluding a contract as an agent of another, the other party may give peremptory notice to the principal demanding a definite answer as to whether he ratifies the contract or not, within a period reasonably fixed by the other party. If the principal does not send a definite answer within such period, he is deemed to have refused to ratify.
